That System Restore affects Windows system files, programs, and registry settings. It can also make changes to scripts, batch files, and other types of executable files on your computer. Thus, any recently
installed programs, updates, or changes to configuration will be lost if you use System Restore. However, make note that System Restore does not affect personal files, such as e-mail, documents, or photos, so it cannot help you restore a deleted file.
