Reinstalling Windows
Windows restore points, hidden files, cached files, etc., are a few of the common things that fill up your OS drive unnecessarily. While its time consuming to fix these issues, it can be done relatively easily. However, there will be times when your hard drive keeps filling up without any logical reason. If you're facing one of those issues, it might be time for a fresh reinstall. Grab the nearest copy of Windows and give it a quick install. It'll fix all your space-related issues.
Uninstall or Move Unnecessary Apps
A lot of times, we install some software on our PC and completely forget about its existence later on. These one-time softwares worth 200MB-300MB might not seem like a lot. But they start adding up pretty quickly. Go ahead and take a quick glance at your installed programs. You can do this by going to Control Panel > Programs > Programs and Features on Windows 10 and uninstall any programs that you don't need. Depending on your usage, you'll probably be able to free up quite a bit of space this way.
Using CCleaner
CCleaner is a free-to-use desktop application that's extremely useful for cleaning up space on your PC. It also has a premium version of the app, but the free version will work just fine for what we plan to do. CCleaner looks for temporary files stored in various places on your computer. These temporary files can be backup or unsaved documents and images from applications like Microsoft Word, Adobe Photoshop, etc. It can even wipe the cache of your browser to free up several GBs worth of space. It's a great way to free up space, especially if you're using an SSD.
