After years of updates, Windows 10 has become increasingly stable and secure. Although Windows 11 has been officially released for several years, Windows 10 is still the OS with the highest market share. Although Windows 10 is highly stable, reinstalling may be necessary when virus damage makes the OS become unstable, or you need to replace the mechanical disk with a fast SSD. Computers shipped in recent years lack CD/DVD drives, so users usually have to create a Windows installation USB drive to install Windows 10.
