I'm setting up a new laptop running Windows 8.1. I keep finding the Windows Media Network Sharing Service keeps starting up when the PC is otherwise idle and running at 90% + CPU load for long periods. There is no demand for media streaming when the process is running.
What is this process for? Can I disable it or reconfigure it to reduce the CPU load?
So I've been having this problem for days now, two tasks named Service Host: Local Service(Network Restricted) and Service Host: Local Service(No Network) keep using up ALL of my cpu, theyre usually accompanied by any app I have open, so my task manager is basically like this for example:
Service Host: Local Service(Network Restricted) 40% cpu usage
Skype 29% cpu usage
Service Host: Local Service(No Network) 26% cpu usage
If I close skype, the usage goes down to 2 percent for a brief second and then any other app I have open launches up instead of skype and uses up all of my cpu.
I've tried several virus scans and I've done my best to clean up the system but I still have this problem
Recently I have noticed an unusually High CPU usage from 'Service Host: Local System (Network Restricted)(11)'
I have tried the fix from this thread, but it only works for a few minutes.
As soon as I start an application (Cadence Allegro PCB Designer 16.5 but I don't think it's relevant) my CPU usage gets to the roof and stays there long after I killed the application and I believe I every associated process. The CPU usage is so high that the battery will be drained after about 45 minutes (It usually last about 3 hours).
According to my task manager the responsible is "Service Host: Local System (Network Restricted)". As a matter of fact, preventing the executable from accessing the network sort of solves the issue. I don't believe I need that executable to access the network but I'd like to understand what kind of network service can consume that much CPU (was actually affraid of overheating) and to know if there's a more appropriate way to solve this.
Windows 8, after 4 minutes of idle my notebook i get high cpu usage , i tried understand why occurs this problem with KernRate and get such trace log.

Why occurs high cpu usage?
I just bought a brand new Lenovo U310 Touch and so far I absolutely love it. The only thing I noticed that struck me as odd is that when I look in Task Manager it shows that I am using around 60% of my available memory, but there are no processes taking up anywhere near that much. I also have a desktop I built and its memory usage is nominal when idle so I know this isn't a "standard feature" or anything.
EDIT (5/4/13) - Finally figured it out, it was the ExpressCache program, used a couple tutorials to isolate where the memory leak was and from there I found it was in the running files of ExpressCache, I just went to Uninstall Programs, hit "Repair" on the program and now everything is all nice and happy, no more memory leak.
I've noticed that when I leave my pc for some time and the screen savers come on, then the screens go blank (my machine doesn't sleep or hibernate) when I use the pc again I can see that during the time the monitors had turned off, the CPU usage was at or above 50% ? When I use the computer after that, watching movies, photoshop etc the cpu usage is much less than that!

