Why does system error 5 occur, access denied?

In this case, your permissions are generally low, win7 administrator directly run cmd is not administrator rights, you have to run cmd as an administrator (right-click--- run as an administrator), then you can net user username add on it.

If the account is not an administrator, you can use net localgroup administrators add username to elevate it.

The main problem I encountered when starting the tomcat service is that the command execution authority is too low, and you need to close the cmd window, and then run the cmd window as an administrator, and then it can be solved.

Introduction to Windows.

Windows means window. In addition, there is a Windows computer operating system launched by Microsoft called Windows. With the continuous upgrading of computer hardware and software systems, Microsoft's Windows operating system is also constantly upgraded, from 16-bit, 32-bit to 64-bit operating systems.

From the initial Windows to the well-known 7, Windows 8, Windows 10 and other versions of Windows continuous updates, Microsoft has been trying its best to develop and improve the Windows operating system.

Features of Windows.

Windows developed by Microsoft is currently the most user-used and most compatible operating system in the world. Support keyboard and mouse function. The default platform is composed of a taskbar and a desktop icon, the taskbar is composed of the running order, the Start menu (Windows changed to the Start screen, Windows 10 changed back to the Start menu), time, the quick launch bar, the input method, and the bottom right tray icon.

And the desktop icon is the way to enter the program. The default system icons are "My Computer", "My Documents", and "**Station". In addition, the built-in "Internet Explorer" icon will be displayed.

Three public core parts of the operation.

windows10

Windows 10 is Microsoft's next-generation operating system. One of the most obvious visual changes is the return of the Start Menu. Windows 8 overemphasizes the touch experience, which has made many Windows users miserable, the most important of which is that there is no Start Menu and no "Classic" of Windows.

The Windows 10 operating system brings a wealth of improvements to the desktop environment, including a new Start menu, a new virtual desktop, a new multitasking view, and a new window-docked snap mode.

The addition of the "Task View" button and related functions to the new system is also one of the new features highlighted by Microsoft. This feature is similar to Apple OS X's Expose feature, which allows you to zoom and arrange all open windows to make it easier for users to quickly find the target task.

4, and then press the F3 key again to delete, until it prompts "No corresponding option found". Duan shouted.
