How to stop unexpected
Windows XP reboots
If you use
Windows XP Pro, you can use a little-known setting to turn off the auto-reboot
feature of Automatic Updates. This way, you can configure Automatic Updates to
download and apply patches automatically at night, which is good for your
security. But AU won't reboot your PC. Instead, a reminder to reboot will be
displayed. If you set AU to apply patches at 3:00 a.m., which is the default,
you can reboot first thing in the next morning when you're not in the middle of
a project.
The best way to change this setting is using Windows XP Pro's built-in Group
Policy Editor (it doesn't exist in XP Home):
Step 1. Click Start, Run, enter gpedit.msc, then click OK.
Step 2. In the window that opens, click the plus signs in the left pane
to navigate to the following folder, then select that folder:
Computer Configuration \ Administrative Template \ Windows
Components \ Windows Update
Step 3. In the right pane, right-click No auto-restart for scheduled
Automatic Updates installations, then click Properties. In the Properties
dialog box that appears, select Enabled, then click OK and close the Group
Policy Editor window.
You can also delay or lengthen the amount of time between reboot prompts by specifying the amount of time under the “RE-prompt for Restart with Scheduled Installations” setting.
