Details of reloading the system

Generally speaking, there are two situations to reinstall the system:

1, passive reloading: due to various reasons, such as user misoperation or virus or Trojan horse damage, important files in the system are damaged, leading to errors or even crashes, so it is natural to reload the system; Sometimes, although the system runs normally, there will still be errors from time to time. It is better to reinstall it than to take time and effort to find it.

2. Active reinstallation: Some DIY enthusiasts who like to fiddle with computers will reinstall the system regularly even if the system is running normally, so as to reduce the weight of the bloated system and make the system work in the best condition.
