But in Vista and Windows 7 you can easily disable the automatic driver updates. Just follow these steps:

• Open the Control Panel
• Select System and Maintenance
• Select System
• Now click Advanced system settings in the left-hand panel (if the UAC is turned on, click Continue to proceed)
• Next, click the Hardware tab
• Click the Windows Update Driver Settings button
  

Now you need to select the driver update option you want to use.
The default option will automatically check for drivers and update them. To disable automatic driver updates in Vista, select either the second or third option and click OK.

In some cases this appears not to work, and then there is another method to disable automatic driver updates in Vista and Windows 7. This involves the local group policy editor, which can be started from the Start meny by typing “gpedit.msc” followed by Enter.

Once started, in the Local Group Policy Editor, navigate to the following: Computer Configuration -> Administrative Templates -> System -> Driver Installation.

Next, change the setting for Turn Off Windows Update Device Driver Search Prompt
to Enabled. After clicking OK and closing the Local Group Policy Editor, just restart and that’s it.

Since the Local Group Policy Editor is used, this second option is limited to the Professional and Ultimate editions of Windows Vista and Windows 7. The Home versions do not have this option.

Due to the size and complexity of the printer software, the installation will normally include a setup or install program. Running this and following the installation instructions (to the letter) will install the printer on your Windows Vista computer.

Updating a Printer Driver in Vista

The large printer manufacturing companies, like HP, use in-place update software these days, so you will automatically be notified of updates. Installing the printer driver update is then also done for you. But not all manufacturers have such sophisticated processes in place, and you also should consider if you want to run all these automatic schedulers on your PC.

If you want to manually update your printer driver in Vista, is is possible to use the same installation procedure as used for the initial installation. That is, download the printer driver update for Vista and run the setup or install program.

It can be possible  to first uninstall the existing printer software though. What is important is if the printer driver update software is a full install, or an update. When you download a printer driver update for Vista, the website of the manufacturer will mention this type of information in the release notes. If it is a full installer, you can first try running it, but if it fails, simply uninstall the printer software in the Control Panel first. Then reboot and try it again.

If the installer does not work, or there is no setup or install program, it is possible to manually update the printer driver in Vista. This process is outlined below:

First open the Control Panel from the Vista Start menu.

Next, click the Printer link under the Hardware and Sound category.

Now select and right-click the Printer for which you want to update the driver.

1. In the popup menu, select Run as administrator, and in the submenu, select Properties.
   
2. If the UAC comes up, click Continue.
3. Next, click the Advanced tab, and then click the New Driver button.
   
4. In the Add Printer Driver Wizard, click Next, then Have Disk and finally Browse.
5. Now navigate to the location of the Vista printer driver update, and then click Open and OK.

This process will use the driver information file (.inf) to find the printer driver update and install the required driver files onto your computer.

Don’t forget to turn on your printer when you update the printer driver. It is easy to forget since the printer will show in the list, but it will be grayed out rather than show in black. But the printer should be turned on to allow communication between Vista and the printer, otherwise the driver update installation might fail.

That sounds pretty simple, doesn’t it?

Well, in a way it is, but still it is possible that a driver update program recommends a program that should not be installed on your system. We call this a false positive. There are two possible reasons for a false positive in driver updates, a device mismatch and a driver version mismatch.

Device Matching Logic

In order to understand, we need to look at how a device is identified in Windows. If we open the Device Manager, select a device and then right-click it to see the Properties, we can select the Details tab. In the list of properties, we select the Hardware Ids:

As you can see in the screenshot, a device can have multiple hardware ids. The top one in the list is an exact match of the device, where the brand, model, type and even revision number would match. Going down the list, the device match is broader, but still specific, that is why all these identifiers are present in the list of hardware ids.

But Windows allows for the use of compatible drivers, so that, if an exact match on the driver is not available, the device can still be used with a compatible driver. This may result in reduced support for the device, not all functionality may be available, but at least the device works.

If we select the Compatible Ids in the property list for the same device, we see:

Again, we see a list of identifiers, where the top one would be the preferred match, and the lower ones are broader matches.

When a driver is needed for a device, Windows will always first try to find a driver for the device based on a hardware id match. If none can be found, a driver match based on the compatible ids can be used.

