The path to fixing Windows Update Service
I often need to trouble shoot Windows Update issues. I have found that some of the following things are useful to know in regards to trouble shooting:
- Review this KB How to troubleshoot common Windows Update, Microsoft Update, and Windows Server Update Services installation issues
- Try looking at WindowsUpdate.log (click for more info)
- Use wuauclt.exe tool to force the update detection
MS Page for wuauclt utility
Yet another incomplete document
- RegKeys
Create the required DWORD values from table below:
Value: NoAutoUpdate
- 0 – Enable Automatic Updates (Default)
- 1 – Disable Automatic Updates
Value: AUOptions
- 2 – Notify for download and notify for install
- 3 – Auto download and notify for install
- 4 – Auto download and schedule the install
Value: ScheduledInstallDay
- 0 – Install every day
- 1 to 7 – Install on specific day of the week from Sunday (1) to Saturday (7).
Value: ScheduledInstallTime
- 0 to 23 – Install time of day in 24-hour format
Note: I finally decided to run strings.exe (click for more info) against the exe and here is the list of the flags I found (you can guess what they are for:)
