I told you lots of times: you should run Windows XP with a limited account for your common tasks. However, sometimes you are such a lazy that don’t want to log into your machine administrator account to manage your computer.
Well, I am going to share a little trick I’ve been using for a long time: creating a root shell fast.
runas /user:mymachine\administrator /savecred "cmd /T:0C /K cls"
exit
P.S: Be careful when copying double quote marks.
Copy these commands and save them into a batch file name “root.bat” into your C:\Windows\System32 folder.
Each time you need a root shell, press Windows Key + R, write “root”, press Enter and voilà!
The first time you’ll be prompted for your administrator password. But next one, you’ll not.
PS: Now, you only have to drop files in the console (like *.msi, or *.lnk) to run them as administrator.
