Win7 system can be used directly ... after the first boot into the desktop ... the system will detect the hardware of the new computer and drive all related programs ... so it will take more time to turn on the computer for the first time ... Try not to use the computer at this time ... It is better to restart the computer before using it (because the driver has been installed). ..

Note: If the motherboard is not too biased, there should be no need to supplement the driver. ..

The installation package of win 10 is smaller than that of win7 ... That is to say, the system has been simplified ... If you want to bring a system hard disk ... and find another computer to use it ... it may not work ... or it may not work properly ... You need to make up some drivers! !
