Hi Celestra & brasco
Have to say that I tend to stick with Windows Media Player as Kemical says it works best with the OS. I found several years that others such as Real Player caused conflicts with my OS at that time to the extent that it became intrusive.
Perhaps in time 3rd party media players might perform better than WMP11 but again its down to personal choice.
Meantime I found this solution on a "google"
1. Close RealPlayer.
2. Make sure that UAC is turned on.
3. Right-click the icon or shortcut which you use to open the program, and select Properties.
4. Click the Compatibility tab.
5. Click the Show Settings For All Users box.
6. Click "Continue" or "Allow" on the prompt that appears.
7. On the new window, check the box...
