Windows 10, Parallel 10: CPU overused

    Hello all

    I've upgraded from windows 7 to windows 10 (had some sharing directories problems, solved thanks to the forum :).
    The problem is that parallels takes a lot of CPU: typically 60% when doing "nothing" (the windows task manager announcing only 15% of cpu usage) and 127% when doing "things". I'm pretty sure it was not the case with windows 7. I've seen that CPU usage display may be different (because of multicore) but now the macbook often overheat, it was not the case before.
    Do you think it's normal ? Should I upgrade to parallel 11 (would be a bit disappointing to be obliged to do that)?
    Or would there be some configuration fixes? I've had a look at the web and the forum but with no success.

    Thanks in advance

    Vigouroux, I had the exact same issue and I went through all the KBs on performance, following each step with no success. I almost gave up and went back to VMWare, but then Yosemite 10.5 came out and at the same time there was an update to PD Version 10.2.2 (29105), and a bunch of Windows 10 updates to the system and to Office. Now all is well - very strange! My performance on all machines now looks like the attached, which is perfectly acceptable. It is not clear to me which update fixed things, but one - or a combination of all - did. I've filed this as an X-File (unexplained), and now just have my fingers crossed the problem does not return.
