Some Common Sense or Question about Microsoft Win10 Key Activation Code

Microsoft will end support for Windows 7 in July 2020. What does that mean? Computers running Windows 7 will not receive security updates. Users must use a product key to upgrade to Windows 10 in order to get a new security update.

Below is a Windows 10 pro product key, not an update key!

Windows 10 License Types

Retail Key:

  • Pros: The retail key can be purchased through Microsoft’s official online store or extracted from MSDN’s vs subscription account. Typically, a key can activate only one device, but there are versions that activate 5 PCs.
  • Cons: The price is very high.

MAK Key:

  • Pros: In general, this kind of key is a batch purchase from Microsoft, the number of activations can reach thousands of times. In some cases, Microsoft also resets the number of times the key is used, which is to resuscitate it.
  • Cons: The cheap key on the market (amazon/ebay) basically belongs to this category.

OEM key:

  • Pros: The key that the manufacturer purchased directly from Microsoft to activate the pre-installed Windows system device. This key is usually tied to the motherboard and can be activated indefinitely on the same computer.

KMS key:

  • Pros: The KMS key needs to be connected to the KMS activation server. When the client enters the KMS key, it automatically looks for the KMS activation server in the network and automatically activates it. This key is valid for 180 days and the client looks up the KMS server again before it expires to activate it.
  • Cons: The disadvantage is that reinstallation is not supported and there is a security risk to the system.

The keys we use are generally MAK or OEM. View the differences in system activation information (product key channel) for several different types of keys:

Common questions about the product key:

Q: Are these Keys permanent? Will activation be revoked?

As long as it is not the KMS key, there is no need to worry about the activation being revoked.

Q: Does it support reinstallation?

If the activation status displayed in the system settings is as shown below, it is only one-time activation (re-reinstall is not supported)

Q: Are these Keys genuine?

In terms of effect, as long as it can be successfully activated, it is Microsoft’s own Key. It can be understood as a genuine key.

At the legal level, the definition of a genuine is twofold:

  • Legal source of channels
  • Legal use

Q: Why is there a security risk in KMS activation?

The KMS key is for enterprise users. Because the number of PCs in the enterprise is hundreds or thousands, it is impossible to activate one by one. In this case, the enterprise needs to purchase a volume product key (Volume Key, the activation channel is Vol). Then, build and configure a KMS server, and install the KMS client on each PC for volume activation and management.

In other words, the system no longer belongs to you, but to a team/manager. The administrator can remotely activate/deactivate your PC, and even execute some operational instructions on your PC. Even more frightening is copying data, gathering information, and even bulk resetting all managed Windows 10 client systems.
