Hi guys, interesting find regarding the problem I encountered with WDSC on Microsoft forum.
Having problem with Windows Defender Security Center - Microsoft Community

Ah @Jhawk55, so it's the High Contrast bug! Yes, I investigated that one back on 24th Oct. The bug then prevented Defender Security Centre from opening at all.

I found on testing that the High Contrast Black and High Contrast White themes worked, #1 and #2 didn't. As this appear to be a bug, it may get fixed in a cumulative update and you could switch back to your preferred theme.

windows defender security center dosn't start correctly

Since then we've had several cumulative updates and an update to the Defender Anitimalware Client. This has at least let Defender now open, with the side-effect that my testing now shows that the only high contrast theme that it works fully with is 'High Contrast White'. It's an improvement (of sorts) I suppose

Until they fix this properly, the only workaround is to switch to 'High Contrast White' or 'None' to use the affected parts of Defender, then switch back to your preferred theme once you are done.

@caledon, I have not tested yet since I am at work, will test out when I get back home.

@Bree, thanks for sharing with us your findings.

Updates, I confirmed that WDSC works fine in High Contrast Black mode. I also found that any color I changed to the High Contrast Black will breaks the WDSC again, unbelievable... Looks like I am stuck with using the default High Contrast Black mode for time being. Bye...

Updates: Just upgraded my Windows 10 Pro using the "Upgrade Assistant" to version 1803 (Build 17134.1). Found that they have finally solved this issue between using "High contrast theme" and "Windows security center".

Wow i'm waiting with bated breath to get the update for (home 64) in Guam still.
