I'm in an organization which having much older desktop PC running using windows9x (thats including windows 95, 98, ME).
We introduction client/server base antivirus. (Trend Micro SMB). It's require to update windows patches as up-to-date.
Thats much effort needs to be done when user needs to download from windowsupdate.microsoft.com. I don't trust the users.
I being use autopatcher from www.autopacher.com since 2003 to cut time for patch downloads. Now M$ urge to stop them Aug 2007.
It is sad and pain for me.
