How to repair and restore Windows 10

Windows Microsoft

System Restore, Startup Repair, and System File Checker are three vital built-in Windows 10 tools for fixing software issues that cause slow performance, crashes, or solving errors that prevent your computer from starting up normally.

If your computer is encountering problems after updating or installing an app, System Restore can quickly revert your device to working order by restoring a previous image of your operating system prior to any recent changes.

If you're plagued with errors or sluggish load times when trying to start your machine, Startup Repair is a simple tool that can correct many boot-up bugs that get in your way.

Additionally, the built-in System File Checker tool for Windows 10 can find and repair (or replace) potentially corrupted or missing system files that may be impacting your laptop or desktop PC's performance or operation.

The following guide will focus on how you can use each tool within Windows 10, hopefully solving any issues you may be encountering with Microsoft's operating system. Read on to learn how to repair and restore Windows 10, or jump to the relevant topic using the links below.

How to repair and restore Windows 10

Method 1: Using Windows Startup Repair

If Windows 10 is unable to boot up and takes you to the login screen or the desktop, your first step should be to use Startup Repair. Here's how:

Step 1: Navigate to the Windows 10 Advanced Startup Options menu. On many laptops, hitting F11 as soon as you power on the machine will get you to the Windows 10 Advanced Startup Options.

Step 2: Once your computer has booted into the startup options menu, select Troubleshoot.

Step 3: Then click Advanced options.

Step 4: From here, click Startup Repair.

Windows will take anywhere from a few seconds to a few minutes to attempt to fix the problem. (It may not be able to.) If you don't actually have a startup problem, it will also say it can't fix the problem.

Method 2: Using Windows Restore

Step 1: Complete step 1 from the previous method to get to Windows 10's Advanced Startup Options menu.

Step 2: Click System Restore.

Step 3: Following an automated reboot, select your username and enter your password (if you use one).

Step 4: Select a restore point from the menu and follow the remaining prompts. If you find that you have no restore points, you can't use this method.

Method 3: Using Disk Scan (System File Checker)

Your Windows 10 problems may stem from a corrupt file. If you can boot into the operating system — even if you have to boot into safe mode — you should perform a file scan to check for problems.

Step 1: Type "cmd" (without quotations) into the main search box.

Step 2: Right click on Command Prompt and select Run as Administrator.

Step 3: Type "sfc /scannow" (without quotations) at the command prompt and hit Enter. The scan will take a while; but it should fix any corrupted files it finds.

Method 4: Reset Windows 10

If you want to get a clean start, free from rogue software and drivers, you usually don't need to do a full install. Instead, Windows 10 provides a built-in reset feature that takes your computer back to the way it was before you had any software, special devices, or data preloaded. (On a side note, if you're giving your computer to someone else, resetting is a good way to wipe it.)

Method 5: Reinstall Windows 10

If all else fails and you can't even reset your Windows computer, you can reinstall the operating system entirely. You won't even need an activation number or any proof of purchase, either.

Just make sure you have more than 4GB of space available, as that's how much space the file you'll download takes up. Here's how to reinstall Windows 10:

Step 1: Visit this page and click Download now.

Step 2: Once the file has downloaded, open the Media Creation Tool from your download folder.
