This time, we will introduce the cause and solution if you are unable to run the command "reagentc /enable" to enable WinRE in Windows 10/11 and receive the error message "REAGENTC.EXE: Windows RE image not found."
Causes and Solutions for "REAGENTC.EXE: Windows RE image not found"
Cause
The reason for the message "REAGENTC.EXE: Windows RE image not found" is that the Windows RE image (Winre.wim) has been deleted for some reason.
The "reagentc" command is not unusable; the Windows RE image (Winre.wim) cannot be found. Therefore, you can still run the "reagentc /disable" command to disable WinRE, which was originally enabled.
I also had the error "REAGENTC.EXE: Windows RE image not found" on one of my PCs, and I was able to resolve it using the method introduced here.
Solution
Extract the Windows RE image (Winre.wim) from the Windows 10/11 ISO file.
1. Download and run the "Media Creation Tool" from the official Microsoft website.
Once the page opens, click "Download Now."

4. Under "What do you want to do?", select "Create installation media (USB flash drive, DVD, or ISO file) for another PC" and click "Next."
5. The "Select Language, Architecture, and Edition" screen will appear, so simply click "Next."

12. Right-click on the ISO file you just downloaded > 7-zip > click "Open."
13.The contents of the ISO file will open, so open the "sources" folder and double-click "install.esd" to open it.
14. The "install.esd" folder will open, so open the folder that matches your PC edition.
