Most of that stuf is already done here except recommending disabling the system restore feature for one. For many users that could be disasterous if it becomes necessary to restore Windows often due to a bad install of some new program. Autoupdates is already disabled here since a periodic trip to the MS update page takes care of that. And in the earlier XP days you would 512mb of memory or more on custom builds. Prebuilds would see 128mb to 256mb there. I ran 1gb of ram with 98 with a simple tweak in the autoexec.bat file by adding one line in there.
yeah. I leve system restore on for only my c drive. there's maybe a couple of more things on that list that I ignore like windows sounds. I do disable windows sounds when I'm recording something in the background off of a website, record player or tape deck
