1、一般来说，普通用户向OEM购买预装有Windows操作系统的计算机或向软件零售商购买零售版的Windows操作系统时，都会得到“真品证书(COA)标签”、“最终用户许可协议(EULA)”、“Windows系统安装光盘”（有些OEM计算机附赠的是系统恢复光盘）、“用户使用手册”。
2、只有用户拥有合法的“真品证书(COA)标签”并且遵守“最终用户许可协议(EULA)”来安装并使用的Windows操作系统，才算是合法的正版操作系统。如果用户购买了一份合法的Windows操作系统（含一个合法授权），但是安装在两台或多台电脑上，无论是供用户本人或他人使用，都是不合法的，也即是安装在其他计算机上的操作系统属于盗版系统。
3、Windows 7家庭普通版399元，高级家庭版699元，专业版1399元，旗舰版2460元。相差如此悬殊，原因就是正版带有序号。有些网站开设了专买序号业务，一般 是30-50元，也能使，但不保险，最好不买，不然会上当。
