When I tried to open Device Manager or the Computer Management window, I received an error message: "MMC cannot open the file C:\WINDOWS\system32\devmgmt.msc" (2024)
When you tried to open Device Manager or the Computer Management window, you received an error message that resembles the following:
MMC cannot open the file C:\WINDOWS\system32\devmgmt.msc.
This may be because the file does not exist, is not the MMC console, or was created by a later version of MMC. This may also be because you do not have sufficient access rights to the file.
