I've stuck solving the problem of multiple unknown devices in device manager. I've tried to follow this guide
but I cannot set permissions to be able to delete those keys in registry.
It wouldn't be a problem on my personal computer, but reinstalling third-person's laptop with huge ammount of specialized business apps is a hard way through pain.. It's like 3 days of hell.
Any help appreciated. EDIT:
Pasting two screens to better present the exact situation. The first one shows a list of unknown devices in device manager. The second one shows the regedit tool, and the problematic registry key branch. Yes, I know it is not the English language, but the screens are pretty obvious.
