Failed to Register Server?

I recently installed a new hard drive, and copied everything over from my previous drive.  Now, when I start programs in Windows, like paintbrush, media player, and the like, including MS-Word, I get a message that says "Failed to Register Server".  I click 'OK', and the programs seem to run fine, but I imagine that I wouldn't be able to use OLE, not to mention that it is pretty annoying.

I tried reinstalling Windows, but I continue to get the same message.

Any ideas or advice would be greatly appreciated.  Thanks!!!
