Q: My notebook is pre-installed with the Windows 7 base version, I do not know why the desktop does not have a recycle Bin? It's awkward to use XP. In addition, there is a toolbar on the top of the screen, do not know what the reason is missing, how to restore it?
A: Windows 7 has a lot of changes compared to Windows XP, and the Recycle Bin is really hidden. It's not hard to get windows 7 to display the Recycle Bin, just open the organization menu in the upper-left corner of the computer, click Folders and search options, check the two options under the Navigation Pane, and finalize.
As for sidebar, it should be caused by the UAC feature you disabled. If you want to disable UAC and want to use the sidebar, please register the great God help you, locate: hkey_local_machinesoftwaremicrosoftwindowscurrentversionsidebarsettings, Then create a DWORD value, named "Allowelevatedprocess" and assign the value of "1", and finally reboot the system!
