Description

Technical Field

[0001] The present invention belongs to the technical field of automatic screen locking, and specifically relates to a method for solving automatic screen locking after the disconnection of Windows Remote Desktop Connection. Background Art

[0002] The Windows operating system is widely used in enterprises and individual users. As an important function, the Remote Desktop Connection (RDC) using the Remote Desktop Protocol (RDP) allows users to remotely control another computer from one computer, enabling efficient and convenient remote work. However, there are many inconveniences in the actual application process of RDC. In particular, the phenomenon of automatic screen locking after the connection is disconnected has a significant impact on users' work.

[0003] Specifically, when a user remotely connects to a target computer, if the connection is unexpectedly disconnected due to reasons such as unstable network, system anomalies, or incorrect operations, the target computer may automatically enter the screen-locked state. Although this phenomenon helps to protect the security of the computer, it brings many inconveniences in actual work. For example, if a user is remotely processing important files and the connection suddenly disconnects, the files may not be saved or may be lost; another example is that the interruption of the remote connection forces the user to log in again, which not only wastes time but may also weaken the system security due to frequent re-logins.

[0004] For enterprise-level applications, this phenomenon may also cause greater troubles. When employees within an enterprise remotely access a server or a workstation, once the connection is disconnected and the screen is automatically locked, it will lead to the interruption of data processing and affect work efficiency. Especially in some work scenarios that require continuous processing of a large amount of data, this phenomenon seriously affects the continuity and efficiency of work. For example, in remote operation and maintenance, operation and maintenance personnel need to frequently view the server status and logs. If they need to log in again every time the connection is interrupted, it not only consumes time but may also cause misjudgment of the server status by the operation and maintenance personnel, affecting the quality of operation and maintenance.

[0005] Existing technical solutions include:

[0006] 1. Modify the system registry settings

[0007] A relatively common solution is to adjust the screen locking behavior after the disconnection of the Remote Desktop Connection by modifying the registry settings of the Windows system. Users can manually edit the relevant key values in the registry, such as multiple sub-items under "HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows NT\Terminal Services", to control the Remote Desktop Connection behavior. For example, setting "fDisableLocking" to 1 can prohibit screen locking; setting "fPromptForPassword" to 0 can automatically unlock the screen after disconnection.

[0008] This method of modifying the system registry settings is simple and easy to implement, but it is not 100% successful, and the success rate also varies on different operating systems. In addition, for non-technical personnel, modifying the registry poses certain risks. A slight mistake may lead to system instability or abnormal operation.

[0009] 2. Using third-party software

[0010] There are also some third-party software on the market that can assist in solving the problem of automatic screen locking after the disconnection of the Remote Desktop Connection. For example, some Remote Desktop management tools provide functions such as "Keep Connection" or "Auto Unlock", which can maintain the session or automatically unlock the screen when the connection is unexpectedly disconnected. These software usually have a graphical interface and relatively simple operations, making them suitable for enterprise users in large-scale deployments.

[0011] Using third-party software often requires additional licensing fees and may introduce new security risks after installation, such as vulnerabilities in the software itself or compatibility issues with other parts of the system.

[0012] 3. Custom scripts

[0013] Some technical users control the behavior after the disconnection of the Remote Desktop Connection by writing custom scripts. For example, PowerShell scripts can be used to automatically run the unlock command or the command to keep the session when detecting the disconnection of the Remote Desktop Connection.

[0014] This method of custom scripts is highly flexible, but writing and maintaining scripts requires a relatively high technical level, and it may be difficult to ensure stability in a complex network environment. Summary of the Invention

[0015] In view of the above problems, the present invention is proposed to provide a method for solving the automatic screen locking after the disconnection of the Windows Remote Desktop Connection that overcomes the above problems or at least partially solves the above problems.
