How to make WMP actually open in 64 bit. (sort of)

Well I have wasted a day on this, so I might as well share it.

As you may be aware, 64 bit Windows 7 comes with both 32 and 64 bit Windows Media Player. However! for some reason, Microsoft, in their Infinite Wisdom, decided to make everything play in 32 bit only Media Player. You can change it around so that the shortcut on your Taskbar points to "Program Files" rather than "Program Files (X86)" but it will still open in 32 bit. Not only that, but you can't change Program Defaults to the 64 bit version! Effectively, the 64 bit version is just sitting there taking up space on your hard drive and not actually useful at all.

Now there used to be a simple Regfix for this with Vista, but Microsoft, again in their Infinite Wisdom have locked it out in Win 7.

Well after many hours of googling, and picking up little snippets here and there, I finally figured out how to do it.

So without further ado, here is how to make Windows 7 default to Media Player 64 bit:

1. Download "Windows Media Player Switch Script" from here: Unlock WMP x64 in Windows 7 x64 at Chris123NT's Blog

2. Extract the files to a folder of your choice and then run "set 64 bit ad default WMP" as Administrator (right click, run as Admin)

3. Reboot.

4. Now, (and this is the really fun part) Click Start>Default Programs. then click "Associate a File type or protocol with a program"

5. Go through every single Windows Media Player extension, and change it to "Windows Media Player" (Note: there will now be 2 Windows Media Player entries in the "Default Program" Window, with no way to tell the difference, the 2nd one (reading from left to right, and top to bottom, like a book) is 64 bit)

Unfortunately, there is no way to "batch change" them that I could see, you have to do every single extension by hand, singly.

I would actually not change them ALL unless you have a few hours to kill (there are alot) just change the ones for extensions you actually use.

Lastly: Unpin WMP from your taskbar, and open a music file or video, Pin the new Icon to the Taskbar, (the one that was pinned was 32 bit Media player, otherwise you end up with 2 Media Player Icons on your taskbar)

I hope it helps someone :)

2. Reboot

one question: is there any benefit to using 64bit wmp as opposed to its little brother?

That I can tell? Probably not. The only advantages that I can see, is that you don't need to download two sets of Codecs for Media Centre and Media Player if they are both 64 bit (which media centre is by default) as the X64 Codecs work on both.

Or if your like me, and just prefer to use 64 bit software on a 64 bit system

I suppose it might make a difference on HD videos or something, if they can run in a native 64 bit environment, but I cant confirm that.

The way to tell, is to launch Media Player and then open Task Manager (CTRL-SHIFT-ESC) under the processes tab, if it says "wmplayer.exe*32" then its 32 bit, if it just says "wmplayer.exe" then its 64 bit.

Just a thought, actually the first thing I did was this: Windows Media Player (WMP) - Vista Forums and then what I outlined.

The Script I posted, says it does the same thing though.... might be worth following the instructions there as well though.

I suspect thats because you did the right instructions first time I kind of screwed mine over, and tried to do the Vista regfix first, thats probably what broke it.

If someone else can confirm that the Script thing does actually do what its meant to, I will update the OP

By the way thank you for the rep, Normally I send a Visitor Message, but yours is disabled.

It took me a while to figure out how to do it correctly.
- there are many tutorials available Online but none were complete.

ie. inconsistent.. sometimes WMP x64 would launch.
ie. both x32 & x64 would show for "Open with...".
ie. both would still be listed under registered file-type applications, etc.

Here's how it should look.. only WMP x64!


Here's how to do it properly.
1. Execute following command in CMD Prompt:

Code:

unregmp2.exe /SwapTo:64

2. Open regedit & edit %ProgramFiles(x86)% to %ProgramFiles%:

Code:

HKLM\Software\Microsoft\Windows\CurrentVersion\App Paths\wmplayer.exe
HKLM\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\App Paths\wmplayer.exe
HKLM\Software\CLASSES\CLSID\{cdc32574-7521-4124-90c3-8d5605a34933}\LocalServer32
HKLM\Software\CLASSES\CLSID\{45597c98-80f6-4549-84ff-752cf55e2d29}\LocalServer32
HKLM\Software\CLASSES\CLSID\{ed1d0fdf-4414-470a-a56d-cfb68623fc58}\LocalServer32

normally.. most tutorials would end here..

3. Now search the registry using "wmplayer.exe" as keyword.
- verify found keys contain %ProgramFiles% and not %ProgramFiles(x86)%.
- there are atleast 20 keys that must be edited.
- and some require "taking ownership".

HOW TO TAKE OWNERSHIP OF REGISTRY KEY?
- Ensure you're running as Administrator.
- Right click key > select "Properties".
- Highlight "Administrators" > select all checkboxes under "Allow".
- Click "Advanced" > Owner tab > highlight "Administrators" > click Apply.
- Press OK until all windows are closed
- Now you can edit the key.

Look at how many keys i had to edit manually!