So if an existing driver has a match on a hardware id, while an update is recommended that matches on a compatible id for the device, we consider that a false positive.

Driver Version Comparison

Apart from a list of devices that is supported by a driver, a driver also has a date and version. The date and version are actually combined in a single identifier, like:

“03/22/2010,6.236.0322.2010”

The first part is the date, and the second part is the version number. Windows checks for new drivers based on the driver date, the version is optional. So if a driver program recommends a driver update based on a newer version, while the date is older than the currently installed driver, this is again a false positive.

In the Device Manager, you can select the Driver tab to see the date and version of the currently installed driver:

Drivers do not always have complete date and version information, and even the date format is not always consistent. Driver programs obviously need to factor in these aspects when recommending driver updates.

In our tests, we found DriverFinder to have the best device driver matching logic.

So when you are looking for a device driver for a piece of hardware, it is useful to know the hardware id of the device. This can tell you which manufacturer made the device and help you find a device driver.

The Windows Device Manager

The hardware id for a device in Windows can be found in the Windows Device Manager. To check the hardware id for a device, follow these steps:

1. Open the Device Manager from the Control Panel. You can also type “devmgmt.msc” at the Run option in the Start menu.
2. In the Device Manager, right-click the device, and select Properties in the popup menu.
3. Next, select the Details tab.
4. Now select the Hardware Ids in the dropdown list.

As you can see in the screen shot, there can be multiple hardware ids for a device. The top one is the most specific identifier, and going down, the identifiers are more generic. The reason this is done is to allow a device driver to be selected based on a match to any of these hardware identifiers.

The hardware manufacturer in this example is Realtek, which is identified by VEN_10EC.

Obviously this is a device for which a driver is installed already, and the manufacturer and model for the device are shown, but the hardware id is also available for unknown devices and not recognized devices.

Driver finder programs use the hardware id and the compatible id to find a matching driver for a device as well.

So if you are getting unexpected errors indicating device not recognized, check the device path in the Windows registry. If the %SystemRoot%\Inf value is not present in the DevicePath, then change it or add it.

The DevicePath variable can also be extended with additional locations for drivers. If for example, you have a network location where you store device drivers for all PC’s and hardware devices, you can add that to the variable. Just separate the path with a semicolon. E.g.: %SystemRoot%\Inf;\\\\Drivers

OEM manufacturer’s also use this option to include additional drivers in the default Windows setup.

Of course, always make a backup of the Windows registry before you make any changes!

Still can not find a device driver? Use DriverFinder to locate drivers for you automatically.

As a result, you can experience a variety of device errors in Windows 7, one of which is device driver error code 10. In itself, error code 10 in Windows 7 means that the device cannot start, but there can be different causes for the error.

Microsoft’s recommendation is to first update the drivers using the Device Manager. This should help solve problems that are related to outdated, incompatible and even corrupt drivers. But also make sure you install the latest Windows 7 updates, as software improvements in the operating system can also help fix device related issues.

Ok, an error code 10 can happen for all kinds of devices, and one of the more common devices is the audio device. Apart from driver issues, also make sure you check the status of the Windows Audio service. If the Windows Audio service is not running, you can have the right drivers installed, but the device will not work.

For USB devices the error code 10 will result in the device not being accessible. In that case, uninstalling USB devices in the Device Manager is a common solution. You can try uninstalling the USB device that has the problem, but very often it is necessary to uninstall all USB devices, reboot and then wait for the USB devices to be reinstalled. Make sure to unplug the external USB devices before you reboot, so you can add them one by one again.

For older hardware, the code 10 error can also be the result of hardware conflicts. In most cases, you will see that the hardware device will not appear on the hardware compatibility list, but it is useful to check the resource usage on the device in the Device Manager. On desktop computers, this kind of problem can be solved by changing the BIOS settings (IRQ assignments, memory ranges), or even unplugging conflicting hardware. Obviously that is only feasible if you do not need that specific device.

Windows 7 Device Drivers

Since the most common cause of error code 10 in Windows 7 is incorrect device drivers, you should always try to get the right drivers for the device. Checking on a regular basis can pay off, as drivers are updated frequently. Using the Microsoft Update feature is one way to check, but there are a number of limitations with that.

