Differences between screen savers in different versions of Windows?
Screensavers are a long-established feature in Windows operating systems that has changed only slightly across versions. However, there are some differences in location , activation method and compatibility .
Differences in screen savers in different Windows versions
Screen saver files have the file extension .scr and are located in the following locations by default:
- Windows 10, 11, 12 :
- `C:\Windows\System32\`
- `C:\Windows\SysWOW64\` (on 64-bit systems)
- Windows 7 and 8.1 :
- Also in `C:\Windows\System32\` and possibly `C:\Windows\SysWOW64\`.
Manually installed or downloaded screen savers can also be located in other directories, e.g. in the Downloads or Desktop folder .
2.) How to find screensavers with the scr extension
To find all `.scr` files on the system, you can use the Windows search :
1. Open Windows Explorer .
2. In the search field at the top right, enter:
`*.scr`
3. The system will list all screen saver files, regardless of where they are stored.
Alternatively, you can also use the command prompt :
dir C:\ /s /p *.scr
This will search the entire C: drive for `.scr` files.
3.) How to activate a screen saver:
Manual activation via system settings:
1. Open Settings :
- Windows 10: Start menu → Settings → Personalization → Screen saver .
- Windows 11: Start menu → Settings → Personalization → Lock screen → Screen saver settings .
2. Select a screen saver from the list and set the waiting time.
Activating a specific `.scr` file:
- A `.scr` file can be run directly by double-clicking it to test it.
- Right-click → Install to set it as default screen saver.
4.) Compatibility of `scr` files with Windows versions
Most .scr files are universally compatible and work on all versions of Windows, including Windows 10, 11 and 12. However, there are a few points to keep in mind:
- 32-bit vs. 64-bit : Some older `.scr` files might have problems on 64-bit systems, but are often workable via compatibility settings.
- UAC (User Account Control) : Some screen savers require elevated privileges (administrative rights) to work correctly.

Advanced users can configure screen savers directly through the registry :
1. Open the registry editor (`regedit`).
2. Navigate to:
`HKEY_CURRENT_USER\Control Panel\Desktop`
3. Important keys:
- `ScreenSaveActive` = `1` (enable), `0` (disable)
- `SCRNSAVE.EXE` = path to the `.scr` file.

- Screen savers can be password protected. This feature is particularly useful in environments where the screen needs to be protected from unauthorized access.
