When you use Automatic Updates to scan for updates or to apply updates to applications that use Windows Installer, you experience issues that involve the Svchost.exe process...The Svchost.exe process may spike the CPU usage to 100 percent during update detection or update installation. Also, the Svchost.exe process causes the computer to stop responding for various lengths of time...The Svchost.exe process produces an access violation during update detection or update installation...

MS Article ID: 932494 with Hotfix for issues that involve the Svchost.exe process

If the Hotfix does not help, then proceed as follows:
1. Click Start > Run and type: services.msc.
2. Double click the service "Automatic Updates".
3. Click on the Log On tab, ensure the option "Local System account" is selected and the option "Allow service to interact with desktop" is unchecked.
4. Check if this service has been enabled on the listed Hardware Profile. If not, please click the Enable button to enable it.
5. Click on the tab "General"; make sure the "Startup Type" is Automatic. Then click the button "Start" under "Service Status" to start the service.
6. Repeat the above steps with the service: Background Intelligent Transfer Service (BITS)

Re-register Windows Update components and Clear the corrupted Windows Update temp folder.
1. Go to Start > Run and type: REGSVR32 WUAPI.DLL
2. Press Enter.
3. When you receive the "DllRegisterServer in WUAPI.DLL succeeded" message, click OK.
4. Repeat these steps for each of the following commands:

REGSVR32 WUAUENG.DLL
REGSVR32 WUAUENG1.DLL
REGSVR32 ATL.DLL
REGSVR32 WUCLTUI.DLL
REGSVR32 WUPS.DLL
REGSVR32 WUPS2.DLL
REGSVR32 WUWEB.DLL


Since the temporary folder of Windows Update may be corrupted, refer to the following steps to rename this folder:
1. Click on Start > Run and type: cmd
and press Enter.
Type the following command at the command prompt: net stop WuAuServ
(Note, you might need to reboot before the net stop command will work)
2. Click on Start > Run and type: %windir%
and press Enter.
3. In the opened folder, rename the folder "SoftwareDistribution" to "SDold".
4. Click on Start > Run and type: cmd
and press Enter.
5. Type the following command at the command prompt: net start WuAuServ

You can download and use Process Explorer or Glarysoft Process Manager to investigate all running processes and gather additional information to identify and resolve problems. These tools will show the process CPU usage, a description and its path location.
