Windows 10 Clean Install, what does it delete?
I currently have a custom built desktop that is running Windows 8.1 Pro (activated). I have three hard drives, an SSD for Windows and programs, a 1TB hard drive for games, documents and other files and a 3TB hard drive for backups. I have backed up the more important files on the 3TB and do not want to wipe it.
I would like to upgrade to Windows 10 and start again, wipe everything that is on my SSD and on my 1TB hard drive since it is full of stuff that I don't need and would take way to long to manually sort it out. Since I don't want to wait for the Windows 10 update to come through automatically, I created a Windows 10 USB. Running the setup.exe file on the USB gives the option of doing a clean install. I was wondering what this actually deletes. Does it wipe just the drive it is being installed on or does it wipe all drives on the system?. Sorry if this question has been asked before, couldn't find anything specific for what I am wanting to do
