I've loaded multiple different versions of Windows 11 Pro on modern hardware (Z590 mainboard, DDR4 RAM, etc.). Each install was clean (I wiped the boot SSD each time). I was able to successfully load the OS each time, but I am unable to execute any .exe, .cmd, or .ps1 files, programs, or scripts. I get an error stating that there is no associated program available.
I've used only clean ISOs downloaded from UUPDump, and even one from MS MDT. All have June 2026 updates. I use a small autounattend.xml to create a local user account, with nothing else added or removed. It is very generic. I have not tried older ISOs yet, but I may when I have time.
Does anyone have any clues? I'm at the frustrated, pulling-my-hair-out stage.
TIA
