Access Denied (Windows System Error 5) on the registry keys and values.
Recently I came across a strange problem with the graphics card driver that it was manifested only under certain circumstances.
In short, the driver had to be replaced but the installation of the driver failed repeatedly.
After half a day of trying I understand that the problem was due to a registry key that the procedure on which the installation failed due to lack of access rights.
That is the ACCESS DENIED (Window system error number 5).
The driver now has been updated and the problem with the graphics disappeared but I wondered how many other similar situations (I mean access denied), there may be in the Windows registry?
So I set to work and I wrote the program RegError that scans the Windows registry to search for access denied errors.
You can find the RegError program from the single app Small Utilities download page.
