Adobe Photoshop CC 2018 abruptly stops working. Requires upgrade to Windows 10 to run.

Then which version of photoshop can I use in Windows 10 version 1511

I like the last statement, "in the future check the requirements before updating"
NO ADOBE, Why don't you check the Operating System capabilities before Self Updating or Forcing an Update.
Seriously, I get the Update Photoshop notice several times a day, I was one who had to roll back a couple of version because, like many, I am on a corporate environment machine and out IT department will NOT be rolling out the anniversary updates to any of our computers.

I want this fixed, I want the new features without having to update something I cannot update. 

All good to move this to the Photoshop section, I am finding that even changing back to older versions of Photoshop I can no longer use it on my pc!! I an unable to update the windows 10 version as other software I rely on does not work well with it.

This needs to be fixed, as why do we pay a subscription service that will stop us from using what we pay for. I did not see anything suggesting that it requires the updated win 10.

Adobe, I am an artist and I rely on my software working, every day down is a lost day. Please take this serious.

Moving this discussion to the Photoshop forum.

Likewise, I am too on an Enterprise version of Windows 10 and stuck with the Out of Date versions.
Thanks Adobe...

Perhaps you should create a version that maybe disables the useless features that come from the Creators update in Windoze.

This needs to be fixed.  Rolling back lost settings.  Lightroom won't launch PS.  PS prompts to update system every time.  Don't have the new features like the smart select.   Are we stuck on old PS forever or just upgrade every once in a while and hope and rollback?

I had this issue too. I'm also working on Windows 10 Enterprise. It would be great if Adobe CC updates would check the system for requirements. It would save a lot of time spent troubleshooting.

For people who need to know how to fix this right now, I'll answer this here.

How to Fix this, and get Photoshop back working:

1. In your CC window interface, on the photohop dropdown, go to "Other Versions" A list of previous Photoshop versions will pop up.

2. Click "Install" from the top version in this list. This should roll you back to the version that you just left when you updated.
