I am new to stackoverflow, and I seem to have a problem with my computer using over 90% of the available memory, even when only Chrome is open.

Here are the symptoms: When I start my computer, it boots up as usual and everything is fine after I log on for a few minutes. I open Chrome and realize that everything is slow (from loading the page to clicking buttons). I then open task manager (which takes around 15 seconds by itself) and find that the process svchost.exe is using over 75% of my memory, with the total memory usage being at around 90 ~ 95%. I realize that svchost is used to run many things, so I go to services relating to that specific process, and these are the ones running:

I've looked online and found something about memory leaks or the Alureon virus? I'm not entirely familiar with computers, so I don't really know what they mean. Do I need to get an antivirus or take it to a shop (Canada Computers etc.)?

I'm not sure if these are the specs needed, but I'm running an Acer Aspire M3203 with an AMD Athlon II X3 425 processor, 3 GB of memory and a 64-bit operating system.

It should be noted that after I end the process tree for process, it restarts again once. After I end it the second time, it doesn't come up until I restart the computer. Please help ASAP. Thank you in advance!

  • What is the image suppose to show exactly? I just normal services. – Ramhound May 21 '15 at 20:20
  • capture a xperf trace which shows the memory usage GROW/Spikes: pastebin.com/peqLGxSa. But WindowsUpdate is a good candidate. For me it uses over 1GB during scan. – magicandre1981 May 22 '15 at 4:25
  • here I've posted my result in Windows 8: superuser.com/a/919777/174557 You can't really fix this. Microsoft must fix this in high memory usgae in the Windows Update DLL – magicandre1981 May 26 '15 at 17:29
  • have you tried the June 2015 WindowsUpdate Client Patch? – magicandre1981 Sep 30 '15 at 4:11

You need to stop the services associated to that SvcHost.exe (as highlighted in your screenshot) one at a time until you find the one that is eating your memory. Based on recent experience, it's most likely Windows Update.

  • Thank you for the answer. I stopped Windows Update first and the memory usage immediately dropped from 89% to 23%. What should I do now? I mean, what is the problem, and do I need professional help for this? – James Leung May 23 '15 at 21:48
  • You could also use Google. ;) Please check(!) whether this hotfix is applicable for you. – Daniel B May 23 '15 at 21:55
  • @Daniel It warns me that I should not install the hotfix for fear of damaging my system if the symptoms are not exactly as described. I don't recall installing Windows Management Framework 3.0 and I can't find it in my installed updates. Should I still continue with the hotfix? – James Leung May 24 '15 at 21:56

One user reported the Windows Update Client for Windows 7: June 2015 fixes his memory usage. Make sure that the update is installed and look if it also fixes your issue.
