If you have a Windows 7 or 8 computer, you have until July 29 to upgrade it to Windows 10 for free. While your data, apps and most of your system settings will remain intact, upgrading tends to adversely affect performance.

This post will show you how to change that and get a clean install of Windows 10 onto your computer. This is possible both after you've already upgraded to Windows 10 and before, when your computer still runs Windows 7 or 8.

Important note: You can't get a fresh system install without all of your apps and possibly some personal data being erased, so make sure to back up all of your important information before you begin this process. If you want to learn more about preparing your computer for Windows 10 (including how to backup), check out this post.

For a system already running Windows 10

How To Reinstall Windows 98

If your computer already runs Windows 10, the easiest way to refresh the machine is to reset it.

Step 1: From the Windows 10 Start Menu, click on Settings.

Step 2: On the Settings page, click on the button that reads Update & security.

Step 3: Now on the update and security page, click on Recovery, then under Reset This PC,click on Get Started.

Step 4: Choose the provided option to Remove everything. Alternatively, you can choose to retain your personal files (such as those in the Desktop and Documents folders) which will keep the files in your profile intact.

Note that the last option, Restore factory settings, is only available in certain machines and will reinstall the original Windows system that was on your computer when you bought it. You don't want to choose this option, unless your computer originally came with Windows 10.

Step 5: You will be presented with the option to Just remove my files or to Remove files and clean the drive. Basically, if you intend to keep the computer for yourself, pick the first option. If you intend to give it away or sell it after the reset, choose the second option, which will take much longer to complete.

After choosing an option, click on the Reset button and that's it. The computer will restart and after somewhere between 10 minutes to half an hour, or maybe longer depending on the speed of the machine, you will have yourself a computer with Windows 10 freshly installed. Note that resetting your machine in this way means you'll lose the option to roll back to the previous Windows.

For Windows 7/8 machines

If your computer still runs Windows 7 or 8, you want to avoid upgrading using Windows Update. Instead make yourself a Windows 10 installation disc. I prefer using a USB flash drive (thumb drive) since it works with all computers, including those without an optical drive. You'll need a drive that's 3GB or larger. Here are the steps.

Step 1: Go to Microsoft's Windows 10 download page and click on Download tool now to get the latest media creation tool.

Step 2: Run the downloaded tool, choose Create installation media for another PC then click Next.

Step 3: In this step, you select the Language, Edition and Architecture for Windows 10, then click Next.

Note that the N version of Windows 10 is for some European countries and will not include Windows Media Player. Read more about these specifications here. If you choose to make the installation media for both 32-and 64-bit Windows, you will need a thumb drive that has at least 6GB of storage space. If you intend to install Windows 10 on the current computer, you can check the Use the recommended options for this computer box.

Step 4: Choose USB flash drive.

Step 5: Insert the flash drive into the computer's USB port and click Next. After the drive is selected the tool will start downloading Windows 10. Depending on the speed of your internet connection, the download can take anywhere from a few minutes to a couple of hours. Once the download is done, the tool will takes another few minutes to turn the flash drive into Windows 10 installation media. You then can use this flash drive to upgrade or install Windows on any computer.

Step 6: Insert the installation media flash drive into a computer running Windows 7 or 8 that you want to upgrade. Open the drive in Explorer and double click on the Setup file. The upgrading process will start.

Step 7: After a short preparation, including checking for updates from the internet and asking you to agree to terms and conditions, you will be greeted with the Ready to Install dialog. Click on Change what to keep.

Step 8: In the next step, you can choose to keep Nothing (so that you'll have a truly fresh Windows 10 install), Keep personal files only (your documents, music, photos and so on will remain intact) or Keep personal files, apps or Windows settings (you will not have a clean installation of Windows 10). After that click Next.

Follow the rest of the installation and once it's done, if you have pick the option to keep nothing or just personal files, you will have yourself a clean installation of Windows 10 on your machine.

For a custom-build computer (advanced users)

If you've built your own computer, you can install Windows 10 on it using the flash-drive creation method in the section above. Choose to boot the computer from the flash drive and the installation process will start. Note that this method is quite involved, though self-explanatory, so make sure you know what you're doing (or are willing to learn a few new things).

Also note that installing Windows 10 fresh on a computer by booting from the installation media will require you to buy a new Windows 10 license. If you do this before July 29, you can use a Windows 7 or 8 license to activate Windows 10.

Good luck!

The Windows 10 upgrade process drags old files, settings, and programs from your previous Windows system to your new one. Microsoft allows you to get an entirely fresh system by performing a clean install.

This is particularly useful if you’ve purchased a new Windows 10 PC and it includes manufacturer-installed bloatware you don’t want. Or, you may need to perform a clean install on a computer without an existing Windows system after installing a new hard drive. Of course, you’ll miss out on the good pre-installed apps, like the free DVD player program that comes with many PCs. However, you can always install VLC to get DVD playback or use one of the more fully featured Windows Media Center alternatives.

Previously, Microsoft forced users to upgrade to Windows 10 before they could start fresh and do a clean install–which was annoyingly complicated and time-consuming. Now, things are much easier, since you can activate Windows 10 with a Windows 7, 8, or 8.1 key.

