Note: I do not offer any support for this. If this did not work for you, either:
- You cannot follow instructions correctly, or
- You cannot use more than 4GB of physical memory on 32-bit Windows due to hardware/software conflicts.
To remove the patch:
- Run msconfig, click Boot, highlight the entry named “Windows 7 (PAE Patched)”, and click Delete.
