I keep getting an error at start up SecurityHealthSystray \\?\C:\Windows\System32\SecurityHealth\1.0.2303.28002-0\SecurityHealthSSO.dll bad image

Hi, Eahrend. I'm sorry to hear you're having this problem, and I hope I can assist you to find a satisfactory solution.

Here are a few additional suggestions you can try:

Run the System File Checker (SFC) offline: You can try running the SFC scan from the Windows Recovery Environment (WinRE) to ensure a more thorough scan. Boot your computer from a Windows installation media, select your language preferences, and then click on "Repair your computer." Choose Troubleshoot > Command Prompt, and then run the sfc /scannow /offbootdir=<drive letter of Windows installation>:\ /offwindir=<drive letter of Windows installation>:\Windows command.

Perform a Windows Startup Repair: You can try using the Startup Repair feature in the Windows Recovery Environment (WinRE) to fix any startup-related issues. Follow the same steps as above to access WinRE, and then choose Troubleshoot > Startup Repair. Let the process complete and see if it resolves the issue.

Perform a System Restore: If you have a restore point created before the issue started occurring, you can try performing a System Restore. Boot your computer into WinRE, select Troubleshoot > Advanced options > System Restore, and follow the on-screen instructions to restore your system to a previous working state.

Perform a Windows in-place upgrade: This process allows you to repair your existing Windows installation without losing your personal files and applications. You can download the Windows 10 installation media from the Microsoft website, create a bootable USB drive, and then run the setup.exe file from within your current Windows installation. Choose the "Upgrade this PC now" option and follow the instructions to perform the in-place upgrade.

Did all 3, still have the same issue.

Can you send the minidump files for analysis: c:\windows\minidump

No such file exists.

Hi eahrend,

You can copy the DLL (of the same version) from another computer. To prevent permission issues, use Windows Recovery Environment's Command Prompt to overwrite the DLL. Or, use the takeown.exe command line I posted in this thread.
