Just used this to change Kernel-MaxPhysicalPage and Kernel-WindowsMaxMemAllowedx86, so that W10 22H2 x86 could use all my 8GB of ram. Wonderful (also thanks Geoff Chappell). The only flaw is that the disable sppsvc button doesn't seem to work, and I had first to manually set start=4 to it in HKLM\SYSTEM\CurrentControlSet\Services.
