Svchost.exe hogs your processorís performance
« on: March 16, 2014, 01:28:18 PM »
A common Windowsí system process, svchost.exe, can start consuming processor cycles it doesnít need. This can make your system feel sluggish, and may even cause it to crash.
There are a few potential causes. The first is malware. Because svchost.exe is a common Windows service, some malware will use it as a disguise, knowing most users have come across svchost.exe before and are unlikely to think itís a virus. You can rule out this possibility by downloading a free anti-virus suite like Avira and scanning your system.
Another potential trigger is the Windows uPNP (universal plug-and-play) service, which scans your home network for compatible devices. The service can get out of hand, scanning continuously and  using resources until no more are left. To fix this, do a Windows search for the Network and Sharing Center, and open it. Then go to Advanced Sharing Settings and turn Network Discovery off.
Finally, some programs install services that can make svchost.exe go bonkers. The most likely culprits include anti-virus apps, backup apps and networking utilities. Try un-installing any software that you installed just prior to the problem arising.
Note that consumption of some CPU resources by svchost.exe is normal, including periodic spikes. You only need to look for a solution if the process is continuously using a significant portion of your processorís power.
