    I cannot update the existing installation, Windows setup says that I have to run windows first and run the setup from there. If I go on with the custom installation it will install a fresh copy and move the old installation to another folder.

    Again, Windows 10 is not my main OS so I could start afresh but is there a way to troubleshoot and see what's wrong with that? Why cannot I see the boot log file?

    Thank you for all your help so far.
    Assuming you have the ISO file, either on DVD or on external drive, try the following.

    Mount the ISO while running under existing OS (10061?). Run (NOT boot) the SETUP.exe file. Choose the top first option. It will do what's called an "In-Place" upgrade, which will retain all your apps and progs, and most of your settings. Takes about 1 to 1.5 hrs, depending on your config.

    Unfortunately I cannot access the OS, the PC reboots while booting up.
    Or maybe you meant to run the command prompt and run setup.exe manually?

    In most versions of Windows, if you run a Refresh it'll put a folder on the desktop with a list of the apps that it removed.
    Is there any way you can gather any information? In particular, I'd like to look at the following reports to see if there's any information there:

    First, Please provide this information (even though you're not reporting BSOD's) so we can provide a complete analysis (from the Pinned Topic at the top of the forum): Solved BSOD - Posting Instructions - Windows 10 Forums

    Next, please generate this report:
    Please do the following:
    - open Event Viewer (run eventvwr.msc from the "Run" dialog)
    - expand the Custom Views category (left click on the > next to the words "Custom Views")
    - right click on Administrative Events
    - select "Save all Events in Custom View as..."
    - save the file as Admin.evtx
    - zip up the file (right click on it, select "Send to", select "Compressed (zipped) folder")
    - upload it with your next post (if it's too big, then upload it to a free file-hosting service and post a link here).

    Missed your last post.

    Can you access the files from the Win10 installation?
    If so, you may be able to see the folder on the Desktop for the apps that were removed.

    Look in the Windows\Minidump directory of the Win10 installation to see if there are any memory dumps in there.

    EDIT: Event Viewer logs are located in Windows\System32\winevt\Logs\
    copy and zip up the Application and System logfiles (they end in .evtx), then upload them here also

    Hi all,

    any help? I could reinstall but I'd like to fix the existing installation - mostly as an exercise. Any help appreciated.

    Hi, just as a follow up my system has come back to life. How? Not sure.

    First I went on the Drivers folder, added the 'last accessed' column. Only two files were marked as accessed back in April (which was approx the last time Windows 10 worked). I took ownership of the folder and renamed them.
    Rebooted in windows 10, now windows wouldn't boot up at all, it would go straight into automatic repair mode. I tried again safe mode, no luck.
    Final test, went back to windows 10 folder, restored the extension to those two files.

    Rebooted and here I am!

    Ah, when I rebooted into windows 7 windows asked if I wanted to do an integrity check on the windows 10 disk. I could not skip it (my keyboard sometimes failes to work at boot) and the procedure found several errors on several files.

    When W10 restarted it said "configuring upgrades", which tells me that last time windows 10 worked I upgraded something!

    BTW the two files were clfs.sys and http.sys. How bizarre, despite it's booted up now, those two files are still the ones accessed last, in April...

    I've now managed to install the latest build - which fixed my start menu not working anymore BTW.

    Well, hope it lasts. Thanks for your help, I appreciated it!
