Pass parameters to program started with Runas
Solution 1
The correct syntax is to include both the target executable and its parameters in double quotes like this:
runas.exe /user:domain\username "perfmon.exe /res"
runas.exe /user:domain\username "perfmon.exe \"argument with spaces\" /res"
More Information: Runas command
Solution 2
For anyone stumbling upon this while searching for a way to use runas
with an application where its own parameters may contain spaces.
The original accepted answer with \"
did not work for me.
What works is to put a double quote to actually be able to pass arguments with spaces:
runas.exe /user:domain\username "perfmon.exe ""argument with spaces"" /res"
It is actually explained quite nicely here: https://ss64.com/nt/syntax-esc.html

I am trying to start Performance monitor as different user. I found
runas.exe
but syntax for program arguments makes me go crazy. The following syntax works:C:\Windows\System32\runas.exe /user:domain\username perfmon.exe
But since
perfmon.exe
has the argument*/res*
the following line doesn't work:C:\Windows\System32\runas.exe /user:domain\username perfmon.exe /res
I tried to escape
*/res*
but without any success. I tried:"/res" \"/res\"" \"\/res\""
Any ideas?
