Amen. Managed to ‘prove’ I was competent enough to run linux on my personal laptop due to a combination of needing me as an employee and that I was able to show why their RDS solution broke after an official windows update with xfreerdp.
I keep my windows workstation up to date and switched on - but all work is done from my laptop and no one’s questioned me so far.
Strictly according to the IT policy, Windows is not required - they just thought I wouldn’t be able to access anything without it. When I proved to the auditors that I met every checkbox on the requirements list, they said it was fine too xD
I would trade meticulous handover notes fit in to the working week if it meant I could work one week on, one week off.
