[SOLVED] Windows 10 update failure

[d373rmined]

I have been unable to get Windows 10 to update. Not sure how long it’s been going on but just noticed it’s failing and when I click to retry I get the following error messages.

Feature update to Windows 10, version 1803 x64 2019-09B - Error 0x800700c1

• 2019-02 Update for Windows 10 Version 1709 for x64-based Systems (KB4346085) - Error 0x800700c1

• Microsoft .NET Framework 4.8 for Windows 10 Version 1709 for x64 (KB4486153) - Error 0x80248007

Please help. I can’t get it to manually update. Thanks so much.

Where did this install come from originally?

Bought the PC through CyberPowerPC. Came pre installed.

Before going any further, it must be noted that a repair install (or feature update, when those are being done) allows one to keep all of one's files and apps (desktop/installed and store varieties). This is in complete contrast to a Reset (which allows either keeping just one’s files or wiping everything), or a Refresh/Fresh Start or Completely Clean Reinstall, both of which wipe everything.

My standard advice, in virtually all cases, (and presuming any potential infection has already been addressed, first) is trying the following, in the order specified. If the issue is fixed by option one then there's no need to go further. Stop whenever your issue is fixed:

1. Using SFC (System File Checker) and DISM (Deployment Imaging Servicing and Management) to Repair Windows 8 & 10

2. Doing a Windows 10 Repair Install or Feature Update Using the Windows 10 ISO file

3. Doing a completely clean reinstall (options a & b are downloadable PDF files):

a) Completely Clean Win10 (Re)install Using MCT to Download Win10 ISO File

b) Completely Clean Win10 (Re)install Using MCT to Create a Bootable USB Drive

c) How to do a CLEAN Installation of Windows 10 (Tom’s Hardware Forums, with screen shots)

I never choose the “thermonuclear option,” the completely clean reinstall, until it's clear that this is the only viable option. I hate having to go through all the work of reconfiguring a machine from scratch if that can reasonably and safely be avoided.

Thank you for the reply. Will report back. I have not noticed any performance issues whatsoever yet. Just the failing update.
