Thank you for responding. Whenever I reinstall Windows Me, it's from the DOS level. I use a Windows Me startup disk and then the LIST utility (www.buerg.com) to browse to my installation path on my hard drive where my WinME CD is backed up in its entirety. C:\ADMIN\WinMeOem\setup.exe This method helps in the event that my CD drives are not available for some reason, and it prevents me from having to put the CD in during Windows Updates or adding new hardware. I always replace my existing OS, as you suggested, but this does not replace ALL the files. It replaces most Windows files but may not replace those put in by other programs. It is not always possible to uninstall IE 6 SP1 or WMP 9 before reinstalling Windows. Read my initial post for a description of potential problems I face when IE 5.5 overwrites IE 6 SP 1 during the reinstall. When that happens, I can't always put IE 6 back on there. Sometimes I have to put IE 5.5 SP2 on there first before IE 6 SP1 will install again. That's why I asked about the full service pack update (not an active setup installer) for IE 5.5 SP2 rather than the full browser for IE 5.5 SP2. Reformatting the hard drive is PRECISELY what I'm trying to avoid. I can't be doing that every month or every few months. It's too much work, and it causes activation problems with Norton and other software. It's time I learned some workarounds for babying Windows Me, since I'm going to be stuck with it for a while. P.S. I originally subscribed to thelist using the wrong email address, but that has been corrected.
