Security :: WMI Provider Host Hogging 20% Of CPU
Aug 3, 2014
Lately, I have been experiencing a slowdown on my computer. As any other person would do, I opened Task Manager and saw that a process called WMI Provider Host took 20-30%, of CPU. I tried to end the task but it continued to open up. I went into my anti-virus software and found nothing wrong. I looked into my Event Manager and got back to a .dll opening the script making WMI Provider Host open. the .dll is called cimwin.dll. That opens it and other Activity Transfers open it.

I have run into some networking problems and I think I have narrowed it down to the homegroup provider.
I have 4 windows 8 pro x64 computers connected to a router. Up until now, I have been able to disable the homegroup provider service because I don't want to use the homegroup and don't want to see it in my file explorer. I have been able to connect to all the shared computer drives up until I tried to disable the homegroup provider on my netbook. When I did this I lost the ability to connect to other shared computers. I re-enabled the provider, however I still cannot see drives on other computers. I can now see my netbook on the other shared computers.

I'm at the point of no return with Hyper V. I have finally gotten access to the Internet. For the next step, where I can find Step-by-Step instructions to gain access to a Host Hard Drive from the VM. I have the MS Windows 8 Inside Out and it is of no luck. For some reason accessing a Hard Drive wasn't important.

I have done installation of windows xp sp3 on a guest virtual machine and i have problem with networking. On my host machine (windows 8.1 ) i have 1 static ip and i can't have anotherone. So from this ip i have to share network to guest machine. The guest machine tries to get ip from dhcp but it can't. When i give it manual ip address (the ip from host computer) it works ok but i have to turn off host's network card because they cant have tha same ip address.

Since I installed 8.1, my machine is running hot, 45c, but when I shut down one of the many Service Host:Local Service(s), it drops back down to 20c, where it was always with 8.
I can manually shut it down each time.... but I's like to block it from starting in the first place. Shutting down seems to have no other effect other than dropping the temp.
I need to find a fix.... or go back to 8.

As I am having problems with USB and getting my workfiles onto my guest machine I thought I could load them onto my host then access them via file sharing. I have set up the VMware player with the location of a shared directory on the host but I cannot see that on my guest XP desktop. The steps I need to do to get this working. So far I am having no end of problems getting this new laptop to work with my old software. Using Windows 8 Pro 64 bit on host and Windows XP Pro

I accidentally set "Windows Presentation Foundation Host" to default open in Google Chrome, I don't know why I did. I was experimenting, I guess. I don't know how to fix it.
Windows Presentation Foundation Host is an XAML file. I don't know a whole lot about how computers and their files work, but I know a little like how to navigate with task manager, file explorer, control panel, etc.

If say I have a Windows Guest running its own AV software whether it's Windows defender or anything else then it seems to me that by having the HOST also running an AV software we are going to have two pieces of AV software running on the same data areas (the VM Disks).
It would seem to make sense to exclude the VM directories from the HOST's AV scan when the VM's are running -- but I haven't seen any mechanism to dynamically turn off parts of the AV system -- it's either an ALL or NONE mechanism.
I'm sure the performance of both HOST and GUESTS could be enhanced if AV software was ONLY running on the machines it needed to be - but AV software doesn't seem to allow for excluding certain parts of the machines.
If I have up and running say 4 VM's - that's my normal usage - then on the Virtual Machine directory on the Host I could have 5 (yes FIVE) AV pieces of software scanning / protecting it (The VM directories / data areas) at all times -- The VM's of course need to be individually protected if they are on the Net.

I am having trouble with my computer. A message pops up that Catalyst control center: host application has stopped working. And my PC will inform me when it is working. So I try to restart but it says that the host application is preventing the computer from restarting even though I know that it is not turned on. The problem is that it slows down my computer and even after I think I have solved it it goes back to not working.
The problem has caused me to not being able to use the internet. Also on occasion, when attempting to restart or shut down it took longer than 10 hours (I did not wait for it to complete I then manually shut it down). I have tried resetting it to a date where my computer functioned fine several times but it only solves the problem for a short period.

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.

Initially on Win7, I was manually updating Security Essentials when was offline from this link:
How to manually download the latest definition updates for Microsoft Security Essentials
You choose x86 or x64 and go from there.
What's not mentioned, is that you can use the same links to update Windows Defender on Windows 8 as well.
I've been doing this for quite some time without issues. So the two programs are very much alike.

Which registry settings should I change to set the top two default Windows rules back to 'Unrestricted' ?
I set up some rules in the local security policy some time ago when there was fuss in the news about the cryptolocker virus. They looked a lot like the rules above (I found that screenshot online as I can't take one myself, read on..)
Today I was installing some software that wanted access to the areas I restricted. I temporarily disabled the rules, then re-enabled them. Being a dumbass I also set the top two rules (which are Windows default rules) to Disallowed!
Over the following 10 minutes various aspects of my PC stopped working, telling me that the local security policy prevented access. I couldn't even get into the Control Panel or the Local Security Policy screen to change it back, once I realised what I had done. I rebooted the machine - it won't come back up
I've tried a system restore by booting from the installer on USB (which did not work, it grumbled that it could not restore due a file locked by anti-virus) so I think I've got two options:
Refresh my system using the Windows 8 tools - but I suspect that might leave the LSP rules in place, as it retains my settings & preferences.Hand edit the registry to correct the settings.
Option 2 is looking best, I can get into RegEdit from the recovery console, but I'm not sure what to edit and what to set it to? This is on Windows 8.1 Pro...

I came to some trouble installing CorelDraw software which apparently uses for it's setup launcher web active container performed by IE core. If I launch setup, the setup windows is evidently noninitialized showing the top warning band about active content being blocked for security reasons. Even allowing active content by selecting from the top bar menu doesn't make the setup continue. So now I'd need to temporarily bypass all IE's security checks, ie. allow everything. What I already did was browsing the security tab in IE options and allowing most of the choices in branches ActiveX controls and plugin modules + Scripting (Local Intranet). On Advanced tab I have checked in Security branch Allow execution of active content from CD discs on this computer + Allow execution of active content from files on this computer. Nothing of these affecting the installer to run (ie. I still see then active content blocking bar).

Windows 8.1.1 and Bitdefender Total Security 2014
o.k. long story short before installing 8.1.1 in my real environment i tested it out extensively in vm. i found out that if you get past a certain point with the windows updates bitdefender will not install, if you install bd prior to a certain point it installs and works great even after you do the rest of the windows updates. How to get it installed and working correctly in a fully updated 8.1.1? i have eset smart security in, but i'd rather have my bitdefender.

I am running 8.1, and firefox 25. I can't download or run Avast, or download any executables, suddenly. I lowered my security settings to Medium and added Avast to the firewall permissions, but to no avail. My download settings were already at "prompt" anyway, so there's something deeper I can't figure out. I'm a reasonably competent generalist but not super computer smart.

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

A McAfee technician had to remote control my laptop to get rid of a 'Trial period' of McAfee. She asked me if she could remove 'Malwarebytes' which I had downloaded. She said it contravenes with McAfee's security. Is this a fact? Or maybe they don't like competition!
