Windows 10 October update now available

system restore via control center restored my files & rolled back the update

Grabbed the ISO on Tuesday 10/2 and have done 4 desktops with DVD in place upgrade and 1 laptop with a msdc in place over 1803 with no problems.  I keep my main data on separate hdd(s) and/or ssd(s); but also utilize the user/documents etc. structure for unimportant files.  Everything ported OK on all systems and I use OneDrive. I guess things are aligned for my systems this week as I usually get hit with these problems; hence the Important Data is always kept on Separate Drive(s) with redundant backups everywhere. Been using 2Brightsparks SynBackFree for Decades.

Exactly. People don't understand the value of backups until they login one day and their drive has crashed and or the OS blew up. I do system images twice a week to a separate drive and my 4TB data drive gets backed up to a WD external 4TB twice a month. That ext drive then gets taken out of the loop so if anything happens to the system where everything is hosed, I still have my ext 4tb drive with all my data intact. I trust manual tactics far more than any automated backup suite. Just my opinion

They sure don't. I save an image once a month, and I keep three months' worth.  And I save one whenever I'm going to be doing a major update/upgrade, such as this.  

I have three PCs, and I ran out of room on my 750GB USB external drive, so I now just save the images from my desktop and laptop on that drive, and for my notebook I save them on the HDD I removed from it when I replaced it with an SSD.  Surprisingly, it works with the USB adapter that came with the SSD .  It's 2.0, so it takes a while, but it works.  With my desktop, I also save its images on a separate internal HDD (in addition to the external USB drive).  A bit redundant with the desktop, but one can never be too careful.

after installing this download most of my saved files were deleted however i managed to system restore which looks like it has restored all deleted files & blocked updates in the administrator tools

I upgraded both my desktop and laptop, with the former being done through Windows Update and the latter through the Upgrade Assistant (I didn't want to wait).  Other than an issue of having no Windows startup or shutdown sound, and having an issue with notifications, I didn't have any issues to speak of.  No missing files or folders.  The notification issue was that the popup would occur on the bottom right, but when I would click on the notifications icon on the bottom right, nothing would be there.  

Still, due to the issues, I decided to go back.  Luckily, I'm one of the folks who saves a system image before any major updates or upgrades, so going back was relatively easy.  I don't trust the rollback feature.   So, I restored both with the system images and all is well.  

When it is released again I am going to download it using the Media Creation Tool, burn the ISO to a DVD, and upgrade both using that.  I'm on a capped ISP, so doing that will help me save data over upgrading each one through Windows Update.  And, of course, I'll be saving a system image from each before upgrading them.  Everyone should.  It can save you from a major headache.  

I'll be waiting...

I don't back up my pc at all, i don't even have a drive for a backup
