Actually tested this, the answers check out. So all registry keys and all files on the desktop except for the .txt re removed when you go back to the restore point.

TESTERS...Make sure you test in a Workgroup not in a domain az joined evnironemnt. Like the question states it doesn't say its in a domain environment. Yes. I tested this to on a standalone windows 10 vm and Key 1 is still under HKEYCURRENTUSER. All the other keys have been removed. The txt file is still there and the other dll, sys, and exe were removed.

https://support.microsoft.com/en-us/windows/use-system-restore-a5ae3ed9-07c4-fd56-45ee-096777ecd14e As stated "Restoring won’t affect your personal files, but it will remove apps, drivers, and updates installed after the restore point was made." What all is considered as a personal file? "Personal files includes documents, photos and videos." https://answers.microsoft.com/en-us/windows/forum/all/what-files-are-considered-as-personal-files/6ed1964d-6ad1-424f-983c-0b76f0f76b66#:~:text=Personal%20files%20includes%20documents%2C%20photos%20and%20videos.%20If,your%20PC%20and%20keep%20your%20files%2C%20it%20will%3A

Only the recently installed programs and drivers can be uninstalled. Its task is to repair the Windows environment by reverting to the previous configuration that was saved in the restore point.

System Restore, by definition, will only restore your system files and settings. It has zero impact on any documents, pictures, videos, batch files, or other personal data stored on hard disks. You don’t have to worry about any potentially deleted file. It will also not affect the standard programs you have been using for a long time.
