Windows 7: Windows started compressing wav files with IMA ADPCM instead of....

Windows started compressing wav files with IMA ADPCM instead of....

So we have some software the saves audio to wav file format on a windows 7 Pro box.
For years this has been running great and windows has been converting the audio and outputting a wav file with Microsoft PCM format.
Recently something changed.
THe wave files are now IMA ADPCM compression format and it is causing us a lot of trouble.
I have tried to find a way to go back to just PCM but I can't figure it out.

Anyone have any good ideas?

I just want my wav files to always be in Microsoft PCM format.
The software vendor says that this is not their problem and has to do with the codecs on the windows system itself.

Thanks

Sounds like something you installed (intentionally or unintentionally) has set the IMA ADPCM as the default format. This could be some media player.

It probably is not the program you have, but whatever program has changed the file type.

I did some google searches but couldn't come up with how to restore wav as default format.

(I have a recording studio so I do a lot of audio work).

Thanks for your input fireberd.

More details:

This system runs like a "server"
There is one main piece of software running on it and nothing additionally gets installed or uninstalled.
There is no user for this system.
It sits in a network closet and I am the only administrator that may connect to make slight changes from time to time.
So when it comes to software that has been installed, I have to say there has been nothing, just regular windows updates.
Now granted maybe something was installed in the background or unintentionally but I can't understand what.

Not sure when this problem started, I almost feel like it started out of the blue.

The only software installed recently was:
- Microsoft Silverlight update to version 5.1.4.0.4.16.0
- Microsoft Visual C++ 2008 Redist x64 version 9.0.30729.6161
- Microsoft Security Essentials 4.8.204.0

I just heard back from the software vendor.
Even though they swore that this issue was not on their end and that it had to do with windows now they are saying that the change may have been done by them....

Sorry for bothering everyone.
I guess this wasn't a windows 7 issue afterall.

Usually its not the OS.

I was a LAN/WAN Network Manager and dealing with vendors is a real headache. The first response is usually "its not my problem".

Compressing wav files
In XP, Sound Recorder was very useful for compressing wav files. However, in Windows 7, Sound Recorder does not do that at all. Can the XP version of Sound Recorder be installed in Windows 7 or is there an equivalent alternative ? I can't find anything that will do that job. Robert.
