Web Credentials showing Error 0x80070057 "The parameter is incorrect"

I am running windows 10, it has been working fine for a while.

Recently I got a notification in the Action Center. It said:

Click here to enter you most recent credential 
Your Microsoft account needs you to sign in again

Clicking the notification eventually lead me to the Credential Manager. But when I click the Web Credentials tab, I get the following error

Credential Manager: Error An error occurred while performing this action. Error code: 0x80070057 Error Message: The parameter is incorrect.

No web credentials are shown. Nothing is listed below the Web Credentials heading.

I don't know why. I'd like to fix it. I'm pretty sure that the Web Credentials has worked before.

I have tried these remedies with no improvement:

  • Restarting the computer
  • Modifying the Credential Manager startup type. It was on Manual, but setting it to Automatic did nothing (In both cases, it was already running)
  • Setting Edge to the default browser (was Chrome)
  • Erased all managed passwords in Edge

You can fix the problem by removing the contents of this folder

C:\Documents and Settings\<USERNAME>\AppData\Roaming\Microsoft\Protect

Doing so will erase all login credentials for all apps for your user account! That is all usernames and passwords, including those inside Google Chrome.

But after having done that, the Web Credentials tab seems to work again.

Thanks to Kapil Arya who added this solution to his post.

There is another possible solution.

Solution 1: Add a registry key value

  1. Click Start button and type Regedit.exe in the search box and hit Enter key.

  2. Now you can see the Registry Editor. Try to find out the registry subkey following the path below and click it: HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\SystemCertificates

  3. Click the Edit menu and move mouse to New and then click DWORD Value. Next right-click CopyFileBufferedSynchronousIo and click Modify.

  4. Type 1 and click OK on the Value data box. Exit Registry Editor and restart your PC.
