I couldn't repair/replace my laptop's corrupt files doing an sfc or dism scan and had to do a reset as I couldn't do a refresh. I thought my laptop was clean when I created my last system image, last month, but when it came to using the system image I realised there was corrupt files on there too so I had to do another reset.
What checks should I do before creating a system image? so I know that as well as there being no viruses there are no corrupt files either.
Check for errors in Event Viewer and do an sfc and dism scan?
