Dear Community, it's quite some time since the last post, and I have been continuously working on my new Vista x64 Sp2 installation since three weeks now. Yesterday, my system was finally finished. I had no luck, and MagicAndre1981 was right: Windows Media Player had to be removed. I experimented a lot with other removals and kept a lot of files in the "keep"-list of vLite (see new last session.ini). But always, the "Turn Windows-Features on or off" problem remained. Finally, I removed Windows Media Player, and it suddenly it worked. I do with vLite a long time, and never kept Windows Media Player with vLite, and Turn Windows-Features on or off" was always working. I think the dependency comes new with Vista Sp2. I will not work with vLite again, it's getting old and not suitful for Sp2 and above systems. By the end of the year, I plan to switch to Windows 7, too bad there is no real software for it like nLite and vLite was for XP and Vista. I am not an expert, and I will have to leave the install default. When you look at my last session.ini, you see I have (after a lot of struggeling and failures) only three components removed - Media Center, Screensavers, and Zip Folder. It's no loan to work this way, my earlier systems had far more removed and worked without any (known or felt) issue. Anyway, thanks a lot for helping me in this time- and nerveconsuming case!
