Windows 10 keeps freezing randomly for no apparent reason

Hello Kawan,

Thank you for posting your concern in Microsoft Community and welcome to the Windows 10 Family.

From the description provided, I understand that you are facing slow performance issues after upgrading to Windows 10.

Before proceeding as an initial recommendation, please check for the amount of hard disk space remaining, as the available free space is also responsible for Windows to run at optimal level of performance. Also, ensure to install any pending
updates and also update all device drivers from Device Manager.

Now please follow the below methods and check for the results.

Method 1

• Place the computer in a Clean Boot state and check if there are any third party applications to be causing the slow down.

1. To disable all non-Microsoft services consult the article called
Clean Boot.
Follow: https://support.microsoft.com/en-us/kb/929135

Note: After troubleshooting, refer to this section "How to reset the computer to start normally after clean boot troubleshooting"

Disclaimer: A clean boot is performed to start Windows by using a minimal set of drivers and startup programs. This helps eliminate software conflicts that occur when you install a program or an update or when you run a program in Windows. You may
also troubleshoot or determine what conflict is causing the problem by performing a clean boot. You must log on to the computer as an administrator to be able to perform a clean boot. Your computer may temporarily lose some functionality when you perform a
clean boot. When you start the computer normally, the functionality returns. However, you may receive the original error message, or experience the original behavior if the problem still exists. If the computer is connected to a network, network policy settings
may prevent you from following these steps.

2. To disable any 3rd party unwanted startup programs in Windows 8 and above, follow:

(Applies to Windows 10 as well)

• Try Autorun and disable any start-up programs you don't need.

Follow the below steps:

1. Type troubleshooting in the search bar.

2. Select Troubleshooting.
