    Pretty sure SIW is right compare the size of your current SYSTEM with the one in your Regback.

    outch! Just found this on docs.microsoft.com

    The system registry is no longer backed up to the RegBack folder starting in Windows 10 version 1803

    Sounds like a problem with the registry - most likely the system hive.

    Ideally you would retrieve previous good hives from a system image or a shadow copy or from windows/system32/config/regback

    Then you rename the hives in system32\config, for example rename sotware to software-orig and system to system-orig and so on.

    Now copy the hives from the regback folder into the config folder.

    Attachment 349359

    Attachment 349360

    not the 0kb ones obviously.

    If she doesnt have any of those, there is a convoluted workaround that can be tried.
    No files in the RegBack folder that I can see...?

    You could use any decent pe to look for the regback hives.

    I am pretty sure the system hive is the problem , I have come across it before.
    There doesn't seem to be anything in the Regback folder.....is there another way I can try and repair the hives?

    It is a bit laborious.

    Install the exact same edition on a different partition - enter the same username she already has.

    Now you have two different approaches.

    1. Do a comparison of the original installation and the new one.

    You are looking for knitting program files not just in program files folder, but also in programdata folder and her username folder - typically in users\herusername\appdata\roaming and users\herusername\appdata\local

    The original and new hives can be compared using something like regworkshop Registry Workshop | www.torchsoft.com . You would need to compare the user hive as well as those in system32\config - her knitting program could have entries in \Users\herusername\NTUSER.DAT

    And/Or

    2. Try and repair the original installation.

    Rename the original system hive, then copy the new one in. But you will need to set the os letter correctly using nt6repair and do a system hive comparison to check the userprofile and anything else that looks like it might be needed. Then make those changes in the new system hive you copied over.

    With a bit of luck it the original will then boot up.

    Damn, that is very labourious....guess the easiest route is to just back up her data and reinstall Windows

    I would at least do a search for any files related to her knitting program and copy them somewhere safe, and keep a copy of all the hives.

    You might able to find the relevant files and reg entries and integrate them into the new installation.

    Or just make a wim image of her os partition which you peruse later at your leisure.

    If you have the time, running chkdsk /r /f could reveal underlying problems on you HDD and also attempt to "recover" bad blocks. and may fix some file problems...

    Yes... Some 5 minutes jobs can end up in many days of "Computer Related Acute Sporadic Tremors".

    Yes, chkdsk /f /r was the first command I ran when I started working on it...it came back stating that there were no issues. I looked closely at the hard drive stats and it says it's still 'good' but there are some reallocated sectors on the drive. Also, with a 1.4Ghz CPU, it's pretty slow, so I'm going to do a SSD upgrade for her while I'm at it....newer drive with no reallocated sectors that way, and the SSD speed boost might help make up for the slow CPU a little bit.

    Also means I have her entire old hard drive as a backup for the time being...doing a fresh Win10 install now...

    You're kind of left with idea "Why MS stopped backup registry in RegBackup ???" And then Nearly all Hives I recovered from vss where corrupted so, I stopped using this solution long time ago and never went back to see if it works today.

    Now I use third party Backup / Registry protection / Imaging solutions... All the way... I use MS tools for deployment, but never for protection.

    Yeah....to be one of 'those guys', it's decisions like that which made me start using Linux Mint as my daily OS on my personal laptop. I still have a Win10 gaming PC I also use for higher-end stuff like video editing, but day to day, my current Lenovo Thinkpad runs Mint 20.2 MATE. I do computer repair on the side, but hate dealing with situations like this with Windows and then finding out MS changed something to make it HARDER to fix :/

    Also you think about her, and you tell yourself, why didn't it last... I had to replace my moms Computer at some point... She suffered atrociously from everything that was there the last 10 years and was "gone". the computer spend 2 months in intensive care then 1 year of periodic Physiotherapy to bring it at a satisfying workable state.

    And most of the time they suffer from Hardware failure. Because they never touch something that works. Lost many icons but never a driver.
