How to fix Windows 10 Update error code 0x80070070

Ah, Windows updates. They always work! (We’re kidding…)

Windows Updates are still failing with random and stupid error codes. Don’t stress it; we’re here to help! Windows Update error code ‘0x80070070’ is one of the more common errors – let’s get it fixed!

If you’ve got any other error codes, we do have a generic error code check to take a quick look! Find it here.

Error code ‘0x80070070’ is commonly found in Windows 10 and refers to the amount of space on the ‘OS’ drive. More often than not, the ‘C: Drive’ will be full and will need to be cleared to allow enough space for the Windows 10 update to occur. Let’s look at what we can do about this.

Let’s get this fixed:

  1. Clear Space on your Drive.

As mentioned above, the 0x80070070 update is common, and usually means that you’ve not got enough storage space on the C: Drive for the Windows Update to take effect. Here are some things you can try to clean it up!

  1. Run the ‘Disk Clean-up Utility’.
  2. Remove any files from your computer that you no longer need. (Checking the Downloads folder might be a good place, and if you do delete things, check your Recycle bin to remove them from there too!)

If you’re not sure what specific files mean in the Disk Clean Utility, we have an article on this – so take a look here.

If this fails to help you with your problem, then it may not be directly disk space, so you may want to try the following fixes too.

  1. Use the Windows 10 Update Assistant

One of the ways that we’ve learned to use is using the Windows 10 Update assistant. We should mention that this only works when you are going from one major version (1607,1709,1803,1809 etc.) to the latest. To use this, head over to the Windows 10 download page. This will then show you at the top if you’re able to update with the latest and will give you an option for ‘Update Now’. If you go here and then follow through the steps, you will be on the newer version which can fix many issues, including the update issues.

  1. Reset your Windows Update Services

A common fix to issues with Windows Updates is by restarting the services. Unfortunately, this bit might get a little technical but don’t worry – we’re here to help!

  1. Type ‘Command Prompt’ or ‘CMD’ in your search bar and run it with administrator privileges. (Right-click -> Run as Administrator)
  2. Copy and paste the following commands into your command prompt.

net stop msiserver

net stop wuauserv

net stop bits

net stop cryptSvc

  1. Rename the Catroot2 and Software Distribution folders. You can do this more easily by copying the following commands in the command prompt.
    1. ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
    2. ren C:\Windows\System32\catroot2 Catroot2.old
  2. Restart the services we stopped before by entering the following commands.


net start wuauserv

net start cryptSvc

net start bits

net start msiserver

  1. You may need to restart your PC after making these changes and attempt to check for updates again.


  1. Run the Windows 10 Update Troubleshooter

Windows included the latest troubleshooter to their software called the Windows 10 update troubleshooter.

To get to this, type in ‘Troubleshoot’ into your Windows search bar, and once in the settings find ‘Windows Updates’.

Once clicked, click ‘Run Troubleshooter’ and let it work its magic.

This may require administrative rights if you don’t have it!

We hope that one of these has helped you diagnose your Windows 10 Update issue. However, we do have a ‘mega-thread’ of many more Windows Update fixes if you want to take a look. You can find this here!
