Windows产品密钥查找器和Erij J.及其他人提到的其他解决方案仅适用于Windows XP和Windows 7.自Windows 8以来,Microsoft已经更改了密钥加密算法.
我在这里找到了适用于Windows 8及其博客的解决方案:http://winaero.com/blog/how-to-view-your-product-key-in-windows-10-windows-8-and-windows -7 /
但它是用VBS编写的,所以我把它重写为C#.

以下是如何在Windows 8及更高版本中解码产品密钥的代码:
public static string DecodeProductKeyWin8AndUp(byte[] digitalProductId)
{
var key = String.Empty;
const int keyOffset = 52;
var isWin8 = (byte)((digitalProductId[66] / 6) & 1);
digitalProductId[66] = (byte)((digitalProductId[66] & 0xf7) | (isWin8 & 2) * 4);
// Possible alpha-numeric characters in product key.
const string digits = "BCDFGHJKMPQRTVWXY2346789";
int last = 0;
for (var i = 24; i >= 0; i--)
{
var current = 0;
for (var j = 14; j >= 0; j--)
{
current = current*256;
current = digitalProductId[j + keyOffset] + current;
digitalProductId[j + keyOffset] = (byte)(current/24);
current = current%24;
last = current;
}
key = digits[current] + key;
}
var keypart1 = key.Substring(1, last);
const string insert = "N";
key = key.Substring(1).Replace(keypart1, keypart1 + insert);
if (last == 0)
key = insert + key;
for (var i = 5; i < key.Length; i += 6)
{
key = key.Insert(i, "-");
}
return key;
}

要检查Windows版本并获取digitalProductId,请使用以下包装器方法:
public static string GetWindowsProductKey()
{
var key = RegistryKey.OpenBaseKey(RegistryHive.LocalMachine,
RegistryView.Default);
const string keyPath = @"Software\Microsoft\Windows NT\CurrentVersion";
var digitalProductId = (byte[])key.OpenSubKey(keyPath).GetValue("DigitalProductId");
var isWin8OrUp =
(Environment.OSVersion.Version.Major == 6 && System.Environment.OSVersion.Version.Minor >= 2)
||
(Environment.OSVersion.Version.Major > 6);
var productKey = isWin8OrUp ? DecodeProductKeyWin8AndUp(digitalProductId) : DecodeProductKey(digitalProductId);
return productKey;
}

我在几台机器上测试了它,它给了我正确的结果.即使在Windows 10上,我也能够获得通用的Windows 10代码(在升级后的系统上).
注意:对我来说,原始的vbs脚本返回错误的Win7键,尽管原始的博客文章声明代码适用于Win7及以上.因此,我总是回归到Win7及更低版本的众所周知的旧方法.
希望能帮助到你.
