Not to be confused with the run as administrator option, trying to run file explorer using different credentials. I have seen several posts with this issue, but now real solutions. I am using:
C:\Windows\System32\runas.exe /netonly /user:<Username> "C:\Windows\explorer.exe"
does not work. (does work for all other EXE's and MSC's)
I did see one post where someone recommended launching a cmd window as administrator, and a runas and the launching explorer.exe from there. However, that still does not seem to use the credentials specified.
