I carefully rolled back and turned off auto-updates. It solved the problem for 48hrs, but the update still slipped through at some-point. My story:
In December (before a 4 week trip abroad), I performed a full clean install to revert my Surface Pro 3 to a version before the bug appeared. I a technical person with easy access to all my installers, so it only took me about 2 hours to create the USB
image, and 5 hours to install and restore all my software.
The functionality with the power button and slider was restored upon the clean install. And, I thought that I shut off automatic updates to avoid having windows re-apply the Roll-up Patch which would break the features.
However, the patch (somehow) got pushed within 48 hours (about a day before my trip). And, all the problems re-Surfaced (Pun intended).
I was a help-desk and PC technician for years, so I'm usually pretty good at this stuff. I usually read at least 3-4 articles about how to perform something (like stopping automatic updates), to ensure that I see the same instructions twice and ensure I have
coverage of all the approaches.
Egotism aside, windows is designed to protect and update itself. I consider myself a desktop Vetran/Master on the scale of (Beginner, Novice, Intermediate, Advanced, Veteran, Master). I can make mistakes, but I couldn't even find where I'd error going
back in retrospective.
Based on this, I have the opinion that most average folks will not be able to successfully revert and permanently suppress updates to work-around the issues. I'm also not willing to invest another 4-6 hours to try another reset, because I can't find my
error (and the same problem will reoccur). I'm tempted to just upgrade, but I also lack the information to know which models this issue applies to (Surface Pro 3, 4, 5, book, etc).
As a result, I simply got a keyboard, added office, and installed a Bluetooth mouse (using mobility features) on my (renewed) iPad Pro 11". I prefer Windows, but the iPad has an 11hr battery life and can be recharged 4 times off a big Anker power-bank with
no access to an AC Outlet. It's not perfect, but I can perform 80%+ of the things I need to do. The only think I really miss from Win10 is tabbed browsing where I can also open tabs to windows, and floating windows.
I still really like my Surface Pro 3, and it's perfectly fine outside these issues. However, it's not aging well compared to devices powered by a USB-C that can be supplemented with an external charger. I think I'm just going to permanently dock it, and
connect it to a TV as a dedicated Home Theater PC (HTPC) unit... and treat it like a Win10 ROKU Ultra.
If I dock it, I'll periodically check every 3-6 months to see if Microsoft ever solves their bugs. If they do, I may bring it back into rotation as a traveling device. :-(
