What exactly did you try in another thread?
Pinstripe posted this fix, which has worked wonders for many:
Leave the multimedia class scheduler service running, but disable its network throttling "feature":
- Open regedit
- Go to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Multimedia\SystemProfile
- There will be an entry for network performance throttling, default value is 10; set it to FFFFFFFF hex (willl look like 0xFFFFFFFF to the right of the entry)
