Parallels Desktop 13.1 update causes 'Handle Not Found' in Windows 10 after Parallels Tools Install

I recently installed the 13.1 update (build 43108). When I bring up my Windows 10 VM, it 'auto installs' an update to Parallels Tools. When it is finished, it reboots, I get a Windows 'Handle Not Found' error. This is repeatable. I can restore my VM using Time Machine and the VM comes up, and I can log in without the 'Handle Not Found' error. Again, once I log in, Parallels Tools will 'Auto Install', and the cycle starts again.

I tried to temporarily solve this problem by disableing the auto install of Parallels Tools using this KB: http://kb.parallels.com/en/122947 This did not solve the problem.

I have now restored the Parrallels Desktop app itself. This also did not solve the issue.

Now I am restoring BOTH the Parrallels Desktop app AND the Windows 10 VM back to BEFORE the upgrade to 13.1. I will report back on the results of this test shortly.

This seem certain to me to be a parallels issue. The issue showed up after the upgrade to Parallels Desktop 13.1.

Please update your parallels tools install and release a fix/update ASAP.

Update: After restoring BOTH the VM and the Parallels Desktop Application back to 2 weeks ago resolved the issue. I will not be able to update to any future version of Parallels Tools until this issue is resolved by Parallels.

Hi @JohnL20, generally, the issue occurred due to the Windows update.

You can try the following steps to fix the issue:
  1. Login to Windows virtual machine.
  2. From Parallels Desktop toolbar choose Devices --> Keyboard --> Ctrl+Alt+Delete
  3. Go to Task Manager and Select File --> Run new task
  4. In the Run box type in " C:\Windows\system32\ctfmon.exe " and then click "OK".
