Locked

Setting Extend my windows desktop onto this monitor without the GUI?

By jgrant_can ·
Hello, I hope someone can help. I've got 6 locked down and isolated environments of 150+ machines (XP Pro) furthest away is 24hrs. The users don't have access to the display settings through right clicking on the desktop or through the control panel. We have dual monitors connected to an ATI x1300 PCIe card and using the "Extend my windows desktop onto this monitor".

Every once in a while we receive a call saying the second monitor is no longer extended (normally cloning instead). Currently to fix this issue they call and I give a trusted user an account that has the appropriate permissions and then walk them through setting the Extend my desktop setting back and from there it works fine. I'm looking to automate this step hopefully as simply as possible.

Using a simply batch file I can open the Display settings panel using "%systemroot%\system32\control.exe desk.cpl,@0,3" however they still have to know to click on the second monitor and to select "Extend my desktop...". So ideally I'm looking for something that the users can click on without a GUI or other questions/interactions.

Any suggestions would be helpful. Thanks in advance.

Solution found unfortunatly with the gui no user interaction needed

by jgrant_can In reply to Setting Extend my windows ...

I've found a solution for our environment it's to use a VB script this will re-enable the extend desktop setting on demand.
Unfortunatly it uses the gui but no interaction from the user is needed.

FYI: I was able to get the extend desktop to turn off but not turn back on using the registry keys. I did a search and found 11 instances (found only 4 of the 11 with the key set to 1) of the ATTACH.TODesktop registry key.
example:
HKLM\SYSTEM\ControlSet001\Hardware Profiles\0001\System\CurrentControlSet\Control\VIDEO\{C3BFE9BD-.....}\0000 and then under \Mon10000080

--vbscript-------
Option Explicit
Dim WshShell, Dummy, Splash

On Error Resume Next

Set WshShell = WScript.CreateObject("WScript.Shell")

'Main
Call DoIt
WScript.Quit

Sub DoIt
wshshell.Run("%systemroot%\system32\control.exe desk.cpl,@0,3")

' Give Display Properties time to load
WScript.Sleep 1000
WshShell.SendKeys "2"
WScript.Sleep 10
WshShell.SendKeys "%E"
WScript.Sleep 500
WshShell.SendKeys "%A"
WshShell.SendKeys "{TAB}"
WshShell.SendKeys "{TAB}"
WshShell.SendKeys "{TAB}"
WshShell.SendKeys "{TAB}"
WshShell.SendKeys "{TAB}"
WshShell.SendKeys "{TAB}"
WshShell.SendKeys "{TAB}"
WshShell.SendKeys "{TAB}"
WshShell.SendKeys "{TAB}"
WshShell.SendKeys "{TAB}"
WshShell.SendKeys "{ENTER}"
End Sub 'DoIt
