There was a major Windows 10 update that got pushed out this week. While Microsoft does not use language like "SP1" anymore (service pack 1), this was the equivalent of their first mega update for Windows 10. The formal name of this update is Cumulative Update for Windows 10 for x64-based Systems (KB3105213). You need it. If you are the kind of person that does not keep your computer on for long period of time every day, please keep it on for a while after reading this message. When you finally go to Shut Down, you will notice a message to the effect of "installing updates". You may have gotten this message already since Tuesday. By early next week, if you are unsure if you have the update you can always go to "Settings" on your start menu or by typing setting in the Search box at the bottom. Then go to Update and Security >> Windows Update.

You will see when Updates were last checked and you can also Check Now or Install Now, depending on what state your computer is in. Clicking Check Now or Install Now are both fine choices, if you have gone through the effort of getting to this point. In the general sense, Windows should be performing your updates automatically. I am just giving you the instructions here to check for yourselves.
There were also routine security and stability updates for Windows 7 and 8.1 this week if you have not upgraded to 10.

I should offer one final note about this week’s Windows 10 update. This update and the improvements it brings to Windows 10, captures the essence of what Microsoft intended with Windows 10. None of my clients have had significant or performance altering complaints with Windows 10, even when I upgraded many clients to Windows 10 in the summer. This week’s update merely puts the decorative glaze on the fact that Windows 10 was already cemented as Microsoft’s most successful operating system launch ever. If for some reason you are still on Windows 7 or 8, it’s going to be harder to stay on those platforms. While Microsoft is not going to slip 10 on there by surprise, it will be harder to avoid the upgrade by early next year (through notifications and changes to the Windows update process). I am telling you now, so there is no surprise. However, if your computer is more than 5 years old you should buy a new one. I would avoid putting 10 on one of those systems. A business class — Windows desktop or laptop will be best for my clients. I am thinking about Lenovo, Dell, and HP systems here. These are not computers that can be purchased in big box stores.
