How do I stop random programmes from using resources on my PC?

[Snaked_Snake]

I'm sick and tired of starting up my PC to see something like Microsoft office using like 20% cpu and 10 MB/s from my disk

I've tried closing them on Task Manager but they just pop back up using the same amount.

Get CCleaner and take a look at the programs that are allowed to start when windows boots or will do background processes. also clearing up cache might help and use a different browser than Chrome if you care about your memory
