What should I do if the Win10 installation update causes a system failure?

After the release of Win10 preview, many users who love Windows will be willing to be Microsoft mice, but for the updates pushed by Microsoft, the system will crash without any reason after installation. The other way is to give him a body. Since it is an update, it is uninstalled.
Usually we can uninstall the update in the update management of the program, but Microsoft provides a better way:
We just hold down the shift key, then click the power button in the start menu and then restart, at boot time We will jump to the following interface:

At this time, we can choose the Troubleshoot option to enter, Troubleshoot Chinese means [fault detection], continue to press OK, the "Uninstall Update" page will appear. As shown below:

As long as we press the “uninstall” button, we can uninstall the update that is installed, and the fault that occurs after the uninstall can be solved. After Microsoft releases the revised update, it can be downloaded and installed.
When Microsoft's mouse, this sacrifice is worthy of praise, although you can experience the fun of new features, but the Win10 preview is in beta, don't use it for work.
