How do I log on when I log on by ctrl+alt+delete the key combination? Teach you the following methods:
Click Start--> run on the desktop taskbar to enter gpedit.msc in the pop-up window.
When you enter gpedit.msc, click OK to open the Group Policy Editor. In the left box of the Group Policy Editor, sequentially expand (the "+" number before the point)--> Computer Configuration-->windows setting--> security Settings--> Local policy, at which point "security options" are available under local policy, click "Security Options" in the box on the right to find " Interactive logon: Do not press Ctrl+alt+del "
Right-click "Interactive login: Do not press Ctrl+alt+del", click "Properties" in the pop-up menu, and click the Circle before "enabled" in the Properties tab to select it.
Confirm the circle in front of "enabled" after a small black point, click OK, and then close the window. You don't have to press the "Ctrl+alt+del" key to log in after you start your computer.
