I have noticed my computer is slower these past days. So I looked at my task manager, and found a bunch of service hosts. I don't know what they are and if they're slowing my computer down. What are they?

They are normal, and they are not slowing your computer down.
Something else is. A malware infection perhaps.

Hi,

Yes the names will appear to be the same yet the underlying program action will be different.

In Task Manager - Processes tab double click each to expand it for a little more information.

=======================================================

Are you using a 3rd party antivirus/antispyware/security program? If so many of those

can cause startup slow downs.

Check with the System Maker Support (Motherboard Maker for custom systems), their

on-line documentation and drivers, and ask in their forums about any known issues.

Update the BIOS, low level chipset drivers, and the major on-board and separatedevice drivers (all of those can have a definite impact on boot speed and performance).

Note using Win Key + X and Win Key + W (to get to Control Panel, Run, and Settings

as needed). Win Key + D calls the desktop and the using Win Key toggles Desktop and

Start Screen.

Check Startup Programs.

Right Click in the lower left hand corner - Task Manager

Or WinKEY + X - Task Manager

Or Right Click the Taskbar - Task Manager

Check the StartUp tab.

If needed : 

Try doing a "Refresh your PC without affecting your files" (or changing your personal

settings) or even a Restore. Be prepared to re-install the programs, Apps will remain.

And having redundant backups of your files off of the main hard drive is always a

good idea.

Windows 8 includes special methods to Refresh (keep files and settings)  or a Reset

(new install removing all).

Is it normal to have to service hosts of the same name, e.g.: Service Host: Local System (Network Restricted)?
