Fixing 'MMC cannot open the file...' error

When you try to open any .msc file you get an error similar to the screenshot below.

Error dialog you get when you try to open any .msc file

This happens when there's a registration corruption with msxml3.dll. To fix, just run the following:

regsvr32 msxml3.dll

and you should be able to open Microsoft Managment Console again.