The first limitation is that you will only get real Windows 7 drivers, which are signed drivers that have the Microsoft approval. You will not get unsigned drivers or drivers that are not for Windows 7. So if there is a Vista driver for your device, which might work in Windows 7, you will not get it. Even Windows XP drivers sometimes work in Windows 7, possibly in compatibility mode.

The second limitation is that Windows Update will automatically install new drivers. This assumes that the update will succeed without problems, replacing or overwriting the old driver. In quite a few instances however, it is better to first uninstall the existing driver before installing the new driver. Quite a few audio manufacturer’s recommend this practice to prevent driver update problems.

So make sure you use a variety of methods to update the driver for your device and fix error code 10 in Windows 7.

If there is no driver for the device, or the device is not recognized, you will be informed of that fact as well. In some cases the driver installation and device activation actually will show several of these popup messages in the notification area. This can be the case if the USB device has multiple functions.

Unfortunately there are also scenario’s where these popup messages in the notification area do not seem to make sense. No USB device is being plugged, only existing USB devices are present, or maybe no external USB devices are present at all.

If you are not interested in the USB notification messages in Windows, you can actually disable them. Basically you tell Windows to not report and USB errors on the USB controllers.

To disable USB notification messages, simply open the Device Manager in the Control Panel and open up the branch called Universal Serial Bus Controllers.

You will see quite a few devices in the list, but we are only interested in the Host Controller devices. Right-click the first entry and select Properties in the popup.

Next, select the Advanced tab and then select the checkbox named Don’t tell me about USB errors.

Click the OK button and repeat these steps for the other Host Controller devices.

When you are done, close the device manager and you should no longer see and USB device notifications in the Windows taskbar.

Keep in mind that if you were receiving the USB notifications because of real USB errors, they will be now be ignored. If possible try to address the errors first. Power management and bad cables (connections) can also be the cause of erratic USB notification messages.

In Vista for example you would see the message below indicating that Windows can’t verify the publisher of this driver software.

But what is the difference between signed and unsigned drivers?

A signed driver is basically a digitally signed driver, which means that the driver software is associated with a digital certificate that allows identification of the publisher of the driver. It also ensures that the driver has never been modified by anyone else, as that would corrupt the signed status and make it unsigned.

So using a signed driver will ensure that Windows can automatically install the driver and prevents malicious software to be installed along with the driver. Considering that drivers operate at a very high security level in the operating system, it is very important to use safe drivers.

Windows Vista, Windows 2008 server and Windows 7 already enforce unsigned drivers to be installed using administrator level access, but how can you know for sure that an unsigned driver is safe?

Well, you cannot really. So always make sure that your security software is up to date and active, and make a backup or create a system restore point before you make any changes to your system, especially when installing device drivers.

Verify unsigned drivers in Windows XP

In Windows XP, the enforcement of signed drivers is not present, so the risk of installing unsigned drivers with all associated risks is much higher.

One thing you can do in Windows XP is to find the unsigned drivers in Windows XP and, if possible, replace them by newer, signed drivers.

Microsoft has detailed instructions on how to use the Windows XP Signature Verification Tool to check the unsigned driver files. This also describes the common problem with power management in unsigned drivers, so you can try to update or replace the unsigned drivers by signed drivers, or disable the unsigned drivers if they do cause such problems.

Disable Unsigned Driver Warnings

It is not something we recommend, but as a user you can actually disable the warnings regarding unsigned drivers in Windows XP. Right-click the My Computer icon, and select Properties in the popup menu. Now select the Hardware tab, and click the Driver Signing button. Next, select the Ignore option and click OK.

If you are using Windows XP Professional, you can also change the security policies to do the same.

Type “secpol.msc” at the Run option in the Start menu and press Enter. Then browse to Local Policies -> Security Options. Now find and change the option “Devices: Unsigned driver installation behavior” to “Silently succeed”. This requires a reboot of the computer.

