You have a computer named Computer1 that runs Windows 10 Enterprise.
You plan to install the most recent updates to Computer1.
You need to ensure that you can revert to the current state of Computer1 in the event that the computer
becomes unresponsive after the update.
What should you include in your solution?

A.
The Reset this PC option from the Recovery section of the Settings app

B.
The Sync your settings options from the Accounts section of the Settings app

C.
The Backup and Restore (Windows 7) control panel item

D.
The Refresh your PC option from the PC Settings

Explanation:
The question states that you need to ensure that you can revert to the current state of Computer1. The question
does not specify what exactly the current state is in terms of software configuration but it would be safe to
assume that Computer1 has Windows Store Apps installed, desktop applications installed and some previous
Windows Updates installed.
The only way to recover the computer to its ‘current’ state is to perform a full backup of the computer before
updating it. Then if the computer becomes unresponsive after the update, we can simply restore the backup to
return the computer to its state at the time of the backup.
Incorrect Answers:
A: When you Reset your PC, all your applications and data will be removed. It is like doing a complete
Windows reinstall and formatting your hard drive.
B: The Sync your settings options are used for syncing settings with a Microsoft account. This does not return
the computer to its current state.
D: When you Refresh your PC, your data, Windows Store Apps and application settings will be preserved.
However, all your desktops applications and any existing Windows Updates will be removed. This does not
return the computer to its current state.
