Microsoft’s Windows 7 is the success version of Windows and brought an excellent reputation to Microsoft. Unlike XP, Windows 7 isn’t lightweight version, comes with a lot of new features and functions but still provide a good speed and user experience for users.
I’ve used Windows 7 for years and now still using it. I must say that it’s the best version of Windows operating system for me, based on my opinion. In most cases, it helps me to complete my work smoothly and very fast, without any problems.
However, last week, I noticed a few strange signs after downloading and install some new Windows updates. The clear sign is that I found a svchost.exe (netsvcs) process is hogging CPU resource. After installing Windows updates and rebooting my computer (as Microsoft asked), this system process always uses the resource of my CPU in high status, up to 30%, even I haven’t open any application. At the moment, there’s no other program is running.
After doing many types of search on Google and ask a few experts, turn out this high CPU usage issue is related to recent Windows updates that I’ve installed. My Windows 7 computer only gets back to normal status when uninstalling those updates. The cause is that sometimes new updates aren’t compatible with the current apps and lead to this high resource usage issue.
In fact, along with Windows updates, there are a few other reasons that can lead to svchost.exe high CPU usage error, including interrupted Windows Update, corrupted system files and much more. Let’s find out further by reading this guide.
- Windows Update
If you get this issue after installing Windows updates, then you should navigate to Control Panel -> Uninstall a program and remove any recent updates.
Sometimes, you are unaware that your Windows computer will download and install updates without asking you. The reason is that you have set up it to do it automatically. To find out whether your Windows PC was received any update lately or not, you can go to Control Panel -> Uninstall a program and choose “View recent updates.”
- Corrupted Windows System File
In many cases, corrupted Windows system files can also cause this high CPU usage problem. In order to check and verify system files, run SFC command from Command Prompt. This command will automatically scan and find corrupted system files on your Windows PC and then repair them.
- Affected By Virus
If you don’t have any antivirus program on your computer, I would recommend you to download one to protect it from online threats. It can be affected by many types of viruses, malware or malicious programs and lead to serious issues, including high CPU usage error. After installing, do a full scan to find and remove any types of viruses out of your Windows PC.
- Corrupted Windows Service
You can use Task Manager or Resource Monitor to find out which system function or Windows service was use svchost.exe process and cause the high CPU issue. After finding out, you can turn off those features or Windows services as a temporary solution and then find a way to resolve the problem. That’s the method I often use when there was no other solution to fix the issue permanently.
