Have you ever ever seen how your PC’s storage by no means fairly appears so as to add up? A part of that’s as a result of Home windows reserves a small portion of your storage for system information. A characteristic known as Reserved Storage quietly units apart 5GB to 10GB in your SSD for replace information, cache, and short-term information.
It is not as nefarious because it sounds — there is a rationale behind allocating area to streamline updates — however it’s possible you’ll need to get that area again, particularly you probably have a smaller SSD and area is tight.
Additionally: Do your self a favor and cease shopping for these low-cost SSD drives flooding the market
Most customers with 512GB or extra of storage need not mess with these settings, however in case you actually need to maximize your SSD, Home windows permits you to disable Reserved Storage.
Begin right here first
Should you’re hurting for area in your native drive, there are a number of different choices I like to recommend exploring first — lots of which may produce even higher outcomes. First, think about clearing the cache in Home windows 11, a protected technique to unencumber some area.
Second, Home windows PC Supervisor is a free cleanup device that helps determine litter in your machine. Because it’s designed by Microsoft, it ought to theoretically be capable to determine some information that third-party applications cannot, like previous Home windows log information and set up litter.
Additionally: I used an M.2 PCIe enclosure for knowledge storage, and it made file transfers a lot sooner
We wrote an intensive information on learn how to get PC Supervisor, however the tl;dr is that you would be able to obtain it from both its product web page or the Microsoft retailer. While you first run it, run a well being test, then let it clear up disk area.
The way to flip off Reserved Storage
Should you’ve already gone by these steps and need to claw again each spare byte of your SSD from Home windows, this is how one can flip off Reserved Storage. First, navigate to settings in Home windows, and go to System > Storage. As soon as on this tab, click on the “Present extra classes” tab, then navigate to System & Reserved.
Should you scroll to the underside, you may see “Reserved Storage,” together with how a lot your system has put aside for this function. Once more, this might be most impactful for techniques with very restricted storage. When you have 512GB or extra and solely 10GB or much less reserved for Home windows, it is in the end negligible and can possible have little to no affect in your system.
Additionally: How a lot RAM does your PC really want in 2026? A Home windows and Mac professional weighs in
To place that in perspective, 10GB is just not even 2% of a 512GB.
To proceed with turning off Reserved Storage, you may must enter a command line. Click on Begin > Command Immediate, right-click and choose “Run as Administrator.” Then kind or paste within the following command:
DISM.exe /On-line /Set-ReservedStorageState /State:Disabled
Restart your pc, and navigate again to the display screen you simply visited in Settings > System > Storage > System & reserved. Click on “Present extra classes”, and word that the place you beforehand noticed an quantity for Reserved Storage, it ought to be clean.

You may need to flip the characteristic again on once more when it is time to replace your PC. It is easy sufficient to take action, simply kind the identical command line, however change the final half to Enabled.
DISM.exe /On-line /Set-ReservedStorageState /State:Enabled
I do not blame you if you need better management over how Home windows makes use of storage in your PC, however there’s solely a lot you are able to do once you’re working with severely restricted area. Except you are on a secondary machine or a Chromebook, I would not think about something lower than 512GB of storage for a primary driver PC.
Additionally: Do not ignore your desktop PC’s empty M.2 slots – they’re extra helpful than you assume
The perfect answer is so as to add extra storage, whether or not that is upgrading the onboard SSD or utilizing exterior storage. We have examined a number of within the final 12 months, together with moveable choices like this 1TB SanDisk ExtremeFit that is most likely smaller than your mouse dongle, or this large 4TB Samsung T9 moveable SSD, with sufficient area to final indefinitely for some customers.
No matter you do, although, steer clear of low-cost SSDs that appear too good to be true, as we have discovered a number of gadgets that have been both unreliable or straight up DOA.
