Windows 10: Windows 10 Store/Apps stopped working

A week ago I tried to install WhatsApp application from store which didn't open after installation (giving an error). After that everything started falling apart. After a couple of restarts all of my store apps started throwing errors on launch (path of the app followed by "The parameter is incorrect.") and today store doesn't even open... I can't understand how you can mesh such the code with so serious bugs, it is just impossible. but still possible as it seems.

Windows 10 Tweaks

As you may already know, Windows 10 (as well as Windows 8) allow you to log in with a valid Microsoft account, instead of creating a local account that only works on your machine. However, you may prefer to keep a local account for privacy reasons. If you do, though, some Windows 10 features—like Cortana—may not work. Despite the default behavior, the Windows 10 Store is not one of them. You can still log in to your Microsoft account for just the Store without switching to a full Microsoft account. The process, however, is not terribly obvious. To do so, follow these steps:

• Launch the Store from your Start menu.
• Click the user icon next to the search box.
• Click “Sign-in” from the menu that appears.
• Choose “Microsoft account” and log in like normal.
• When the “Make it yours” box appears do not enter your password. Instead, click “Sign in to just this app instead.”

Hi Sumon,

Sorry for the delay in response.

• Do you face this issue only with these apps?
• Did you try downloading other apps?
• Did you try stopping these apps and then downloading it again?

We would suggest you to try the steps mentioned in the link

• Type troubleshooting in the search
  box and hit Enter.
• Click View all from the left pane and select Windows store apps.
• Follow the on-screen instructions and check.

If the steps don't work try these steps:

Try to reset the Windows store and check.

• Press Win + R on the keyboard to open run Window.
• Type wsreset.exe to reset the Windows store cache.

Hope this information helps.
