How Can I Maximize Internet Speed?

That other issue is separate and already being addressed. You cannot remove embedded programs that are required by the OS to stay active. There is nothing that you can do about those items staying, nor do they report private info, just collect data points and sends to Microsoft, so that they can tell when a problem happens if it is their OS or third party software.

@xlook please provide a speed test.net result as requested above. We can't know if you're getting the speed you're expecting until then. Also what speed did the ISP say you'd get?

This is mine from a moment ago:

You have resisted following our requests to place the information into a post. If you are wanting to continue putting up a block wall by not disclosing the information, you requests for help will end up getting buried into the land of the forgotten.

Simple questions, simple answers. You have filled out your system spec's, but have not posted your IPv4 Ping times, along with a copy of your speed test in a post. Having it in your Spec's, does not show up in Tapatalk.

Setting your comments above aside my *unverified understanding is that windows can reserve as much as 20% of your available ISP bandwidth at any given time or constantly for it's own use or whatever .

I have some multiple registry settings and CMD strings in a routine from a credible PC website that are *alleged to eliminate that windows bandwidth overheard ( * if it exists. ) but IIRC they don't claim to have validated all that either .

I've tested all that with inconclusive results that could just as well be naturally occurring variances and I'm not about to give it up to someone that may not have the requisite technical skills to change those parameters without hosing thier OS anyway .

FWIW 1080p Netflix is at best 5800 kbs ,Netlix ,You tube and other 4K IPTV maybe 15 -25 Mbps so if you are up in the 50's and not transferring huge files via ftp or something you should be fine anyway and some of that IPTV is data burst's anyway .

My 4K Sony TV is rock solid reliable at most 4K IPTV or any 1080p on a 25 Mbps ATT FTTN Broadband service profile with other family in the house on line or instead with all total 3 1080p IPTV videos on ,a PC and no 4K .

All that is sometimes over provisioned by ~5 mbps or not at all .

ofc I'm close to the VRAD ,not a lot of copper POTS line in between me and the VRAD , and the WI FI router / RGW is on a home run to the NIB. .
