How to Prepare for a Clean Install of Windows 10

I. What to know in advance:


1- There is no 'one best way' to do a clean install. There are as many different approaches as there are different personalities.


The internet is filled with detailed instructions for performing a clean install. When doing your research on the internet, read many different approaches and then craft one that fits your style. Look particularly for tips from peoples' real life experiences.


Some of the best advice you can get will come from people who have already installed Windows 10 on your very own model of computer. You can find them in the computer manufacturer's own community forum, or on public forums like Reddit.


2- Make sure that your hardware and software are supported on Windows 10.


'Supported' means that the hardware manufacturer or software developer has tested the hardware or software on Windows 10 to see that it will work correctly; this includes updating the device driver to keep up with all the changes to Windows 10 over time.


You can install Windows 10 on unsupported hardware or with unsupported software, but in that case it's your responsibility to find out if the hardware or software will work properly on Windows 10. With supported hardware and software, the responsibility falls on the hardware manufacturer and the software developer.


There's no point to doing a clean install if you're not certain that Windows 10 will work correctly on your computer's hardware.


3- Prepare, prepare, prepare.


By the time you're ready to start your clean install, you should know exactly what to expect. That includes knowing what the screens will look like, what questions you'll be asked, and what your answers will be. Your goal should be 'no surprises.' You want to get this right the first time.


It's worthwhile to invest time in preparing for your clean install. Don't worry - you're only going to be doing this one time. (What? I'll explain why at the end.)


4- A clean install erases your C: drive - anything you haven't backed up will be gone.


The installer doesn't physically erase your hard drive - it erases the metadata that knows how to find your files, so they are, for all intents and purposes, gone. Think of everything you wouldn't want to lose and make sure it's backed up.


II. What to prepare in advance:


1- A Windows 10 installer on a bootable USB flash drive or a DVD


It doesn't matter what version of Windows 10 is on the installer; you'll be updated to the most recent version as soon as you connect to the internet. A more recent version means your computer will need less time to be completely up to date.


2- A list of all the applications (formerly known as 'programs') that are installed on your computer


In addition to the obvious (name and developer) you should include in your list whatever information is needed to register the software. Usually, that's your name and/or email address, and the license key that you received if you bought the software, and any special steps that you may need to follow.


It's also a good idea to have a copy of the actual installers on a USB flash drive, or the original installation disks. That way you won't have to go looking for them when the time comes to install, and you'll be able to install even if you're having trouble with your internet connection (so you can't navigate to the developers website to download the installer.)


3- A list of all the device drivers that you need to install


Make sure to install drivers for Windows 10. Sometimes a hardware manufacturer hasn't written a driver for Windows 10 because the Windows 8 (or Windows 7) driver will work just as well on Windows 10. If you hear that from the hardware manufacturer, you can count on it.


As above, it's a great idea to assemble the actual installers in advance, along with any instructions you may want to have in order to install the drivers.


Only obtain drivers from the hardware manufacturer's own website.


4- A checklist of what tasks to perform after your clean install.


For example: how will you setup your user accounts? what configuration settings do you want to make? how will you setup your home network? what tests do you want to perform to make sure everything is working properly?


Thinking about these things in advance means that your computer will be setup and ready to go in the least possible amount of time, and you'll know that everything has been setup exactly as you like.


III. One bit of advice to consider: Complete your clean install before you connect to the internet.


You can perform a complete clean install without being connected to the internet. That includes your post-install checklist. There are two advantages: 1) you won't be interrupted during your work to install updates; and 2) you won't have to worry about possibly being hacked during the install.


Once you are completely done, then connect to the internet. Windows 10 will then activate and hours of updates will arrive at your computer.


IV. Post-install


Now you have a completely pristine and up-to-date computer, setup exactly as you like. After a celebratory thimble of single malt, the very next thing you should do is to make an image backup of your hard drive.

You've invested many hours to get this far, possibly many days. You don't want to have to go through this ever again - and you don't have to. Make an image backup of the way your computer is now. In future you can restore the image, which takes only minutes, and your computer will revert to exactly the way it is now. You will never have to re-install Windows or your software again.
