For some tasks, you have to be in an elevated command prompt, if you’re lucky you get an error like “Access denied”, but sometimes whatever you are trying to do just doesn’t work.
It’s pretty easy to get an administrative command prompt, just click on the Windows Logo:
Type “cmd”, and the search results will open on the left hand screen, with “Command Prompt” listed. Right click on it. A menu pops up, choose “Run as Administrator”.
You’ll be prompted with the User Account Control confirmation. Click Yes.
Finally, the command prompt will open. You can always tell you’re in an administrative command prompt by the Title bar. If it says “Administrator” then that’s it.
