Working at a customer (you know who you are) I asked

– How do you update all PXE\WDS servers around the globe?

– We logon and update them

– Would you like to have script that does that?

– Yes

So, here it is:

$Servers = "server1","Server2","Server3","Server4"
Foreach($Server in $Servers){
    wdsutil.exe /Verbose /Progress /Replace-Image /Image:"Lite Touch Windows PE (x86)" /Server:$Server /ImageType:Boot /Architecture:x86 /ReplacementImage /ImageFile:"D:\MDTProduction\Boot\LiteTouchPE_x86.wim" 
    wdsutil.exe /Verbose /Progress /Replace-Image /Image:"Lite Touch Windows PE (x64)" /Server:$Server /ImageType:Boot /Architecture:x64 /ReplacementImage /ImageFile:"D:\MDTProduction\Boot\LiteTouchPE_x64.wim" 
}
