    Lightbulb svchost.exe file in Windows explained

    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.

    There can be multiple instances of svchost.exe running on your computer, with each instance containing different services. One instance of svchost.exe might host a single service for a program, and another instance might host several services related to Windows. You can use Task Manager to view which services are running under each instance of svchost.exe.

    To view which services are currently running under svchost.exe
    1. Open Task Manager by right-clicking the taskbar and then clicking Task Manager.
    2. Click the Processes tab.
    3. Click Show processes from all users. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.




    4. Right-click an instance of svchost.exe, and then click Go to Service(s). The services associated with the process are highlighted on the Services tab.

    Note: If you install a program and begin receiving notices that Data Execution Prevention (DEP), a security feature of Windows, is closing svchost.exe or other Windows processes, the cause could be services or extensions created by the program. Check with the publisher of the program to see if there is an updated, DEP-compatible version available, or try uninstalling the program.

    The legit MS svchost.exe file, is situated in the system32 folder. If it is found anywhere else, it, in all probability could be malware. Malware writers also love to change the spelling a bit and call it scvhost.exe and place it in the system32 folder, to confuse people. Just a small tidbit on the subject.

    good review,
    Thank you
    you may also take a look here

    svchost.exe - What is svchost.exe?

    there are some viruses related to this important Windows file, as HappyHandiK noticed.

    Please do not download the "free registry scanner" they advertise: it's not a rogue but it's not free like it claims to be

    Kundoh, this is normal. You will have a dozen or more. Download and run Process Explorer . When you hover over the individual SVCHost.exes, it will tell you what they are used for.
