Windows 8.1 Pro是Windows操作系统的一个版本，微软于2013年作为Windows 8的更新发布。与前代产品相比，它包括多项新功能和改进，包括重新设计的 “开始” 屏幕、增强的搜索功能以及对多任务的更好支持
。Windows 8.1 Pro适用于商用计算机，包括诸如BitLocker加密、远程桌面和域名加入等功能，这些功能在Windows 8.1的标准版本中不可用。一些用户发现Windows 8中引入的界面更改具有挑战性，而Windows 8.1 Pro旨在通过重新引入 “开始” 按钮并允许用户直接启动到桌面来解决其中的一些问题
。但是，自2023年1月起，微软不再支持Windows 8.1 Pro，鼓励用户升级到Windows的最新版本，例如Windows 10，以获得持续的安全更新和支持。使用不受支持的操作系统可能会使你的计算机容易受到安全威胁，因为 Microsoft 将不再发布更新或补丁来修复任何新发现的漏洞
。如果你仍在使用Windows 8.1专业版并希望升级，则可以考虑购买更新版本的Windows，例如Windows 10或Windows 11，具体取决于计算机的硬件要求。
或者，您也可以考虑切换到其他操作系统，例如 macOS 或 Linux 发行版。在升级操作系统之前，请务必备份数据并确保您的计算机满足新操作系统的最低硬件要求。
升级后，您可能还需要重新安装一些应用程序和驱动程序。
在哪里购买Windows 8.1 Pro？

Windows 8.1 Pro 适合玩游戏吗？
如果你不需要 DirectX 12，或者你想玩的游戏不需要 DirectX 12，那么在微软停止支持Windows 8系统之前，你没有理由不能在Windows 8系统上玩游戏。

- 硬盘：16GB 可用磁盘空间（32 位）/20 GB（64 位）
- 显示器：屏幕分辨率至少为 1024x768 像素。
-
1。选择 “开始” 按钮，键入 “电脑设置”，然后从结果列表中选择 “电脑设置”。
-
2. 选择 “激活 Windows”。
-
3. 在 “激活 Windows” 屏幕上，单击 “输入密钥”。
-