Use unsigned drivers in Windows 7

Windows 7 will not allow you to install unsigned drivers as well. Although it is good to protect an operating system from installing potentially unreliable drivers, in some cases there simply are no signed drivers available, and the unsigned drivers are the only way to make a device work.
In Windows 7 you can disable driver signing from the Start menu (F8), but that will need to be done during each boot.
Other options are to use the Group Policy editor, which will work for the Ultimate (and I also believe the Pro versions):
- start the Group Policy Editor using the gpedit.msc command on the start menu.
- select User Config -> Admin Templ. -> System -> Driver installation
- select IGNORE in the dropdown box

If the Group Policy Editor option is not available, you can use this method:
- start a command prompt with admin rights (right click and select Run as Administrator)
- type bcdedit.exe -set loadoptions DDISABLE_INTEGRITY_CHECKS and press Enter
- type bcdedit.exe -set TESTSIGNING ON and press Enter

After this you should be able to install unsigned drivers in Windows 7.

In case you want to revert the changes, use DENABLE_INTEGRITY_CHECKS as the last option in the first command and OFF instead of ON in the second command.
To update your drivers in a few simple steps, you can use a driver update tool.

But of course a driver update can occasionally also cause a problem in your system. A conflict with another hardware device can be the result, or the device suddenly can not be used in some programs anymore. Beta drivers can have this effect, since they need to be tested more.

Revert Back to the Previous Driver

Luckily Windows offers the possibility to restore the previous version of a device driver in most cases. Windows XP, Vista and Windows 7 all have the functionality that a driver backup is taken whenever a new driver is installed, so it is possible to restore that driver from the backup. This is called a roll back in Windows.

To do a driver roll back, open up the Windows Device Manager. You can access it in the Control Panel, or type it in the search field of the Start menu for “device manager” and click the resulting program.

In the device manager, you need to right-click the device for which you want to restore the previous driver version. In the popup menu, select Properties.

This will bring up the Properties window for the selected hardware device. In the device properties window, select the Driver tab. Now you will see the driver details and a number of buttons with driver functions.

The next step is to click the Roll Back Driver button. You will see a confirmation message, where you need to click the Yes button.

Some notes on this procedure:

• Make sure you are logged in as a user with administrator privileges.
• You can only roll back to one previous version of a driver.
• The driver roll back feature is not available for printer drivers. In that case you will need to download the older version of the printer driver and install that driver.

With many homes now having multiple PCs and using them for entertainment purposes, networking is becoming more common. Messages can be sent from one PC to another while any data, such as music and videos, can be distributed around the network. A more informal type of network is the internet, with millions of computers around the world being able to connect to numerous sites.

Whilst internet connections are via a modem or router, PCs need a network interface card, either built into the motherboard or inserted into a slot. Each of these cards has a network driver, which is a form of device driver or PC driver. This handles all communication between the computer’s operating system and the network card so that it can interface with other points on the network.

Why We Need Network Drivers

There are a bewildering number of network cards available from a variety of manufacturers. Each of these may be fitted into various motherboards and there are several different types. Many are PCI cards, although 10/100 types are the most common and Gigabit cards are now providing additional speed. Although relatively new, wireless networking is becoming increasingly popular. This is especially true in home networks where it reduces the need for unsightly wires.

All these options make it impossible for the operating system to deal with the many combinations. This problem is overcome by the use of network drivers, which are developed specifically for each network card and have versions for the different operating systems. A network driver provides a link between the operating system and the network card. Its role is, like any other device driver, to interpret the high level commands issued by the operating system into a form that the network card can understand and conversely to translate network card messages for the operating system.

A network driver needs to be more adaptable than any other device driver because, not only does it have to deal with requests from the operating system, it can also receive packets of data from anywhere on the network. Additionally, it has to handle a number of administrative tasks such as compiling traffic and error statistics, setting addresses and modifying transmission parameters.

Why You Need to Update Network Drivers

The efficient operation of a network is vital because problems can impact on the whole network rather than simply affecting a single PC. A network fault on one computer can cause a bottleneck that brings the whole network to a halt or at least slows its performance.

Problems are often due to faulty, out-dated or corrupt network drivers and so it is important that you install new drivers as they are released. Manufacturers generally develop new drivers to fix known faults, improve security or to provide enhanced performance and so you should take advantage of these features.

To install new drivers, access Device Manager. Depending on the operating system you use, this may be available from the Control Panel or by right-clicking My Computer then choosing Manage.

Device Manager will list the types of device in the right pane and you need to select Network Adaptors and the network card you have installed. Right click it, select Properties and then the Driver tab. Afterwards, click the Update Driver button to download drivers and install the latest version on your PC. When you complete the process, restart your computer.
