Running any kind of tweaking suite or optimizer will almost always ruin Win7. It needs no tweaking beyond normal system settings, and only its onboard tools with a free lightweight AV and the Win7 Firewall for best performance.
Factory Recovery is larded with preinstalled crapware and useless OEM utilities which have much better versions built into Win7. These throttle the OS and are corruption themselves. Almost no tech enthusiast would run such an install but instead will Clean Reinstall - Factory OEM Windows 7.
Focus on the steps in the blue link to get a perfect install and then don't tweak it beyond normal system settings, and only use the few tools and methods recommended to maintain it. A perfect reinstall will yield only instantaneous performance or else you need to upgrade hardware.
