In order for the application to work smoothly on Windows 7, you need to activate the Windows Aero feature. This problem is caused by the Windows 7 operating system. No problems were detected in Windows 8 and later versions.

The video about this problem and its solution in Windows 7 is presented below for your information.

Features

Renaming

The renaming feature in the UI application is used to make it harder for other applications to detect the protection application (sprotector). By activating this feature, the sprotector application runs with a random name each time. The UI application is needed to use the feature.

Run at system startup

When running with normal permissions: The application does not require administrator permissions. When using the UI application, when the startup feature is used, the startup settings are made in the HKEY_CURRENT_USER area of ​​the Registry.

When running as administrator: The UI application may be run as administrator for various reasons. When running in this manner, the startup settings are made in the HKEY_LOCAL_MACHINE area of ​​the Registry.

Notes

Please run the UI application in an empty folder. The UI application cleans the exe files in the directory it is located in during the protection activation and deactivation stages. (Temp file cleaning)

To run the protection application without needing the UI tool, use the extract feature in the UI. When you perform this operation, the _screenprotector.exe application is extracted to the UI directory. You can use this extracted protection application with its parameters.

Make sure you save the settings you made for the UI application before activating the protection so that they can take effect.
