    Found an old iso with W10 21H2 and wondered can I update it easily?


    Evening

    I have a packaged iso which I could use do to a clean install BUT...

    I am fairly sure it has 21H2 on it. Is there a way to check?

    It is an iso I have somehow built which includes some of my other software pre-installed and presumably activated.

    I am probably going to have to spend hours trawling through my previous posts to see if I updated what I was doing as I went along just in case I needed to come back to it and refresh my memory.

    Can't even recall what software I would have used. I know I was playing with SimPLix at some point but don't think I ever succeeded in doing what I wanted to so I probably used MagicBurn or something.

    Is there a way to find out easily which programme created the iso?

    look at the properties with an iso handler - if you dont already have an iso handler anyburn free version will do

    extract the install.wim and query it - or mount the iso and query the install.wim with wimlib or dism or similar

    Further to the above I found this for you > See Full Details about a Windows 10 ISO file or USB

    Also, have a look at the Related Tutorials at the BOTTOM of the above Tutorial [ there are a few ], as they may also be related.

    I hope this helps.

    Is the iso extracted to a USB drive or it's just a single iso file?

    The Win 10 21h2 is almost 2 years old.
    Why don't you built a Win 10 22h2 USB drive or download a Win 10 22h2 iso file using MCT ?

    OK. Only just got back to this.

    Anyburn suggested by SIW2 wouldn't give me any application information. I do have ImgBurn installed on this PC so I assume it was that that wrote the iso.

    Not been able to query the install.wim as yet but will drop onto that in a moment using Paul Black's info he posted.

    In reply to MegaHertz, it is a single .iso file stored within a folder on a USB drive so it wouldn't need burning to a DVD (and it's probably too big for that at 9.8Gb) or will need extracting to a clean formatted USB of suitable size.

    I do want 22H2 but I have other programmes within this ISO which is why it is 9.8Gb. I built it originally to be able to do a fast clean install of the mainstay applications I use to minimise downtime if the worst happened.

    That was fun. Couldn't open elevated cmd prompt.

    Anyway, I'm in there now. Not sure DISM command will work when you have this as a path?

    Even tried copying Test.iso to D:\ but I have not got enough disk space! My root drive only has 11.6Gb left also so not sure I want to fill that anymore. Although I have not started that process...

    Will try this now as couldn't get DISM to work. I'm not readily familiar with manipulating iso

    one way might be to apply the wim to a spare partition, boot into it, update/upgrade install to 22h2 and then capture the partition into a new install.wim.

    I think my memory has burnt out. About 10 minutes ago, I readily stumbled upon that window in ImgBurn.

    Can I find it now? NO!

    I'm not entirely sure why I have so many different Windows iso on one USB. I think it was to save them as a repository in one place.

    But now I have to read up on how to do what you are telling me to do. It's all good fun especially when you're stressed and anxious about it.
