Hyper-V is pretty good, but it does have some functional limitations that are annoying. One I found was the inability to display the guest VM's desktop full-screen extended across 2 of my 3 monitors (one is the laptop, the other two are externals). It will do one, or all, but not "some". I suspect it's actually a limitation in the Hyper-V RDP interface to the VM.
Good luck tonight with your work. Sounds like fun! :-)
The Ubuntu installation did not mess up my Windows installation, but it in order to get into Ubuntu I have to do an advanced restart in Windows 11 and select it as the boot device from there... I am sure that I will be able to get it to work normally in the morning.
And I do find this type of troubleshooting exercise entertaining because I am a weirdo, I think.
