The Work menu is not shown on Word's default menu but can be added in any version of Word starting with Word 97. I see that any items I add to the Work menu get removed when I ran a CCleaner scan of Applications, including Office. If I do not include Office in the scan, then, of course, this does not happen.
I suppose there's no way to include Office in the Applications scan but elect to have CCleaner leave the Work menu as is. Am I right?
Apparently, the file involved in index.dat.
