    Literally since yesterday, Windows 11 has started running impossibly slow. Unusable. Software is either hanging or crashing. Is there a known issue with the latest Parallels? Have any other users had this happen? Windows has 16GB RAM and 8 CPUs, so I don't see why performance should be a problem.

    Hello,
    Kindly proceed with the steps below:
    1. Reproduce the issue.
    2. Collect a technical report (click Parallels icon || > Help > Send technical data > check "Attach screenshots..." > press Send Report) and send the report's 9-digit ID
    Regards,

    Mine too. It was fine for all these years and with the latest update, it has become unfunctionally slow on my M2 Max Pro with 64 gigs. I've sent them the technical data. To no avail. Good luck. They have a problem and must know it. They are going to lose users. I am certainly thinking of asking for my money back on multiple subscriptions I have with them.

    I'm using Parallels on an M4 MacBook Air and not seeing a performance issue. Perhaps this is specific to the M4 Max Pro?
