Don"t have sầu any restore point or system image? No worry. Based on the details above sầu, here I recommover you select "Commvà Prompt" khổng lồ restore the registry.

The registry is a database that contains the configuration data for the Windows operating system and most of the applications. That is why changes in the registry may influence the functionality of your computer or programs. Registry files may get deleted accidentally by yourself or by some program.
