Keeping Windows 7 running smoothly?

Disable useless garbage like visual effects and services (Black Viper is a good place to start),

Defrag on a schedule.

Do not use ****ty "tweak" tools like Tune-Up, Simple Performance Boost, etc.

Do use Revo Uninstaller if you want to remove stuff, because it nukes any trace of what you're removing (leaving everything else alone).

Use something like CCleaner to remove junk like cookies, temp files and so on.
