Today, my Windows 10 got the Service Update to version 16299. After that, I noticed that my CMS tasks (the ones that were currently running, as well as completely new ones) stopped with "Postponed: Hypervisor failed to establish an online state in a timely manner" (of course, I had suspended the currently running CMS task and then closed down BOINC before the update started).
I then tried an ATLAS task, same error.
So I uninstalled VBox 5.1.22 and installed the latest Version, 5.2
After that, everything works well.
These "Service" Updates for Win10 use to do quite some harm to a current installation. Also, GPU tasks did not work any more (this was already the case with the previous Service update). So also this time, I had to reinstall the graphic driver.

Thanks for the tip.
For some reason, 5.1.22 did not recognize that 5.2 was available.
No problem here with the NVIDIA driver.
