Is working with the mouse and keyboard at times too sluggish for your liking? Well, Windows 10 is a touchscreen-optimized operating system (just like Windows 8 was), so with just a finger prod, it can do a lot of cool stuff rather quickly.
One of the most innovative features Microsoft has built into Windows 10 is Windows Hello. Basically, it allows a user to login virtually instantly just by using facial recognition (or a fingerprint).
Safe Mode is just what you would expect-a secure way to boot up a PC and run the system without startup apps and only essential drivers, which should hopefully allow the computer to boot effectively when it won't otherwise because of some problem or other.
If you notice that you are not able to successfully activate Windows 10, Microsoft has introduced a new activation troubleshooting feature in the Anniversary Update. In Settings, you will find this, then click Update & Security, go to Activation, and choose Troubleshoot (if the OS has been enabled, you won't see this option).
