Page Table Entries (PTEs) may become depleted or fragmented on systems that perform a large number input/output (I/O) actions. When they become completely depleted the system may show a Stop error and halt. This tweak allows you to increase the number of PTEs available on the system.

Open your registry and find the key below.

Create a new DWORD value, or modify the existing value called 'SystemPages' using the settings below.

Exit your registry, you may need to restart or log out of Windows for the change to take effect.
