Windows 10 Free up disk space

This article introduces how to free up disk space on Windows 10 (32 & 64 bit) with Disk Cleanup and additional 10 methods.

Many people feedback that system C drive becomes full after upgrading to Windows 10 or install some Updates, because there are many large files downloaded and write into C drive. In fact, system partition is filling up by many types of files continuously, so it runs out of space sooner or later if you don’t take care. It’s more likely to encounter this issue if you use SSD, because it is much smaller than traditional mechanical hard disk.

If you want to enable it:

Type powercfg.exe -h on
