Hyper-v fail to start any virtual machine - an invalid Handler was specified

After the last anniversary update of windows 10 (of august 2) hyper-v fail to start any of the virtual machine, new or old.

The message I get is "Virtual Machine Name" failed to start worker process: An invalid HANDLE was specifies (0xC0000008).

I have try many thinks, and look all over the inteet bug I can not find solution.

1. I have totally remove and re-install the hyper-v
2. I have check for correct permissions on the directories of the vm
3. I have run Process Monitor to see why is crash
4. I have read the debug report that send to MS
5. I have made from scratch new test virtual machines, for both generations.

after all that is still not runs...

Any idea is appreciate.
