Windows 10: Error message after attempting to export registry

I was about to make a change my Windows 10 registry, so I went to create a full backup copy first. When I do this, I get the following message after the process completes:





I get the same result on both my SSD and my regular hard drive, so it's not a problem with drive A 95.22 MB file resulted in both instances, and looking at it with Notepad it appears to be okay, but of course I cannot assume that. My web searches on this only turned up a single related item, which had no suggestion other than to run chkdsk, which is unwarranted in this instance.

Windows Update Error Message 0x80070543


Ya Ya Ya, there's over a hundred threads like this, ...

Anyway, started getting this error message a few days ago, and done a lot of searching on this error message, apparently it's not, uncommon.

In particular, the (currently) 4 updates that are being affected are:

• Update for Windows 10 Version 1511 (KB3173428) - Error 0x80070543
• Security Update for Windows 10 Version 1511 (KB3172729) - Error 0x80070543
• Security Update for Adobe Flash Player for Windows 10 Version 1511 (KB3174060) - Error 0x80070543
• Cumulative Update for Windows 10 Version 1511 (KB3176493) - Error 0x80070543

The actions I've taken to date are:

1. Uninstalled firewall program (comodo)
2. Uninstalled anti-virus (Avast)
3. Reset the windows update catalog on local machine.

So the above errors are with the above done.

What other steps should I be taking to resolve the issue?

Below is notations for when I actually add to this thread.

1. Attempted to use the troubleshooter, no dice.

 

BSOD - Registry Error

Your BSOD code is 0X000000051

Here's the Google search I did for it: https://www.google.com/search?q=0x0...j5.399j0j7&sourceid=chrome&es_sm=122&ie=UTF-8

There is a hotfix available that might help, https://support.microsoft.com/en-us/kb/810558

This thread makes a few good suggestions too: http://www.sevenforums.com/bsod-hel...dows-7-pro-sp1-registry-error-0x00000051.html

+1 to listing your full system specs, OS version, etc. I did only look at your BSOD log file.

Run a Diskchk /R (I know you already ran one, so you can skip this)

Run SFC /SCANNOW

Report back.

 

Error Message when updating from Win-7 to Won-10

Bree
I followed your suggestions (2nd Aug 19) for installing Win-10. Made the bootable flash drive successfully through the media creation tool. But when I attempted to upgrade and activate to Win-10 (64 bit) from within Win-7 (Pro-32 bit), I got the following error message:

Error # OxC1900101-Ox20017. " The installation failed in the SAFE_OS phase with an error during BOOT operation"

I read the diagnostics under this error number and carried out the proposed fixes, i.e. update Win-7, uninstall Malwarebyte antivirus, disconnect all external hardware, e.g. printer, scanner, external hard drives. I then tried to repeat the steps to do the upgrade through the Win-10 bootable flash drive as before. Got the same error message.
Appreciate any further comments and suggestions as to (a) what does a failure in the SAFE_OS during boot operation mean, (b) what can I do to solve it. Is this anything to do with the hardware in my computer? I listed these in my first posting above.
Thanks for any help
