When I start WMP the window opens immediately but it takes nearly 12 minutes to complete the startup. During most of that time the CPU usage is at 0%. Every other application starts up almost instantly and WMP runs fine once it has finally started up.
The program itself is stored on a SSD drive whilst the music files are on a conventional hard disk and they total 871mb. My system is a quad core i5 processor with 8gb RAM running Windows 7, 64 bit.
