Windows 7 came preinstalled on my computer, how do I find the product key?

The product key is usually located on the COA sticker attached to the bottom of your laptop or in the battery compartment. In some rare cases it can also be found in the memory compartment. For tower systems, look at the top or the side of the system unit. It looks like the following:

If the Certificate of Authenticity (COA) sticker is damaged or letters or not legible, you will have to consider the following options:

• Use a digital camera to capture a picture of the COA then enlarge it on your computer.

• If the COA sticker is damaged, then you would need to use the recovery partition to reinstall Windows 7, this will exempt the need to use the product key to activate your Windows 7 installation.

• If your recovery partition is not available or damaged, you should contact the manufacturer of your computer and request a recovery disc set you can use to reinstall Windows 7. They might charge a small shipping and handling fee. This will exempt the need to use the product key also.

• If none of the above options work or is not available, then its best you purchase a new Windows 10 license:

I bought a retail box copy of Windows 7 or Windows 8 or Windows 8.1; where do I find the product key?

For Windows 7, the product key can be located on a pamphlet in inside the Windows 7 box.

For Windows 8 or Windows 8.1, the product key can found on a small business size card inside the Windows 8 box.

I was running a premium business edition of Windows 7 such as Professional or Ultimate or Windows 8/8.1 Pro but the Media Creation Tool installed Windows 10 Home instead of Pro

If you performed a clean install using the Media Creation Tool it installs the specific edition based on the OEM Marker in the BIOS. So if the computer originally came preinstalled with Windows 7 Starter, Home Basic, Home Premium or Windows 8/8.1 Core/Single Language Windows 10 Home will be installed.

Workaround:

Upgrade to Windows 10 Pro using the following default product key:

VK7JG-NPHTM-C97JM-9MPGT-3V66T

Review instructions how to perform an Easy Upgrade using the default key:

After upgrading, proceed to enter the Windows 7 Professional, Ultimate or Windows 8 Pro product key.

Click Start > Settings > Update & security > Activation > Change the product key then enter the new product key then click Next to Activate

I had Windows 8.1 with Bing installed then used the Media Creation Tool to upgrade to Windows 10 Home but it is not activating.

Computers or devices running Windows 8/8.1 Single Language (SL) or Windows 8.1 with Bing should use the Microsoft TechBench website to download Windows 10 SL and use that to upgrade their computer. Your best course of action is to first try Rolling Back to Windows 8.1 with Bing then perform the upgrade properly.

When I upgrade a preinstalled (OEM) or retail version of Windows 7 or Windows 8/8.1 license to Windows 10, does that license remain OEM or become a retail license?

If you upgrade from a OEM or retail version of Windows 7 or Windows 8/8.1 to the free Windows 10 upgrade this summer, the license is consumed into it. Because the free upgrade is derived from the base qualifying license, Windows 10 will carry that licensing too.

If you upgrade from a retail version, it carries the rights of a retail version.

If you upgrade from a OEM version, it carries the rights of a OEM version.

Full version (Retail):

- Includes transfer rights to another computer.

- Doesn't require a previous qualifying version of Windows.

- Expensive

Windows 10 Serial Key Free Download

Upgrade version (Retail):

- Includes transfer rights to another computer.

- require a previous qualifying version of Windows.

- Expensive, but cheaper than full version

OEM :

OEM versions of Windows are identical to Full License Retail versions except for the following:

- OEM versions do not offer any free Microsoft direct support from Microsoft support personnel

- OEM licenses are tied to the very first computer you install and activate it on

- OEM versions allow all hardware upgrades except for an upgrade to a different model motherboard

- OEM versions cannot be used to directly upgrade from an older Windows operating system

What happens if I change my motherboard?

As it pertains to the OEM license this will invalidate the Windows 10 upgrade license because it will no longer have a previous base qualifying license which is required for the free upgrade. You will then have to purchase a full retail Windows 10 license. If the base qualifying license (Windows 7 or Windows 8.1) was a full retail version, then yes, you can transfer it.

