Happened 2 days apart- BSOD at login after briefly showing desktop.
I had tried many times to upgrade to W10 if that matters (but restored using image file)

Hi bam12,

Please try a repair install of Bitdefender and let me know how it goes :)

Thanks Axe0
I couldnt find how to repair install it but i will d/l a clean uninstaller then get a new copy installed.
Are you aware of the hotfix mentioned here (https://support.microsoft.com/en-us/kb/2664888)? I dare not try it without checking first.

You can repair Bitdefender in the programs & feature list in control panel :)

I'm not aware of many updates of Windows, this update seems to be a fix for a freeze issue. Worth applying if you ask me :)

Thanks again - I did not see you could repair there. I did both so now will mark as solved. We shall see.
