I might have posted this before, but if you want to change the amount of time that windows give you between suggsting that you reboot following the recent windows update, you can do the following (care of Microsoft):
1. Click on Start and then click on Run.
2. Type in 'GPEDIT.MSC' without the quotes and click on OK.
3. Within the Group Policy Editor, navigate to 'Local Computer Policy / Computer Configuration / Administrative Templates / Windows Components / Windows Update'
4. On the right hand pane, double click on the policy named 'Re-prompt for restart with scheduled installations'.
5. If the automatic computer restart prompt needs to be completely disabled, select "Disabled" and click on OK.
6. If the default time interval needs to be changed from a value of 10 minutes to some other value, select "Enabled" and type in the desired time interval in minutes in the following box. Click on OK.
7. Restart the computer for the changes to take effect.
You can, if you wish, disable the reminder instead of changing the timeout.
Usual caveats apply - don't do this if you don't know what you are doing and remember that if you don't reboot, your machine is not properly protected.
