Sometimes it happens that when installing new version device drivers, such as a video card, the system becomes unstable. Naturally, this is unacceptable, since it creates a lot of inconvenience. Everything is made worse by the fact that, as a rule, distribution kits of old drivers of this device are not saved anywhere and it is impossible to install them again.
The developers of the Windows XP system foresaw the described situation and provided the system with an appropriate mechanism. This mechanism allows you to do a so-called driver rollback, which makes it possible to restore functionality operating system. This is possible because whenever critical system components are replaced or updated, the operating system stores the replaced files in a special hidden folder and keeps a record of all actions. To restore the system, you must use this particular protocol.
So, let's say you need to roll back a poorly installed or incompatible video card driver that causes unstable work operating system.
First of all, you need to open the system properties window to access the list of installed devices. There are several ways to do this. One of them is to click right click mouse on the My Computer icon and select Properties in the menu that appears (Fig. 5.6).
Rice. 5.6. Select Properties
As a result, the System Properties window will appear on the screen, containing several tabs. In this window, go to the Equipment tab (Fig. 5.7).
Rice. 5.7. Contents of the Equipment tab
This tab contains several areas with buttons. When you click the Device Manager button, a window of the same name will appear on the screen, which displays a list of all devices in this moment installed on your computer. By clicking on the plus sign next to Video adapters, select the installed video adapter. Right-click on it and select Properties in the menu that appears (Fig. 5.8).
Rice. 5.8. device Manager
In this case, the properties window for the installed video adapter will appear on the screen, containing several tabs (Fig. 5.9).
Rice. 5.9. Properties window for the installed video card
In this window, go to the Driver tab (opened in Fig. 5.9) and click the Roll Back button. The system will issue a warning asking you to confirm the awareness of your actions (Fig. 5.10).
Rice. 5.10. We confirm our actions
After clicking Yes in this window, the system will roll back to the previous driver installation. This may take some time (depending on the complexity of the installation). In any case, after this process is completed, a dialog box will appear on the screen (Fig. 5.11), informing you that the system parameters have changed and you need to restart the computer for the new settings to take effect.
Rice. 5.11. Driver rollback is complete. Requires computer restart
At this point, the driver rollback can be considered complete. If your system is still unstable after restarting your computer, restoring your system using a restore point may help. You will read about how to restore the system in the next subsection.
Some updates cannot be installed while the operating system is running, so sometimes Windows Update will ask you to restart your computer to complete the installation. How do you say? No time? Of course, you can postpone the reboot, but get ready for the next reminder to pop up within five minutes.
In the second reminder window, you can postpone the reboot for another four hours, but, unfortunately, there is no “stop pestering me” button. To get rid of the reminder window at least until the next reboot, open the services window (Services, services.msc), highlight Center Windows updates(Windows Update) and click on the square Stop service button located on the Toolbar. Don't worry, Windows will start it again when you finally have time to reboot.
A more complex method allows you to completely get rid of the reminder window;
1. Open the Registry Editor (see Chapter 3) and navigate to HKEY_LOCAl_MACHINE\SOFTWARE\Policies\Microsoft\Windows.
2. Inside Windows partition create new section named WindowsUpdate.
3. Now, inside the WindowsUpdate partition, create a partition named AU.
4. In the new AU section, create a DWORD (32-bit) value named NoAuto-RebootWrthLoggedOnUsers.
5. Double-click the NoAuboRebootWithLoggedOnUsers parameter, enter 1 in the Value field and click OK.
6. Restart your computer for the changes to take effect.
To revert the changes, simply remove the NoAutoReboot-WithLoggedOnUsers setting.
