Almost 10 minutes I will never get back
Yesterday my morning started with a little green icon in the system tray of my Windows 10 workstation. It was time to reboot to install mandatory (already provided) updates. Managed workstations are fine and I am not one to complain, but I am used to the luxury of Linux. There you just install updates and if you really want (and do not use kexec) you can reboot to activate a newly installed kernel. This keeps productivity at a maximum.
To make a long story short, I almost had to wait 10 minutes for the updates to install and was not able to get any work done. Some black magic happened at shutdown and some at startup and this is considered normal. Ignorance is bliss.
