W7 Pro SP1 64bit

Click on these three icons/buttons to filter out some events:

Make the column named Operations much narrower.

Make the column named Details much wider.

Or, try to zip and upload the entire log file as an attachment to a post. You will need to tell me the time that you pressed the Alt key.

Please do as UsernameIssues suggests, but try this too:
Download and run KeyCastOW (no installation needed) -

It will show you what keys are pressed, then try your ALT key and see if something else registers (try in Safe Mode too to see what is the normal behavior).

Even though you said you performed a clean startup (using msconfig), did you disable non-Microsoft services too?
