Start by finding a dongle you like: Google can help.

如果您要使用某些USB设备作为加密狗，则可以从中读取一些数据(例如，供应商ID和产品ID)使用WMI，加密"该信息(使用公钥/私钥对进行散列或真实加密)，并将其存储在软件中的某个位置.然后，您的软件可以检查是否存在USB设备，并做出相应的反应.
尽管无法简单地复制该USB记忆棒，但是同一型号的另一个标本会假装"为正确的标本-您可以尝试通过使用品牌设备隐藏该信息.

In case you want to use some USB device as your dongle, you can read some data from it (e.g. vendor id and product id) using WMI, "encrypt" that information (hashed, or real encryption using a public-private pair of keys) and store it somewhere in your software. Then your software can check if that USB device is present, and react accordingly.
Though that USB stick cannot be simply copied, another specimen of the same model will "pretend" to be the correct one - you could try to hide that information by bying branded devices.

您可以安装Windows XP USB版本，可以在这种情况下提供更多控制，是最佳选择

You can install Windows XP USB edition, which gives more control in this type of scenario and is best option
