After installing the downloaded updates, Windows XP will automatically restart the PC, to apply all the updates.
This is not an issue and is by design. However, this has been addressed in Service Pack 2, where Windows XP SP2 installed PCs will install the downloaded updates at the time of restarting the PC. In pre SP2 systems, this feature is not available. The following registry modification will disable the auto restart feature.
It is always recommended to have a good backup of Windows registry before dealing with it. To know more about backing up Windows registry, visit:
Go to registry editor and navigate to the following registry key:
HKEY_LOCAL_MACHINE \Software\Policies \Microsoft\Windows \WindowsUpdate\AU
Change the "NoAutoRebootWithLoggedOnUsers" DWord value to the required number.
0 = False (Allow auto-reboot)
1 = True (Disallow auto-reboot)
Save and restart Windows Operating system.
