You guys are right it can be very hard to reproduce an issue that has happened on very few PC's and therefore cannot be reproduced easily.
My main desktop originally had the issue but then I reinstalled and it seemed to work fine, so I thought as it was without the iType.exe software I would install it again to see if it would reproduce again. I downloaded the Intellitype Pro software seeming as that was what was causing the issue (iType.exe) which is packaged inside Windows Mouse and Keyboard Center, but still no issues here allowing me to use my multimedia functionalities. Although while using my tablet (Surface Pro 4) I still have the issue and it is completely related to the iType.exe or Intellitype Pro software (ending iType.exe fixes the problem) so it is somewhere within the Intellitype program which I cant seem to reproduce on my main desktop for some strange reason. The issue seems to be happening no matter what keyboard you use which uses multimedia keys so therefore must be software related.
For those who have the time (as it is becoming a stressful part of the year), they can either download these programs and see if they are reproducible and then test it themselves. This problem is most likely up to the community to fix.
Here is some software downloads that you can try:

https://www.microsoft.com/en-nz/download/details.aspx?id=26950 (The Software Itself)
Also I read around that there is some sort of patch for musicbee if I am correct? 3.1 I believe, I would be interested to try that patch is there a download link to this, because musicbee does not auto update to it?
Anyways I am completely unsure if this is helpful to any of you, but I hope that I have provided a better insight for you guys to test yourselves and see if you can reproduce the issue when you have time. I can understand it is coming up to Christmas and I will give you guys some time which you clearly deserve, especially you moderators and admins who devote their time to these forums.
