How to highlight the scroll button on the scroll bar?
I want to make it bright

:)

 

My Start Button is present, but has changed color.

Hello,

Thank you for posting in Microsoft Community, we appreciate your interest in Windows 10.

I understand your concern that start button and apps color changed also you are unable to access Windows Defender.

This issue might be due to corrupted or missing System files.

I suggest you to perform the below troubleshooting steps and check.

Method 1: Run the SFC.

System File Checker is a utility in Windows that allows users to scan for corruptions in Windows system files and restore corrupted files.

Follow the below steps:

• 
  Right click on the Start button, click on
  Command Prompt (Admin).
  
• 
  Type “sfc /scannow” without the quotes and hit
  Enter.
  
• 
  After the scan, restart the computer and check for the issue.
  

Also, I suggest you to check for the Windows updates and see if you are able to access Windows Defender.

Steps:

• Press Windows key and type Windows update.
• select check for updates and install all the pending updates.

Hope it helps. Kindly update the status of the issue, we will be happy to help you.
