Hi, this is a two step fix hopefully will get it back for you (will do no harm)
Step1
Click Start, click Run and type Taskmgr and click OK. This opens Task Manager. Click the Process tab. Stop all of the following processing if running:
helpsvc.exe
helphost.exe
helpctr.exe

Step 2
Reinstall Help and Support
Click Start, click Run and type CMD, and click OK.
In Command Prompt, type the following commands and press Enter after each line: (Alternately, create a Batch file and run.)

net stop helpsvc
cd /d %windir%\pchealth\helpctr
rd packagestore /s /q
rd installedskus /s /q
cd binaries
start /w helpsvc /svchost netsvcs /regserver /install
start /w helpsvc /register

Some of these commands can take awhile to run (especially the second last one) so be patient. If this fails:-

From a CMD prompt you can try windows file verification checker at the prompt type sfc /scannow press enter you may be asked for your XP cd.
