When working in applications that edit certain files, a certain number of previous steps of file changes are automatically saved. In some cases, the story is preserved in its entirety, in others - only part of it. The function of restoring the original state is almost everywhere available, however, provided that the file was not saved during processing.
Instructions
Step 1
If you need to undo recent changes related to entering and formatting text in the editor, browser window, and so on, just press the Ctrl + Z keyboard shortcut. Also in the text editor MS Office Word there is a special button on the toolbar, which is responsible for undoing the latest changes. Another option is to use the menu "Edit", "Undo". In this case, if the document editing process was saved earlier, a return to the previous position is possible.
Step 2
If you need to undo the latest changes related to editing images in Adobe Photoshop, use the Alt + Ctrl + Z keyboard shortcut or click the Edit menu item, then select Step Back from the drop-down menu.
Step 3
If you want to completely restore the file, press F12. If you have already saved your changes, then you will not be able to undo them. When editing graphic files, it is generally best to create and edit copies of them, and keep the originals separately. Also view the history of changes in a special table of changes, which is available from the "Window" menu item.
Step 4
If you want to undo the last changes that affected the operation of your computer (for example, installing updates, programs, utilities), open the Start menu, select the menu of standard programs, then System Tools, and finally System Restore. A large window for restoring the operating system will appear on the screen, select on the program's calendar a checkpoint for saving parameters before making changes to the system, roll back to this date
Step 5
Keep in mind that before doing this, it is best to save the personal data that you use when using the applications installed during this period, as the programs will be removed along with them. These can be various account logins and passwords, key files, links, and so on.
