I came across this one a while back, and I had it again today. For those of you whom need to know how to run msconfig as an administrator when logged in as a standard user, this guide will help you. I’m pretty sure Windows Vista and higher can get around this with the UAC, as it will prompt the user for elevated privileges.
Example: “Hmm…how do I run msconfig as an administrator?”
Resolution: Press Start > Run and type in “CMD”. Hit enter and, once a Command Prompt window has opened, type the following:
runas /user:Administrator C:\WINDOWS\pchealth\helpctr\binaries\msconfig.exe
It will then prompt you for a password; don’t worry, no one can see this as nothing will show in the window while typing. It will now run msconfig as an administrator for you.
As pointed out in the comments section, some people seem to be having a little trouble getting this to work. If the above command does not work for you, try replacing “Administrator” with the username of your administrator account (your administrator account may not be called “Administrator”).
