When encountering the blue screen error VIDEO_TDR_FAILURE(nvlddmkm.sys), priority should be given to troubleshooting graphics card driver or hardware problems. 1. Update or rollback the graphics card driver: automatically search and update through the device manager, manually install or roll back to the old stable driver using NVIDIA official website tools; 2. 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.

The Facebook name change process is simple, but you need to pay attention to the rules. First, log in to the application or web version and go to "Settings and Privacy" > "Settings" > "Personal Information" > "Name", enter a new name, and save it; secondly, you must use your real name, it cannot be modified frequently within 60 days, it cannot contain special characters or numbers, and it cannot be impersonated by others, and the review does not pass the auxiliary verification such as uploading ID cards; it usually takes effect within a few minutes to 3 working days after submission; finally, the name change will not notify friends, the homepage name will be updated simultaneously, and the old name will still be displayed in the history record.

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.

When you encounter a prompt that "update is not applicable to your computer", most of it is caused by mismatch in the system or hardware. Solutions include: 1. Make sure that the system version is consistent with the update package, and prioritize the use of Microsoft official updates; 2. Check whether the system type (32-bit/64-bit) matches; 3. Run sfc/scannow to repair the system files; 4. Check whether the hardware meets the update requirements, such as memory, disk space and TPM modules, etc.; 5. Enter the BIOS to check the relevant settings if necessary.

Choosing a portable application or installing an application mainly depends on the usage scenario. 1. Installing the application will integrate the system in depth, distributed in multiple directories, and may modify settings and add background services. Uninstalling requires system uninstallation tools; 2. Portable applications do not need to be installed, all files are concentrated in one folder, and the system settings are not changed during runtime. Delete only requires directly removing folders; 3. Installing the application is suitable for scenarios where automatic updates, deep system integration and offline functions are required; 4. Portable applications are suitable for users who use multiple devices, system diagnosis or prefer lightweight tools. Both have their own advantages and disadvantages and should be chosen according to specific needs.
