如果你的原因和我一样，这确实是一个烦人的修复: 我的名字包含一个扩展 ASCII 字符“ø”。当计算机在我的电脑上设置我的帐户时，就使用了那个。例如。 c:\users\Bjørn。

修复:将文件夹和您的家庭帐户重命名为 Bjorn。

在您的系统上创建另一个管理员帐户，您可以使用该帐户将帐户重命名为 c:\users\Bjorn\

以下是如何重命名帐户:https://superuser.com/questions/495290/how-to-rename-user-folder-in-windows-8

我一开始就不会在用户名中使用扩展字符，但是当我几年前安装 Win8 并且刚开始可以使用 Microsoft 帐户时，向导选择了用户名。
