How to Free Up Storage Space
on a Windows Laptop

A full drive slows Windows, blocks updates and stops you saving files. Here is how to see what is eating your space and clear it safely, using only built-in tools.

✓ Fact-Checked
⚡ Quick Answer

Open Settings → System → Storage. First run Cleanup recommendations, then open Temporary files and clear Windows Update Cleanup, Delivery Optimization Files, Thumbnails, the Recycle Bin and, if you will not roll back, Previous Windows installation(s), which can be many gigabytes. Then switch on Storage Sense so Windows keeps tidying automatically, uninstall apps you no longer use, and use OneDrive Files On-Demand to make synced files online-only. Aim to keep roughly 15–20% of the drive free. If you keep fighting for space after all this, the drive is too small for how you use the laptop, and a bigger SSD is the real fix.

Many affordable business laptops, including a lot of the refurbished ThinkPads and Latitudes sold in Kenya, ship with a 256GB drive. That is plenty for documents and email, but it fills quickly once Windows updates, a few large apps, downloaded files and a synced cloud folder pile up. When the drive gets close to full, Windows slows down, updates fail to install, and you cannot save new files.

The good news is that most of the recoverable space sits in a handful of predictable places, and Windows 11 has built-in tools to clear them safely. This guide shows you how to see what is using your space, then works through ten ways to reclaim it, ordered roughly by how much they usually recover. If your laptop is also sluggish, our slow laptop guide shows how to tell whether storage is really the cause.


Step Zero: See What Is Actually Using Your Space

Do not delete anything blindly. Look first.

01
Open the Storage Page
Go to Settings → System → Storage. Windows shows how full your main drive is and breaks usage into categories such as Apps & features, Temporary files, Documents, Pictures and Other. Click a category to drill in. The biggest bar is where to start.
02
Check How Much You Really Have
Open File Explorer → This PC and look at the bar under your C: drive. If less than about 15–20% of the drive is free, Windows will struggle, and that is your signal to work through the steps below.
Where the space usually hidesTypical recoverySafe to remove?
Previous Windows installation(s) (Windows.old)Large, often 15–30 GBYes, but ends rollback

The 10 Ways to Free Up Space — Biggest Wins First

Use the built-in tools before reaching for any third-party cleaner.

01
Run Cleanup Recommendations
In Settings → System → Storage, choose Cleanup recommendations. Windows groups suggestions into temporary files, large or unused files, files already synced to the cloud, and apps you rarely use, and shows a running total. You tick what to remove, so nothing is deleted without your say-so. This is the lowest-risk, highest-return first move.
02
Delete Temporary Files
Open Temporary files on the same Storage page. Review the list and tick Windows Update Cleanup, Delivery Optimization Files, Thumbnails, Temporary files and the Recycle Bin. Read the descriptions as you go, and leave your Downloads category unticked unless you have checked it, because it holds files you may still want.
03
Remove Windows.old (Previous Windows Installation)
After a major Windows update, the old version stays behind so you can roll back, and it can take many gigabytes. If your laptop is working fine, tick Previous Windows installation(s) in Temporary files and delete it. Do it this way rather than deleting the folder by hand. Once it is gone you cannot roll back to the earlier version, so only do it when you are happy with the current one.
04
Turn On Storage Sense
Switch on Storage Sense on the Storage page and open its settings. Tick the option to keep Windows running smoothly by cleaning temporary system and app files, and choose to run it when disk space is low or on a weekly schedule. You can also empty the Recycle Bin after a set number of days and optionally clear old files from Downloads. Run it once manually to see what it clears.
05
Uninstall Apps You No Longer Use
Go to Settings → Apps → Installed apps, sort by Size, and uninstall large programs and games you have stopped using. You can always reinstall them later. Apps are often the biggest long-term space users, so this is worth a careful look every few months.
06
Use OneDrive Files On-Demand
If you sync OneDrive, each downloaded file also sits on your laptop. In File Explorer, right-click a large folder or file and choose Free up space. It stays visible in OneDrive but becomes online-only, and downloads again when you open it. You need an internet connection to open online-only files, so keep offline copies of anything you need without a connection.
07
Sort Out Downloads and Large Files
Open your Downloads folder in File Explorer, set the view to details, and sort by Size. Old installers, duplicate downloads and large videos are common space hogs. Delete what you no longer need and move anything you want to keep, such as photos and videos, to an external drive or cloud storage.
08
Clear Browser and App Caches
In Chrome or Edge, press Ctrl + Shift + Delete, choose Cached images and files and clear them. Browsers, chat apps and creative tools store caches that grow over time. Clearing them is safe, though sites may load a little slower the first time you revisit them.
09
Run Disk Cleanup for System Files
Search the Start menu for Disk Cleanup, select your C: drive, and click Clean up system files. This can expose extra categories such as Windows Update Cleanup and previous installations that the first pass missed. Tick only what you understand, and read each description before you confirm.
10
Optional: Turn Off Hibernation
Windows keeps a hidden hiberfil.sys file that can take several gigabytes. If you never use hibernate, open Terminal or Command Prompt as administrator and run powercfg /hibernate off to remove it. This also turns off hibernate and Fast Startup, and you can reverse it any time with powercfg /hibernate on. Skip this step if you rely on hibernate.

