Aus http://support.microsoft.com/default...;en-us;Q322993:

The Microsoft Debugger Registrar for Java (Jdbgmgr.exe) is only used by Microsoft Visual J++ 1.1 developers.

If you follow the e-mail message instructions and delete this file, you do not have to recover it unless you use Microsoft Visual J++ 1.1 to develop Java programs on Windows XP, Windows NT 4.0, Windows 98 Second Edition, Windows 98, or Windows 95.

Falls du es doch wiederherstellen willst, gibts auf http://www.tu-berlin.de/www/software/hoax/jdbgmgr.shtml Tipps dazu.
