D2r handle closer

d2r-handle-closer.ps1 closes "Check For Other Instance" handles from d2r.exe processes. After starting the script it says running checking/closing handles every 10 seconds.

Handle.exe is required for the script to run and must be downloaded from Microsoft/extracted to the same folder as d2r-handle-closer.ps1.

How it works

The script runs in a loop (every 10 seconds) and scans for d2r instances with open "Check For Other Instances" handles.

The command to find the open handles using handle.exe is:

> .\handle.exe -a -p d2r "Check For Other Instances" -nobanner
D2R.exe            pid: 110040 type: Event          7E8: \Sessions\1\BaseNamedObjects\DiabloII Check For Other Instances

You can then use handle.exe along with the pid and event from the prior call to close the handle:

> .\handle.exe -c 7E8 -p 110040 -y -nobanner
  7E8: Event         \Sessions\1\BaseNamedObjects\DiabloII Check For Other Instances

Handle closed.

When an open handle is found the script uses RegEx to pull the pid/event out of the serach result and then passes them into the close handle call.

How to run

Download d2r-handle-closer.ps1/Handle.exe/pwsh and put them in the same folder. Run an administrative PowerShell 7 prompt and navigate to the folder where the files are (ex: cd D:\src\d2r-handle-closer).

You might have to run Unblock-File .\d2r-handle-closer.ps1 before your PC will allow you to run it (only needs to be done once). You will also have to run Set-ExecutionPolicy -Scope CurrentUser RemoteSigned if this is the first time you are running PowerShell Scritps. You can read more about Executionpolicy from Microsoft here.

Then just run the script Ex:

PS D:\src\d2r-handle-closer> .\d2r-handle-closer.ps1
  794: Event         \Sessions\1\BaseNamedObjects\DiabloII Check For Other Instances

Handle closed.
@{Path=D:\Games\Battle.net\Diablo II Resurrected - 1\D2R.exe}
  79C: Event         \Sessions\1\BaseNamedObjects\DiabloII Check For Other Instances

Handle closed.
@{Path=D:\Games\Battle.net\Diablo II Resurrected - 1\D2R.exe}
@{Path=D:\Games\Battle.net\Diablo II Resurrected - 2\D2R.exe}
  7A0: Event         \Sessions\1\BaseNamedObjects\DiabloII Check For Other Instances

Handle closed.
@{Path=D:\Games\Battle.net\Diablo II Resurrected - 1\D2R.exe}
@{Path=D:\Games\Battle.net\Diablo II Resurrected - 2\D2R.exe}
@{Path=D:\Games\Battle.net\Diablo II Resurrected - 3\D2R.exe}

To stop press Ctrl + c or close PowerShell.
