wuauclt.exe

Sometimes a box appears (as much as every 5 seconds) advising that "wuauclt.exe has encountered a problem and needs to close. We are sorry for etc" and asks if I want to send an error report. This has persisted even after returning to factory state.

This is the windows updator process. Do a full scan for virus and spyware as they sometimes target this process.

Is this occurring 3 times "every so often", or if you check for Windows Updates manually?

Check in the Application event log for Application Error events (1000) to see if there's any more detail on the crash:
Start / Run
Enter: eventvwr
Drill down to Windows Logs / Application
Scroll down the list looking for the Source "Application Error" - highlight an entry and look on the General tab

The event log shows 21 x application errors cat (100), event 1000, user n/a, computer betwwen 1720 -1725:

Is the information in the General tab (mostly) the same for each of the Application Error events?

Can you copy/paste here a handful of contents of the General tab from some?

Thanks for help. It seems that the problem has stopped. I have run a couple of scans but nothing found. Perhaps I could come back if it reoccurs. I have learnt a little from this. Thanks again.
