This is not a third party issue per say. These are windows background programs that cause high latency.
There is nothing you can do but return the computer/parts and try something different. I have never heard of someone solving this issue.
Apparently not everyone has this issue, though i wouldn't know. My last two laptops is a row had it. Not even the same brand. My only guess that Windows will not work with certain hardware. It doesn't make a lot of sense and microsoft doesn't give af if it only affects a few thousand people.
Its a shame such a trash company is still your best option.
