Using the DISM Command Prompt Tool to Repair Windows

⚛️ DISM is a tool included with Windows that can repair some types of Windows corruption.

⚛️ The DISM Command Prompt tool
DISM is a tool for Windows repair that lies between the System File Checker (SFC) and a full Windows reinstall in power. It is run in an administrative Command Prompt in three steps:
- DISM /Online /Cleanup-Image /CheckHealth
- DISM /Online /Cleanup-Image /ScanHealth
- DISM /Online /Cleanup-Image /RestoreHealth
Running DISM is safe even on healthy systems and can stabilize Windows if problems are detected.

What comes to mind after watching this is to go back and re-learn how to write batch files like we did with DOS and put them on the desktop to be run regularly. Thanks once again Leo.

The quickest and surest (although still not bound to work) way to fix corruption is to first run:
dism /online /cleanup-image /restorehealth
Then run:
sfc /scannow
Often if you run sfc first it cannot repair files but is almost bound to if you successfully run the aforementioned dism command.
Thanks for great, very well explained content Leo.

Great video!

What I would suggest is after RestoreHeath, just one more scan I'd recommend doing the "SFC /scannow"
(How I was taught the SFC /scannow after the DISM scans)
Just to be sure everything is done well.

Till next time!

Hey, Leo! Thanks! In this day and age it's great to practice a little self help those old DOS Commands

[JarkkoLaitinen]

A good and informative video 🙂👍 Thank`s

Hi Leo!! Will this procedure work with Windows 10 ENTERPRISE? Or, does it not matter what version of Windows 10 you are using? The commands are the same??

[Knards]

I run restorehealth/SFC every Sunday, whether It's raining or not

Hi Leo, got any suggestions for when Windows Update service goes belly up? Typical scenario I encounter is individual KBs install fine, but at some point Windows will just keep failing on any Cumulative update. Eventually it will become so far behind everything just stars falling apart. I've tried numerous variations of rebuilding Windows update services, & using Windows install media to attempt a repair has never been useful for me in environments where encryption is in play; just never succeeds. I hate having to reimage machines that shouldn't need it, feels like concession of failure 😅

Hi Leo

When I have any serious issues with my Windows 10 setup I normally try the following.
SFC /SCANNOW
DISM (as per this video)

Then if still not working correctly.
System Restore

Last resort option
Inline Reinstall of Windows 10

The last one has helped me out of a whole lot of problems in the past. Any chance of doing a video on this option, as I think it could be really useful for some of your viewers? The advantage of this is you don't lose any files or installed applications.

I'm aware there are caveats, mainly Windows needs to be able to be launched in order to do this option, and a copy of Media Creation Tool will be required.
I make a point of creating an image file using this tool after every major Windows update just in case.

Seems sort of extra. If I suspect any problem I immediately get my backup disk and do a clone restore. Takes about 10 minutes but the whole system is back to clean.

Hi Leo, enjoy your videos as they are informative and easy to understand and follow. I'm asking if what you explained in this video would resolve a Windows Update problem I am having with the recent Windows Cumulative update May 14, 2024 WIndows 10 Version 22H2 for x64based system —KB5037768, in which I receive the following error message after 100% install - Failed to install on ‎19/‎05/‎2024 - 0x800f0905.

I have Windows 10 Home. I have used Troubleshooter for WIndows Update which did not resolve the problem. It is now the 5th time it has failed to install since May 15, 3 times it has run automatically (Auto Windows Update turned off) and I have run it manually twice. As it is an automatic update it will continually try and update without my prompting. Any guidance would be appreciated.

How often do you find that DISM or SFC actually fixes the problem? As a person in IT responsible for dozens of machines at work and otherwise my success rate with either of these have been very very low.

[UltraZelda]

I prefer to use a Debian installation disc image to "repair" Windows. Works quite well in my experience.

[gwine]

One comment, it is not necessary to use mixed case in the commands.

[petersack]

GOOD ONE ! JUST WHAT THE commom person, needs TO deal with this

[wallychambe]

Seems like I have to use it to fix my computer after every other windows crappy update, it find corrupt files!😱😱

[jalpa]

Back in the late 70's early 80's my venture w/windows began w/Windows 3.11 For Workgroups. From then until now w/windows 10 it has been nothing but 1 constant hassle.... which is why I gave it up 10 years ago and went w/Linux-Debian. Linux says one can run windows apps on Linux Wine, Play on Linux, and a couple I do not find that true at all.... So, at times, I still run Windows 7 64-bit....! =)

[jtc]

Definitely NOT into WIN 11 ! having to use WIN 10 because my old and BE-LOVE-ED WIN 7 machine started going down the hatch! Can PLEASE do a vid on WIN 10 and DISM??? If you have already done so, pls show link?? Thank You!
