Easiest ways to Reset Windows 10 and Reinstall From Scratch

Windows 10 is still microsoft wondows,If your computer isn't running the way it should, you're getting strange errors or you just want to return it to its default state, Windows 10 has your answer. The operating system provides a number of options that let you restore your computer to an earlier state. Here's how to reset your PC in Windows 10.

Why is that? With Windows 10 Microsoft is switching its operating system (OS) to a mandatory update process that is similar to Android and OS X. Rather than releasing major OS versions that have to be purchased separately every couple of years, the OS is updated internally on a regular basis. In other words, if you’re running Windows 10, you will always be running the latest and safest version of Windows.

While this process reduces friction and increases safety, it can also introduce or compound system issues. That’s because, by design, new stuff keeps getting added and you always keep your personal files, settings, and applications. Fortunately, you have a few options to flush out sour system files and remove irksome applications that managed to sneak in.
We show you how you can get a fresh Windows 10 installation with as little effort as possible. Be sure to create a backup of your personal files before you proceed with any of these solutions.

#1.Reset Windows 10

Windows 10 comes with a reset feature similar to Windows 8. A system reset essentially gives you a fresh Windows installation, although in Windows 10 you have the option to keep your personal files.

To reduce the storage footprint of Windows 10, Microsoft redesigned the Reset feature “to rebuild the operating system in place using runtime system files.” This means the Reset feature draws on a (potentially customized) recovery image on your system drive (typically found under C:\RecoveryImage\) to initiate a fresh installation.
The beauty of this solution is that Windows does not need to download any files to initiate the setup and you don’t have to provide installation media, either. On the other hand, manufacturers can provide a custom system image for the Reset feature and inject bloatware.
To reset your computer from within Windows 10,

Navigate to Settings. You can get there by clicking the gear icon on the Start menu.
Select "Update & security"
Click Recovery in the left pane.
Windows presents you with three major options: Reset this PC, Go back to an earlier build and Advanced startup. Reset this PC is the best option for starting fresh. Advanced startup lets you boot off a recovery USB drive or disc and "Go to an earlier build" is made for Windows Insiders who want to roll back to a previous version of the OS.
Click Get started under Reset this PC.
Click either "Keep my files" or "Remove everything," depending on whether you want to keep your data files intact. Either way, all of your settings will return to their defaults and apps will be uninstalled.
Select "Just remove my files" or "Remove files and clean the drive" if you chose to "remove everything" in the prior step. Cleaning the drive takes a lot longer but will make sure that, if you are giving the computer away, the next person will have a hard time recovering your erased files. If you are keeping the computer, choose "Just remove my files."
Click Next if Windows warns you that you won't be able to roll back to a prior version of the OS.
Click Reset when prompted.
Windows will then restart and take several minutes to reset itself.
Click Continue when prompted.

Note: If your issues started after upgrading Windows 10, either from a previous Windows version or an earlier build, rather than reset or reinstall Windows, you can also try a downgrade. This works because every time Windows installs a new version, it keeps a copy of the previous one in a folder called Windows.old. Press Get started under the respective option to go back to that previous Windows installation.

#2. Refresh Windows 10

In Windows 8, a Refresh was a Reset, but with keeping your personal files. The Refresh option relied on a recovery image provided by the manufacturer and would thus re-install bloatware that came with the computer. As we’ve learned above, you can keep your files when you do a Reset in Windows 10. And seemingly just to confuse you further (or finally simplify things), Microsoft released a Refresh tool for Windows 10 that works slightly different than what we know from Windows 8.

The Windows 10 Refresh Tool (download here) requires an Internet connection and approximately 3 GB of available storage space because it downloads the latest version of Windows 10 before refreshing your PC. This ensures that your fresh Windows 10 installation will be completely free of manufacturer bloatware, though you will still find Microsoft bloatware.

A Windows 10 Refresh will not re-install any of your applications and to re-install hardware drivers, you may have to run Windows Update under Settings > Update & security > Windows Update after the installation has completed. As with the Reset option, you can choose to keep your personal files. If you would like to back up and restore your Windows 10 settings and apps, check out our respective article.

Note: At the time of writing this article, the Refresh tool comes with several caveats, such as only working on the latest build of the Windows 10 Insider Preview. It is expected to be fully functional with the upcoming Anniversary Update, expected in late July 2016.

#3. Use Installation Media

This is an advanced method you can use in place of the Reset or Refresh options described above; for example, if your PC won’t boot or your Internet bandwidth is severely limited. Maybe you bought a copy of Windows 10 that came with installation media or you were wise enough to create your own Windows 10 installation media using the Windows Media Creation Tool.

If you need to re-install a particular version of Windows 10, you may be able to download the respective ISO file free from Microsoft and create your own install disc using Rufus.
Before you can proceed with the Windows 10 setup, boot into the UEFI / BIOS and make sure the boot order prioritizes booting from your installation media, i.e. your CD/DVD or USB drive, rather than booting from the system drive.

When your BIOS settings look good, insert your installation media and let your computer boot into the Windows setup. From here, follow the on-screen instructions and enjoy a fresh installation of Windows 10 in no time. Unfortunately, you will eventually have to run Windows Update to bring your system up to speed again.

Tip: We recommend keeping your installation media fresh by regularly updating the files with the latest updates. Otherwise, Windows Update might slow you down with massive downloads and multiple installation cycles.

#4. Use a System Image

The methods above have one huge linke all your personal settings and installed applications. To avoid this scenario, we recommend to regularly prepare an image of your entire system.
We have previously covered how to create an ISO image of your Windows system. An alternative to the native Windows solution is to use a free third-party tool like Macrium Reflect. We have covered this tool in our article on moving Windows from a HDD to an SSD. It lets you create both rescue media and an entire system backup.

In Windows 8 and 10, Choose an option screen appears instead. Click or tap Troubleshoot.
If your device's system drive is encrypted with BitLocker, you need to type in the recovery key first. BitLocker recovery keys are stored in your OneDrive/SkyDrive account, or you might have backed them up onto a USB stick (insert the stick then).

Click or tap Advanced options in Troubleshoot screen.
In Advanced options screen, click or tap System Image Recovery.

If your computer has multiple user accounts, you need to choose the one with administrator rights and type password for the account.

Click or tap to select the correct operating system to re-image. In this example, choose Windows 10 in the System Image Recovery screen.
Re-image your computer window opens in Windows 7, 8 and 10, and the following process is exactly the same even in Windows 8.1. If you want to restore the latest available system image (the date and time of the image are displayed in Date and time: field below), accept the default selection and click Next.

Note: Rather than regularly creating full system images, you can also turn on System Restore in Windows 10 (which is off by default). We’ve covered that method in our ultimate Windows backup guide. Briefly, press Windows key + Q to launch the search menu, find Create a restore point, select your system drive, click Configure…, select Turn on system protection, and click OK.

You will need at least 20 GB of available storage and we recommend that you manually create your first system restore point.

Keep Windows Fresh

Whatever you do, never restore your computer to factory settings using the manufacturer’s system image. Use one of the methods above to make Windows 10 as good as new. If you can’t decide which one to go with, follow our guide on whether to refresh, reset, restore, or reinstall Windows.
