My Windows 10 installation was recently crippled, when it automatically installed updates more than one at a time. Similarly, other users experience the symptom of a frozen taskbar after doing the upgrade to Windows 10 rather than the clean install. At any rate, I believe it is a corruption of system files and/or driver conflict which lead to this issue, the best documentation on it I could find is here.
My system’s functionality was reduced to a minimum after I installed Microsoft Office and logged out. The safe boot allowed me to get more functionality and revert to a system restore point (glad I made one last week) which resolved the issue and did not result in a loss of any data. Even my Firefox session tabs were maintained after reverting to the restore point.
“Well, should I upgrade to Windows 10 or not?” Go for it.
Other than that, Windows 10 has been fairly stable for me, despite being so early in its release. Though being a pain in the ass to switch off all the default privacy invading settings, the operating system has been stable and bug free. They brought the start menu back (sort of), but with news feeds and app store clutter being dragged into it. I would recommend making the upgrade to Windows 10 now if Microsoft will be charging money for the upgrade in the future.
Other reasons for upgrading to Windows 10: DirectX 12, an Xbox app, and Cortana (if you’re into that kind of thing). In my opinion, the biggest thing is the (forthcoming) DirectX 12 – a big step forward in the API allowing for gamers and developers alike to squeeze more performance out of a GPU. Here is an Ars article with more detail. A common metaphor I see used to describe the improvement from the previous version is to liken the processing pipeline to a waiting line of customers at a fast food restaurant: instead of waiting at the end of a long, zig-zagging line to get one order of small fries, a new register is opened up, specifically for parties of one. Or patrons ordering only fries. Polite, everyday customers in reality are mutually aware of engineering principles like this – they’ll let you go ahead of them in line to be more efficient!
“What about all that privacy invasion stuff I hear about?” It’s probably not as bad as you think. Yet.
Again, the main thing is that the privacy settings default to allow use of personal user data. You have to manually go through the settings menu and click “No I don’t want to give you access to my camera. No I don’t want to give you access to my calendar. No I don’t want Cortana to study my language productions.” Here’s what the menus look like:
And as you download apps (or as they’re added with updates. I don’t remember having Windows Maps…) you will have to uncheck or turn off permissions for that specific app. I still don’t know why I have “apps” on my PC, but whatever.
