So, you got a lot of questions on your mind.”Why my PC got slowdown? Is it a virus? Have someone got into my network and uses it? Or is it a malware type of attacks?” No. It’s because of background services called “svhost.exe” which running on your PC that consumes lot of RAM.

Windows svhost.exe:

Svchost.exe is a process on your computer that hosts, or contains, other individual services that Windows uses to perform various functions. For example, Windows Defender uses a service that is hosted by a svchost.exe process.So, how can we reduce the RAM consumed by this services.Fortunately, high CPU usage is usually easy to fix.

Step 5: Services

Now right click on the process with large CPU usage, click Go to Service(s), as shown above in the image.

Step 6: List of Services

Now the Windows Services executed by the svhost.exe processes will be shown above.

Here, we are going to stop the “Windows Update” services. Other services are needed by the pc hardware plugins.so forget about other services.

Click Apply and OK.

Step 12: Windows Search and Super Fetch

In addition to that you can stop the following services to reduce the CPU usage. They are

1. WINDOWS SEARCH

2. SUPER FETCH

1. “Windows Search” : Windows Search is a desktop search platform that has instant search capabilities for most common file types and data types, and third-party developers can extend these capabilities to new file types and data types. You can turn off Windows Search if you don't use it

2. “Super Fetch” : Super fetch is a service that was introduced with Vista and has been part of Windows ever since. It tries to speed up your computing experience by pre-loading parts of programs into memory with sometimes detrimental effects as you had to experience. It tries to determine which software you use and stores parts of it to the Windows folder.

Unfortunately, Super fetch doesn't always get it right which software you're going to use and can keep your hard drive busy for minutes after booting. I found it especially annoying since it kept on loading software I wasn't even going to use or that I had only used once. Since I use a plethora of different programs every day, Super fetch actually had a massive negative impact on my computer's performance with keeping the hard drive busy for 5-10 minutes after a fresh boot. This is the very reason I have been running Windows with de activated Super fetch ever since it came out.

Step 13: Stop Windows Search and Super Fetch

Now repeat all the above procedure to stop Windows Search and Super Fetch services

Step 14: Final Result

Now, the above steps will reduce the CPU usage as shown above.

<p>The memory leak of windows update should be corrected by a patch without desactivating the service (it worked for me).
