Welcome to the forum Shifat,
In you case the error screenshots hint at an issue with the Windows Update service.
You could try the following to see if things improve:
- Right-click on Start then left-click on Run
- In the run dialog type services.msc then click OK
- When the Services window opens scroll down the the following three Services:
- Background Intelligent Transfer Service
- Cryptographic Services
- Windows Update
On each of the above three services, double-left click to open.
A smaller window will pop up. In the middle of these windows you'll see Startup type: with a drop arrow menu to the right
In all three Services click the drop arrow and choose automatic then click OK
With any luck that may resolve your issue and allow the Windows Update Service to complete its tasks.
