Resources as in how? I remember dumbfucks complaining when Vista came out regarding memory usage, yet completely failing to comprehend pre-fetch at the time. This was still pre-SSD and traditional HD were slow as balls. Microsoft put in pre-fetch where your most commonly used programs would be pre-loaded into memory so they would be ready to run at lightning speed vs calling from the slow HD first. Of course people thought that empty memory was somehow superior from their WinXp days.
I compared it to buckets in a well. Your HD was the well, your data the water, the bucket your memory. What was quicker, pre-filling the bucket with water so it is ready when you want it, or having that bucket empty so you can crank it down to the well later?
Of course all of this is now a bit pointless with SSD mainstream.
Cloud service / telemetry? Umm.. just fucking turn it off like everyone else?
Bloat I can agree with. But there are ways to nix a lot of that too.
