Microsoft Security (Windows Defender) might show you an error that reads, An error has occurred in the program during initialization. If this problem continues, please contact your system administrator. Error code: 0x80073b01.
We do know that the error is most likely a conflict with another security application or corrupted system files. Try the following steps to resolve this error.
1: Microsoft Security Error 0x80073b01 - Uninstall Other Security Software
If you have third-party security software, uninstall it if that's a possibility.
However, we know this isn't a solution for many security-conscious people. Instead, check for updates to your software and Windows Updates. Your third-party security software most likely will find a way to fix the problem, so they don't lose you as a customer.

3: Microsoft Security Error 0x80073b01 - Run System File Checker
Windows 10, Windows 8.1, or Windows 8 users will need to first run the Deployment Image Servicing and Management (DISM) tool before running the System File Checker.

You will need to first open the Command Prompt or PowerShell as administrator.
Type in DISM.exe /Online /Cleanup-image /Restorehealth and press enter. This may take a few minutes.
All you need to do is type in sfc /scannow and press the Enter key.
System File Checker will now scan for and replace files from the Windows cache, typically located at C:\Windows\System32\dllcache.
