Your web browser can be configured to delete your Internet history automatically. To stop your browser from automatically deleting your Internet history, you have to adjust your browser's option settings. Users can also manually delete the web browser's Internet history. To prevent manual deletion by an Internet Explorer web browser, the administrator of a computer can configure the group policy settings to deny users access to the delete browsing history options.
Launch your Internet Explorer web browser.
Open the "Tools" menu and select "Internet Options." In the Browsing History section, click the "Settings" button to open the Temporary Internet Files and History dialogue box.
Click on the up arrow next to the "Days to keep pages in history" field box located in the History section of the Temporary Internet Files and History dialogue box. Raise the value to coincide with the number of days you would like Internet Explorer to save your browsing history.
Click "OK" to apply your new settings. Click "OK" again to close the Internet Options dialogue box.
Launch your Firefox web browser.
Open the "Tools" menu and select "Options." Click on "Privacy" in the options menu. Click on the box next to "Firefox will" and select "Use custom settings for history" from the drop-down menu.
Clear the check mark from the box next to "Automatically start Firefox in a private browsing session" (if applicable). Check the boxes next to "Remember search and form history," "Remember download history," and "Remember my browsing history for at least..." Then enter the number of days you like would Firefox to save your browsing history. Clear the check mark from the box next to "Clear history when Firefox closes."
Click "OK" to apply the setting and close the Options dialogue box.
Log onto your computer using an administrator account.
Open the Group Policy editor. Click "Start," select "Run," and enter "gpedit.msc" in the "Open" field box (Windows XP). Click "Start," enter "gpedit.msc" in the "Search" box, then click on it in the search results (Windows 7 and Vista).
Double-click "User Configuration" in the right-side window panel. Double-click "Administrative Templates." Double-click "Windows Components." Double-click "Internet Explorer."
Click on the "Settings" bar in the right-side window panel. This puts the list of settings options in alphabetical order. For Windows XP--locate and double-click on the entry for "Disable changing Temporary Internet files and settings," select "Enable," click "Apply," then "OK." Repeat for "Turn off 'Delete Browsing History' functionality," and "Disable 'Configuring History'." For Windows 7 and Vista--locate and double-click on the entry for "Prevent the deletion of temporary Internet files and cookies," select "Enable," click "Apply," then "OK." Repeat for "Turn off 'Delete Browsing History' functionality," and "Disable 'Configuring History'."
Close Group Policy editor. Now when users open the Internet Explorer and the "Internet Options" dialogue box and the "Temporary Internet Files and History Settings" dialogue box, the "Delete" button, the "Move Folder" button, and the "Day to keep in history" field box will be greyed out. This prevents users from manually dumping Internet history from Internet Explorer.
