it worked!
i created this account primarily to extend a huge thank you to you willsy! i have two laptops and upgraded from win 8.1 to 10 on only one of them so i could see how things went. everything seemed fine at first. when i installed 10 on the second machine that's when everything went haywire. since i lost internet connectivity on both machines i thought it was the cable company. (i have been on this for six nights and a good portion of days too). i replaced the cable company's modem/router with better equipment but no luck. i bypassed the router, but no luck with ethernet either.
i reverted back to 8.1 on one of my machines and had wifi and woila, i had wifi & ethernet connectivity once again. my victory was short lived though because apparently the trusted security certificates were wiped from my machine. i couldn't even download them from the microsoft site because the site took me to was https and that rejected. in a last weary act of desperation i did a complete reinstall of win 8 wiping out all of my programs & configurations) and upgraded to 8.1 from there i upgraded to 10 again and everything worked--full connectivity.
i spent the entire night reloading programs and configuring settings getting ready to wipe my second machine when, for no apparent reason, i lost all connectivity again while downloading a program. in a last ditch effort before completely wiping both machines and starting all over with 8.1 as my final destination i read your post and it worked! of all of the hundreds of posts i have read during this last week's journey your is the only one that worked. i wanted you to know that you quite literally saved the day! thank you for taking the time to post your solution.
