"The fix for Windows XP not letting you delete .avi

I've seen this coming up more and more all over the place so I figured I'd
stick it here.

Avi files (divx) can be trouble in xp. there is a fix to let xp behave much
better so it's possible to move or delete large avi files. The obnoxious bug
in XP that causes Explorer to read the entire contents of broken AVI files
before allowing any access to them is caused by bad behavior of shmedia.dll.

To correct this misbehavior in Windows XP, remove the following
registry key.

HKEY_LOCAL_MACHINESOFTWAREClassesCLSID{87D62D94-71B3-4b9a-9489-5FE6850DC73E}InProcServer32

This will prevent Explorer from loading shmedia.dll in response to file
property queries on these files.

Just an extra note, if you do a "search" for this key it will not be found,
look for it manually it is very easy to find. As always newbie or not, if
you FUBAR your registry its your own fault. This fix does work, I use it and
have applied it to many XP machines. Now go ahead and fix this royal pain in
the ass! "

Eso lo arregló en mi caso

Salu2!
