This is for Xbox's that are running Xbox Media Center or XBMC for short, This is a Modded dashboard that you can get from various sites including XMBC site, This will only work in XBMC (this guide anyways...)
Now befor we get started! we need to go over the things you need!,
1. Modded Xbox (softmodded or chipped)
2. XBMC installed on your Xbox
3. Windows PC
4. Router (doesnt matter which kind!)
5. Ethernet cables of coarse!
Now we need to boot up both Windows PC and the Xbox. Once you get the Windows PC all you need to do is find a location for your folder you want the Xbox to Connect too. I will be using the Root of my C:\ Drive with a Folder named "Xbox1", Once you create your Folder you must Right click on it and select "Properties" now a window will appear quide your self to the "Sharing" tab located at the top, Now You will see a box named "Network sharing and Security" you want to check the option "Share this folder on the network" it will give you the name of the folder "Xbox1" or what ever you had named your folder, Now there is another option, it is optional "Allow network users to change my files" since the xbox cannot change the files/delete/rename you can have this on or off. Now click "OK" to save these changes

Now thats it for the PC side of things all you want to do now as turn on your Xbox and make sure you have a Ethernet cable from the Xbox to the router that is connected to your Windows PC. Does not need to be connected to the internet, as long as the Xbox and PC are connected via Router or straight to each other
Once booted up into Xbox Media center which will look like this,

then locate your self to the MEDIA tab, by clicking Left or right on your D-PAD or Analog,
which will look like this,

Now go to Photo, or Music/video (im using Photo as an example)
which will look like this,

Now click on "+add source" this will be an extrenal source to your PC's HDD,
which will look like this,

Once you click on add source a window will appear on the side,
which will look like this,

All you have to do is click on Browse at the top make sure it says Windows Network (SMB),
which will look like this,

Now Browse to MSHOME (depending on your network configuration MSHOME is default for Windows, but if you changed it, it will still show it) and select it!
Which will look like this,

Now there will be 2 folders, only because if you made your Own folder named "XBOX1" or similar it will appear,
which will look like this,

Now once you select it, click okay!
which will look like this,

You will go back automatically to the directory of your partitions on the Xbox, go down and select the one you made which will look like this, and hit OKAY,

Now you will see an option like this,

This is the network source linked to your PC accessing the Shared Folder you made!
You can do this for all media on XBMC, even apps if you use File Explorer,
Video/Music/Photo/Games/Roms/apps
All you need to do is go to your Windows PC and make sure you have created thoes directories/folders in the XBOX1 folder or which ever you named it.
Once your done, all you need to do is drag and drop the media on your computer into that folder,
In Xbox go to the source you created and browse which media file you would like to play!
NOTE: THIS IS NOT A XBOX360 THIS IS A NORMAL XBOX, XBMC IS THEMED TO LOOK LIKE A 360, SORRY FOR THE CONFUSION IF THERE IS ANY!
SIDENOTE: This is by far the easiest way to do this, I will not post on how to enable a 2nd account on your PC, doing so will slow down the performance of your pc (more files and another pointless user not needed) and this is alot easier to do. This for thoes who would like a Media Box in there living room! you can even stream radio to your XBOX! i will post more guides and helpfull tip's that will show you the Best performace out of your Xbox running XBMC, Thanks (and yes! there will be milk and cookies, and pictures too! of coarse!
If you have ANY! quesions at all! please feel free to PM me about anything!!
Thanks,
