Hi, I have encountered some trouble with my icons becoming generic. It started off with some icons turning generic, and then more and more over the past couple of days. When I try to change a icon, it says windows can't find a file in the %Systemroot%\installer folder. So I looked at the "Windows\Installer" folder (after turning on hidden/system files) and there was only one executable in it. I know that it should have a lot more files in it, but the total size of the folder is less than 1 MB. Unfortunately, my system restore doesn't go far back enough to restore everything.
As for changes to my computer, I did take ownership of the Windows folder a week or so ago to change explorer.exe and ExplorerFrame.dll (I followed some guide online). But I know I did not make any additional changes to the Windows folder.
