Windows forced the install of KB033375. Win 11 Pro
Started off system rebooting and being really slow. Eventually came up and system was super slow. Indicators online said something about turning on memory integrity - so first quest... Remove Roxio and pinnacle products. Had to delete PxHLpa64.sys to get memory integrity to turn on. Rebooted - still slow. Removed anti-virus - still slow. Removed programs from loading in startup - still slow.
Have seen suggestions on removing kb033375 - can't uninstall. Windows seems to have locked it up from removal.
HP diagnostics ran fine. Any suggestions?

I see that you are facing a slow performance issue with your Laptop.
Please follow the steps below to perform an extensive system test to confirm if the hardware is working fine.
1) Shut down the computer.
2) Turn the computer back on again and repeatedly tap on the ESC until a Startup menu appears.

If the hardware is working fine. Kindly refer to the steps on this link to update the BIOS and let me know if that resolves the issue.
Make sure you keep only the charger plugged in while updating the BIOS for your PC.
