Hi, Thank you very much for this tool. It's invaluable. Without it, Vista was unusable for me, even on a Core2 Duo system. However, I can't shake this Wim Filter manager error on XP. I dual boot and on Vista, vlite installed the filter manager without problems and works flawlessly. On XP, whenever I click on "Vista Ultimate" in the choice box, I get the infamous filter error recommending me to restart the computer. I restart, but it doesn't solve my problem. I tried everything. I get the feeling that if I could uninstall the filter and reinstall, this could solve it, but I haven't found a way to uninstall it once installed. I searched the forum and the best recommendation is "restart the system and try again", but it doesn't work. Any other ideas please? Or is there an alternative way like using DeamonTools?