🚩 What Not to Do When Freeing Up Space
  • Deleting files inside the Windows folder, System32 or WinSxS by hand — this can break Windows. Use the built-in cleanup tools instead.
  • Deleting the Windows.old folder manually — remove it through Temporary files so Windows cleans up properly.
  • Installing "PC booster" or registry cleaner apps — the built-in tools do the useful work, and these apps often add risk without freeing meaningful space.
  • Deleting program folders instead of uninstalling — leaves leftovers and can cause errors. Uninstall from Settings → Apps.
  • Clearing space without a backup of important files — back up documents, photos and anything irreplaceable before any big clean-up.

If you have worked through all ten and the drive still fills up within weeks, the drive itself is too small for how you use the laptop. At that point the real fix is more storage, usually a larger SSD, rather than another round of cleaning. Whether a particular model can take a bigger drive depends on the laptop, so check the exact model first. Our spec-checking guide shows how to read your drive type and size.

Frequently Asked Questions

Direct answers on freeing up storage space on a Windows laptop.

  • Open Settings, then System, then Storage. Run Cleanup recommendations to see temporary files, large or unused files, files already synced to the cloud and apps you rarely use, then open Temporary files and delete the categories you don't need. Finally switch on Storage Sense so Windows keeps clearing temporary files automatically. These three steps use only built-in tools and recover space with little risk.
  • Yes, if you don't need to roll back to the previous version of Windows. Windows.old holds the files from your earlier Windows installation after a major update, and can take many gigabytes. Remove it through Settings, System, Storage, Temporary files, by ticking Previous Windows installation(s), rather than deleting the folder by hand. After you remove it you can no longer roll back to the old version.
  • Storage Sense is a built-in Windows feature that automatically clears temporary files, empties the Recycle Bin after a period you choose, and can clean old files from the Downloads folder. It can run on a schedule or only when disk space is low. Turning it on is a sensible low-effort way to stop storage filling up again, especially on laptops with a small drive.
  • Yes. If you sync OneDrive, each downloaded file also takes room on your laptop. Right-clicking a file or folder in File Explorer and choosing Free up space turns the local copy into an online-only placeholder that still appears in File Explorer and downloads again when you open it. It needs an internet connection to open those files, so keep offline copies of anything you need without a connection.
  • A common rule of thumb is to keep roughly 15 to 20 percent of the drive free. Windows needs room for updates, temporary files and virtual memory, and a nearly full system drive can make a laptop slow. If you keep having to clear space just to stay above that level, the drive is too small for how you use the laptop.

A full drive is one of the most fixable problems a laptop has. Windows already includes the tools to find the space and clear it safely, and the biggest gains usually come from just a few places: leftover update files, an old Windows.old folder, apps you no longer use and cloud files kept locally. Clear those, switch on Storage Sense, and most laptops stay healthy for a long time.
