Disable Windows Online Help
Although, Windows online help may provide users with the latest relevant content, some organizations may still want to disallow it! Organizations may want to save Internet bandwidth or have to comply with specific security requirements and disallow Windows Help to connect online and download updated content. If this is the case, then I suggest that you disable Windows Online Help functionality from through Group Policy as it will generate errors and prompts, every time it tries to connect to the Internet. You can use the Turn off Windows Online Group Policy to prevent the automatic downloading of online Windows Help content.
You can do this by enabling the following policy setting. Open the Local Group Policy Editor snap-in by typing gpedit.msc in the Start search text box and press enter.
Go to the User Configuration\Administrative Templates\ System\Internet Communication Management\Internet Communication Settings\Turn off Windows Online
Turn off Windows Online – This specifies whether users can search and view content from Windows Online in Help and Support. Windows Online provides the most up-to-date Help content for Windows. If this setting is enabled, users will be prevented from accessing online assistance content from Windows Online.
Also, I would like to share with you a useful Windows 8 handbook for forensic examiners that details the new user interface, artifacts, applications, and the Registry. The content is very similar to Windows 7 while, the guide is written by Amanda C.F. Thomson from The George Washington University, U.S. You can get a copy of teh guide from here – http://propellerheadforensics.files.wordpress.com/2012/04/thomson_windows-8-forensic-guide.pdf
