I am having problems with Parallels 11 with Windows 10 on both my iMac and MBP. First I updated my Parallels 10 to 11 on both machines and after that I upgraded Windows 7 to Windows 10 on my iMac and did a fresh Windows 10 install on the MBP. Both systems have in generally problems with the start menu, task bar (and some system programs). Every time you go to the start button you get the timer and after clicking some times on it is looks like the start menu / task bar is restarting itself because it doesn't respond. It is very irritating and because it happens on both my Mac's I think it is a more common Parallels issue. Just to be sure I also installed a fresh copy of Windows 10 on my iMac and again the same thing happens. I found some information about parallels 10 with DirectX settings but disabling that didn't solve the problem. I ma running Windows in normal Window mode (so no Coherence or Modality) Other question is how to turn of that irritating power save/resuming mode on the iMac.
Some info:
MBP 13" Retina Early 2015 (8GB / SSD)
iMac 21" mid 2011 (16GB / SSD)
Parallels 11 Pro
Windows 10 Enterprise 64 bit
