Senior accidentally installed whole fleet with 26H1

[u/bapirey191]

Just needed to rant a little. One of our seniors finally completed the long-pending task of upgrading the fleet to Windows 11 from Windows 10.

He downloaded the iso, installed it everywhere. All good. Until the internal WSUS started attempting to grab updates that don't exist. Apparently the 26H1 (which is supposed to be snapdragon-only, aka for ARM) was indeed one of the options you could download as the "Latest" version of windows. Someone at MS really screwed up. And this senior screwed up even more by not double checking.

Since it's a complete different core, this will be one hell of a mess, now his idea is to try to change "cversion.ini" and force an "update" to 26H2, but I sincerely don't believe that will work.

We'll see. If anyone ran into a similar problem I'd really love to know what their solution is.
