Here's an alternative way to fix the WMF vulnerability.
Ilfak Guilfanov has published a temporary fix which does not remove
any functionality from the system (all pictures and thumbnails
continue to work normally).
Ilfak Guilfanov isn't just anybody. He's the main author of IDA
(Interactive Disassembler Pro) and is arguably one of the best
low-level Windows experts in the world.
The Temporary Fix can be downloaded from Here
It should work on all Windows 2000, all Windows XP(With or Without
Service pack installed) Computer.
Ilfak Guilfanov recommend that u uninstall this temporary Fix when
the patch is avaliable from Microsoft