View 2 Replies View RelatedIt seems as if my computer is using way too much RAM for some reason. I currently have 6GB of RAM installed. As soon as I start my computer up, I'm greeted with this warning:
So I decided to open up task manager and see exactly how much RAM I'm really using:
No process is using up any amount of RAM to come close the above number. The most RAM using is 70mb or so from Google Chrome while typing this post. Clicking on the performance tab of task manager gives me this information:
I haven't downloaded anything recently. I had this exact problem a few weeks ago and a system restore fixed it but I'm not wanting to wait on the computer to restore again or for this problem to just come back again. I'm running Windows 8 on a Toshiba Satellite L875D-S7332.
So for some background I basically stream music, pictures and video content from my computer to an Xbox 360 in the lounge room for my family to enjoy. This has worked for quite a long time with Windows 7.
I installed Windows 8 Consumer Preview today and got settled in with it and indexed my libraries with Windows Media player so this could resume. But to my dismay this doesn't seem to work in Windows 8.
I have each folder and hard drive shared on windows for network use, I have a little experience from LANs in this area. I have enabled all streaming options in WMP that I know of and the entirety of my library has been fully indexed. This is WMP 12 and everything I possibly know of is up to date.
I haven't got the Homegroup feature active as I never had to use this before.
The only other thing I have noticed that has changed is this. A little green icon that in windows 7 would appear on top of the xboxs, I'm assuming this means something.
On the Xbox end it used to display the Libraries such as 'Recorded TV', 'Music', 'TV Shows', 'Movies' and other things but now when I try to access video content it gives me a folder called 'Videos' which contains nothing.
I am having problems with my memory it has jumped to 89% and stays there. I tried to restart i looked at the processes it seems that non-paged tools is taking the most. I used RamMAP tool to find this problem.
View 5 Replies View RelatedOver the past couple of weeks I have been getting high disk usage on my computer, causing it to run extremely slowly.
Just after I took the attached screenshot, my System went down to around 6MB/s and the "Service Host: Local System (Network Restricted)" jumped to around 16MB/s Looking in resource monitor the main things causing the high read speed are:
'rundll32.exe' and 'ccsvchst.exe' and one just called 'System'
I recently installed Windows 8.1 on my Inspiron 7520 and I noticed that during the startup the disk usage is around 98/99% of my Samsung SSD 840 Pro 120gb.
I saw a lot of posts where the users complain that, during this high usage of the disk, apps don't open, the system freezes around 5 minutes and after that, there are random high usages, even on idle. But in my case this high usage lasts only few seconds (around 30s), I can open some apps with no problems and never happens again on idle, only if I restart Explorer.exe. If I restart it, it happens all again.
My question is : Is it normal? The high usage only on startup? My only worry is mess up with my SSD due this usage.
On Performance Monitor, the process which writes a lot is System. I disabled every 3rd party app on startup.
I have a new laptop windows 8.1 (64bit) 8gb RAM i7 processor which should be sufficient for the software I use. However on start-up my memory is already at around 80% and stays like that.
The most seems to be caused by servicehost (network restricted) (11) another program is IAStorDataSvc (32bits) even after i updated Intel Rapid Storage it still seems to take some memory. (My system settings are in Dutch but I guess it's pretty much the same as in English).
What could be the cause of the massive memory use?
How to reduce Local Service (no impersonation ) CPU usage..?

