(See “ The best places to find Windows 10 ISOs ” for info on obtaining the correct Windows 10 version/build from, UUP Dump, or the Media Creation tool, and use the Windows Insider Preview Downloads page for Windows 11 builds.) I recommend building an installable and bootable USB flash drive for this purpose you may need it again sometime. Bittedness must also be identical: 32-bit media for a 32-bit install, 64-bit media for a 64-bit install. To accomplish this, you’ll need installation media for the same edition (Home, Pro, Enterprise, or Education), language (en-US for American English, for example), and build as the currently installed edition. It means running the Windows 10 installer for the same version/build that is currently running on the machine from inside Windows 10 itself. This technique essentially involves overwriting the current OS installation with a fresh new copy while leaving your data files, settings, and preferences alone. If you have slow or inconsistent Internet, you should go to some place that has a strong connection and follow the instructions for creating a USB install disk you can use at home.Of 2 Step 3: In-place upgrade to current Windows 10 version

Though you can walk away for large portions of the process, you can expect all the downloading and file copying to take at least 60 minutes and, in our case, closer to two hours on a fast Internet connection.

Windows 10 should install without a hitch, but driver problems are a possibility and, during any system update, there's always a chance something will go wrong.
