Hello Kerry,
F8 for Windows 10 has been deprecated (though there are instructions on the net - it is easier to get to w/ new instructions). To get to the new boot menu hold this shift button when clicking on the power icon and 'restart'. Keep the shift key held down and before long you'll see a spankin new menu for you. You can do this at the log in or post log in.
As far as the issue - I get the exact same thing. Person who replied punted and said it was a graphics driver issue. Here is my reply in response - I hope this helps:
Hello,
Gowrisha,
My current driver for Nvidia is up to date: version 388.00 at this writing which is as up to date as you can get for a 960. Graphic driver updates are no longer the dominant issue for Windows since the decision to include them within their update scheme. Your tech article's example is slightly different from mine (see attached). As I wrote earlier, this is, per the green screen, likely because of volsnap.sys. I believe this file has more to do with software/hardware connection with the USB or storage. I also have no other pending updates except for build 17025.
The temporary fix for now for insiders if seeing this issue and their graphic driver is up to date as mine is:
1) As SOON as you get your regular windows wallpaper back up post boot try to hit Windows + X
(You are working on the clock here and need to get this done before the next update and the inevitable crash happens - so do this quickly!)
2) Select Windows PowerShell Admin
3) You'll unnervingly have to wait for an 'okay' for the shell to run. As soon as it comes up let the OS know that PowerShell Admin is indeed, 'okay.'
4) Run this command ASAP from the PowerShell Admin:
net stop wuauserv
This should stop the errant update service.
5) Quickly go to Settings / Update and Security. If it was in between initializing and downloading you may have to repeat step 4 because it'll just rerun wuauserv. If you have a button that says Retry, DON'T press it - the OS has temporarily given up on installing updates (this is a good thing for us). Feel free to use your machine for an unlimited time until you have to reboot and restart this entire process again.
These steps aren't the best, but at least you can use your computer for longer than 10 minutes at a time. Obviously it is a good idea to every once in a while try the update so you get the best working OS and security, but an OS isn't considered working properly if it is resetting within 10 minutes.
Hopefully Microsoft will be taking this situation seriously and working with insiders such as myself and others as to the cause to prevent this issue from reaching the common update ring.
Thank you,
Rob Milliken

When I tried this, it just keeps saying access denied - any clues?
This has kept crashing on me since Thursday when it updated automatically and I can't use my laptop which is causing major issues for me

Ian,
You think you have OWNERSHIP of your own files? HA. Seriously, MS does this so someone doesn't touch files they shouldn't and lock themselves out of the machine. Therefore the instructions I am about to give should contain some caution and come with no warranty. Definitely BACK UP your volsnap.sys to something else before replacing it. Read here how to take ownership of this file: http://www.winhelponline.com/blog/take-ownership-of-file-or-folder/ ... I find this is best done from the command line with administration privs. I did it without any special boot up into Window, just log in and get it done before your machine resets. I personally did this then copied an old volsnap.sys file (from same machine but a September volsnap in a windows.old directory) with Windows Explorer. Then I manually requested the update. I did honestly felt about as nervous as a person who is facing a firing squad because I tried this before with a different volsnap.sys from a laptop and it didn't work. Low and behold, about an hour later after starting the update, I was indeed updated and no more resets. I hope this works for you and ends up saving you time instead of wasting it. If you have an encrypted disk you may have to do more digging to get this to work (see original solution under Michelle's post on announcement of the 17025 release for more details).
Thank you,

Thanks for the feedback and suggestions Rob, but as I've just mentioned elsewhere, I'm operating from my iPhone and iPhone until I get another update from Insider Programme to fix the laptop. It seems that the Laptop is running really slow, so by the time it settles down to actually use, it goes Green Screen again! So, unless the next update fixes it, I guess the laptop is dead!!

Ian,
My feeling is that the update process in your current build is broken, therefore, the next update probably won't fix your issue since you can't update to it. This holds true at least to the situation I was in.
So, taking this a step at a time. When you first turn on your laptop are you getting to the log in screen? It is usually where the time of day shows up and you can enter a password. Also the power options, restart/sleep/hibernate are available here. You shouldn't get a green screen if you stop here (don't enter a password yet). If you do have an issue before you enter a password, there may be another issue at work. Anyway, can you get to this screen?
Thank you,
Rob Milliken

I just fixed this issue by copying the volsnap.sys from a different Insider Preview system to the affected system. The date stamp on the good file is (10/21/2017).
Since the laptop would not boot past the endless GSOD/BSOD, I first mirrored the HDD to another system and tried to copy the file over. The file is owned by the trusted installer and will not allow the copy, gets the Access Denied like you mentioned. I created a Generic Boot Key using WinPE and booted stand-alone. There are several boot utilities (but be careful of the ones you choose). So basically, boot the affected system from a boot key/thumb drive that allows access to the files and the copy should work.
Other factors you might have to get past are drive encryption, etc. Once past that, my system works now. Ready for the next update......
- Ian CalvertOct 31, 2017Copper ContributorThanks Jim but I'm stuck on using my iPhone and iPad until I can somehow get this fixed! Trying to do what you suggest - thanks btw - is not something I'm able to achieve, I guess I have to wait for another update I guess....