Windows 8 Genuine 64 bit

Now the problem is there is one service Service Host: Local Network Restricted it consumes 100% disk usage and computer starts acting. I have to manually kill this process from task manager around 4-5 times to end it.
I have recently discovered that my laptop cooler was going crazy and I didn't knew why, then I started Task Manager and there it was "Windows host process (Rundll32) eating 30% of the cpu.
Notebook specs:
Cpu: Intel Core i5 3210m
Ram: 8gb ddr3 1600mhz
OS: Windows 8.1 x64 pro with the latest update
I'm using the same programs as my old system which also had the same amount of ram (2x4GB 1600MHZ) and the usage was very low.
This PC was only built 4 days ago the current ram is 8GB (2x4GB) Corsair Vengeance Pro, 2133MHz, CAS 11-11-11-30, 1.5V
The first two days that the PC was built I noticed the idle usage at 88% and if i ran a program it would hit 100% and pretty much freeze the PC so it's not an error in the display.
Mobo is MSI Z87-GD65 and I'm running Windows 8.1 with no updates.
Probably not anything to do with it, but i'm running beta amd video drivers and it's showing my card as 5GB, I'm planning to uninstall beta drivers and run updates. Just wanted to know of others opinions.
I bought this Vaio with Core i5-3210M, 4Gb Ram, Windows 8 64 bit. I had really high hopes for it, coming from an i3. For the first few weeks it worked fine, but then it started to freeze while watching movies. Then it started happening all the time, and the cooling fan became consistently noisy for working at full capacity.
I was used to opening task manager on older systems when this happened to see if there was a non-responding program and force it closed, so I noticed Task Manager offers some more features in Win 8. Here, I see that CPU usage is high, staying always around 70% and from time to time reaching 100. At this moment, the process taking the biggest slice is called VCS System Tray with 58%.
What's perhaps more concerning, is that Disk usage is almost constantly on 100%. And by this I mean it reaches 100 and stays there for long periods of time, perhaps up to 20 minutes, then it falls down a few seconds and up again to 100. During this time the computer is excruciatingly painful to use. To even open a program takes forever. When this happens, it seems that Chrome is at the top of the list of processes with most disk usage, with about 1-2Mbps, but this sometimes changes and the list can be led by System, Utorrent, Octoshape, VCS System Tray, Communications Service...I think it's not related to any process by itself, but its nearly ALWAYS at 100%.
Finally, memory usage is also pretty high at 78%, but I guess this may be because 4Gb is not too much for this computer. I'm hoping to upgrade to 8 soon. Out of the 10 processes consuming most memory, 9 is Google Chrome (how's that even possible?).
My task manager is showing an unusually high CPU usage by the system, anywhere between 20-30% when the computer is idling. I've run the sfc /scannow utility and it found some corruptions, which were then fixed by the DISM utility. However the task manager is still showing that super high CPU usage and no amount of restarts is changing anything. I've attached an image of my task manager.
View 9 Replies View RelatedI have high usage on my laptop lenovo g580 using windows 8. check task manager and I see cpu memory and disk fluctuating up and down to 3% can go up to 100 at times. When I open google chrome. Watch video or play games. I hear my fan turn on and i think my hard drive and i check task manager and i see the problem happening. I did a virus scan and searched everywhere online. I couldn't seem to find a solution. When I am not using the pc its a stable 3 percent but my memory is at 37 which i barely have anything installed but 1 game and a google chrome.
View 1 Replies View RelatedI bought new lenovo ideapad Z400 touch 2 month ago with Windows 8. Last week i upgraded to win 8.1 and recover back to win 8 , since then i have some problems.
When I have the Task Manager open, I notice the disk usage climbing to 50, 75, 100 also the CPU , even though there's scarcely any disk activity going on, the laptop's fan is working harder and very noisy , my processor's speed and heat are jumping high without any programs on.
I tried almost anything, checked for viruses, disabled unnecessary startup programs, clean boot, but it still the same.
Today I upgraded from Windows 7 to Windows 8.1. For some reason, after upgrading, my hard disk usage is always hovering at around 60% usage and my CPU usage is always hovering at around 50%. This is when the PC is idle. When I was using 7, the disk would rarely jump over 30% usage and the CPU would never go above 7% when idle. The sound of the hard disk constantly working away is doing my head in, not to mention it's at around 50 degrees as opposed to 45 degrees previously.
View 9 Replies View RelatedIn window 7 it uses maximum 2gb of ram when transfering big file, say an example a movie size of 8gb. now in windows 8 it seems it uses 6-8GB its as if file is transfered into ram first and then slowly copy into targeted disk. just what is going on here and why microsoft decided to do this? if power goes out then all the files is gone and the entire process is actually slower imho.
Is there anyway to disable this? or revert it back to similar what 7 had?
Basically when I start my laptop everything is good for a while when suddenly the CPU usage goes high because of System Interrupts (~25%) and System (~12%). I have tried using LatencyMon to track down the problem and it used to give me alerting messages but now it gives me messages that are all green and nice ("Your system appears to be handling(...)").
NOTE: My drivers ARE up-to-date, but I am not sure my BIOS is. I don't really know how to update the BIOS though, it's a really weird model I have here, that has become obsolete.
*update1* Upon thinking that it might be the wireless driver or the network driver I disabled both, but it didn't drop the CPU usage
*update2*Now I get disconnected from the internet randomly... it may be the wi-fi driver after all

high ram usage problem - Imgur
So why is that?
So I booted up my pc this afternoon, but notice with my monitoring software, my cpu activity was going nuts.
I opened task manager, and sorted by cpu usage, and " Store Broker" was using app 35% of my cpu just sitting at desktop. I ended it in task manager - what the heck is this and why would it be running?
My cpu usage reaches 30% whenever i watch a youtube video. why is this happening? should it be using 5-10% at the most?
