Way 8: Stop Using the System Restore Points

Windows 10 set the System Protection to ON by default after the system installation, and this will take at least 3% drive space of your current storage for saving the restore points; hence, by disabling the system restore, you will have a luck to free up drive space for approximately 1 – 3 GB (It should depend on how large of your storage drive is):

Step 1: Type Control in the Run dialogue box after pressing Win Logo + R.

Step 2: Click System and Security option, and then navigate to System, click on it.

Step 3: On the left panel, find the System Protection and then Configure.

Note: System protection is created to automatically save the system changes that allow you to restore to the previous points once in need. If you are happy with this feature, skip it to the next method.

Way 9: Use Free Up Space Now

Starting with Windows 10, Storage Sense is a feature that devoted itself to optimizing your storage. It monitors your system for old and unused files, and then actively removes them on a regular schedule. You can also use the “Free up space now” feature in Storage Sense with the following steps:

Step 1: Navigate to Settings > Systems and click on Storage on the left panel.

Step 2: Click on Configure Storage or run it now.

Note: The Storage Sense task can be enabled automatically on Every day, Every week, Every month, or during low free disk space. Select one of the schedules if you don’t like to do it on your own.

Way 10: Change File Storing Destination

As Windows 10 set the file storing destinations to the first partition of your hard drive by default, which means you will have all of your new apps, documents, music files, photos, movies, and TV shows, offline maps being saved to the partition C. Hence, if you want to change the file storing destination to free up space for partition C, use the following steps:

Step 1: Navigate to Settings > Systems and click on Storage on the left panel.

Step 2: On the right page, scroll down to the More storage settings, and then click on Change where new content is saved.

Step 3: Click on a drop-menu of an option, choose a different drive, and then click on Apply.

Change File Storing Destination

Generally, if you have processed all of the above methods, you might be satisfied with the cleanup result as tons of the undesired/temporary files have been wiped out and a large enough free drive space has been claimed; however, if you are still willing to get more free drive space. Here are the five advanced solutions that can be selected.

Advanced Solutions for Free up Drive Space

Solution 1: Disable Hibernate

Hibernation is a mix between a traditional shutdown and sleep mode designed for laptops. When you put your PC to hibernate, open programs and documents will be saved to the hard disk before turning off the PC. Then when it’s time to restart it, all your previous work is ready and waiting for you. However, if a quick way to start up your computer doesn’t matter to you, by disabling it, you can free up drive space allocated to the hibernate-saved files.

Step 1: Press Win + Q, type in Command Prompt, right-click on it and select Run as administrator.

Step 2: In the Command Prompt window. Enter: powercfg /hibernate off and then hit Enter.

Note: By disabling hibernate you will free up a large amount of the drive space according to how big hibernate files have been saved; However, if you would like to enable Hibernate some times later, enter this command:powercfg /hibernate in the command prompt window.

Solution 2: Enable Compact OS

Compact OS is a built-in tool offered by Windows 10. Although it is usually used for a device with limited storage capacity, it could be helpful if you are in immediate need of extra space. You should be noted that the alteration of system files could put the computer at risk of severe damage, and you need to make sure that you have made a temporary backup of your PC before proceeding this solution:

Step 1: Press Win + Q to open Search, Type in Command Prompt, right-click on it and select the Run as administrator option.

Step 2: To compress the installation of Windows 10 and its apps, type in the following command, and press Enter: compact.exe /compactOS:always

Enable Compact OS

Note: To revoke the command, follow the same steps, but on step 2, use another command: compact.exe /compactOS:never.

Solution 3: Disable Reserved Storage on Windows 10

Since the May 2019 Update, Windows 10 adds a new feature named as Reserved Storage, which allocates gigabytes of space for system caches, updates, and temporary files. Although disabling it can reclaim the storage space, it’s not a preferred method since it may put the computer at risk. But if you are well-informed about the feature, you can use the following steps to disable it.

Step 1: Type in PowerShell in the Search Bar, right-click on it and select the Run as administrator option.

Step 2: To confirm if the feature is enabled, type in the following command and press Enter: Get-WindowsReservedStorageState

Step 3: To disable the feature, type in the following command and press Enter: Set-WindowsReservedStorageState -State disabled

Disable Reserved Storage

Solution 4: Store Local Files to Onedrive

Windows 10 has embedded OneDrive automatically for the first installation of the system, and each user will have at least 5 GB storage space for free. Then the users can choose to store files to OneDrive and make them available online manually. We can use the following steps:

Step 1: Click on the OneDrive in the lower-right corner of the taskbar.

Step 2: Sign up for a Microsoft account, and then log in to the OneDrive.

Step 3: Send all of the desired files to OneDrive. After that, delete the local files to clear the drive space.


Note: After storing files to OneDrive using this solution, you are able to access the files via OneDrive and view them anywhere you like. However, there’s only 5 GB for free, and if you want to get more free cloud storage, you should buy from Microsoft.

Solution 5: Use Third-Paty Cleaning Utility

There are many third-party cleaning utilities out there in the market, but you should be noted anywhere on the Internet or by your friends, colleagues that CCleaner is the king; CCleaner is a powerful drive space cleaning software that developed by Piriform, it can clean up all the potential unwanted files or Windows registry entries from your computer, and it’s easy to be used with the following steps:

Step 1: Download the software from its official website, and then install it.

Step 2: Launch the software, and then click on the Custom Clean on the left panel.

Step 3: Under the two tabs, Windows and Applications, select the type of data you want to delete.


Step 4: Click on Run Cleaner at the lower-right corner.

What if your vital photos, videos, documents, or any types of the files might have been cleaned up accidentally after using the Shift+delete key or the third-party cleaning utility; don’t worry, accidental deletion isn’t a final command to completely wipe the data up, as the file system still keeps the file contents saving on the hard drive and it just marks the disk space for the deleted files as free for later overwriting.

Hence, we need to hurry up by using the third-party data recovery software – Bitwar Data Recovery before the desired files are getting lost permanently.
