StdoutRead gpupdate /force

Recommended Posts

StdoutRead isn't working when I use gpupdate /force (Windows 7 Professional/Enterprise). It's working fine with other switches, e.g. gpudpate /target:computer, but once /force is introduced I get nothing back.

#include <Constants.au3>

$time = 0

; These don't work
; $sCMD = 'c:\windows\System32\gpupdate.exe /force'
$sCMD = 'c:\windows\System32\gpupdate.exe /force /target:computer '

; These do work
; $sCMD = 'c:\windows\System32\gpupdate.exe /target:computer '
; $sCMD = 'c:\windows\System32\ipconfig.exe /all'

Local       $sTMP = ''
Local       $sSTD = ''

Local Const $iPID = Run($sCMD, 'c:\', @SW_HIDE, $STDERR_MERGED)

While 1 = 1

    $sTMP = StdoutRead($iPID, False, False)
    $time = $time +250
    If @error Then

        ExitLoop

    ElseIf $time > 60000 Then

        ConsoleWrite("timeout: exit loop")
        ExitLoop

    Else

        $sSTD &= $sTMP
        ConsoleWrite($sTMP)
        Sleep(250)

    EndIf

WEnd

ConsoleWrite($sSTD)

I'm just getting timeout: exit loop.

For those familiar with gpupdate /force, I'm looking for the OK to Restart?. (Y/N) line so I can notify users they should restart, typically for software updates.

I'm hoping someone has come across this before! I'm getting the same behaviour on a few computers.

What do you get if you run the command in the command window manually on the same computers?


If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

It's working as expected there, immediately the line Updating Policy... appears, then after a while all this will be printed:

Updating Policy...

User Policy update has completed successfully.

The following warnings were encountered during user policy processing:

The Group Policy Client Side Extension Folder Redirection was unable to apply on
e or more settings because the changes must be processed before system startup o
r user logon. The system will wait for Group Policy processing to finish complet
ely before the next startup or logon for this user, and this may result in slow
startup and boot performance.
Computer Policy update has completed successfully.

The following warnings were encountered during computer policy processing:

The Group Policy Client Side Extension Software Installation was unable to apply
 one or more settings because the changes must be processed before system startu
p or user logon. The system will wait for Group Policy processing to finish comp
letely before the next startup or logon for this user, and this may result in sl
ow startup and boot performance.

For more detailed information, review the event log or run GPRESULT /H GPReport.
html from the command line to access information about Group Policy results.

Certain User policies are enabled that can only run during logon.
Certain Computer policies are enabled that can only run during startup.

OK to Restart?. (Y/N)

What's different with the two working examples above is with /force it doesn't close the window after. But I would expect the ConsoleWrite($sTMP) in the loop to still work. I've tried using ProcessClose where my timeout is but it didn't help.
