Windows Mail Fix for Slowness due to large Restricted Site List

[GTS]

Many users of Spybot (Immunize function) or SpywareBlaster or other programs
that add a large number of entries to Internet Explorer restricted sites
list experienced a severe performance problem in Windows Mail after running
the KB931768 critical update.

The following registry change resulted in an immediate return to normal
speed for a number of test cases. The following can be pasted to a .reg
file and run. Fix any word wrap so that the text from "[" to"]" is one
line.


Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet
Explorer\MAIN\FeatureControl\FEATURE_MIME_SNIFFING]
"winmail.exe"=dword:00000001

Sorry to hear it. This seems to work well for many (it cleared up the
problem my own PC as well as a few client machines immediately), but there
may be more than one issue causing Windows Mail performance problems.

This fix didn't work for me at all.. I am back to no entries in 'restricted
sites' and not running SpywareBlaster.. it's all up to Windows Defender
now..

Hi Mike,

It certainly works fine here. Without the winmail.exe entry, every operation in Windows Mail (Forward/Reply/New Message) took a 3 second delay in my system. I just double checked it for you, and can confirm that the FEATURE_MIME_SNIFFING setting really works.
