Reinstalling Windows 10 can solve the following problems:

Windows is updated improperly.
The other methods fail to fix the issues on Windows.
The computer is running slowly.
The system is frequently crashed.

Before reinstallation, you should make these preparations:

Back up data – All programs and files on the partitions will be emptied during reinstallation. Please back up your important files beforehand.
Enough time – It takes a long time to reinstall the whole system. You should spare enough time for the operations.
Make association between Windows product key and Microsoft account – It is a way to verify and activate your system.

TipsAccording to Microsoft, if Windows 10 has been activated in a PC, it can be reinstalled without the product key in the same device.

How to link Windows product key with your Microsoft account:

Part 2: Back up/Transfer Data before Reinstallation

Next, we should make preparations for Windows 10 reinstallation. Since all contents will be emptied from the complete reinstallation process, we suggest you to create temporary backup files for these contents.

1. Upload to OneDrive

There are many backup ways, such as OneDrive. OneDrive, the cloud storage services introduced by Microsoft, supports users of Windows PC and phone to save and sync files. Through OneDrive, we can back up the important files, such as document, desktop and pictures. Now, it includes a free tier that offers 5GB of file storage.
How to back up with OneDrive:

① If you’re prompted to back up your important folders (desktop, documents, and pictures), select the prompt to start the folder backup wizard.

If you didn’t see the prompt or you already closed the wizard, select the white or blue cloud icon in the Windows notification area, and then select [More] > [Settings], then [Backup] > [Manage backup].

Windows 10 offers a simple reinstallation way. Users don’t have to download the ISO files or use the boot media but quickly factory reset the system to the original status. But as many users reported, it cannot solve some issues on the computer. If it is not a solution to troubleshoot, you shall try the second method.
Steps:

① Get [Windows Settings] started from the Start menu. Then, select [Update & Security].

Method 2: Reinstall Windows 10 from Boot Media

This method is about completely erasing the disk and installing the new Windows 10 edition through boot media. First, you should prepare an external device, such as USB or DVD. By the way, this method is suitable for the unbootable computer.
Check if you get these conditions:

Connect the computer to the network.
Prepare an external device, like USB, DVD or hard drive with at least 8GB.

Step 1: Create installation media
Here are two points for creating a new installation media:

You shall check whether you’ve backed up the important data to the other storage devices (i.e. USB or SD card) or to OneDrive. It is noted that you not save the backup files to the device which is going to be installation media.

You shall prepare a blank USB flash drive with at least 8GB of space or blank DVD (and DVD burner) if you want to create media. We recommend using a blank USB or blank DVD, because any content on it will be deleted.

Steps:

① Download the media creation tool from the Microsoft official site (URL: https://www.microsoft.com/en-au/software-download/windows10). Then, click on [Download tool now].

Step 2: Reinstall Windows 10
Steps about how to reinstall Windows through the boot media.

① Insert the installation USB when the computer is off. It is noted that the USB shall be inserted into the rear interface in desktop computers and the all-in-one PCs, and into the USB 2.0 interface in the laptops.

② Restart your PC. If your PC does not automatically boot to the USB or DVD media, you might have to open a boot menu or change the boot order in your PC’s BIOS or UEFI settings. To open a boot menu or change the boot order, you’ll typically need to press a key (such as F2, F12, Delete, or Esc) immediately after you turn on your PC.

Method 3: Back up Windows 10 with Renee Becca

Data on the Windows partitions will be reset after the reinstallation. Therefore, you should install the programs and change the settings again. That is quite time-consuming. What’s more, it is still very difficult for newbies to reinstall the system. We recommend Renee Becca, an easy-to-use tool that reinstalls the system merely through a USB flash drive, without any data lost. Users can back up the whole Windows 10 system and then recover the system to the other computers. Through this method, you don’t need to reinstall the drivers, programs and reset the system.
