Since Demember 2018, I have been experiencing long reboots and shutdown times. Alot of people have pointed out that the Realtek drivers might be to blame for this issue. Uninstalling the latest driver and using an older version does seem to “fix” the issue out (until Windows update decides to install the latest drivers again)
I decided to try my luck again and try and fix this problem, and I found the solution.
A newer Realtek driver was not available so I decided to update my Ryzen 5 Mobile Graphics drivers. The Graphics driver didn’t seem to fix the problem, so I tried and updated the Ryzen Mobile chipset drivers.
After a quick reboot, it seemed to have fixed the issue!
