更新完各个部件的驱动之后系统变得很卡（win 10系统）

[街头球狂]

只是系统安装程序，你得至少有win8之类的Key。

win7的key能用在10上面吗？我的10是从7升上去的

可以免费下win10?

installation media免费下载的。Windows 10 在你的计算机已经激活过，重装时很可能不需要key并自动激活。

How you activate Windows 10 after reinstalling it depends on how Windows 10 was originally installed on your device.

If you activated a free upgrade to Windows 10 or bought and activated Windows 10 from the Microsoft Store, you have a digital license for your device. This means you can reinstall the same edition of Windows 10 that your device has a digital license for without entering a product key. During reinstallation, if you’re asked to enter a product key, you can skip this step. Windows 10 will automatically activate online after the installation is complete.

干净安装是需要key的。

也不需要。跳过输入key，然后自动激活。微软那边有你计算机的硬件指纹的。

荡过win10然后装在一vm上，没提key的事儿。好久没run那个vm了，今天试一下看看win10是否还窝壳。
