In the event your computer Is not booting properly Into the Windows environment, or you're receiving error messages during the boot process and you've exhausted every troubleshooting option to no avail, It's time to do what's called a clean boot. This helps Identify Issues that're preventing Windows from starting normally. In this tutorial, I will show you how to perform a clean boot In Windows 10.
So what exactly Is a clean boot? In simple terms, It's disabling all startup applications and Microsoft Services (that're also scheduled to start), and attempting to boot Into the Windows environment as per It's normal state. If successful, then one or more of these entities are preventing Windows from loading as It should. You then enable each application and service one at a time, until you Identify the one that's causing the problem.
In other words, a clean boot allows your PC to boot with minimal startup applications, services and drivers. If It boots without error, then you know that one or more of these, Is causing Issues. So without further delay, let's get this tutorial started.
The first thing we'll do, Is disable all startup applications. Open Task Manager, select the Startup tab and then right-click each entry and hit Disable.
When you're done, the status of every startup application, should be Disabled as Illustrated below.
Now we'll disable every Microsoft Service that's scheduled to start. Firstly, open the Run menu, enter msconfig and hit OK.
Select the Services tab, click the Hide all Microsoft services checkbox, and then hit Disable All.
If your result looks similar to mine as per the Image below, hit Apply and OK.
You will be prompted to restart your computer, so do exactly that by hitting the Restart button.
In my case, I'm now waiting to see If the operating system boots Into the Windows environment. Obviously, the same will apply with yourself.
As you can see, It's successfully booted Into Windows with a minimal set of drivers, programs etc- confirmed by the missing network connection and audio functionality as arrowed below. I now know, that one or more of the startup applications or Microsoft services Is preventing Windows from loading.
Beginning with startup applications, go back to Task Manager as per Step Two above. Enable each application one at a time and reboot Windows (each time), until you find the problematic application.
Do the same with the Microsoft Services (as per Step Four above). Enable one, reboot your PC and enable another until the problematic Service that's preventing your computer from booting normally Is found.
When you've Identified the application and/or service that's causing the Issue, enable all startup applications and Microsoft Services- excluding the problematic ones. I've done exactly that, and as you can see, my operating system Is functioning as per normal.
As you've most likely realized, this may be a lengthy process to try and Identify exactly what's causing your operating system from booting correctly. If you've exhausted every other option to no avail, then a clean boot using the above methodologies, Is certainly worth doing. Just remember that It does come down to a process of elimination until the problematic application/service Is found.
