This could also be the case if you took advantage of the free Windows 10 upgrade offer on a PC running a Home edition of Windows 7 or Windows 8.x. In either case, the upgrade takes just a few minutes. USB flash drive Insert the USB flash drive you just created into a free USB slot on the PC you want to upgrade. Then open File Explorer (Windows Explorer in Windows 7) and double-click Setup to. Press Windows key+R to open the Run box, enter the command rstrui, and press Enter. If you see a message like the one shown here, click System Protection to open the System Restore settings, click. Upgrade from Windows 7 to Windows 10 for free by following these simple steps, now that support for Windows 7 has ended. But in 2017, Ed Bott of CNET sister site ZDNet reported that the free.

Looking for a new laptop that won't break the bank? Here are a selection from a variety of manufacturers, with prices starting at only $230.

If you purchase a new PC with Windows 10 Home preinstalled, prepare to be annoyed. This down-market edition (maybe we should just call it Windows for Cheapskates) doesn't have the features you need for getting real work done: Remote Desktop server access, BitLocker disk encryption, group policy support, and control over when updates get installed, just for starters.

You could pay $99 for an upgrade, but before you reach for your wallet, consider a less expensive option.

Do you have an old product key from Windows 7 Pro, Windows 7 Ultimate, or Windows 8/8.1 Pro lying around? Those keys can be reused to enable an upgrade from Windows 10 Home to Windows 10 Pro, potentially saving you the upgrade fee. In fact, you can use a product key from any of these older Windows versions to perform a clean install or to upgrade to Pro.

It's worth rummaging through your garage, storeroom, or email archives to see if you can locate one of those old keys. Maybe you still have a key for one of the heavily discounted upgrades to Windows 8 Pro that Microsoft offered in the first few months after that product's ill-fated launch in 2012.

Or perhaps you have a shrink-wrapped retail copy of Windows 7 Professional or Ultimate, where the license associated with the product key is no longer in use.

Best of all, you only need to use the older product key one time. After you complete the upgrade from Windows 10 Home, the Windows 10 Pro digital license is attached to the specific hardware you just upgraded, allowing you to reinstall that edition of Windows on that hardware anytime, without the need for a product key.

This scenario worked during the early Windows 10 upgrade program, and after some testing and multiple reports from independent testers worldwide I can confirm that it still succeeds in 2021, more than five years later.

Microsoft first made this option available in Windows 10 version 1511. Since then, they have simplified the process dramatically.

I've been testing upgrade/activation scenarios on a wide variety of hardware over the years to see how things work. Here's the scoop.

UPGRADING A NEW PC FROM HOME TO PRO

Let's say you buy a new PC with Windows 10 Home installed by the OEM. Some vendors offer an upgrade option as part of the purchase, but many PCs sold in the retail channel are preloaded with Home edition.

This could also be the case if you took advantage of the free Windows 10 upgrade offer on a PC running a Home edition of Windows 7 or Windows 8.x.

In either case, the upgrade takes just a few minutes. Start at Settings > Update & Security > Activation, where you should see a screen that looks something like this:

If you don't have a Pro product key and you want to buy one, you can click Go To The Store and purchase the upgrade for $100. Easy.

But if you have a product key for Windows 10 Pro, Windows 7 Professional or Ultimate, or Windows 8/8.1 Pro, there's a less expensive option: Click the Change Product Key link and enter that 25-character key here.

After entering the product key, follow the prompts to perform the upgrade.

You'll see a succession of progress screens and your system will restart. After the upgrade completes, you should see a Success notification. Check the Activation screen again to confirm that you're now running Windows 10 Pro.

CLEAN REINSTALL

After you've successfully performed a Home-to-Pro upgrade, you can file that product key away. Your upgrade is now a digital license, attached to your unique hardware. If you perform a reinstallation of Windows, Microsoft's activation servers will recognize the hardware and activate Windows 10 automatically.

I have tested this scenario multiple times on hardware that originally shipped with Windows Home and was upgraded to Windows 10 Pro. After the upgrade was complete, I used a bootable USB flash drive containing Windows 10 setup files to reinstall a clean copy of Windows 10 Pro, skipping the option to enter a product key as part of setup, as shown below. When prompted, be sure to choose Windows 10 Pro as the edition to install.

When setup was complete, I signed in and checked the activation status (Settings > Update & Security > Activation). The system was properly activated, because Microsoft's servers recognized the hardware and used the digital license.

CLEAN REINSTALL, WITH EDITION UPGRADE

The one gotcha in this series of scenarios comes when you have a system that includes digital licenses for both Windows 10 Home and Windows 10 Pro. In that scenario, you can inadvertently restore Windows 10 Home.

This happened recently when I used a recovery image to reinstall Windows 10 on a Surface Pro PC that had originally shipped with Windows 10 Home and had been upgraded to Windows 10 Pro. Not surprisingly, using the recovery image gave me an installation of Windows 10 Home.

If that happens to you, don't bother searching for the product key you used to upgrade. Instead, use Microsoft's generic product key to force the upgrade.

Go to Settings > Update & Security > Activation and click Change Product Key. Next, enter the default Windows 10 Pro product key:

VK7JG-NPHTM-C97JM-9MPGT-3V66T

Follow the prompts to upgrade from Home to Pro. Because your hardware already has a digital license for the Pro edition, it will activate automatically.

That generic product key isn't magical, of course. If your hardware doesn't already have a Pro license, you'll get an activation error and you'll need to supply a proper product key or pay for an upgrade.

A little preparation can speed up the process tremendously.

For longtime PC owners, the clean install is a time-honored ritual, a way to restore an old PC to new life and instantly resolve annoyances caused by third-party software.

I have gone through this process many times through the years, sometimes with brand-new, freshly unboxed PCs, and other times renewing an older PC with a freshly formatted system drive. After all this time, I've developed a checklist to ensure that I don't miss any key steps along the way.

This post is the latest full update to the original version I published five years ago. It incorporates changes you'll encounter when using Windows 10 version 20H2 and later.

I just ran through this process again with a five-year-old desktop PC, replacing the SATA SSD with a modern NVMe module in a PCIe Gen3 x4 adapter. The entire process took less than an hour, and the difference in performance was as impressive as the original upgrade from hard drive to SSD was five years ago. If you want to do the same with your older PC or laptop, follow this checklist.
