=Read-Only=
For Steam users, to stop Fallout 4 from auto updating to the latest version:
* Find "appmanifest_377160.acf" and set it to Read-Only 
** I have two copies of the .acf, one each with the flag set differently

=Clean Base Installs=
Note: make sure you local saved games are safely backed up.  I'm not sure I'll look too hard in how to manage saved games (maybe there is a mod for that).
==1.10.163.0==
* '''Goal:''' Create a clean installation folder named "Fallout 4 - 1.10.163.0"
* '''Pre-Requisite:''' .....\Steam\steamapps\appmanifest_377160.acf is set to Read-Only 
** See notes above
* '''Background:''' Since the Nextgen update there have been mods coming out that require the pre-Nextgen Fallout installation to work.  Creating a clean base install folder that can be used as the foundation for starting different mod installs seems like the way to go. G

* Place the new folder at ...Steam\steamapps\common

==1.10.984.0==
* Make sure that the current Fallout 4 isn't really needed.  
* From the library manager, remove the installation.
* Start a fresh installation.  
* After install, before you run the game, copy the Fallout 4 folder
* Rename the copied folder "Fallout 4 - 1.10.984.0"
* Place the new folder at ...Steam\steamapps\common

==Clean Base Prep Completed==
You should now have a copy of each Fallout 4 base version, never run, at ...Steam\steamapps\common.  Next steps will make copies of these folders in relation to the specific mod.

=Vault 13 Demo=
* Go to ...Steam\steamapps\common
* Shift+Right click in the folder and select Open Powershell Window Here or Open Command Window here
** If the latter, type powershell.exe and press enter in the command window
* Run the following command and wait while it copies files
<pre>Copy-Item -Path "Fallout 4 - 1.10.163.0" -Destination "Fallout 4 - Vault 13 Demo" -Recurse</pre>
* Vault 13 Demo doesn't like cc (Creation Club) files.  Run the following command
<pre>Remove-Item -Path "Fallout 4 - Vault 13 Demo\cc*" -Recurse -WhatIf -Confirm</pre>
* Grab a copy of f4se for 1.10.163.0 and install that in ""Fallout 4 - Vault 13 Demo" per the mod installation directions of the mod.
