Source to use for DISM on Windows 10

This is not completely true. The suggestion is to download the Techbench version and use DISM to apply to install.wim directly. However, you can also use the version download from MCT except it will involve an extra step as follows:

1. Use the latest version of 7-Zip to extract the content of install.esd. For example: to a folder xxx on the desktop
2. From Admin command prompt:
   Dism /Online /Cleanup-Image /RestoreHealth /Source:%USERPROFILE%\Desktop\xxx\windows /LimitAccess

See screen shot, the contents of install.wim and install.esd are exactly the same.

 

DISM offline source

Hi,

Thank you for your reply.

Just to be clear, I'm not trying to do a repair install, just a DISM using a known good source without the use of a network or Windows Update.

So basically:
- boot the good system to recovery mode off a flash drive,
- run DISM to copy the good image to another flash drive,
- and then run DISM on the bad system, pointing to the good image on the flash drive with the /source switch.

And this will do nothing else to the good system other than run the DISM against a known good offline source? It's not going to install stuff or do a repair install or anything like that?

Sounds like a plan.

Thanks again!

Hello @dbdan22,

You are talking about repairing a Windows Image, either Offline or Online.

[1] You might find these useful for the different DISM commands and what they perform . . .

[2] The above is referring to performing an In-Place-Upgrade - Repair Install. Here is a brief overview that I have put together . . .

In-Place-Upgrade - Repair Install
Information & Tutorials:
This is a Non-Destructive Process which keeps ALL your Apps, Programs, and Personal Data etc Intact . . .

IMPORTANT: This is an extract from the Tutorial below . . .

> How to Do a Repair Install of Windows 10 with an In-place Upgrade

Basically . . .

[1] Download the ISO to the Desktop.
[2] Right-click the ISO > Mount.
[3] Open File Explorer.
[4] Double-click the Mounted Drive to open it.
[5] Double-click setup.exe.
[6] Choose the Upgrade option.
[7] Select Change what to keep.
[8] Select One of the following . . .

• Keep Personal Files and Apps.
• Keep Personal Files Only.
• Nothing.

[9] Unmount the ISO by right-clicking the Mounted Drive > Eject.

The only downside is that you could POSSIBLY lose some of your personalizations.

Recommendations:
DISABLE:

ANY Non-Microsoft . . .

• Antivirus Software.
• Firewall software.
• Drive Encryption Software.

I hope this helps.
