10. Speccy

Maybe you’ve forgotten what kind of RAM you bought, or want a quick glance at your CPU’s temperature. Speccy scans your machine and gives you a complete rundown of everything, from model numbers to temperatures, fan speeds, S.M.A.R.T. status, and…well, pretty much anything else you can think of. It’s also available in portable form, so you don’t have to install anything—just stick it in a folder for when you really need it. For an alternative, check out HWiNFO.

9. Ultimate Windows Tweaker

When you first install Windows, you probably get everything set up just the way you like it, including all your favorite little Registry hacks and unsupported tweaks. You might even discover new ones later and try them out. Apps like Ultimate Windows Tweaker make this a lot easier, and they’re useful to keep around later if you start incorporating new things into your workflow. Its list of features is endless, allowing you to tweak the tiniest features in the taskbar, Windows Explorer, the lock screen, and anything else you could imagine. Download it once and keep it forever (and as always, back up before you start tweaking your system).
