[does it mean each contains differernt version of file explorer ?] The existence of different versions of File Explorer is due to the evolution of the Windows operating system and the introduction of new features and capabilities over time. Each version of Windows has its own version of File Explorer, which has been updated to include new functionalities and improvements. For example, Windows 95 introduced File Explorer as a replacement for the older File Manager, and subsequent versions have continued to enhance the file management experience. The renaming from "Windows Explorer" to "File Explorer" in Windows 8 reflects this evolution, while the old name can still be seen in the Windows Task Manager

[why restart pc my file eplorer folders many disappeared seemed auto switched to old version ] Issue with folder and files disappearing The disappearance of folders and files in Windows after a PC restart can be attributed to several reasons. It may be due to accidental actions like moving or deleting folders, hidden files due to system settings, or syncing issues with cloud services. Additionally, temporary profile logins or system errors can also cause this issue. To resolve the problem, users can check the Recycle Bin, search for files using the search bar in File Explorer, or enable the "Hidden items" option in File Explorers view settings to reveal hidden files and folders. If the issue persists, further troubleshooting steps such as restarting Windows Explorer, clearing thumbnail cache, or using system restore points may be necessary.

If you were not ready to receive the updates, it is possible that the system decided to install the update to catch up with the latest changes.
