When I restart the computer after selecting to enable memory integrity, a BSOD is shown saying there is a problem with the hswultpep.sys driver. Diagnostics are run and the computer restarts correctly but memory integrity is not enabled. What is the solution?

    hswultpep.sys

    is associated with Intel Core 4xxxU and 4xxxY Processor Line Power Engine Plug-in Driver.

    It is located at :

    Visit Intel's support site and download the driver.

    Hi. Thank you for your question and reaching out. I’d be more than happy to help you with your query.

    I have linked an article below that may help solve your issue. Here is what the article has to say:

    According to Colif, the Windows 11 installation media (ISO or USB) needs to be the same edition, version, and build number as the Windows 11 that is already installed.
