Nothing else I did was working. I had clicked off that stupid checkmark next to Automatically Open Clipboard at least a dozen times. I had clicked off every other checkmark I could find. Every time I went into Excel and copied a couple of times the @#*& Clipboard would open up AGAIN. It looks like you’ve found a way to get the job done. I just wish Microsoft Office would have honored my first attempts to turn off the clipboard. It shouldn’t be that hard.

Close all Office applications, including Outlook, before performing any of the following registry edits.
To Disable clipboard:
1. Click Start | Run
2. Enter “regedit” in the Open field
3. Click OK
In the Regedit window:
1. Navigate to: HKEY_CURRENT_USER\Software\Microsoft\Office\[version]\Common\General
Where [version] corresponds to your Office version: 9.0 = Office 2000, 10.0 = Office XP, and 11.0 = Office 2003.
2. Locate the DWORD value AcbControl or create the value if it does not exist.
3. Set the AcbControl value to 1. (Set the value to 0 to enable the dialog box.)
4. Close the Registry Editor and restart an Office application.
