How to Fix ‘MRT blocked by System Administrator’ Issue in Windows 11/10 – Guide
I have been using the Malicious Removal Tool (MRT) for a while now and I have to say that it is a great application. It helps in fighting malware and offers other PC protection when the computer is scanned by MRI from time to time. However, I have had some problems with it recently. For some time while using the MRT, I got an error message, “MRT blocked by system administrator. Contact your system administrator for more information.” This error message only indicates that the application has been blocked by the administrator. However, it is very annoying when software developed by Microsoft doesn’t work properly on Windows operating system. It’s amazing to see that software developed by Microsoft doesn’t work properly on its own operating system.
There are some methods that can be used to resolve this issue, which have been very well received by users and we’ve put them together in an article for you to check out! The software may be listed in the software restriction policy, which automatically generates the error message each time it runs. Certain registry entries may prevent the tool from starting and your best bet is to try to delete them. The file may not belong to the administrator account and you should try to change ownership to take this into account. The file sometimes requires administrator rights to function correctly.
Fix: MRT blocked by system administrator
Remove MRT from the list of programs restricted by software policy
The application MRT has been blocked by the system administrator. This is likely because there is a policy that designates MRT as a program to be prevented from running.

This value should have a data type of DWORD (32-bit). Change its value to 0xFFFFFFFF.
