Personally I test a lot of software, but for years I've been using Diskeeper and have never had a problem. I use the "Set It - Forget It" feature. It runs in the background without using a lot of system resources.

Sometimes when you uninstall programs, it could lead to your computer becoming slower thereby you should defrag frequently. Occassionally, you will have remnants of program files/shortcuts or folders left in your registry that the uninstallation program failed to delete. Therefore, you can buy a program to clean your registry and fix the problems. I bought one from the internet and it makes the computer run as new. If not for this registry cleaner, I would as in the past do a fresh installation of windows every six months or run an image backup. With a registry cleaner, I haven't done one for yonks.
Frequent installations and uninstallations do not harm the hard drive or computer system physically, however, after frequent uninstalls and installs, you might be left with a very big registry, which can increase the bootup time for Windows.
