At some point I got sick of burning coasters and switched to doing Windows trial installs from USB by using the Windows USB/DVD download tool to “burn” ISOs to bootable flash media. I quickly realized that USB sticks were error-prone, but SD and Micro-SD cards have some magic error correction that makes them reliable. The big problem is, they don’t take a label. And there’s no easy way to tell by looking at the root what version of Windows it is. Sometimes even running the installer doesn’t tell you immediately. I should stick a readme file in there, but I don’t.
Fortunately, there is a way to tell exactly what installer it is. From an administrative command prompt, you run this command against the drive letter where the SD card mounted:
And you get something like…
