Yeah, nice and informative.

Just to add for those of you who want to disable RFC a word of warning, I disabled it to see if I could get by without it and PGP could no longer work, as well as ICQLite, and I had to restore the services via editing the registry as the Win2k Services under control panel would not show me any properties.

If you have a microsoft OS that is still supported then you simply need to open windows update and anything not installed should appear when you scan for updates. If you happen to be using Win9x and I think both 98 and 98SE have been discontinued, then you have to manually check which hotfixes you have installed and download them. I've recently done work on a few WinME systems at my work and windows update is still supported for that so anything newer should still work. I forget where I read the actual time frames but they have the amount of time that windows update will continue to work, along with when they stop selling and I'm not sure but I believe they will stop giving customer service as well after a certain number of years.
