If you do not log on 15 minutes after the system starts, Win2000 will start the screen saver.
Logon. scr is located under c: \ winnt \ system32. A Win2000 flag will run on full screen.

So I first renamed logon. scr to logon. zqs, and then
Copy assumer.exe to c: \ winnt \ system32 and change it to logon. scr.
We need to remove the hard disk to another machine. Of course there are other methods.
Restart the machine. After the logon dialog box appears, do not log on. Wait for 15 minutes.
When the Protection Program is started, a resource manager appears and the target is located under c: \.
