Also does it really work in Windows environments like it does on Linux, it seems like SaltStack and its brothers (Chef, Ansible, I forgot one) are tailored for Linux, and I dont want the master/server to be on Windows, that will be redundant I mean passing commands to Windows agents, and is their template library with commands where we can see what we can do under Windows.

So I can't answer for Salt since I don't use it, but I use Ansible for everything. For example, I have a separate DHCP and DNS server. Records are held in a YAML dictionary and when I need to add a machine, I add the DNS info and mac address and Ansible sets up the DHCP reservation on one machine and the DNS record in the other.
I also use it for kickstart configs. Instead of Foreman or Cobbler, Ansible has a Jinja2 kickstart template. When I run the playbook, Ansible creates all of the kickstart configs for all of the machines in the same dictionary as above and then creates PXE boot files based on the MAC address for each machine.
Ansible is pretty awesome with cloud services also. Dynamic inventories means you don't need to keep track of static inventories for your playbooks. Ansible can use any kind of script to get an inventory from AWS, DO, OpenStack, etc. As long as it returns JSON, your inventory is now the actual machines in your provider.

Not tailored for any specific OS. Windows works fine.

So this could also be useful for copying files to many servers at once from the central master I assume. For example, all minions need to have copies of source files that are updated from a central point. This could be used to push updates to all minions at once. Correct?
Yes. Or to tell them to all grab updates from somewhere.

Interesting thanks...

Generic answer:
basically Ansible, Salt, etc... are configuration managers. To understand when to use them, let say this:you want to deploy a machine (VM/physical, even a desktop)
a) you do it. so ok, next time you have to do the same task you have to remember what you did - and if the platform will change (run a web server on a different OS/distribution) you have to deal with the differences time per time.
b) as above, but you write all the steps (especially the tricky ones) on a file, so next time you have just to follow instructions and everything should be in place. Still OS is a matter but you can follow the quirks in your paperwrites.
c) you go over and you "drop" the minutes in favour of a script (shell/powershell etc...) which - if well laid out, will automagically re-deploy the machine again and again and again with a lot of custom if/else logic...or...
d) as above, but you do it with a CM script.
It is all about how much reproducibility, automation and platform independence(°) and standardization is a requisite for your job.
(°) you have to deal with platform at writing time, not at run time. Also idempotency is not always attained with windows PS things.Personal example:
Recently, I've migrated my VMs from KVM to hyper-v, rather than do anything else, I've used the existent VMs as a target and I've tried to reach the same objective by using fresh installs on hyper-v and Ansible scripts for deployments. My playbooks (ansible code) are still rude but I push them on bitbucket with git and I will be sure that next time I'll need a VM (even for testing) I will be able to fire a script and get exactly the same env. -

@scottalanmiller Why not just rsync directly to the master? You want versioning?

Yes, and multiple users, and a central repository.
