WINDOWS SECURITY AND DRIVER UPDATES
Out-of-date drivers and operating systems can cause a variety of issues and are one of the first things to check when a game or program is having problems.
Even new computers can have out-of-date drivers and operating systems because updates are released routinely.
Some games and programs might run fine on a system with old drivers, but outdated drivers can still create technical issues with specific games or programs.
