DISM-GUI is a free app for Windows 10 and 11 that gives you access to various commands to check and repair Windows.
Good to know: DISM stands for Deployment Image Servicing and Management. It is a command line tool that, among other features, may be used to find and repair Windows issues related to missing or changed operating system files.
The free app makes the functionality more accessible. You still need to know the basics, as the program lacks documentation. The program interface consists of buttons that run the selected commands in a command prompt window.
It includes all popular options, including cleanup, which frees up storage space by removing overhead from the component store, and restore, which attempts to repair the Windows system.
Tip: check out Super God Mode as well. It creates shortcuts to more than a thousand admin tools and settings on Windows.
Here is a quick overview:
- Check (CheckHealth) – The command checks for corruptions inside the Windows image.
- Scan (ScanHealth) – The command runs a more thorough scan.
- Restore (RestoreHealth) – Searches for errors and attempts to repair them.
- Online – check using the local image.
- Wim – use an ISO image or an unpacked ISO image for the repair.
- ESD – use an ESD image.
- Analyze ( AnalyzeComponentStore) – Checks the component store for overhead.
- Cleanup (StartComponentCleanup) – Cleans up the component store to free up disk space.
DISM-GUI supports several non-DISM commands next to that:
- SFC Scan — Runs the command sfc /scannow.
- CAB Install — Install a CAB update on the system.
- ESD > WIM — Convert an ESD file to a WIM file.
- Get State — Returns the state of Reserved Storage.
- Enable / Disable — Enable or disable Reserved Storage.
Note: Windows reserves storage on the primary partition for “proper performance” and updates.
Commands are executed in a command prompt window in the background.

Verdict
DISM-Gui is a useful helper app for Windows 10 and 11. It is especially useful for admins who use the commands regularly and for inexperienced users who need to run the commands.
All in all, it is a useful free app for Windows administrators.
A screenshot or at least a description of the output after clicking one of the buttons, would be useful.
Does it open a window to display the results? If yes what type of window?
I would normally run that that stuff in an admin command prompt.
You are right. The app launches a command prompt window and runs the commands from there. I have added a screenshot to highlight this.
I would assume there’s a UAC prompt when it first tries to open the admin command prompt?
It opens an UAC prompt on start.
