I recently recovered a hung up Windows 10 after I had inadvertently allowed Windows Update service to not be disabled. I then re-enabled it during the recovery process so that it would do some updating again - weird, every once in a while, my computer seems to get fouled up by updates, then I have to start over again, but I seem to be able to recover it ok. Perhaps I interfered with some update and that's why it got screwed up.
So anyway, my computer is perfectly stable now, and everything works ok.
So I downloaded the 3.6/3.7 GB .iso and burnt it to a CD. I did this using WIndows Media Creation tool. I decided to add Windows Setup (Windows Media Creation tool = same thing) to my list of allowed apps in the firewall - not sure this is necessary, I just did it anyway. It takes a long time to get past 0% since it's a large file - each percent is like 300MB. But that went fine so now I have my DVD with Windows 10. I assume that this is bootable. So I assume I do not need a recovery or rescue disk or should I make one of those? Just wondering, if a bootable Windows 10 DVD is as good as a rescue/recovery.
So I've also made some restore points using the Control Panel and whatever how I did that - no problem there. I have a couple of those I can roll back to.
And I've chosen NOT to use Windows Disk Image in File History - the reason is that I only have a C: drive, no other drive to back up to. Perhaps I should invest in an external drive? I"ve always been hesitant to use Windows's backups since I wonder about file-locks. Do they unlock ALL files, do I really get a full and exact image? I guess Images have advantages (speed) and disadvantages (less flexibility).
So I re-enabled Windows update during all those boots where I get the messages like: PROCESS_INITIALIZATION_FAILED, CRITICAL_SERVICE_FAILED, Preparing Automatic Repair, Repairing Disk Error (I doubt there are any), This might take over an hour to complete (not really), 0xc000021a - seen that one?, Attempting repairs, CRITICAL_PROCESS_DIED, Diagnosing, CM_Get_Next_Res_Des - now this last one means you've got problems - your Control Panel device enumerator will not run - better leave Windows update on at this point, and just keep rebooting!
Well, my new PC is fine now. And I have updates off for the moment. I just don't want interruptions. What a cryptic set of messages I get when Windows is booting/repairing. Perhaps I should look at a log file somewhere and start to understand the install process more?
