How to Change the Interval of the Windows Critical Update Notification

If you install the Windows Critical Update Notification from the Windows Update Web site, it is scheduled to run every five minutes in Task Scheduler. If you change the value to another time period and restart your computer, the time period changes back to five minutes. To change the time interval:

Start the Registry Editor
Go to HKEY_LOCAL_MACHINE \ Software \ Microsoft \ Windows \ CurrentVersion \ Run
The defaul value for the CriticalUpdate value is C:\Windows\System\wucrtupd.exe -startup, delete the -startup portion, and change wucrtupd.exe to Sucrtupd.exe so that the CriticalUpdate value reads: C:\Windows\System\Sucrtupd.exe
Close the registry editor
In the Task Scheduler, change the interval for the Windows Critical Update Notification task to the interval you want
