You haven't said what the file scans reported.
Is this where you tried the manual update to the Creators Update and did you create a bootable install disk or are you able to create a bootable install disk ?
https://www.microsoft.com/en-gb/software-download/windows10As it won't update and if you don't have a 1607 install disk, then you can create one for 1607 from
http://windowsiso.net/ and use Windows USB/DVD Burner Tool to create a bootable disk.
http://wudt.codeplex.com/At the ISO site hover over Win 10 in the menu bar then hover over 1607 and select Standard, saving the download and then use the Windows burner tool to point it to the ISO.
Now we need to change the Boot order.
From an admin cmd prompt enter bcdedit and under Windows Boot Loader make a note of the Identifier - it can be either {current} or {default}
Enter this cmd to give you the old F keys you can tap as you switch on.
bcdedit /set {your Identifier} bootmenupolicy legacy
exit
Then shutdown and tap the key for Setup which could be F2
When you get into the BIOS use the cursor keys to navigate to Boot and use the cursor keys to select the DVD drive - F5 or F6 will move that to the top.
Insert the install disk then press F10 to Save and Exit - YES and when it boots up, press any key to boot from CD/DVD when prompted.
Use the dropdown to change/confirm the Time and currency format - Next - then on the Install window click on Repair your computer bottom left.
Click on Troubleshoot and select Command Prompt
Enter bcdeit |find "osdevice" and using whichever partition letter, use that where I've used X and enter this cmd.
sfc /scannow /offbootdir=X:\ /offwindir=X:\Windows
exit
To close the cmd window when done, remove the disk then select Turn off your PC and reboot to see how it performs then.
For clarity that is a Pipe symbol before find and is the uppercase of \ and there's a space before each /
To revert to a normal boot menu policy if you wish, redo the bcdedit bootmenupolicy cmd again and use standard instead of legacy.