From the Windows 10 end user license agreement:

b. Stand-alone software. If you acquired the software as stand-alone software (and also if you upgraded from software you acquired as stand-alone software), you may transfer the software to another device that belongs to you. You may also transfer the software to a device owned by someone else if (i) you are the first licensed user of the software and (ii) the new user agrees to the terms of this agreement. You may use the backup copy we allow you to make or the media that the software came on to transfer the software. Every time you transfer the software to a new device, you must remove the software from the prior device. You may not transfer the software to share licenses between devices.

Windows 10 Activation reports your license will soon expire.

This can happen for a number of reasons:

• You copied a Windows 10 Pro off the Internet (usually a volume license - organization - key) and changed on a Windows 10 Home installation. Windows 10 Pro is not free. If this is what you did, you will need to reinstall the previous edition or version you were running. You inadvertently installed the wrong edition.
  • The copy of Windows 10 you download and upgrade from will correspond with the edition of Windows you have installed, if it does not, this is why you might be experiencing problems activating:

• Windows 7 Starter, Home Basic, Home Premium, Windows 8.0 Core, Windows 8.1 Core will install Windows 10 Home
  

• Windows 7 Professional, Windows 7 Ultimate, Windows 8.0 Pro, Windows 8.1 Pro will install Windows 10 Pro

To find out if you have the right edition installed:

Click Start > Settings > Update & security > Activation > Edition.

If the edition of Windows 10 installed does not correspond with the edition of Windows 7 or Windows 8 you were previously running, then you need to reinstall the right edition.

Use the appropriate product key for the edition of Windows 10 you have installed.

Windows 10 Serial Key

If Windows 7 or Windows 8 came preinstalled, use that that product key to update the product key values.

or use one of the following product keys:

1) Enter the Windows 10 Home/Pro default key. (see list below)

Windows 10 Home: YTMG3-N6DKC-DKB77-7M9GH-8HVX7
Windows 10 Pro: VK7JG-NPHTM-C97JM-9MPGT-3V66T

Warning: please ensure you use the right product key for the right edition.

Click Start > Settings > Update & security > Activation > Change the product key then enter the new product key then click Next to Activate

Users who mistakenly entered a Volume License Key (VLK) and now want to activate using a consumer product key or license. They may encounter and activation error of 0x8007007B or 0xC004f210 or the product key enter error of 0xC004F050 or 0xC004E016.

You may try the workaround mentioned below and see if it helps.

*Important* - Do not follow these steps if:

- The device is in Deferred mode, meaning that the Activation page in Settings says to connect to the internet in order to activate.
- The device is intended to be used on a corporate network with a KMS server (not necessarily domain joined)
- The user is trying to enter a Windows 7/8/8.1 MAK key that is the same edition as the currently installed OS and seeing SL_E_EDITION_MISMATCHED (0xC004F210). The correct fix is for the user to install the published GVLK for the edition (https://technet.microsoft.com/en-us/library/jj612867.aspx) and then try to install the Windows 7/8/8.1 MAK key again.

Workaround:
If you confirmed they have attempted to apply a VLK to Consumer software, they are essentially changing their licensing. They need to get their system off the VL path and back on the Consumer correct path. This is the current workaround:

1) Enter the Windows 10 Home/Pro default key. (see list below)

Win 10 Home: YTMG3-N6DKC-DKB77-7M9GH-8HVX7
Win 10 Pro: VK7JG-NPHTM-C97JM-9MPGT-3V66T
Win 10 Home N: 4CPRK-NM3K3-X6XXQ-RXX86-WXCHW
Win 10 Home Single Language: BT79Q-G7N6G-PGBYW-4YWX6-6F4BT
Win 10 Home Country Specific: 7B6NC-V3438-TRQG7-8TCCX-H6DDY
Win 10 Professional N: 2B87N-8KFHP-DKV6R-Y2C8J-PKCKT

2) Check for the new error returned - they should now receive error 7001

3) Use their Windows 7 or 8 product key to complete the activation (Note: If they do not have a Win 7/8 key or we are not able to extract using CMD, they will need to purchase a 7/8 Key or a 10 license).
