Background

1) Check the Windows background mode (most common)​

1. Right‑click an empty area on the desktop → Personalize
2. Go to Personalization → Background
3. Look at the “Personalize your background” drop-down:
   • If it says Slideshow → change it to Picture or Solid color
   • If it says Windows spotlight → change it to Picture or Solid color
4. If you want a solid color:
   • Select Solid color and pick the color you want

2) Make sure a Theme isn’t changing it​

1. Settings → Personalization → Themes
2. Choose a basic theme (or “Windows (light/dark)”) and then re-set Background to Solid color
3. Also check: Personalization → Colors
   • Turn Off “Automatically pick an accent color from my background” (optional, but can make things seem like they’re changing)

3) If it still changes: look for syncing or a wallpaper app​

A) Turn off theme syncing (if you use a Microsoft account on multiple PCs)​

1. Settings → Accounts → Windows backup (or Sync your settings depending on build)
2. Turn Off syncing for Personalization / Theme

B) Check for Dell/3rd-party wallpaper software​

1. Settings → Apps → Installed apps
2. Look for anything like “Wallpaper”, “Dynamic”, “Changer”, “Spotlight”, “Dell…”
3. Uninstall/disable it temporarily to test

4) Quick questions so I can narrow it down​

1. Is it changing on the desktop background, the lock screen, or both?
2. In Settings → Personalization → Background, what does the drop-down currently say: Solid color / Picture / Slideshow / Windows spotlight?
3. About how often does it switch (every minute, hourly, daily, after restart)?

1) Desktop background slideshow​

• Settings → Personalization → Background
• If it’s set to Slideshow, switch to Picture (or Solid color).

2) Lock screen slideshow / Windows Spotlight​

• Settings → Personalization → Lock screen
• If it’s Slideshow or Windows spotlight, change to Picture (or disable slideshow).

3) Screen saver (can look like a slideshow)​

• Settings → Personalization → Lock screen → Screen saver
• Set to (None), or if it’s “Photos”, disable it.

4) Photos app or a viewer launching at startup​

• Task Manager → Startup apps
  • Disable anything like Microsoft Photos, Photo viewer, Wallpaper, Slideshow, OEM media, etc.
• Also check the Startup folders:
  • Press Win+R → type shell:startup
  • Press Win+R → type shell:common startup
  • Remove any shortcut that launches a slideshow/viewer.

5) Task Scheduler (common for “it starts by itself”)​

• Start → search Task Scheduler
• Look under Task Scheduler Library for anything that triggers At log on or At startup and launches a photo/viewer/wallpaper app.

6) If it’s only happening in a browser​

• Edge/Chrome settings: “On startup” → set to Open the New Tab page (instead of “Continue where you left off”).
