I just noticed all W.Z.T 16251 UUP files are going to be deleted by the hosts, DMCA. Weird that they request them so specifically, some builds are deleted and others left untouched It seems my 16251 Can Ref ESD's are not going to be taken down.
The issue has to do with nForce chipsets (both in notebooks - such as several HP Pavilions dating back to 7 - and desktops alike with similar chipsets - I used to have one of those as well). Worse, the GPUs of the nForce chipsets got kicked to the curb by nVidia prior to the first Creator's Update. It's why the oldest of my two Pavilions will retire from the Insider pool after rs3_release (it will be replaced with an ASUS X45C (K45) with the Sandy Bridge Core-i3). The particular nForce chipsets affected are nForce 7xxx/6xx (both Intel-CPU and AMD-CPU versions).
