Nearly 50% of my hard drive is System & Reserved

How much RAM do you have?

I agree with @Mark44 that 120G is pretty small these days. Still, what I read about Windows 10 suggests that it ought to install in far less space than previous Windows versions, and much less than 52G; which means that somehow you may have accumulated unnecessary bloat. I do remember that older versions of Windows would acquire crud quite quickly, e.g. packages required for updates would be kept on even though no longer needed. I'd suggest two things:

1) If you haven't already, get yourself one of the various apps that shows disk storage graphically via clusters of folders & file types, so that you can look inside your System folder, for example, and quickly zero in on the files or groups of files that seem to be hogging up space; you can Google on the various folder & file names to learn what they do & whether they need to be kept. That's how I always did it when I was still running Windows, up until last year. As for what app to use, Windows 10 apparently has an improved feature for managing disk space, but I've always preferred third-party apps for this purpose. The freeware WinDirStat still seems to be getting recommendations even though it doesn't say that it's been updated for 10: https://windirstat.net

2) Assuming you find and remove any unneeded files, with only 120G you may find you want still more room; in which case you can look for articles with tips on shrinking Windows, e.g. by turning off hibernation, etc. - see for example https://www.laptopmag.com/articles/reclaim-disk-space-windows-10

 

I don't know why you're quoting my post as part of your comment, given that there is zero connection between what you did & what I am suggesting to the OP. In terms of being helpful, maybe you could explain how you went about getting more storage?

 

No, you did not do what I talked about: I talked about safe deletion of certain Windows system files in cases where they aren't needed, e.g. a hibernation file. What you did was delete/degrade data files that you now wish you had back. I'm sorry for your mistake; but please leave me out of it.

 

I would say this is not unusual, especially for a system using an OEM install. I suggest you perform the following in order:

1. Windows System Image backup to USB (for full system recovery).

2. File History backup to USB (for easy file/directory recovery).

3. Uninstall programs/apps you don't use.

4. Run the Windows Disk Cleanup tool in admin mode to remove Windows upgrade, update, and temp files.

5. Migrate to a larger drive if you need more space.​
