Using tabbed browsing again without restrictions(Internet Explorer 7)

              In the browser, several websites can be managed at a time using tabs. Although you have not changed the settings at all, the command ‘New tab’ is nowhere to be seen in the File menu.
              It is perhaps other system settings that are blocking the tab browsing with Internet Explorer. In XP Professional, you can solve the problem with the Group Policy Editor.

              For that, select ‘Run’ in the start menu, enter ‘gpedit.msc’ and press Enter. Navigate to the left in structure to ‘User configuration | Administrative Templates | Windows Components | Windows Explorer’. On the right-side of the window, search for ‘turn on Classic Shell’. If this guideline is activated, it blocks the display of tabs in Internet Explorer. To correct, double-click on it and change the setting in ‘Deactivated’ or ‘Not configured’. Navigate further in the structure to ‘User Configuration | Administrative Templates | Windows Components | Internet Explorer’. On the bottom right of the list, search for the guideline ‘Turn offtabbed browsing’. Set this as well to ‘Deactivated’ or ‘Not configured’.
             In XP Home, you must look for the corresponding registry entries and change them. For that, select ‘Run’ in the start menu, enter ‘regedit’ and click ‘OK’. Then navigate in the RegistryEditor to the key ‘HKEY_CURRENT_USER\Software\ Microsoft\Windows\CurrentVersion\ Policies\Explorer’. Search for the DWORD value ‘ClassicShell’ on the right side. If it is available, remove it with ‘Edit | Delete’ and confirm the security query with ‘Yes’. Then navigate further to the key ‘HKEY_ CURRENT_USER\Software\Policies\ Microsoft\’. Check here, whether the subkey ‘Internet Explorer\TabbedBrowsing’ is available. If that is the case, delete the key ‘TabbedBrowsing’. Then close the registry. After restarting, IE should work properly again.
