Windows 10 updates provide the latest security features and enhancements for your operating system. Therefore, you may need to update your PC regularly. Before the installation process begins, Windows will verify that you have enough storage space on your internal drive.

If you do not have enough disk space, you will see a pop-up message that says: Windows needs more space. This shouldn’t stop you from updating your Windows 10 PC. We will show you how to solve this problem.

How Much Disk Space Do You Need to Update Windows 10?

According to Microsoft, whether you are using a 32-bit or 64-bit Windows operating system, you need at least 32GB of free disk space to upgrade to the latest version of Windows 10. If it is less than this amount, you may encounter a “Windows needs more space” error.

On some devices, such as Windows 10 tablets with only 16 GB or 32 GB storage space, you can save more disk space by installing the Windows 10 Compact operating system.

Otherwise, you can free up space on the hard drive in the following four ways to complete the Windows update.

1. Clean Up Your Disk Drive

When there is not enough disk space for Windows 10 updates, you can create more space by cleaning the drive where Windows 10 is installed. For most people, that is the C: drive.

The Windows 10 Disk Cleanup Tool can help you solve this problem. It will quickly scan your disk for files that you can delete from your PC without having to make changes in Windows 10.

Using Disk Cleanup Tool is a good way to create enough disk space without affecting important files. You can start using the tool in the following ways:

  1. Type Disk Cleanup in your Start menu search bar and select the Best Match.
  2. When the Disk Cleanup: Drive Selection window pops up, select the C: drive and click OK.
  3. When the Disk Cleanup for Drive (C:) window pops up, click Clean up system files.
  4. Select all the files you want to delete, and click OK to continue.

To create more disk space on the C: drive, you can manually delete some files that you no longer need.

You can first delete a folder named Windows.old, which contains all the old data on your previous version of the operating system. This is the folder automatically created every time Windows 10 is updated. Only delete this folder if you are completely satisfied with the current Windows 10 version and have no intention of reverting to the previous operating system.

2. Extend the C: Drive Using Disk Management

If you cannot free up enough disk space on your PC, then extending the drive is a good idea. This will provide enough space for Windows 10 updates. Of course, this solution only works when there is unallocated space on the disk, but you can always check and find out.

The following is how to expand disk storage.

  1. Type disk part in the Start menu search bar and select the Best Match.
  2. When the Disk Management window appears, check whether there’s unallocated space on the C: drive or not. If you have some unallocated space, right-click the C: drive and select Extend Volume to add the unallocated space.

3. Create More Space By Using External Storage Devices

If you don’t have enough disk space on your PC, you can use an external storage device to complete the Windows 10 update. To do this, you need an external storage device with approximately 10 GB or more of free space, depending on the amount of additional space you need.

To get started, select Start > Settings > Update & Security > Windows Update > Check for Updates.

Windows will display a “Windows needs more space” error message. On the Windows Update page, select Fix the problem. This will start the Windows Update tool, allowing you to update your PC with an external storage device. From here, follow the steps below:

  1. Connect an external storage device with enough free space to your computer.
  2. On the Windows update page, you’ll see an External Storage Device option with a drop-down menu. Select your external storage device from the menu and then click Next to continue.
  3. Follow the on-screen instructions to finish installing the update. Once the installation is complete, you can safely remove your external storage device and restart your PC.

Before using an external storage device for updating your PC, make sure you backup your important files.

4. Find and Remove Large Unwanted Programs Using Third-Party Software

Due to the large files hidden somewhere on the PC, you may encounter the problem of insufficient disk storage space. Windows provides many ways to remove unwanted software, but you may find it difficult to locate some programs manually. You can use third-party software to easily find and delete large programs.

There are many software programs you can use, but we recommend IObit Uninstaller in this article. You have been criticized for including third-party software in your installation, but this is no longer a problem.

You can use the free version of this software to delete all unnecessary large programs. Here is how to use this software to remove unwanted programs from your PC:

  1. Download and install the free version of IObit Uninstaller.
  2. Launch IObit Uninstaller and select Large Programs on the left-hand side pane.
  3. All your large programs will show on the right-hand side pane. Mark all the programs you want to delete and click the Uninstall button.
  4. A window will pop up that says, “Are you sure you want to uninstall the selected programs?” You’ll have the option to create a restore point and automatically remove residual files by checking the relevant boxes. Click Uninstall to complete the process.

Using tools like IObit Uninstaller to remove large programs can ensure that there are no remaining folders, files, and registry entries still taking up disk storage space. However, if you find large files and don’t want to delete them, you can move them to an external storage device or cloud storage to free up disk space.

Update Your Windows 10 PC Any Time

You must update your Windows 10 PC regularly. Protect your PC from system crashes and malware attacks. However, sometimes you will encounter the error “Windows needs more space” when trying to update Windows 10. The solution in this article should help you solve this problem.

When you don’t have enough disk space, instead of looking for more ways to upgrade your PC, consider replacing the hard disk with a larger hard disk. This is a long-term solution to ensure that you will not encounter any disk storage problems in the future. This will allow you to easily install Windows 10 updates at any time.
