Meddling with the internal structure of Windows is not the way to get the best performance from Windows. We see countless posts here from people who have done that, and have all kinds of problems as a result, not all of which are solvable.
Getting the best performance from your computer comes down to four steps.
1- Always start with a clean install.
2- Only install Windows on supported hardware.
3- Only install supported applications.
4- Run Windows the way it was designed to be operated.
