User:Mjb/Setting application compatibility mode

You can set application compatibility mode for multiple files at once.

To set Windows XP Service Pack 3 mode for all .exe files in a folder:

for %x in ("*.exe") do reg.exe Add "HKCU\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers" /v "%~fx" /d "WINXPSP3"

If you want it to be for all users, use HKLM instead of HKCU. If you do that, though, you won't be able to change it in the file Properties > Compatibility dialog.

The /d value is a space-separated list of values. The first value must be one of:

• WIN95
• WIN98
• WIN4SP5
• WIN2000
• WINXPSP2
• WINXPSP3
• VISTARTM
• VISTASP1
• VISTASP2
• WIN7RTM
• WINSRV03SP1
• WINSRV08SP1

The rest are optional:

• 256COLOR
• 640X480
• DISABLETHEMES
• DISABLEDWM
• HIGHDPIAWARE
• RUNASADMIN

To unset:

for %x in ("*.exe") do reg.exe Delete "HKCU\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers" /v "%~fx" /f

Leave off the /f if you want to be prompted for confirmation every time.
