I couldn't find a better solution online, but it affected the operation. I found the solution through my own investigation. Previously, I had been using win+R to enter "sysdm.cpl" to bring up the management interface.
Fault prompt:
In win10 system, this computer (My Computer) key management error reported, "C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Administrative Tools\Computer Management.lnk" cannot be found.
Error message: " This file does not have a program associated with it to perform this action. Please install a program, or, if a program is already installed, create an association in the Default Programs control panel. "
Essential reasons:
1. There is no corresponding program. 2. Incorrect connection. It can simply be thought that the connection method of this "Properties" button is wrong and cannot lead to the correct exe. Or the link method is gone.
Analysis and troubleshooting process:
There are two computers, one can be found and the other cannot. They all happen to be the same system. Therefore, go to the address that can be accessed normally through the fault path reported in the error. I found that it was actually a program under C:\windows\system32. This thing is actually a directory at the start menu--accessories--windows management tools level. I checked the same location on the faulty computer and found that the executable program existed. So there must be something wrong with the link in the end. System links must be configured in environment variables.
So I compared the environment variables in both computers. It was found that the windir item was not present in the problem computer.
Solution:
Win+R enter "sysdm.cpl" and click the Enter key. Enter the tin system properties interface, switch to Advanced--Environment Variables, select "New" in the system variables tab, the variable name is "windir", and the value is "C:\Windows".
Right-click My Computer and click "Manage" to use it. At this point, the problem is perfectly solved.
