I seem to be finding a problem with build 7600.16385.090713-1255_x86 on my Acer laptop that i have never had before with any build.
it seems to be with Windows Media Player network sharing service.
all parts of this service seems to be using almost 100% of system resources.
The only way I can solve this problem is to disable the process. Trouble is Media player will not run without crashing. i have insalled the build twice but still getting the same problem.
I am sure I can't be the only one getting this problem.
Update: the problem seems to be caused by wmpnetwk.exe, it seems to constanly be running at 50% processor usage. If I stop network sharing service then all is fine.
