2. Sync Date and Time

As per Microsoft, you may also encounter this Exception Code 0xc000027b if the date and Time don’t match with the Time Zone where you reside. Go and check if this is the actual reason behind receiving such error codes. Here’s how the process goes –

First of all, navigate to the following path –

Select Date & Time on the left column.
On the right pane, enable both i.e. “Set time automatically” and “Set time zone automatically” toggle switches.

That’s it, the Date & Time instantly get updated on your device.

Note: If the problem persists even after this, re-visit the above path, and this time hit Region on the left pane. On the right side, select the country where you reside using the drop-down menu.

3. Uninstall and reinstall the faulty app

If you are getting this Exception Code 0xc000027b while starting a single app, the problem may lie in the app itself. In such a scenario, what you should do is uninstall the faulty application and restart your device. When Windows 11/10 reloads, check if the above error resolves or not.

4. Exception Code 0xc000027b by resetting Microsoft Store

If the Exception Code 0xc000027b appears randomly while starting any program, this error might not be associated with a single application. Instead, the whole Microsoft Store has become corrupted. In order to fix this bug then, you must reset the entire Windows Store. To do so, use the steps –

Launch the Command prompt as an Administrator.
On the elevated console, type the following and press Enter –

WSReset.exe

Restart your computer next and see if resetting Store indeed solves the above problem or not.

5. Uninstall then Reinstall Windows Store via PowerShell

We have presented below the PowerShell way to uninstall and then reinstall the Microsoft Store app on your Windows 11/10 PC. All you require is to follow these easy steps –

Press Win + X to launch the Power Menu and select Windows PowerShell (Admin).
On the elevated blue console, copy/paste the below cmdlet and press Enter –

$manifest = (Get-AppxPackage Microsoft.WindowsStore).InstallLocation + '\AppxManifest.xml' ; Add-AppxPackage -DisableDevelopmentMode -Register $manifest

Running the above code alone should uninstall/reinstall the Microsoft Store. If not, close the PowerShell window, and restart it as an Administrator. This time, execute the below code –

Get-AppxPackage | ForEach-Object { Add-AppxPackage -DisableDevelopmentMode -Register ($_.InstallLocation + '\AppxManifest.xml')}
