HOW TO DO A CLEAN INSTALL OF WINDOWS 10
1- The first step would be to buy Windows 10 Pro 64 bit software. Plan this for a weekend to you are not rushed.
2- Then backup all data, make sure you don’t forget your Favorites, My Documents and anything that is on the desktop.
3- If you have proprietary programs like trading, Quicken or Quickbooks or professional software. Contact your software vendor about that data as it may be stored in a different location.
4- Gather all of your program software. This includes proprietary software, Microsoft Office etc. If some of your programs have been downloaded find them and put on a USB stick to have ready. If you need to download them again, do this now before you start the new Windows 10 install.
5- Once you are double sure you have backed up all of your data, you have all of your program software and ready to start,turn off your computer.
6- Pull out the Windows 10 CD, boot the machine and right away pop the CD in the drive. The system will boot from the Windows 10 CD and start to install. If you miss it and it boots to previous operating system, just reboot again. When you see the Windows 10 logo and the lights flashing on the front of the DVD you know it is loading.
7- Follow the procedure to install Windows 10 completely. Note during the install it prompts you to create a Microsoft account. You do NOT have to do this, there is an option to create OFFLINE account (like you have now) choose that option. Once it is finished your system will reboot leaving you at the desktop. Your clean install is complete.
8- Reinstall all of your programs, then copy all of your data back to the system.
9- Windows 10 is pretty good about automatically finding drivers, but double check the Device Manager to see if any are missing. Test your printers and other peripherals to make sure everything is working and you are DONE.
