Determine Microsoft Exchange CD Key from the Windows Registry
Have you ever come across an Exchange server that needed to have Exchange re-installed, but you couldn't find the original CD key for the installation? You can look into the Windows Registry and determine the key. Here is the location:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft Integration\*CRAZY HASH*\
Where *CRAZY HASH* is some random string of characters and dashes like 12A456B8-12AB-1234-ABDC-BC321CD123DA12
Inside that key you'll have a string with the name PID3.0 whose value is the CD key!
Default Password to Uninstall Symantec Antivirus Corporate Edition
If you have a computer that was at one time attached to a corporate network that is running a version of Symantec Antivirus Corporate Edition and you try to uninstall it, you'll see that there is a password required. The quick and easy answer to this question is to tell you that there is a default password, and it's symantec.
However, if the administrator changed the password, as any security-conscience administrator would, here are the steps involved in bypassing it:
Open the Windows Registry Editor (regedit) and browse to:
HKEY_LOCAL_MACHINE\SOFTWARE\INTEL\LANDesk\VirusProtect6\CurrentVersion\Administrator Only\Security\
Open the UseVPUninstallPassword key and change the value from 1 to 0
Close the registry and try to uninstall Symantec again. You should no longer be prompted for the uninstall password!
