Hey there, dineshlamror
Welcome to the Microsoft Community forums.
You are running on a version of Windows 10 that is no longer supported by Microsoft. You will need to update your version of Widows, via Windows updates. Please make sure, for best protection, you keep up to date with Windows updates.
Please can you go to this site here: https://www.microsoft.com/software-download/windows10 and download the Windows Update Assistant.
Once this has downloaded, please try updating Windows though the update assistant.
Hope this helps,
Regards,
