[Windows 10] After startup CPU and I/O gets hogged

If the culprit for this is WUDFHost.exe or something like that, I actually have not found a solution so far. Apparently, it has to do with media library synchronisation when you plugin a portable device.

• Some mention you should just disable this device in the device manager, but it did not help with me. At least the device stayed usable.
• Killing the process is cumbersome. First of all, you need to have admin role to do so. Apparently people suggesting the kill, do not restrict their usual user with removing that role. But much more important, the WUDFHost process started again immediately after the kill.
• Rename the WUDFHost.exe (alternatively remove it), but as it is owned by "Trusted Installer" it is a bit tedious and in my case did not help. Maybe after a reboot, things look brighter. However, to do as mentioned:
1. Get admin rights and change the owner of the file (C:\Windows\system32\WUDFHost.exe) best to Administrator.
2. Rename the file with admin rights.
