Hey thank you for getting back to me,
When you run the command DISM /Online /Cleanup-Image /RestoreHealth, DISM attempts to repair corrupted system files by downloading clean copies from Windows Update. If your PC can’t access Windows Update or the corruption is too severe, DISM needs a local source, such as the Windows installation files, to pull the correct files from. That’s where the /Source argument comes in it tells DISM where to find those clean files. For example you might use a command like:
DISM /Online /Cleanup-Image /RestoreHealth /Source:D:\Sources\install.wim /LimitAccess
In this example D:\Sources\install.wim is the path to the Windows image file usually found on a USB drive or ISO. The /LimitAccess option prevents DISM from using Windows Update and forces it to use your specified source.
To get this repair source you’ll need to download the latest Windows 11 ISO from Microsoft’s official site, mount the ISO by right-clicking and selecting “Mount” then locate the install.wim or install.esd file inside the Sources folder sue that path in the DISM command.
If DISM still fails the most reliable fix when corruption is widespread is to perform an in-place upgrade repair. This involves downloading the Windows 11 ISO or using the Media Creation Tool running setup.exe from the mounted ISO, choosing “Upgrade this PC now” and selecting the option to keep personal files and apps. This process reinstalls Windows without deleting your files or programs.
Since you mentioned the error affects most apps like Photoshop, NVIDIA Broadcast and Focusrite Control it’s likely system-wide corruption in that case the in-place upgrade repair is your best option.
Best regards,
Marcelo
