Memory Integrity Protection question

Currently, I'm running Windows 11 on my old Dell 5490 laptop which was running Windows 10 and now I recently clean installed Windows 11 24H2 and running without any issues. Since it's an older laptop, the Memory Integrity protection was off by default after installation of Windows 11 and it was off the whole time when I was running Windows 10 on it.

I'm in the market of purchasing a Lenovo thinkpad t14 gen 5 in the future and my question is, if I download the needed drivers directly from Lenovo's website page, would the Memory Integrity allow it to install the Lenovo drivers or should I let Windows 11 just download all the needed drivers under the Windows Updates / Optional Updates and just let the Updates install the drivers from there?

I'm just afraid the Memory Integrity feature will block some drivers if I download them directly from the official Lenovo drivers web page.

The Memory Integrity feature defends your memory from malicious apps that try to exploit Windows drivers to take over your computer.

It will not block device driver update installation.

I believe that the Lenovo thinkpad t14 has this feature on by default anyways since it's a much newer model laptop.

So I shouldn't have any issues installing the drivers manually directly from Lenovo's website?

The Memory Integrity should not block them or report it as incompatible drivers?

Be aware that if Windows finds an "incompatible" driver it will turn Memory Integrity off automagically. I had the problem when I had an old Logitech joystick driver installed. Memory Integrity couldn't be enabled until I took it out.

God knows how MS decides what is an incompatible driver, so you may run into this problem no matter where you get the drivers from. It just depends on the driver, and it seems, its age.

The reason is MS has updated the standards for writing a device driver. Before Memory Integrity, manufacturers had more flexibility in making drivers.

To lock down Windows kernel memory (where device drivers run) from bad behavior, changes have to be made. Any driver which doesn't meet the updated standards is allowed to run, but Memory Integrity is disabled until there are no "out of spec" drivers. Windows has a way of determining which drivers meet that criteria.

A real problem is some manufacturers don't want to revise older drivers. It's not worth their time. If you're stuck with older HW, it's unlikely you will benefit from Memory Integrity since a compatible driver won't be written. Memory Integrity for the most part is a "nice to have" security feature.

The exception being if you have an app (or game) which requires it in order to run.
