Setting the time and date
In many documented cases, the error code 0xc000027b is a direct result of the fact that the date, time or time zone was changed during the upgrade of the machine’s operating system. Several users concerned confirmed that the problem for them was that the clock on their machine was incorrect.
This may seem insignificant, but it is possible that some store requests may fail due to incorrect time stamping and the store server may not allow the connection to be established. If this scenario is applicable, setting the correct time, date and time zone should allow you to solve the problem very easily.
Clear the store’s cache memory
Emptying the shop cache can help solve problems when installing or updating applications. In fact, emptying the cache can solve many Windows problems. It is incredibly easy to use and takes only half a minute to use.
Press Windows + R to open Run, then type wsreset.exe and click OK. An empty prompt window will open, but you can be sure that it will clear the cache. After about ten seconds, the window closes and the store opens automatically.

- Press Windows + R to open a Run dialog box. Then type ‘powershell’ and press Ctrl + Shift + Enter to open a elevated Powershell prompt. When User Account Control (UAC) is displayed, click Yes to grant the required administrator access.

- $manifest = (Get-AppxPackage Microsoft.WindowsStore).InstallLocation + ‘\AppxManifest.xml’ ; Add-AppxPackage -DisableDevelopmentMode -Register $manifest
- Once the command has been successfully executed, restart your computer and check that the problem is solved the next time you start your computer.
