Adjust the TDR mechanism: Modify the TdrDelay value in the registry to extend the system waiting time; 3. Check the graphics card hardware status: monitor the temperature, power supply, interface connection and memory module; 4. Check system interference factors: run sfc/scannow to repair system files, uninstall conflicting software, and try safe mode startup to confirm the root cause of the problem. In most cases, the driver problem is first handled. If it occurs repeatedly, it needs to be further deepened.

UAC frequently pops up because the running program requires administrator permissions or the system setting level is too high. Common reasons include installation of software, modifying system settings, running third-party tools and other operation triggers. If using an administrator account, UAC only confirms the operation and not blocks. The methods for reducing prompts include: canceling the program to run as an administrator, lowering the UAC notification level, using a standard user account, and starting the program through the task planner. It is not recommended to turn off UAC completely because it can effectively prevent malicious programs from tampering with the system. You can set the UAC to "notify only when the program changes the computer" to balance security and experience.

If it exceeds the Windows default 260-character limit, it can be solved by shortening the folder name or enabling long path support; 3. Troubleshoot permission problems and drive letter mapping, run the program as an administrator, confirm that the network drive is correctly mapped and check the UNC format, and restart the application to refresh the connection if necessary.

Software keyboard loggers capture keyboard input through the background running and are often used to steal sensitive information. It may be installed through malicious downloads, phishing emails, disguised updates, etc., and hide processes or modify attributes to evade detection. To detect the keyboard logger, you can 1.
