Free Windows 8.1 Product Keys

If you want Windows 8.1 to run smoothly on your computer, you have to collect a working product key anyhow. It is a 25-character code that verifies the copy of your Windows. The code must be unique and it looks like XXXXX-XXXXX-XXXXX-XXXXX-XXXXX. The main purpose of this activation code is to verify that the copy hasn’t been used on devices more than what the subscription covers.

If you don’t have a genuine Windows 8.1 product key, you won’t be able to run the OS on your computer. There are two ways you can get a product key for your Windows. Either purchase the product from a local retailer or the official website or find a working activation key. If you buy a laptop with Windows 8.1 preinstalled, the activation key will be written at the back of your device.

Find Windows 8.1 Product Key

These are the following places where you can find a working and genuine Windows 8.1 product key-

  • If you purchase a computer with Windows version 8 pre-installed, you will find the activation key at the back of your computer in a sticker
  • In case you cannot see the sticker, then ask your retailer to find it for you
  • But if you purchase the Windows copy on a CD, you will find the activation key at the back of the retail card
  • When you purchase your Windows copy online, you get the activation code in your email. Along with the activation key, you receive your billing information, order number, and a link to Windows 8.1 installer
  • If you don’t have a serial key to activate your Windows, you can use a free one from this post.
  • If you have lost your product key, you can use software available online to retrieve it. For example, PassFab Product Key Recovery is useful.

Activate Windows 8.1 (No Product Key Needed)

A genuine product key is necessary to activate your Windows version. But if you can’t afford one valid activation key, you can still activate Windows. However, these methods work depending on a few conditions such as your internet connection, system processor, etc. So, in case you are unable to activate Windows without a product key, you will have to depend on a Windows 8.1 serial number.

Upgrade it to Windows 8.1

If you are running Windows 8 right now, then you can upgrade the version to Windows 8.1. However, before we talk about how to start the process, here are a few things you have to take care of-

And when you make sure all of the previous requirements, follow the steps given below-

  1. Open the Windows Store on your Windows 8 computer
  2. Locate the update feature
  3. Select Update and click on Download
  4. Your system will now download the update files and install them on your computer in the background
  5. When the process is done, restart your PC
  6. When the update Windows option pops up again, select the Use Express Settings option
  7. Use your Microsoft account credentials and log in to your email
  8. Reinstall the Microsoft Windows applications.
