Yes, I've googled. Many, many times over the past year.
I am constantly running into issues trying to delete files--mostly .exes. It really interferes with many "autoupdate" programs like Steam and Origin. I have to use safemode to install updates... It also affects other things like compiling; I get occasional (essentially random) errors when the output file already exists and I want to overwrite it. I also can't delete the affected file(s) for a long time--often upwards of 1 minute. However, if I wait long enough, I can eventually delete the files.
The error is always something like "you don't have permission blahblah." I have tried those unlocker programs, and while they can sometimes delete the file, an autoupdater (for example) can never actually write the new copy, even though I don't see the file in the directory.
I have tried running programs as administrator.
I am using an administrator account.
I have UAC disabled.
I am not running an antivirus or any program that should be interfering.
I've tried changing folder permissions as per multiple guides I have read (some from this site).
None of the above does anything..
This problem has been plaguing me for almost 1 year. I have reinstalled Windows 7 twice in that time, and the problem exists from the get go. I have been using Windows 7 for over 2 years, but I never had this problem until my second to last installation. I don't know what changed.
