How To Repair Windows 10

Perhaps Windows 10 won't start. Or maybe it boots, but crashes a lot. In either case, you need to fix the problem before you can use your PC. Here are a few ways to repair Windows 10.

Method 1: Use Windows Startup Repair

If Windows 10 won't even boot up and take you to the login screen or the desktop, your first step should be to use Startup Repair. Here's how:

1. Navigate to the Windows 10 Advanced Startup Options menu. There are many ways to get to Windows 10 Advanced Startup Options. On many laptops, hitting F11 as soon as you power on will get you there. Booting off an install disk and hitting Next then Repair will do the job too.

Once your computer has booted, you'll want to select Troubleshoot

And then you'll need to click Advanced options.

2. 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: Use Windows Restore

1. Get to Windows 10's Advanced Startup Options menu.

2. Click System Restore.

The computer will reboot.

3. Select your username.

4. Enter your password.

5. Select a restore point from the menu and follow the prompts. If you have no restore points, you can't use this method.

Method 3: Perform a Disk Scan

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.

1. Type "cmd" into the search box.

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

3. Type sfc /scannow at command prompt and hit Enter.

The scan will take a while and 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 which 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 from Scratch

If all else fails and you can't even reset your Windows computer, you can reinstall 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:
