DISM.exe repair source to windows update

[Stellar Ray]

Hello,

What is the command line for setting Windows Update as DISM.exe repair source?

This? - DISM.exe /Online /Cleanup-Image /RestoreHealth /Source / WindowsUpdate 

[Robchil]

you create a new boot cd with windows install media creation tool. and use the .wim on that i guess as source if you want to use a fresher media.

remember to run sfc /scannow after you restore health.

DISM.exe /Online /Cleanup-image /Restorehealth

Important: When you run this command, DISM uses Windows Update to provide the files that are required to fix corruptions. However, if your Windows Update client is already broken, use a running Windows installation as the repair source, or use a Windows side-by-side folder from a network share or from a removable media, such as the Windows DVD, as the source of the files. To do this, run the following command instead:

 

DISM.exe /Online /Cleanup-Image /RestoreHealth /Source:C:\RepairSource\Windows /LimitAccess

Note: Replace the C:\RepairSource\Windows placeholder with the location of your repair source. For more information about using the DISM tool to repair Windows, reference Repair a Windows Image.

I already have windows 10 installation media on USB, a different version or OS build than the current one using, but I get return msg, 'The source files could not be found' after scan.

According to the link, in the Fix Windows 10 image recovery, the command line is the following - DISM /Online /Cleanup-Image /RestoreHealth /Source:D:\Sources\install.wim

And instructed to replace 'D' with the corresponding ISO mount, so I changed it according to the USB drive letter.

What did I miss?

so if you go to D:\source and type dir *.wim it lists your wim?

Via list partition in the command prompt? 

Drive D doesn't have any windows installed, nor USB install media has D letter. How & why D could be the source? Here D is a command function?

How do I list wim?

that's why you usually just run the commands in an adminmode dosbox while troubleshooting, booting from the USB or DVD..

So, I went to Update & security>recovery>advanced startup>troubleshoot>advanced option>command prompt

It says error 50, DISM doesnt support online... something like this.

The command line was exactly - DISM /Online /Cleanup-Image /RestoreHealth /Source:G:\Sources\Install.wim

Tried DISM.exe without ' /online', returns error 84.

hey.. i'm MCSE, but that just means Must consult someone else.. ..

 

you run dsim toward a mounted iso image, to update it, or the drive you have the boot usb in.  to repair older images, like from an installation image created through system center config manager or other auto install programs.  but you should use the rest of the commands to be sure it's the right file, and if it is writable. 

If you use it without source you check your current windows install's wim file.

Dism /Online /Cleanup-Image /RestoreHealth attempts to fix corrupted system files from Windows Update therefore internet access is required. If you ever encounter problems, you should run sfc /scannow first and if it doesn't succeed, then run Dism /Online /Cleanup-Image /RestoreHealth.

I've always been able to use it from a running install, just make sure to open an admin command prompt and not a user one.

 

I've had cases where an sfc /scannow reported stuff it wasn't able to fix, but after the above it was corrected.
