HOW TO REFORMAT YOUR PC
Read the whole thing before you start.
It looks like a lot more than it really is, it typically takes around 20 minutes, depending on your internet connection.

Warnings:
-Back anything you want to keep up, on external drives. Do not try to put them on an internal drive, or skip the step about deleting the volumes later on, otherwise you can't guarantee that you have actually removed all traces from your drives.
-We are not responsible for any damage you do to your PC while working in windows or in BIOS. Though you really only need basic reading skills to execute this process properly.

What you need:
- A usb Drive 8GB +

Setup (In windows, before reformatting):
Plug in your USB
Download the windows install media creation tool: https://www.microsoft.com/en-us/software-download/windows10
Run the tool as admin to avoid any issues with windows being a bitch.
Accept the terms, and let it load. It may take a minute.
Select the "Create installation media" option, not 'upgrade this PC now'
Make sure the edition is 'Windows 10'.
Select the "USB Flash Drive" option. NOT 'ISO file'
Choose your flash drive and follow the directions. It will download the installer and prepare the drive to be bootable.

Booting into the windows installer:
Reboot your PC into BIOS or into boot select. To do this, reboot your PC and press whatever button is the setup button for your main board. This varies between manufacturers and models, but the DELETE key, F12, or F8 key are pretty common. Look up BIOS instructions for your specific motherboard.

Once you're in BIOS, navigate to the Boot options and find boot order or boot select. Make the USB drive with the windows installer the first priority, or move it to the top of the list (depending on style).

Save your changes and reset the PC.

Now when you reboot, your PC should boot into the windows setup menu.

Installing windows:
There are a few key points during the windows install you need to pay attention to.

1. When asked if you want to do a 'custom install' selected custom install. This allows you to delete volumes from your drives.

2. The 'select a drive' screen, this is very important.
You should have a display of all your drives with their volumes shown in the window. Click each one and delete it. You should do this until all you have left is 'Unallocated space'.

Once you have only unallocated space, select the drive(s) you wish to use and click create new volume.

Select the volume you wish to install windows to (whatever drive you're using, select the largest partition on that drive, not the 'system reserved' partition).

Install to that drive.

3. When asked to provide a windows key, just select "I don't have a key"

4. When asked to sign in to a Microsoft account, select 'Use offline account'.

Once your PC reboots for the first time during/after the main install, remove the USB drive. (Some motherboards may require you to enter the BIOS and change the boot order back as well, many do this automatically now).

Setting up windows (post-install)
The windows install setup may take some time, but there are a few things you should do before you try to setup our products on your machine.

First, update windows. Use the windows updater to get the most current windows updates. This may require a restart for some updates.

Next, update the primary drivers, this is your chipset driver, Graphics driver, etc. Go to the support website for your motherboard to find the best drivers for your setup.

Now's also a good time to get rid of anything you do not want on your PC, microsoft likes to install all kinds of apps and stuff with their updater now, so go into the 'Add and remove apps' tool in windows, and uninstall the stuff you aren't going to be using. (like games, the facebook app, etc.) Note: not every app on this list is un-installable from this tool

You can also take this time to adjust other settings, like disabling the windows defender system (you can use the Sordum defender control tool if you want it completely off), disabling UAC, disabling Fast Boot, etc.

Congrats, you reformatted your PC.
