1. Check Disk: This is a basic System Tool from Microsoft which is included in all versions of Windows. Right-click on the drive you want to check, click Properties and access the Tools submenu. Click 'Check now'. If your disk is in use, you'll have to schedule a boot time scan the next time you restart.
2. Defrag: Fragmented drives are slower to respond and can use up more space, which is why it's a good idea to keep your hard drives defragmented. You can access this by navigating to Accessories-> System Tools-> Disk Defragmenter or right-click on the drive you want to defrag, and access the Tools submenu. Then click 'Defragment now'. The drive will have to be analyzed first and then defragmented. If your drive is fragmented, it may take a while for this process to finalize but once it's done, your hard drive will run faster and you'll have recuperated a few GB.
3. Glary Utilities There are a few different versions of this software, but the basic one is freeware, so you can use it without any charge. We ran through the different scans a few times to clear up some space.
4. CCleaner: This software will optimize and clean your PC. There are a few different scans you can run through, including a registry scan, which will take care of some malware entries in your Windows registry.
5. nCleaner: This app does similar things as CCleaner, but we like running both of them to ensure that nothing has been overlooked.CleanMyPC: If you have grown to love MacPaw's CleanMyMac, then you can do the same with your PC thanks to this app. However, we found the trial version of the software somewhat annoying, as it would only let us clean 500MB and showed us, almost tauntingly, how much more it could clean if we'd only purchase a license. It's safe to say that if you've gone through the five other steps in this process, you'll have cleaned your PC thoroughly, and you won't have to shell out $29.95 for CleanMyPC. Still, it's a good option if you want a one-stop solution.
