The solution to your problem will depend on when you saw the error. That is why we recommend you go through the solutions below and see what aspect of the system the error is likely associated with.

Possible Solution #1: Fix Broken Registry Entries.

Here’s how:

  1. Click on the Start button.
  2. In the search box, input regedit.exe and hit Enter.

That is why we strongly recommend the use of a trustworthy registry cleaner to fix broken registry entries for you.

Possible Solution #2: Modify Your Region and Language Settings.

Possible Solution #4: Delete or Rename the Software Distribution Folder.

The Software Distribution Folder is where all the installation and update files are stored. Since error 0x80070057 is also associated with these files, you may try to fix it by deleting or renaming the Software Distribution Folder.

To rename the folder, follow the instructions below:

Possible Solution #5: Disable Your Built-in Antivirus or Firewall.

  1. Click Start.
  2. Go to Control Panel.
  3. Select System and Security.

Possible Solution #6: Clear System Junk.

If error 0x80070057 still shows up to this point, then you may want to try clearing your system of junk files. It is likely that these files are messing up your system process, hence random errors appear.

To clear system junk, you can manually go over one folder to another. However, be mindful that this can be very time-consuming, not to mention there are risks involved. If you delete an important file, it is possible that you can affect your whole system.

The best and most efficient way to clear system junk is to use a reliable PC cleaning tool. In a few clicks, all junk and unnecessary files are deleted.

Possible Solution #7: Consult a Professional.

Do not lose hope if none of the six solutions above worked. Perhaps there’s an underlying problem with your hardware that needs to be resolved.

If you suspect that a certain hardware is failing or causing the error, bring your computer to the nearest service center. Have a professional check on it and ask for the most appropriate solutions.


The methods above have already been tried by many. But that does not suggest they will work for you as well. Again, the right solution depends on what’s causing the error to appear. So do not be discouraged if the first few methods you’ve tried do not work. Keep on trying until you hit gold.
