Took the steps you said. When it automatically rebooted after the first step, it started up to the desktop much faster, and the desktop was faster, too but started up a little differently than it used to, as in it took longer for my start bar/etc to come up. Just a wallpaper-less screen for a while. Definitely an improvement though. No abnormal lag when I started trying to do things.

I didn’t reboot after I did the last part with JRT, should I?
