Luckily, the Get Windows 10 app also includes a PC checkup tool that will list any problems with your computer, and various other information you need to know before the upgrade. You also have to make sure your apps, all your hardware, peripherals, and drivers are compatible as well. If you were able to make a reservation, it means that your computer or tablet is compatible with Windows 10, but it doesn't mean you won't encounter any issues at the time of the upgrade. Making a reservation before it releases will ensure your PC will get the new operating system as soon as possible. So, this means that as we have previously reported, Windows 10 won't be available for everyone at once on July 29. Later on, everyone else will get the upgrade as well. The company will continue rolling out Windows 10 gradually to everyone else who reserved the copy using the 'Get Windows 10' app and those who bought a new PC.

On July 29, Microsoft will begin rolling out its new operating system starting with machines that are part of the Windows Insider Program.
