If you use Microsoft Office Communicator as your internal messaging solution, you might frequently be annoyed by the fact that you can’t just click on URLs that your workmates send you. You can click on URLs in MSN Messenger, but not in Communicator (by default). This is no end of hassle if you get frequent links to great web comics.
The fix is a tiny tweak to your registry:
Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Communicator] "EnableURL"=dword:00000001
Done! Now you can happily click away on those links.
