Unable to use In-place upgrade for Windows 10 repair

I am currently using Windows 10 Pro v 1909 Build 18363.418 and it has become a little bit glitchy and slow running. I would like to repair my operating system using the In-place Upgrade action.

I am trying to use an ISO of the same version and build however when I mount the ISO and am presented with the options to save my current files and folders, etc., I am only presented with the option that nothing will be saved - the first two options being greyed out.

It is my understanding that I should be able to use this same ISO to repair my system (or am I mistaken?) yet I am undable to do so.

Can someone please help me out with this conundrum?

Thanks, N.

Thank you Paul Black for your response to my query. I did just what you suggested in your response - mounted the ISO and selected and clicked on Setup. The first few steps went smoothly (I chose not to include updates at this time and waited to be presented with the list of options to save programs and files, etc. That is when I was presented with only one option - Nothing would be saved. Strange but nevertheless true.

Thank you dalchina for your response to my query as well. I have taken the time to check that my hard drive is sound. All good there. I have double checked my ISO for major build, "bitness" and language. All are the same as my current, slightly buggy installation.

I downloaded the ISO from Techbench by WZT, and another from Heidoc. Both identical versions and builds. In fact, I used one of these ISOs to setup the current Windows 10 Pro system on my PC. Just cannot remember which one I used. However, both give me the same result as I stated in my original post - no ability to save programs and files - only clean install.

The reason I wanted to use this ISO is because it is what I currently have and up until recently, it was working fine. My network works fine with it and it seemed the easiest way to repair my operating system without any "upgrade issues" for drivers, network interoperability, etc. Looks like I was mistaken...

Thanks again for your post. N.

Hello Ghot... Thanks for your reply. You are correct, v 1909 is long in the tooth. I get your point..lol but if it works, don't change it...lol

Ghot... Thank you for your follow-up message (I see you figured out my anagramme). All the computers in my home are the same version - v 1909 Build18363.418. An In-place-Upgrade was what I was trying to do to repair my existing to be the same. I was trying to avoid using anything different in the mix

I had also wondered if the issue was that the ISO was a version that was "too old" and that prevented it from being repaired using the In-place Upgrade method.
