Windows 10 is great but comes with a lot of useless things and can get really bogged down with the telemetry thing. These tips and scripts will help lighten it up a bit.
There are a couple of scripts that can be run to turn off some things, but in order to run them you need to open PowerShell as Administrator and type/paste this code: set-executionpolicy remotesigned
^^^ You actually shouldn't need to do this anymore, you can just run the reclaimWindows10.ps1 script from file explorer. This script is from https://github.com/Disassembler0/Win10-Initial-Setup-Script and is awesome, the only difference between that one and reclaimWindows10.ps1 are the defaults enabled.
