What should I do if the Win7 system desktop cannot be automatically refreshed?

This phenomenon is not something that everyone has. Sometimes the computer suddenly has a strange phenomenon. For example, if the desktop file is deleted, the file name of the desktop is renamed, but the file name is still changed. If you delete or change it again, you will be prompted: XXXX refers to an unavailable location, or a hard drive on a computer connected to the Internet's local network.... If you refresh the desktop, you will see that the changes you made before come out again. It turns out that this is because the desktop of the system is not automatically refreshed. The normal desktop operation will refresh the desktop after the operation, so we only need to set the desktop to automatically refresh to solve the problem.

1, generally this problem is mostly the system does not have this setting, we have to add an item in the registry. First run the input regedit, and then open HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Control. Right click on the control and select New - Item, name it UPData, then right click on UPData is still a new - item, named UpDataModel (after practice It is found that it is also possible to create an UpDataModel and create a new value directly on UPData.

2, then click the right mouse button on the right side of the registry: New - expandable character 窜 value

3, finally rename the newly created one to DWORD, double-click the value Change to 0, 0 for refresh, 1 for no refresh. After you finish the computer, you can restart the computer and don't enter the wrong value, otherwise it will not work.
