I seem to have trouble finding ADM & ADMX Template downloads when I need them.

Maybe it's the keywords/tags - maybe it's the different product groups, thinking about them in different ways.

Anyway, here's a selected collection of the ones I go looking for, maybe you do too.

NB: as of 2015/2016, I've noticed that recently released Security Updates or Cumulative Updates, for Windows and/or Internet Explorer, are shipping updated ADMX/ADML files e.g. inetres.admx/adml for IE. So, if you can't find the setting you're looking for in the downloads section, you might need to grab the latest CU for Windows or IE to get the freshest ADMX/ADML. This concept also seems to apply to Win10 upgrades (e.g. 1507 -> 1511 -> 1607)...
