1、一般来说，通俗用户向OEM购置预拆有Windows操做系统的计算机或向软件零售商购置零售版的Windows操做系统时，城市得到“实品证书(COA)标签”、“最末用户答应协议(EULA)”、“Windows系统安拆光盘”（有些OEM计算机附赠的是系统恢复光盘）、“用户利用手册”。
2、只要用户拥有合法的“实品证书(COA)标签”而且遵守“最末用户答应协议(EULA)”来安拆并利用的Windows操做系统，才算是合法的正版操做系统。若是用户购置了一份合法的Windows操做系统（含一个合法受权），但是安拆在两台或多台电脑上，无论是供用户本人或别人利用，都是不合法的，也便是安拆在其他计算机上的操做系统属于盗版系统。
3、Windows 7家庭通俗版399元，高级家庭版699元，专业版1399元，旗舰版2460元。相差如斯悬殊，原因就是正版带有序号。有些网站开设了专买序号营业，一般 是30-50元，也能使，但不保险，更好不买，否则会受骗。
必需有一个正版的密钥（从正规渠道购置的或者是品牌机自带的），能一般激活系统。
