Introduction
Windows screensavers (.scr files) are executable files that display animations or slideshows when your computer is idle. Unlike standard screensaver options, custom .scr files offer personalized experiences. This guide explains the installation process in four simple steps.
Step 1: Obtain the .scr File
Download from trusted sources (developer websites or official repositories)
Ensure the file isn't blocked by Windows (right-click → Properties → check "Unblock")
Store in an accessible location (e.g., C:\Windows\System32)
Step 2: Install the Screensaver
Right-click the .scr file
Select "Install" from the context menu Alternative method: Copy the file to System32 folder manually
Step 3: Configure Settings
Open Settings → Personalization → Lock screen
Click "Screensaver settings"
In the dropdown menu, select your installed .scr file
Set wait time (recommended: 5-15 minutes)
Check "On resume, display logon screen" for security
Step 4: Test Functionality
Click "Preview" to verify proper installation
Wait for the set duration to observe automatic activation
Adjust settings if the screensaver doesn't trigger
Troubleshooting
If missing from the list: Reinstall or check file integrity
For security warnings: Add exception in Windows Defender
Black screen issues: Update graphics drivers
Conclusion
Custom .scr screensavers transform your idle screen into a dynamic display. Remember that screensavers no longer prevent monitor burn-in on modern displays, serving primarily for aesthetics or brief security locks.
