If anyone can help me figure this out I'd REALLY appreciate it! OK here's my story: I had XP installed with Service Pack 1, and patched it with the PatchXP.exe file that I downloaded here. Everything worked fine and I changed my theme at will. Then I had a PC problem and had to repair my XP installation. After repairing the installation, I installed Service Pack 1 again. Then I downloaded all other updates etc and got everything just about back to normal. Then I ran PatchXP, and it refused to work for some reason! No matter how many times I run it, unpatch, patch, reboot, nothing seems to work. I installed that program "StyleXP" and that did work, but I don't want some extra unnecessary program running just to replace uxtheme.dll.. Plus I'd have to eventually pay for StyleXP, right? So while StyleXP was installed, I made a copy of the uxtheme.dll file, assuming it was patched. Then I removed Style XP, and renamed the "patched" uxtheme.dll file to be the main uxtheme. Then rebooted, and XP still won't allow me to change my theme Can anyone help? Also, for the record, if I go to display properties and then click the Appearance tab, it takes a REALLY long time to show up. As in like, 30 seconds, as opposed to 1 second. Its been like that ever since this whole mess began, after repairing the XP install. Thanks in advance for any solutions I get!
