I have been using Windows 7 for about 6 years and never seen anything like this before. It looks like something had messed up security on my computer. I suspect it could be either a recent Windows update, or an antivirus, or AdobeARM (already removed). It looks like my administrator's rights had suddenly become limited.
I am a single owner of a desktop computer that runs Windows 7 Home Premium with SP1. It also has COMODO Firewall with HIPS, Avast Free Antivirus and Malwarebytes 3 (the latter two have real-time protection off). Antivirus scans report no threats found. According to the OS I am an administrator on the computer. Now just one of the weird things as an example: I have installed a program Foxit Reader, and it created a shortcut on the desktop. I can not rename this shortcut - when I try, I first get a message: "You'll need to provide administrator permission to rename this file".
After this, clicking "Try Again" just keeps producing the same message.
I have already found a number of workarounds for this particular manifestation of the problem:
1) I can copy the shortcut to another folder, rename it in that folder and then copy it back on the desktop.
2) I can boot Windows into the Safe mode and in that mode I can rename the shortcut right on the desktop.
3) I have created Administrator account on the computer and when I logon into that account I do not get security restrictions, can rename whatever I want and open any folder, without any "Access denied" messages.
What I am interested in right now is not a workaround (because this is by far not the only "Access denied" restriction that I presently keep getting), but a solution how to reset my administrator's rights so that the system stop giving me "Access denied" messages.
How can I reset full administrator's rights for my account?
I want to emphasize again: I am not looking for a solution to rename the shortcut. I want to get rid of the "Access denied" restrictions in my account. I do not get such restrictions from the other Administrator account. As to this particular the file permissions:
I just renamed my account from "User" to "SuperUser". It turned out, when it comes to file permissions, the system does not regard me as an administrator: And this is how it looks from the other "Administrator" account:
So it seems like an unknown program (most likely AdobeARM) had changed my account type from "Administrator" to "User", but the change is made only in one certain place, so that the "Control Panel" still regards me as an Administrator. How can I undo that change?
