問題描述

在Java中，我們可以通過查看os.name的屬性值來知道底層操作系統(tǒng)的名稱:System.getProperty("os.name").

In Java, we can see the property value of os.name to know the name of the underlying operating system: System.getProperty("os.name").

對(duì)于每個(gè)版本的 Windows，它總是返回操作系統(tǒng)的確切名稱:Windows XP 表示 XP，Windows Vista 表示 Vista，Windows 7 代表 7，Windows 8.1 代表 8.1，依此類推...

For each edition of Windows, it used to return always the exact name of the OS: Windows XP for XP, Windows Vista for Vista, Windows 7 for Seven, Windows 8.1 for 8.1, and so on...

問題是:我剛剛使用發(fā)布的 Microsoft 更新程序?qū)⑽业?Windows 8.1 更新到了 Windows 10，而且這個(gè)屬性似乎仍然存在 Windows 8.1:

The problem is: I just updated my Windows 8.1 to Windows 10 using the released Microsoft updater, and it seems like this property still remains Windows 8.1:

public class OSTest {
  public static void main(String[] args) {
    System.out.println(System.getProperty("os.name"));
  }
}

如何為此創(chuàng)建解決方法?而且，有誰知道如果安裝新的 Windows 10 副本，這個(gè)問題是否仍然存在 - 也就是說，這個(gè)錯(cuò)誤是由 Microsoft 自動(dòng)更新程序引起的 - ?

How can I create a workaround for this? And, does anyone know if this problem persists if installing a fresh Windows 10 copy - that is, this bug is caused by the Microsoft auto-updater -?

推薦答案

這是一個(gè)已知問題 JDK-8066504 已在即將發(fā)布的 Java 8 更新 60 中修復(fù).

This is a known problem JDK-8066504 that has been fixed in upcoming Java 8 update 60.

原因是 GetVersionEx 函數(shù)的行為自Windows 8.1.

The reason is GetVersionEx function has changed its behavior since Windows 8.1.

有多種可能的解決方法，請(qǐng)參閱 MSDN 文章.

There are multiple possible workarounds, see MSDN article.

最簡單的就是執(zhí)行cmd.exe/c ver.

另一種是查看其中一個(gè)系統(tǒng)文件的版本信息，例如kernel32.dll.

The other is to look at the version information of one of the system files, e.g. kernel32.dll.
