My desktop PC can no longer receive Windows 10 updates.

Below is the error message that has come up over and over again, for the past 2 months:

2020-06 Cumulative Update for Windows 10 Version 1909 for x64-based Systems (KB4560960)
Status: Download error - 0x800700c1

Currently, I have Windows 10 Home (64-bit) v. 1909, build. 18363.720.

I also have another computer (a laptop) with Windows 10 Home (64-bit) and all the Windows 10 updates have worked fine, including the latest "May v.2004" update.

Can you help me with my desktop computer? I'd like to be able to continue installing new Windows updates on it.

Thank you.
