Updating microsoft computer crashed
You can opt into the Windows 10 Insider program at any time, but you may experience problems with the new builds, especially if you're in the Fast ring. Windows 10 does its best to keep your system automatically updated, but it may not always be perfectly up to date (for example, if you've been using a metered Internet connection).
For the most part, updates are a good thing -- they fix software incompatibilities and help your computer run smoothly and efficiently.
For what fixed the problem that I was having, see my post that starts with me saying I fixed it.
I had Windows 7 automatically downloading and installing critical updates. On 8/7/2012 a critical update was automatically downloaded and installed, unnoticed by me.
Windows 10 Insiders get Insider Preview builds of Windows 10 -- builds that are not quite (or even sort of) ready for the public, but that allow you to try out and give feedback on new features.To go back to an earlier build of Windows 10, open the Settings menu and go to Update & security.Click Recovery and, under Go back to an earlier build, click Get started.Uninstalling a recent build will affect changes made to your computer since that build has been installed.This includes apps and programs you've installed, as well as any changes made to settings.
Yes, you should still install everything listed in Windows Update, but don't fear the same problems so long as you follow the advice in How to Prevent Windows Updates From Crashing Your PC.
