    I have just done an upgrade install of CU and could not even find Defender. Cortana couldn't locate it and it was absent from the 'All Apps' list (Shawns second picture above). Everything else was there, just no Defender.

    On a hunch I tried a restart and lo and behold, it has now appeared.

    Ha ha ha

    If you've any ideas on my other issue posted over in 'Browsers' then I'm all ears I'm actually wondering if something could be configurable in Defender that might be at the root cause of this latest problem. Someones just posted, I'm off to have a look......

    Hope your installs/upgrades went OK anyway Cliff.

    Edit... browser issue mended now

    I noticed tonight that windows defender or the windows defender security center both are not in my all apps list. When I start ms services it shows that defender is running. I just can't seem to open the security center. When I try to via the settings window, nothing at all happens. No error message, nothing. I rebooted and still nothing.

    My calculator and photo viewer also quit opening but right now I'm more concerned about windows defender since I don't have an alternate av on my system.

    If you have a serious number of Apps and windows features not working then it implies there is some underlying corruption of your system files. The quickest way to sort this out is to follow this tutorial. Following it exactly will ensure you keep all your documents and settings. It effectively reinstalls your current version of windows and keeps everything you had previously installed as if you were doing an upgrade.
