Why do I need to update Adobe Flash Player (and should I)

You don't need to update Adobe FlashPlayer again, because Adobe has stopped supporting it at the end of 2020. 1.Flash was used to run web animations, videos and interactive content, but due to security vulnerabilities, performance issues and lack of mobile support, it has gradually been replaced by HTML5 and other technologies. 2. Updating Flash is no longer safe, and modern browsers are no longer supported. 3. If you want to access old version of Flash content, you can use an emulator such as Ruffle or the Flash collection of the Internet Archives. In short, continuing to use or update Flash may be risky, and safer alternatives are recommended.

How to fix 'software not responding' without losing data

When encountering "software response", you should first confirm whether it is a false stutter. If it really crashes, try to restore through the task manager. After the end, you can find the automatic save file and pay attention to daily preventive measures. 1. First observe the mouse, interface or hard disk light to determine whether it is running; 2. Use the task manager to try to switch to the program or end the task (note the risk of data loss); 3. Check the automatic save path, cloud synchronization or undo changes to retrieve the data; 4. Avoid opening programs more frequently, cleaning caches, updating the system, and consider using SSD hard disk.

Can I uninstall Microsoft Edge

Microsoft Edge can be uninstalled, but because it is a Windows system component, it cannot be uninstalled directly through the control panel like ordinary software. 1. Use a command prompt (administrator permissions) to uninstall the Edge installation package; 2. You can disable or replace Edge with the help of third-party tools; 3. Enterprise users can manage through Group Policy. Even if uninstalled, it may still be redeployed when the system is updated. Alternatives include: setting other browsers as default, manually removing the Edge icon, and hiding Edge using scripts. Users suitable for uninstallation include system geeks, enterprise unified management needs, and low-end device users who want to release resources. Ordinary users only need to change the default browser to avoid interference.
