I've found that my biggest problems with this migration to W11 has been that they forced me not to use a local account at the same time. Connecting to drives etc takes ages now whereas I used to save on the machine and then back up to a network drive periodically. I am not often on site at work which doesnt help as it all works faster when you are on the work network.Windows 11 genuinely is terrible, we have to use it at work due to diagnostic programs and it's bloody awful compared to Windows 10..
A real step back imho (I have been using it for a good couple of years now and it doesn't age well).
They are going all in to ban and disable Local Accounts too..
I still have a local admin account as need it for some programs I use so I may switch to just using that but recognise the security concerns so have resisted so far.
W11 itself hasnt been awful - I have made it look like 10 so appearance wise not a lot has changed.
