After installing the latest round of important Windows Updates, running DISM /Online /Cleanup-Image /RestoreHealth no longer works. Rather, It returns Error 800f081f and the following message:
The source files could not be found.
Use the “source” option to specify the location of the files that are required to restore the feature. For more information on specifying a source location, see Configure a Windows Repair Source.The DISM log file can be found at C:\Windows\Logs\DISM\dism.log
I have run System Restore and, after doing so, the DISM instruction runs properly and returns the message that it has run successfully and repaired the corrupted components. However, running Windows Update again followed by running DISM reproduces the problem reported above.
Any help in resolving this issue would be greatly appreciated. I should add that I do not have an original Microsoft Windows 8 DVD as my version of Windows 8 Pro (64bit) - now updated to Windows 8.1 Pro - is Dell's OEM version.
