Have you finished upgrading Windows 7 to Windows 10 or installing a new Windows 10 Anniversary Update/Creators Update in recent days? If this post grabs your attention and you click inside, you must run into trouble of Windows 10 update taking up incredibly huge disk space. Usually, that of the System C drive if you didn't choose to install Windows 10 on an external hard drive. I assume that you want to reclaim disk space in Windows 10 very badly.
According to Microsoft, every Windows 10 update requires a certain amount of storage space on your device to help ensure the installation goes smoothly and that it runs well. Otherwise, you'll receive a warning message telling that Windows needs more space if there isn't enough space.
So, how much disk space does the Windows 10 update need exactly? Approximately 20 GB (for 32 bit and 64 bit). That is to say; your hard drive will use 20 GB disk space to make room for tons of Windows 10 update files, including the old updates, temporary files, etc. These are massive dumps of files, and they do not get cleaned up automatically. Indeed, they are useless large files after some time when you don't want to uninstall the update at all.
So, when you see C drive running out of free space after Windows 10 update, your first step shouldn't just spend money on a new larger hard drive. That's not a cost-effective plan. Instead, only a piece of free partition manager software can reduce your cost in making efforts to reclaim enough storage space on a hard drive.

2. Right-click on the System C: drive and select "Resize/Move".
