    This sounds great. Do I unzip the Explorer++ program files into the main directory of my Recovery USB, or can I create a New Folder?
    Yes, unzip it. Zipping is just used as a means of easing downloads.
    Stick it in a folder of its own.

    In either case, what do I need to type in CMD to launch Explorer++?
    Use the Command prompt to browse to the folder you've stuck it in then enter the command
    Code:
    Explorer++.exe
    because that is the name of the unzipped file.

    I've never bothered learning about what I can do with its configuration file [.xml]. It's just a file that appears in the folder after first using the tool. The .xml can be viewed in Notepad if you want to take a look later on.

    Do note that the OS that runs when you've booted from a USB is not Windows, it is an independent OS. It uses whatever it wants as the drive letters of disks/drives so it can take a while sorting out which is which***. I give each disk/drive a unique name [label] to help me identify them. More info in para 2.3 of Use InstallUSB Notepad as a rudimentary File explorer to backup files [post #33] - TenForums

    *** The drive letters it uses do not affect what they are when you later return to Windows. They will once again be whatever they were before.

    All the best,

    Otherwise I'll try the "custom" install option using the recovery USB, but I don't know if that will work since I don't currently have the required 10GB disk space to proceed. Plan to delete some files using CMD after I back-up, but of course this adds complexity and risks...


    Please post a link indicating the need for only 10 GB free space.

    Substantially more free space is often needed.


    If both reset save files and custom install fail then consider backing up files followed by renaming registry hives.

    If renaming registry hives fails then perform a clean install.

    A couple of years ago, a good friend did the same thing...powered down his slow computer after 6-7 hours of continuous Windows update activity.

    I tried everything in the book and not in the book as a techie. All of the methods listed above failed. I spent at least 2 full days (I'm retired) trying to get it running again. In the end, I considered Windows 10 to be 'toast' on his dual processor computer.

    My ONLY soulution was to first remove the drive and copy all his documents and other files (including a massive 3TB video library legitimately downloaded from some retailer) to temporary drives I have and then install a brand new, shrinkwrapped legitimate copy of Windows 10 I had laying around and then updating the daylights of it (more than a days' worth!) and then putting all his data files back. He still has that antique computer!

    Thanks everyone, here's the latest status:

    1) I used Macrium to create an image back-up of my files.

    2) I used WinPE to explore my computer and free up 70GB of disk space.

    Next step is to actually repair or clean install...

    I tried Repair Upgrade with my Recovery USB, but it says:
    "Upgrade option isn't available if you start your computer using Windows Installation media."

    So my new question, is there a way I can upgrade or repair using WinPE explorer then? It's definitely the Windows system files or registry that were corrupted during the failed auto-update, since all my personal files are still intact.

    Surely there is a way to update the system files only, i.e. replicating the process of a Windows update? Instead of the drastic option of a clean install, as I have lots of files and folder structure to manually recreate if so.

    I'm not sure, but the Custom Install option on the Recovery USB says I need to have 10GB space. Also my USB itself is just 8GB so the install couldn't be much larger?

    Is there any guide to renaming registry hives? Thanks

    Whilst you can use DISM to perform an offline repair, there is, frankly, no guarantee of getting your system back up and running given that it was interupted at an arbitrary point.

    You can't perform an 'in-place upgrade repair' unless you can boot normally.

    If you had a System Restore point available and this was applicable in your case, you could try launching System Restore by booting your PC from an Win 10 bootable disk, clicking 'Repair your computer' and on through the various blue screens. You would need your password for that. System Restore would of course attempt to restore your registry and system files to a consistent state.

    Remember- you got yourself into this difficulty by not having taken appropriate precautions.

    Consider: apart from the technical curiosity of trying to fix what you have now, how long would it take you to reinstall your programs and copy back your data?

    This is a Microsoft link on renaming registry hives for Windows 8 dated 09/2021:

    https://learn.microsoft.com/en-us/tr...ic-repair-fail

    https://www.makeuseof.com/fix-there-...in-windows-10/

    They are trial and error steps as there is no Ten Forums tutorial for Windows 10.



    If the renaming of registry hives fails then with 70 GB free space there may be another option before a clean install.

    Thanks, just realized I already tried the renaming registry hive to .001 in step 5 of my original post before. Thanks for reminding me about it, I undid the rename instead and now I can launch CMD from my laptop's own WinRE instead of the Recovery USB's WinRE.

    What is the final step you're suggesting? I can free up even more disk space if required, just stopped at 70GB cause I thought that's plenty.

    For a custom install:

    a) Files are saved to Windows.old

    b) A fresh versions of Windows 10 is installed

    c) Drivers need to be reinstalled

    d) Applications need to be reinstalled

    e) Important files are restored from Windows.old
