Memory Integrity

ricorocks · Jul 7, 2023

A Win11 KB update gave 'Mem Integrity 'off'

1. Tried to turn 'on' <error see incompatible drivers>

2. Incompat found 'Corel PxHIpa64.sys'

3. Terminal Mode admin. del > lower key at :

"Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4d36e965-e325-11ce-bfc1-08002be10318}

Look for a LowerFilters key with the value of PxHlpa64.

Either modify that name/value pair or delete it.

Reboot."

4. At that exact path, deleted 'lower key' PxHIpa64.sys <<<<deleted>>>> note this driver used for 'cd's' line Roxio & Sonic, perhaps others

5. Reboot try turning on mem integ. error PxHIpa64.sys still found

6. regedit using power shell admin. Search entire reg PxHIpa64.sys not found. <<<<however the key is still present, minus lower filters PxHIpa64.sys.

I suggest removing the driver using Device Manager. See the link below for details.

@Sir_George - Thank You for the quick reply!

That with the reg edit to the driver gone, windows still say the driver at: c:\windows\drivers

del PxHIpa64.sys > turn on 'mem integ' > reboot ALL GOOD!
