Is your hard disk drive or solid state drive filling up fast? Want to free up disk space on your Windows 10 PC? In this guide, we will discuss all the ways out there to free up drive space in Windows 10.

You can free up GBs of disk space on your PC with a little bit of work. In this article, we will list out all the possible ways out there to free up space on your Windows 10 PC.

In no particular order, following are the 19 ways to free up drive space in Windows 10.

Uninstall unwanted apps and programs

You are aware of this, and probably have done this already. If not, uninstall unwanted programs and apps right away to free up disk space. Some of the programs out there consume GBs of valuable disk space.

By navigating to Settings app > Apps > Apps & features you can view disk space being used by apps and programs. You can also uninstall apps and programs right from this page.

You can also consider uninstalling not so useful native apps to free up drive space in Windows 10. Refer to our how to uninstall default apps in Windows 10 guide for instructions.

Turn off hibernation to free up drive space

Before you start complaining, let us make it clear that we suggest to turn off the hibernation feature only if you are not using it or don’t know what the hibernation feature is.

Hibernation feature, when turned on, creates hyberfil.sys file which takes about the size of the RAM installed on your PC. For instance, if your PC is equipped with 8 GB of RAM, the hibernation feature takes about 7 GB of disk space.

Remember that hibernation feature is turned on by default in Windows 10 but it’s not added to the Start menu by default. So, make sure that it’s turned off if you don’t use it. And if you don’t want to turn it off, consider reducing the size of the hibernation file.

Here is how to disable the hibernation feature

Step 1: Open Command Prompt as administrator by typing CMD in the Start/taskbar search field, right-click on Command Prompt entry and then click Run as administrator.

Step 2: In the elevated Command Prompt, type powercfg /hibernate off and then press Enter key to turn off the hibernation feature and free up space.

Disable or delete system restore points

System restore points come in handy when you want to restore your Windows 10 PC to an earlier date to fix issue(s). Depending on the number of restore points and allocated space for the system restore point feature, it might be taking GBs of disk space. Again, turning off system restore feature is not recommended, especially if you know how to use it!

Alternatively, you can delete all restore points except the most recent one if you don’t want to turn off the feature. There are also ways out there to delete individual restore points.

Here is how to turn off system restore feature.

Step 1: In the Start/taskbar search field, type sysdm.cpl and then press Enter key.

Step 2: Switch to the System Protection tab. In the Protection Settings section, select a drive and then click the Configure button.

Step 3: In the resulting dialog, select Disable system protection radio button, and then click Apply button.

Repeat step 2 and 3 for other drives to completely turn off system restore feature for all drives and free up drive space in Windows 10.

Clear the Recycle Bin

You probably know that when you delete a file in Windows 10 by selecting a file and then pressing the Delete key, the file is moved to the Recycle Bin. As long as a file is in the Recycle Bin, it continues to take the disk space. You can reclaim valuable disk space by allocating less disk space to the Recycle Bin and clearing all files from the Recycle Bin.

If you often find yourself doing Shift + Del to permanently delete files without moving files to the Recycle Bin, you should consider turning off the Recycle Bin. We recommend you configure Windows 10 to automatically delete old files from Recycle Bin.

Delete old versions of drivers

Just like older versions of software, old drivers of no use and take up disk space. Luckily, Windows 10 allows you to delete old device drivers with ease. Please refer to our how to delete old device drivers in Windows 10 guide for step-by-step directions.

The Windows.old folder contains data from your previous Windows installation(s) and takes no less than 10 GB of drive space. If you are sure that you don’t need data from previous Windows installation(s), you should delete the Windows.old folder to free up considerable amount of disk space.
