好消息是：如果你有一段时间没有更新你的Realtek蓝牙驱动程序，或者你甚至不知道这是一件事，你最终可以更新到Windows10版本1909最新和最伟大的迭代操作系统时，我们发表了这篇文章。

据Bleeping Computer称，由于旧版本的Realtek驱动程序导致新版本操作系统上的设备连接出现问题，Microsoft已删除一个阻止您升级到此版本，甚至Windows 10版本1903和1809的块。

不管这个问题是什么，它已经被更新版本的Realtek驱动程序修复了。从理论上讲，您应该能够通过Windows update本身1.5.1012或更高版本（也就是说）更新到这些文件的最新版本。打开“设备管理器”，展开“蓝牙”部分，右键单击并选择“属性”，然后单击“驱动程序”选项卡，可以查看正在运行的内容：

如果您运行的是较旧的驱动程序，并且Windows update没有更新可用，则可以尝试手动安装Realtek的蓝牙驱动程序。这看起来是一个非常复杂的过程，但你会没事的。正如Microsoft所描述的：

1. Download both of the Realtek Bluetooth radio drivers to your preferred folder: Driver 1, Driver 2. Note We recommend downloading them to your Documents folder.
2. Open File Explorer. If there is no file explorer icon in the task bar, select the search box and enter file explorer and select it.
3. Within File Explorer, go the the Documents folder or the folder you downloaded the drivers to.
4. Find and double click or double tap on the file named 068de0d6-6ac2-473a-8cbd-bd449cd5c97c_942eec5828662eecc6b98cc2706658bf2433717c.cab

21. It should now find the updated drivers and install them. Wait for this to complete and select Close.

一旦你做到了这一点，在等待windows10更新到最新版本的同时，你可以尽情地想一杯清爽的饮料。然而，我不会开始倒它，直到你有确认更新准备好下载和安装；微软表示，在你更新了蓝牙驱动程序后，可能需要48个小时左右的时间才能使用Windows更新。
