Discussion Overview

The discussion revolves around the storage usage of a Windows 10 machine, specifically addressing the high percentage of hard drive space allocated to "System & Reserved." Participants explore the implications of this storage allocation, potential causes, and strategies for managing disk space.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Mathematical reasoning
  • Experimental/applied

Main Points Raised

  • One participant questions whether 55.2GB for System & Reserved is typical for a Windows 10 machine with a 120GB hard drive.
  • Another participant inquires about the amount of RAM in the system, suggesting it may relate to storage usage.
  • A participant notes that if the system was upgraded from an older version of Windows, remnants of the previous OS could contribute to the high storage usage.
  • Some participants suggest that Windows 10 should ideally occupy less space than older versions, indicating that unnecessary files may have accumulated over time.
  • Recommendations include using disk management applications to identify large files and folders, as well as tips for freeing up space by removing unneeded files or adjusting system settings.
  • One participant shares personal experiences of attempting to conserve disk space, expressing regret over lost data after deleting files.
  • Another participant emphasizes the importance of distinguishing between safe deletions of system files and the risks of deleting personal data.
  • A later reply suggests a series of steps for managing disk space, including backups, uninstalling unused programs, and using the Windows Disk Cleanup tool.

Areas of Agreement / Disagreement

Participants express differing views on whether the reported storage usage is normal, with some suggesting it is not unusual while others indicate it may reflect unnecessary bloat. There is no consensus on the best approach to manage the situation, with various strategies proposed and debated.

Contextual Notes

Participants mention the potential for accumulated files from system updates and the impact of upgrading from older Windows versions. There are references to specific tools and methods for managing disk space, but no agreement on their effectiveness or necessity.

Who May Find This Useful

This discussion may be useful for Windows 10 users experiencing high disk usage related to System & Reserved, as well as those interested in strategies for managing limited storage space on their devices.

Is that "normal" for a machine running Windows 10? I have a 120GB hard drive and 55.2GB is being used for System & Reserved. Seems high.

How much RAM do you have?

Did your computer start out with Win 10 or did you upgrade from Win7 or Win8? If you upgraded (not a clean install), significant parts of the old OS are still there. That's probably not the case with your machine - the Windows directory takes up about 94 GB, or about 10% of my main drive. (I have another drive that's about 500 GB.)

How did you get the figures for System and Reserved? I'm running Win 7, and it just shows how much is used and how much is free. 120 GB isn't all that big a drive these days. My computer (desktop) is 3 years old, but when I bought it I wanted it to have a lot of RAM and a lot of disk space.
 
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

Several times in the past I found myself short of storage space. Before investing in a bigger disc, I set out to delete unneeded files. Once, I converted all my pictures to lower resolution.

In every case, I had to upgrade to a newer bigger system anyhow. In every case I regretted my efforts to conserve space and I lost stuff that I would like to have.

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?

the connection is simply that you talked about deleting unneeded files. That's what I did and regretted.

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.​
