Primarily, I was running Windows 10 on my PC, so I installed Windows 7 Ultimate which lead me to have many drivers missing from my PC. After that, I installed the drivers I needed to get important updates which made the PC work correctly. Then I upgraded to Windows 10 for free. I am now using Windows 10 with all updates and there are drivers which I had installed for Windows 7 in a folder called 'dell' in Local Disk C: Is it safe to uninstall these drivers?
