What does error code 0x80070070 mean?

Error code 0x80070070 usually occurs when you perform an upgrade like upgrading to Windows 11, which is a sign that there is not enough free space on the drive you are planning to store the operating system on.

Usually, the Windows 11 ISO file only occupies 4.5GB of space, however, it will expand during the installation process, which can amount to nearly 20GB. Therefore, it's essential for you to free up enough space on the drive, and then upgrade to Windows 11 so that you can prevent such errors during the upgrade.

How to fix error code 0x80070070 Windows 11?

If you want to free up space to fix error code 0x80070070 Windows 11, here are five simple methods that are applicable to your situation.

Method 1. Empty Recycle Bin

Every time when we delete some files or folders, we usually drag them to Recycle Bin where is the place to store deleted files indefinitely. As long as you don't delete the files on it automatically, it will exist forever, which continues to take up the free space on your drive. Here are the steps:

Step 1. Right-click the Recycle Bin.

Step 2. Select "Empty Recycle Bin" from the context menu. Wait for a while and the files will be deleted.

Note: Please check if the files on it are all you no longer need before you empty the Recycle Bin.

Method 2. Clean up disk space

Disk Cleanup, the inbuilt PC cleaner in Windows, is also suggested by Microsoft to get more free space on the C drive. It can delete the files that are usually running on the background to constantly consume the disk space. The steps are as follows:

Step 1. Type "disk cleanup" in the search box and hit "Enter".

Step 2. Select the disk you want to clean and click "OK" to get into "Disk Cleanup" window.

Step 3. Tick the files you want to delete and hit "OK".

Then you will receive a confirm message saying that "Are you sure you want to permanently delete these files?", click "delete files" to perform the deletion. To free more space, you can use "Clean up system files" to remove older Windows restore points from your drive.

Method 3. Uninstall unused apps

Various apps are installed when using the computer, some of them are not used often or won't be used any more. Although they may seem like only 16MB or 86MB, many a little makes a mickle. For such apps, just remove them and you will get a lot of space. Do as the tutorial below:

Step 1. Press "Windows + R" at the same time, type "control panel" and go to "Programs" > "Programs and Features".

Step 2. Select the apps you want to uninstall, right click it and click "Uninstall".
