For some reason I can not for the life of me get Preview Builds pushed to my rig. I enabled Fast Ring over a week ago. Yet, every day I check for an update I get nothing or just your normal defender definition update.. I tried the Update Reset tool, deleting everything in SoftWareDistribution.. Nodda.. Checking for updates takes so long now also. I remember it used to only take a few seconds or so to check for updates.. Now it averages 1-5 minutes to do a full check.. Any insight on something else I should try?
