After installing the latest version Win Zip10 I started getting the
display of the Common Folder when the PC boots up. There is nothing in
it. I can close it. The operation of the PC is not affected. After
checking around including Microsoft I found one Knowledge Base article
(Q170086 that sort of refers to it, but the two registery keys it
identifies as the culprits are clean. Some of the entries have quote
marks others don't, but all that do have quote marks have then in place
at both ends of the string. I didn't find any single quote marks.

The Registery Keys are:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Curr entVersion\Run

and

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Curr entVersion\Run

I'm assuming that something is corrupted in yet another registery key.
What other keys should I check and what should I look for in them?
