How do I do this.
Thanks for all the other recommendations
In the control panel under administrative tools is the services manager. Have a read through each one and disable anything that looks suspicious... also run msconfig from cmd and kill the ones you dont need there too. Also remove things like Onedrive from your startup processes if you dont use them
WARNING: Killing stuff from the shell is more or less irreversible. If you like the calculator, Windows Store or Cortana then dont do this.
This will remove *all* app packages from your windows. Things like the weather app and those stupid flash-esque games that come with a fresh install tend to bog your resources especially on slower machines.
Please note that some things like the windows calculator, windows microphone recorder and windows webcam recorder are classified as apps and will be removed. You will need to install other software like Microsoft Mathematics, Audacity and OBS to be able to do those sorts of things.
Windows store will be permanently removed. Anything you may have bought through the store will not work.
When I say this will revert the machine to a bare bones state in terms of programs, I mean it.
To do so, let the machine go through normal windows update and click on one of the bloatware games in the start menu to have them all download and refresh so you can kill everything in one go.
Next type "power shell" into your start menu, right click and run as admin. Then insert these commands one at a time (copy paste from here if you can. The commands are case and punctuation sensitive). Dont worry if some of the services scream as they die as it is normal (that is you will probably see some errors show up so dont worry)
Code:
Get-AppXProvisionedPackage -online | Remove-AppxProvisionedPackage -online
Get-AppxPackage -AllUsers | Remove-AppxPackage
Then restart your machine and bask in the bliss of a bloat free windows 10 install
