Strange - but I half expect it to break in the next few days.) (After taking a system image i even tried the 2018-04 patch and it's still ok. In the end, after a refresh of Windows and a re-install of WMC it's ok again. HOWEVER yesterday's 2018-04 patch (KB4093112) broke something and today it was back to WMC freezing. Every Windows update has been installed without problem. After (me) wildly guessing, someone here suggested the fixes of disabling full-scren optimisation and over-riding high DPI - and it's been rock-solid for 6 months. I had the issue of WMC (version t-s 8.8.1) freezing when full-screen way back when 1709 came out. Click to expand.I am a little confused by the problems some have been seeing.
