    Just wondering,- I made an image of the current system,-it used 5 dvd's, about 64 gigs.
    The Win 10 iso-file I downloaded used only 1 dvd when I burned it.
    How can that be?

    You probably have programs installed, but it also uses different compression.

    If you can, use an external HDD rather that DVDs for the image, much faster to save/restore the image.

    The ISO contains the source files in compressed format, so it will be much smaller.

    The image is everything on your PC. Windows 10 says 20GB needed for installing. Adding in other programs and software, including preinstalled HP stuff, along with a hibernation file the size of your RAM and a page file. It adds up fast.

    In another mind boggler, how is it a Windows 10 dvd/usb is 4GB but when installed is 20+ GB. I know the files are compressed and what not, but wow LOL.

    That makes sense. I've got Office too . . .
    That's some serious compression on that single DVD.

    My external HDD died silently in bed the other day.

    The systems vary with use, Mine is currently 103 GB but that includes 32GB for a Hibernation file, a full install of Office 2016 Pro, Photoshop & Lightroom and a shed load of other Pro Software

    AS soon as a system runs for the first time all the system variables take effect and temp locations are populated system logs are built the registry is filled in which causes more space usage, and you have to remember that installs do not run just from the install media but form the internet to collect drivers and required modules for the hardware

    I never back up. It is a waste of time, and disk space for me. If I did back up, I would make multiple copies, and buy GBs in the cloud also. Even if the hard drive died, it would still be in the cloud.

    No, I wrote a little program which does everything I need. Actually two programs. One modifies the install.wim, the other I run after first boot, and all my programs are installed. All my important stuff I keep on separate drives, and in the cloud so there is no need to waste space backing up.

    Nope. I have everything I need to save, really save in the cloud, and on other disks. I am booting like, at least 4 different OSes right now, so I can boot into any one of them. I really don't see any point in creating an image of something that I can install in a few minutes.
