How can I download Windows Update in Windows 10?

 Sometimes you are not able to download Windows Update. Without Windows Updates chances are your computer/laptop is not working well.

This screen shows the related issues with Windows Update.

Before getting into more diagnostics and web searches you make sure this service is turned in the Control Panel's Services window.

This service is by default 'Manual'. You can 'Start', "Stop" or "Restart" this service in the Control Panel-> Services node.

If you look closer this Windows Service requires another service "Remote Procedure Call" running.

In the Control Panel's Services node you can 'Start', "Stop" or "Restart" this procedure is also "Manual" by default.

If you have to do any of the above, you must have administrative rights over the computer/laptop. 

Even after doing all this if the Windows Update does not work, you should look for other problems.

What happenned to my restore points in Windows 10?

They disappeared because there was an automatic update of the operating system.

One creates system restore points to go back in case there is a problem. Typically when you encounter some rpoblem you would want to go back to a restore point you have created. The restore point would still be available to you were it not for the automatic Windows Updates.

It would be nice if there is a way of having OS on one drive that does not update (so restore points are available) and OS on the other that can update and install the better(?) code.
