Win7 Tips Cannot display thumbnails

                  Long before Microsoft officially launched the Windows 7 operating system, it has won the favor of many users with its rich new features and cool display effects. For the "real-time taskbar thumbnail preview" function, Microsoft is still very interesting, basically supported in all Windows7 versions. As long as the user moves the mouse over the taskbar, a preview thumbnail will appear and the visual effect will be unique. But I don't know when, the taskbar preview thumbnail suddenly disappeared. Move the mouse to the taskbar, and it will become a line-by-line text title. It looks really awkward... So, how can I recover it? Since the previous thumbnail preview can be used normally, the hardware should be supported. . As long as the relevant hardware and drivers are working properly, this problem is well solved. Just change the relevant settings. Let me introduce this method for everyone. 1. Please check the remaining space of your C drive immediately. If there are only a few hundred megabytes or tens of megabytes, please clean up the useless files of the C drive or transfer the useful files to other disks. This way the thumbnails will display properly. It is recommended that the system disk keep the remaining space of the disk twice the size of the memory. (The cause of the problem is unknown. It is not clear how many megabytes remain is the critical point set by Microsoft.)
