Started my first job, it's a helpdesk. It looks that I get tickets and try to help people on the other side, have build some PCs and am at first week.

But after ~3 years of using almost exclusive FOSS, I found out corporate software (especially Windows!) to be so absolutely unbearable.

Having Windows as example, on the surface it is bearable, but as I need to do more advanced stuff, oh GOD!
I needed iperf3 to test LAN speed, traceroute to test why some device is not responding, rsync to copy files... But none of it is installed and installing every single program is super annoying and troublesome. After that I get countless update popups from all sides, ugh.
