Hello RAJESHKAN, welcome to the Microsoft community my name is Luiz Cruz, I am a Windows 10 expert user and would be happy to help you;
This error code 0x800706BE is usually linked to system updates;
Are you able to update the system normally?
Is the time on the taskbar blinking?
It would be nice if you could provide a picture of the moment the problem occurs;
I await news, see you soon!
