I never understand why so many people find it so hard to change, and get used to a simpler way of doing things. Your computer has a power button, or (if it's a laptop) you can simply close it. Windows supports sleep and standby very well.
We have two oldfashioned desktop computers running Windows 10 in our home. They are shared by the family and kids for email, browsing and gaming, everyone (and even several of our kids friends') has a Microsoft account on each computer. The computers are turned "on" and "off" many times a day, using the POWER button. The computers take less than 3 seconds to start, as they are actually just sleeping.
