激活您的计算机（属于您的组织的一部分）时，您会收到错误0xC004C020，其中显示 - 激活服务器报告多次激活密钥已超出其限制 -^{(The activation server reported that the Multiple Activation Key has exceeded its limit—)}您可能需要一个新密钥。这篇文章将指导您为什么会收到错误代码以及如何解决它。

0xC004C020， 激活服务器^{(Activation Server)}报告多次激活密钥^{(Multiple Activation Key)}已超过其限制

虽然零售密钥只能使用一次，并且可以转移到新计算机，但它们不能用于激活多个Windows系统。相反，该组织使用所谓的MAK 或多次激活密钥来激活具有相同密钥的多台计算机。

使用MAK 密钥^{(MAK Keys)}的缺点是它们只能使用一次，并且它们被设置为激活特定数量的设备。该计数已预先配置为Microsoft和Enterprise之间的交易。每次^(Every)使用MAK激活设备时，总计数会减少 1。

可能是你的电脑被格式化了，你之前的密钥丢失了，或者当管理员给你激活的密钥时，它已经超过了激活次数的限制。

你应该打电话给你的系统^(System)管理员来解决这个问题。如果您是系统管理员并且认为没有超过限制，您可以致电Microsoft支持来解决此问题。

MAK密钥通常用于服务器设备或格式化或重置的可能性很低的计算机上。由于一次性激活功能以及因此对激活的限制，它们的成本也比其他产品低得多。

如果您收到一个您怀疑的密钥，并且需要弄清楚密钥的类型，那么您可以使用slmgr /dli命令。它将显示它是Retail、OEM、KMS还是MAK密钥。

希望您解决 0xC004C020激活^(Activation)错误。

Activation Server reported that Multiple Activation Key has exceeded limit

When activating your computer, which is part оf your organization, you receive an error 0xC004C020, which says—The activation server reported that the Multiple Activation Key has exceeded its limit—the chances are that you need a new key. This post will guide you on why you get the error code and what you can do to resolve it.

0xC004C020, Activation Server reported that the Multiple Activation Key has exceeded its limit

While Retail keys can only be used once, and they can be transferred to a new computer, they cannot be used to activate multiple Windows systems. Instead, the organization uses what is called MAK or Multiple Activation keys to activate multiple computers with the same key.

The disadvantage of using MAK Keys is they can be used once, and they are set to activate a specific number of devices. The count is pre-configured as a deal between Microsoft and Enterprise. Every time a device is activated using MAK, the total count drops by one.

It is possible that your PC was formatted, and you have lost your previous key, or when the admin gave you the key to activate, it already had exceeded the limit on the number of activation.

You should call in your System admin to get this resolved. And if you are the system admin and believe that the limit didn’t cross, you can call Microsoft support to get this resolved.

MAK keys are usually used on server devices or on computers where the chances of formatting or resetting are low. They also cost a lot less compared to others because of the one-time activation feature, and hence the restriction on activation.

If you receive a key that you doubt, and need to figure out the type of key, then you can use the slmgr /dli command. It will reveal if it’s Retail, OEM, or KMS, or MAK keys.

I hope you resolve the 0xC004C020 Activation error.
