    Bombs and restarts a few times per day. Caught a slight glimpse of the quick blue screen,something like "thread exception not handled", then goes blue, to repair screen, and reboot. Happened in 24H2, so I upgraded to 25H2. Same problem.

    The issue was resolved by uninstalling Norton 360 from the host

    I use Norton 360 as well. I worked around the issue by installing the previous version of Parallels (v. 20), but I won't be able to update macOS. Does anyone know if a fix will be provided for this incompatibility between Parallels v. 26 and Norton 360?

    Same problem here. I installed 25H2 today, and after the Parallels Tools were installed it continually locks up on the RESTARTING screen. Not good.

    My problem with 25H2 seems to be sorted out now. Don't know what I did to get it working again, but it's working.

    Are u sure it's resolved? Coz me running Parallels 26.1.1 got 3 BSODs in 3 minutes. Then it may work for hours, sometimes days, but then suddenly BSOD. I tested memory for errors with Windows standard memory check tool from control panel, it gives 0 errors. But BSOD says(minidump opened in WinDbg): "
    Probably caused by : hardware_ram ( PAGE_NOT_ZERO )
    Followup: MachineOwner
    ---------
    *** Memory manager detected 49449(<-this number is always >40000 but changes every time) instance(s) of page corruption, target is likely to have memory corruption."
    But I never had these before upgrading to Parallels 26.0. Changelog says they fixed something about Norton 360, but I don't have it. I have Crowdstrike and Symantec Endpoint Protection installed. I cannot uninstall these, coz it's not my personal PC. I recently upgraded to Windows 11 25H2 (coz 24H2 upgrade via Windows Update failed with the same BSOD...). On Windows 10 there were less BSOD like this, but I think I got some. How to fix?

    my BSOD error is :
    CRITICAL_STRUCTURE_CORRUPTION 0x109
    (every time same error)
    btw host OS now is macOS 15.7.1 works super stable, not a single crash in years of use. hardware is mac Mini 2018 (Intel based)

    Hi, I'm not having any BSOD problems. I have two Windows 25H2 VM's - one for games and one for productivity. Both are working fine with no BSOD's. I'm not sure what your problem is. My issue was caused by the installation of Parallels Tools AFTER the update to 25H2, not the actual install of 25H2 itself. That was working. My problem happened only on one of the VM's and it happened only after I tried to install Parallels Tools after the 25H2 installed. I hope you get your issue resolved.

    ...after using it for a while I doesn't BSOD any more (for now). When it failed with BSOD yesterday for first time I wasn't even using it - maybe some background process caused BSOD, I checked Event Logs, and not sure but maybe it's a Symantec Endpoint Protection (installed inside VM) weekly scan which caused system crash after it started. Are we need additional fix for it like for Norton 360 or it's a different problem?
