Windows Script Host Error Dialog Popups in the morning

hostsscriptvbscriptwindowswindows 7

A few days ago when I resume my computer from sleep mode in the mornings I would see an error dialog from "Windows Script Host" that read: "There is no script engine for file extension ".vbs". I am having hard time tracking down the source of this. I've looked through the event log, registry, and the scheduled tasks. But the lists are so long and I don't know where exactly to look for.

Details: It looks like it happens once a day and I only see it in the mornings. I'm on 64-bit Windows 7 Home Premium.

Any pointers are appreciated.

also, i think this started after one of those automatic windows updates.

You may want to look in your Scheduler to see what sort of stuff is trying to run every morning. Doesn't hurt to be paranoid.

The root cause of the problem is that you installed something (most likely an editor.. UltraEdit did this to me) that took over the .vbs extension. Open up Regedit, go to HKEY_CLASSES_ROOT.vbs and reset the default value to "VBSfile" (no quotation marks).
