A few weeks ago my vista aero was missing this is my last resort to get it back i will list a number of things i have tried. My only options under the color and appearance are. Windows standard, windows classic, and a few high contrast ones. When i try to change to the aero theme i get an error that says "the theme could not load. the volume for a file has been externally altered so that the opened file is no longer valid. File C:\Windows\resources\themes\aero.theme" I have run virus scans with eset smart security 4.0, super anti-spyware and malware bytes. The only virus that picked up was with malware bytes and is was reset.exe i believe. I downloaded another aero theme files from a reputable source and it wont let me overwrite the file even with admin privilages. I installed vista glazz and it says my msstyle file is invalid. when i click on the windows folder and the resources folder they checked read-only. so i tried unchecking all the folders, again even with admin wouldnt let me. so i ran an sfc /scannow and it came up with this(attached file).
Please someone help with this if i have to reinstall windows i will but i would really not have to if i could. Please no posts about why use aero just uses up resources. I like the way it looks
