Start with the built-in options first: Settings → System → Storage, then Cleanup recommendations / Storage Sense. I’d also check Downloads, Recycle Bin, large personal media folders, and Apps sorted by size before touching anything under C:\Windows or Program Files. A visual disk-space map can help you see which folders are actually large, so you don’t delete blindly. Back up anything uncertain before moving or deleting it.

Windows automatically creates restore points that help you revert your system to a previous state. However, these points can accumulate and take up valuable space over time.

It allows you to remove old restore points in one go, but using this feature requires caution to avoid deleting the only valid restore point.

First, open Settings: Go to Settings > System > About. Under Related settings, click on System Protection. Select the C: drive and click Configure.

Once in the configuration menu, you’ll see an option to Delete old restore points. If you don’t need them, deleting them will free up storage on pc. Just make sure you have a recent restore point before you delete old ones, just in case something goes wrong.

Once the deletion is complete, you can close the window and continue using your PC normally.

This method only targets restore points, but it is a safe and straightforward way to free up storage on pc without risking system stability.

If you don’t want to use third-party cleaning software, you can try this method. This is a simple maintenance measure, but you should make sure to keep at least one restore point available.

Removing apps you no longer need is an effective way to free up storage on pc and reduce unnecessary system load. Cleaning out redundant software regularly also helps greatly free up storage on pc for smoother computer operation.

How to free up storage on pc

Step 1: Go to Settings > Apps > Apps & features

Step 2: Sort by size under Apps & features to organize your installed apps by size, making it easier to quickly identify unused apps that are taking up a lot of space.

Step 3: Uninstall unnecessary apps. Review the list of apps, select the ones you rarely use, and then tap Uninstall.

Step 4: Uninstall pre-installed bloatware to further reduce unnecessary files.

Tip: Be careful not to uninstall system apps unless you are absolutely sure they are not important for your PC's functioning.

Regularly performing this simple cleanup habit keeps your disk space organized, reduces background resource consumption, and maintains long-term stable performance for your Windows device.

Cons
