Thank you guys, it looks all OK now. When I checked this morning everything seems fine, it must have been a minor glitch. Thanks again for the help.

wmpnetwk cpu issue

I have same sort of problem, but i can see what is causing the problem - wmpnetwk.exe - i assume that is windows media player networking for streaming? I usually network with my other pc's through my server? If i turn it off it starts back again. I guess i can turn services for it off, but will it make my network drives unavailable?
Thanks for help.
I'm an XP guy can ya tell - lol

Yes it is, and no it will not disable your network - it is *strictly* for sharing and searching for shared media, that's all.

Thanks Johngalt - that was it :D - just wanted to confirm - as i found here for the benefit of others to see and understand it

What are wmpnscfg.exe and wmpnetwk.exe and Why Are They Running? :: the How-To Geek
Click to expand...

I have this problem, but I want to still run media sharing to my 360.

Are there any known actual fixes for this problem?

I could run media sharing with my 360 fine on my Vista install, but now on Windows 7 I just get CPU maxing out all the time. :(

Have you installed any codecs? I heard around here on the fourm that the service in question gets stuck on certain files and thrown into a loop. Which sounds like a problem with a codec.

Nope, I was having the problem before I installed anything. I had it before and figured it could have been an install issue, so reinstalled W7, run Windows Update etc. only, didn't install anything else, ran WMP12, then after telling it where to find my media it started throwing a fit.

Could it be due to video files that WMP12 needs codecs for, so it gets stuck? I don't normally use WMP for watching videos, I use another player, but have to import it into there to be able to use it on the 360 should I wish to do that.

Might just be the initial startup phase, lots of indexing to do and other activities. If you have a lot of media and told it to index it then yeah thats going to hammer away on your CPU until its done.

Did WMP ever stop hammering your CPU?
I ended up stopping the service but now think of using Media Center and will have to start the WMP service again.
Was curious if the was a fix?

I installed (clean install) my Win7 a week or so after it first came out (via advanced purchace). Ran fine until a week or two ago, then I started having problems with it maxing out the CPU. I could "fix" it temporarily by rebooting, but sometimes it would take an hour to shut down, and sometime I just had to use the reset button!

Some investigation lead me to disable the wmpnetwk service and, so far, it has seemed fine. I hope it will stay fine.

Meanwhile, I need to ask if an update effecting wmpnetwk came out recently? Like I say, the system was fine until recently. I am fine without wmpnetwk.exe running as I don't do any media sharing, and don't even use wmp, but I would like to know why things changed.

Any thoughts?

My CPU sometimes runs at 100%, but I'm pretty sure it's just throttling. Some modern processors slow down their clock speed or shut off some cores when not in much use.
