Win. 10 Repair/Replace Corrupted Files
BretMan:
Hell everyone, Just joined.
I tried the All-In-One, twice, and it didn't solve my problem. I've searched the forum and see a couple related posts but being an intermediate user I want to ask first so I don't make things worse.
A brief summary: Several months ago I upgraded from Win. 7 Ultimate (64) to Win. 10 Pro and everything was ok. About two months ago some crashes unltimately indicated that my local HDD was failing which was confirmed by Hard Drive Sentinel afterwards. I then cloned my local drive with AOMEI Backupper to a new HDD of the same WD make and model and total disaster was avoided. However, the failing HDD developed 10 bad sectors of which a couple were non repairable and this apparently corrupted some system code. Since the cloning, every attempt to update my v1511 to cummulative update v1604 fails, error: 0x80073712. SFC /scannow scans result with "... some corrupt files could not be fixed...". I've separated my data files off my local drive to a separate external backup drive to make more free space, now at about 150GB. I've also tried repair-installs from disk and also fro local virtual HDD and at 33% completion they always fail. Fortunately, my system runs ok generally and most software can be installed. Sometimes it crashes to the blue screen but always reboots ok. Although it fails to update the OS, the security updates do seem to be updating ok.
The only fix I can think of at this point, with my limited knowledge, is to provide this forum with the SFC scan log showing the corrupted files. Then you identify which ones need replacing so at least the update or repair-install will complete. I have no idea how to replace system files so I'd need your instructions. Or maybe there's a simpler fix you may know about?
Many thanks.

Hi and welcome to the forum.
From within Windows can you press and hold F2 throughout a Restart until the BIOS appears.
Use the cursor keys to navigate to Boot.
Use the cursor keys to highlight the ODD (DVD drive) and use F5 or F6 to move it to the top.
Insert the install disk - press F10 to Save and Exit and confirm.
After the restart press any key to boot from CD/DVD when prompted.
Use the dropdown to change/confirm the Time and currency format - Next - then click on Repair your computer.
Click on Troubleshoot - Command Prompt
Type bcdedit |find "osdevice" then press enter.
At the next prompt type the following command where X=the partition letter
sfc /scannow /offbootdir=X:\ /offwindir=X:\Windows
This will take a while to complete but will check and repair any file corruption from the incorrupt source of the install disk.
For clarity, that is a Pipe symbol before find in the bcdedit cmd and is the uppercase of \ and there is a space before each /
When the scan has completed, type exit and press enter to close the cmd window - remove the install disk and select Shutdown.
Boot up then go to Settings/Update & Security to run a manual check for updates.
You may still not get the 1607 update - some are still waiting for that normally through Windows Update, but with a later install disk, you will be able to update by doing a repair install with that disk.
If you are using a 3rd party antivirus program, then it is advisable to disable it before performing the repair install.
You can get the latest disk by clicking on the Download tool now button in https://www.microsoft.com/en-gb/software-download/windows10 or hit the Update now button.
If you use the disk method, then opt not to look for updates and then you can do a manual check for updates after the upgrade.
You may also get that option when using the Upgrade now method.

Thanks Boggin. I want to be sure I do this right so let me ask you for some clarifications. My C: drive is my local drive which has the corrupted system files and my D: drive is my DVD drive, which is where I will be inserting any disks for this repair.
1- The "install disk" you refer to is the "Win 10 RepairInstall with an In-Place Upgrade" disk which I created by burning the file I downloaded from Microsoft, correct?
2- You said to "... change/confirm the Time and currency format...". I don't get this. It sounds like I'm buying something. Please explain about the currency.
3- By the command prompt, you mean the Command Prompt (Admin)?
4- Here are the two lines you said to enter in the command prompt window. I've written them as per my system with an underscore (_) to represent a blank space and I will enter them exactly as shown here. Please let me know if I have them written correctly:
bcdedit_|find_"osdevice"
sfc_/scannow_/offbootdir=D:\_/offwindir=D:\Windows
5- You stated "You can get the latest disk by clicking on the Download tool now button in https://www.microsoft.com/en-gb/software-download/windows10 or hit the Update now button." This is the same disk previously mentioned in 1- above?

1. - Correct
2. - There's a dropdown which defaults to the US - as I'm in the UK, I use the dropdown to select United Kingdom - you aren't buying anything.
3. - No. - It's just listed as the Command Prompt which has admin privileges outside of Windows.
4. - That is how you enter those cmds - you need to enter the bcdedit cmd because it doesn't always see the volume as being in C: so you use whichever partition letter that cmd returns.
So if the cmd returns C then you use C on both sides of the cmd - if it returns D then you use D on both sides of the cmd.
5. - Yes, but it would depend when you created an install disk - if it was prior to August last year then it will have been for version 1511.
The current ISO is for 1607 14393.0 so it includes the August updated version.
Does this clarify and answer your questions ?
BretMan:
For some reason I didn't get the notification about your reply. When I went to the site just now I had to go through a process to confirm I'm not a robot and once in, the notifications show that they are set to be sent to me. (???)
I think the steps are pretty clear now. I'll do a backup tonight then give them a try over the weekend and report afterwards. I really hope they work.
