How to remove ALL preinstalled apps in windows 8.1

I've been fishing through google trying to resolve the same issue.
(I don't exactly need the disk space; I just prefer to have a completely streamlined, personalized OS...and don't have time these days to learn all about Linux, lol)

Anyways, plaintuts is probably right. The OS is built to accommodate a trend towards cloud storage/management...so even if scheduled Windows Updates are disabled and you get rid of services like RDC that could contact their servers in the background, it may be futile.

That said, I think it's possible.
This is going to sound stupid, but I think the key lies in the method to deleting the system Desktop icons.

TrustedInstaller. This is the owner of many of the registry keys that MS doesn't want anyone to tamper with. Except, if you're an Admin you can give yourself full permission too and modify what you want.

The files you want deleted (camera.exe, filemanager.exe, and photosapp.exe) are guarded by the same owner.

Though I'm not sure yet how to do it, I think the apps removal relies on 2 things:
1) Elevating your permissions of those program folders
2) Removing write permissions from TrustedInstaller (otherwise Microsoft will undelete them)

that's my theory at least

Update:
I tested this with camera.exe by giving myself Full Control permission over the program folder (and all contained objects) and limiting permission for all other users to Read. Likewise, I deleted all program files, but left the folders themselves intact. My logic being that if the server sees the folder exists, it won't try and create a functional replacement.
I then rebooted.

Result:
The Camera app icon is still visible on the start screen, but clicking just opens an empty frame (no user interface or any other indication that an operation is performed)
...So all that remains now is determining how to get rid of that last little fragment.

Update:
Ditto with filemanager and photosapp, no adverse outcome.
