Slammr Posted August 23, 2016 Share Posted August 23, 2016 Can you give us some system specs? How full is your HDD? When was the last time you defragged it? Got any new(ish) programs recently installed? What is task manager telling you when you open it? Link to comment Share on other sites More sharing options...
PhantomTweak Posted August 24, 2016 Share Posted August 24, 2016 And how many programs are you trying to run at the same time? Sounds like you set up a flight, then go do other things. Pat☺ [sIGPIC][/sIGPIC] Had a thought...then there was the smell of something burning, and sparks, and then a big fire, and then the lights went out! I guess I better not do that again!

johnhenson Posted August 24, 2016 Author Share Posted August 24, 2016 It happens without me running anything, such as after a restart. Link to comment Share on other sites More sharing options...
johnhenson Posted August 25, 2016 Author Share Posted August 25, 2016 So i finally managed to resolve the issue, and it was due to this process called svchost exe Link to comment Share on other sites More sharing options...

alaskancrab Posted August 27, 2016 Share Posted August 27, 2016 So i finally managed to resolve the issue, and it was due to this process called svchost exe oh god what horrible advice!!! Here's a tip... let the service run overnight. It's probably just indexing your hard drive for the search feature. This can take quite a long time, similar to how long it would take to scan your entire storage for viruses. Link to comment Share on other sites More sharing options...
longbreak754 Posted August 27, 2016 Share Posted August 27, 2016 Simply stopping a svchost.exe is not a good idea - doing so will also stop all services/apps that are using that particular entry - this can lead to system instability. WRT the svchost.exe - if you look in task manger you will usually see multiple entries for it running at the same time. In the case of the OPs problem I would think that the one causing the problem will be the one using most memory - a very likely candidate will be the one labeled svchost.exe (NETSVCS) as this is the one that will normally be used by most programs when they try to run update or activation routines. Unfortunately, such activity as experienced by the OP, especially if it has only recently started and no new installs of the software has taken place, can be an indication of either a virus or malware. The correct way to investigate this issue would be to use task manger/resource monitor to identify the svchost.exe that is causing the issue - it will be the one using most memory and/or CPU time. Once identified, select the entry by left clicking on it and then right click and select Go to Service(s) from the resulting menu. This will open the Services page and the specific services using the .exe will be highlighted - scroll to find the service that is using most memory. Use google to get a detailed explanation of what the service does and if there are any know issues/fixes for it. Do the same for all entries if you wish but the likely culprit will be the one using the most or possible second most memory - the difference in comparison to that used by other services will usually be large. Whilst the problem could simply be a service is running to get an update and failing for some reason - if the service is a valid one use event viewer to find out why is it is failing - the first thing I would do is run a full AV scan and a full malware scan to rule out that being the cause.

g8tr Posted August 27, 2016 Share Posted August 27, 2016 I had the exact same problem. Task Mgr told me that svchost.exe was using massive cpu. I then went in and found that it was the Windows Update that was running. I stopped that one component and svchost cpu use immediately dropped. The Windows Update periodically returns on restart, so I just shut it down and fly with no problem. Link to comment Share on other sites More sharing options...

tberty Posted January 20, 2017 Share Posted January 20, 2017 See http://solution 4 here Just let the updates run. It seems you are spamming here, not trying to help g8tr at all. In case of getting issues with Windows Update, install new updates don't help at all. The thing is that there is something goes wrong with Windows Update and its settings. @g8tr: If you haven't resolved this issue yet, I would suggest you uninstall any Windows updates you have installed lately. Also, you need to clean up the SoftwareDistribution folder as well. https://usefulpcguide.com/18385/svchost-exe-netsvcs-high-cpu/ According to a post I found in Google, when search for svchost.exe (netsvcs), In case of getting issue with Windows Update, you can visit the following link (Microsoft.com) to download Windows Update Troubleshooter to troubleshoot the issue. http://go.microsoft.com/?linkid=9830262 Fixing Windows Update with DISM or System Update Readiness tool is also an option. https://support.microsoft.com/en-us/help/947821/fix-windows-update-errors-by-using-the-dism-or-system-update-readiness-tool Link to comment Share on other sites More sharing options...