Option One: Create Installation Media and Install Windows from Scratch

The classic method of performing a clean install is still our go-to option with Windows 10. You just need to download and create installation media, either on a DVD or a flash drive, and install it from there.

Download the Windows 10 media creation tool from Microsoft. This tool will download the correct Windows 10 installation files for your system, and help you create an installation DVD or flash drive. Start it up and select the “Create installation media for another PC” option to create installation media.

Be sure to select the correct type of installation media for the copy of Windows 10 that’s licensed for your PC — Windows 10 Home or Professional. (If “Windows 10” is the only option, you can safely use that and it will detect what version you want.) You should also choose your language and select whether you want the 32-bit or 64-bit version of Windows here. Most people will want the 64-bit version, but you can create installation media that includes both, and the installer will automatically select the most appropriate one when you use it to install Windows on a computer.

Install Windows 10 from the installation media like you would any other operating system. Restart your computer with the USB drive or DVD inserted, and boot from that device. This may require you change a setting in the BIOS, access a boot menu, or use the “Use a device” option in the advanced startup options on a modern Windows 8 or 10 device that includes UEFI firmware instead of the traditional BIOS. Select “Install Now” once the Windows installer starts.

Next, you’ll see the activation screen. What you do here depends on your situation:

• If you’ve never installed and activated Windows 10 on this computer before, you’ll see the activation screen. Enter your Windows 10 key here. If you don’t have one, but you have a valid 7, 8, or 8.1 key, enter it here instead.
• If you’ve ever installed and activated Windows 10 on this computer before, click “I don’t have a product key”. Windows will automatically activate once it’s installed.

The second situation works because of how Windows 10 activates PCs. When you install and activate Windows 10 on a system for the first time, the installer confirms that you have a “genuine Windows” system installed and registers your hardware with Microsoft’s servers. After that, you shouldn’t have to enter that key again on the same PC–Microsoft will recognize your hardware the next time you install Windows 10 on that machine, confirm it’s registered, and automatically activate itself.

Go through the setup process normally until you see the “Which type of installation do you want?” screen. Select the “Custom” option to ensure you’re performing a clean install and not an upgrade install.

Partition your system drive however you like. If you just have a single Windows partition, you can tell the installer to overwrite it. If you have many partitions, you could delete them all and tell Windows 10 to install itself in the unallocated space.

After you log into your new, cleanly installed Windows 10 system, it should automatically activate itself after you connect to the Internet.

To ensure it activated correctly, open the Start menu and click on Settings. click the Update & Security button, and go to the “Activation” tab.

Verify that you see “Windows is activated” here. Also, note the edition of Windows 10 you have installed — either Windows 10 Home or Windows 10 Pro. Most people will receive the Home edition as part of the free upgrade from 7 or 8, but you’ll get Windows 10 Pro if you previously had a Professional edition of Windows 7 or 8 installed.

When we reinstalled Windows 10 Pro on our computer, it activated immediately. But, if Microsoft’s activation servers are overloaded, so it may take some time before your system activates. If it’s not activated, you may see information here that can help you activate.

Some people report having to reboot several times, while others have just waited. The following command can force an activation to occur if it’s not happening automatically after going through the steps above. First, open an Administrator Command Prompt by right-clicking the Start button or pressing Windows Key + X and selecting Command Prompt (Admin). Type the following command and press Enter:

slmgr.vbs /ato

Many people report having to run this command several times. if you see an error message, try rebooting and running it again, wait and run it again, or just wait and let Windows activate automatically. Microsoft’s servers may be overloaded at the moment you’re trying to activate.

Option Two: Perform a Reset and Remove Everything

If you’ve already upgraded to Windows 10 and want a fresh install, there’s an easier method. You can use the Reset feature to reset your Windows 10 system back to a fresh state. If you installed Windows 10 yourself, this should give you a fresh Windows system in no time.

There are a few caveats, however: this method isn’t ideal for every situation. If you purchased a computer that came with Windows 10, for example, this will likely bring back the bloatware that came with your Windows 10 PC. (There’s a way around this, but we’ve yet to test it ourselves.)

In addition, some people have reported that it won’t fix some system corruption issues, in which case you’d want to perform a real clean install using Option One above.

To reset your Windows 10 PC, open the Settings app, select Update & security, select Recovery, and click the “Get started” button under Reset this PC. Select “Remove everything.” This will wipe all your files, so be sure you have backups.

Microsoft’s free upgrade offer depends on your PC’s hardware so it may not activate properly if you’ve swapped out hardware inside your PC. You may need to call Microsoft and complete the phone activation process, explaining what happened, if you changed the PC’s hardware after taking advantage of the offer. The phone support line can give you an activation code that will allow you to activate Windows 10, even if it won’t activate automatically. However, you may have to provide additional information.

Technically, the free Windows 10 upgrade (as well as OEM copies of Windows and pre-installed copies of Windows 10) aren’t supposed to be transferred to a separate PC. But often, the phone activation process will let you do it anyway, so it’s worth a shot.
