How fix Windows 10 blue screen errors (also known as blue screen of death)

How to troubleshoot blue screen during boot with desktop access
When you experience a Blue screen Of Death (BSOD) and you can access the desktop, the problem can be an outdated driver or missing update. Or it can also be an issue with a recently installed application, Windows update, or device driver.
How to install updates and drivers
You can make sure your installation of Windows 10 and drivers are up to date by following these steps.
Installing latest Windows 10 updates
Although the OS installs updates automatically, it's possible that an update may still be missing on your computer.
To check for updates on Windows 10, do the following:
Step 1. Open Start and click on Settings
Step 2. Click on Update & security.
Step 3. Click on Windows Update.
Step 4. Click the Check for updates now button.
In the case that you're getting a stop error because of an outdated device driver, you can do the following:
Step 1.Right Click windows icon to open the Power User menu.
Step 2.Click on Device Manager.
Expand the device causing the problem.
Right-click the device and select Update Driver Software.
How to troubleshoot blue screen during boot without desktop access
Other times, a BSOD will appear on Windows 10 after installing a new update or device driver, and you won't be able to get to the desktop to fix the problem.
Quick Tip: If you can't boot to your desktop, and you recently connected new hardware, such as an external hard drive, secondary monitor, or printer, try to disconnect any unnecessary hardware to see if that fixes the problem.
When this happens, you can use System Restore or Safe mode to troubleshoot and resolve the problem.
Fixing blue screen using Restore Point
If you can't access the desktop, let your computer fail to start at least three times to trigger the automatic repair environment, and then do the following:
Step1.On the "Choose an option" screen select Troubleshoot.
Step 2.Click on Advanced options.
Step 3.Click on System Restore.
Step 4.After your computer reboots, select your account and sign-in.
Step 5.Click Next.
Step 6.Usually, system restore points are automatically created when you install a new update, driver or app. You can also create a system restore point manually. Select the restore point created before the blue screen appeared
Step 7.Click Next.
Step 8.Click Finish to apply the restore point.
Once you complete these steps, the system restore will remove updates and drivers configured after the restore point was created, which can help to fix the stop error.
