The revamped Photos app in Windows 11 comes with modern UI elements, improved editing tools, and several AI-powered features like OCR and content detection. While these enhancements make the app more powerful, many users have started noticing that the Photos app slows down their PC—especially during startup, while loading images, or when running in the background.
Now, since you’re here reading about this issue, we’re guessing the Photos app is consuming too much RAM or CPU on your Windows 11 PC, causing lag, app freezes, slow multitasking, or even system-wide slowdowns. Don’t worry—you’re in the right place. In this in-depth guide, we’ll cover the most effective methods to stop the Photos app from slowing down your Windows 11 computer.
Why the Photos App Can Slow Down Your Windows 11 PC
Before we jump into the solutions, let’s quickly understand the main causes:
- High RAM usage due to AI features
- Indexing of large photo libraries
- Background processes running constantly
- Corrupt Photos app data or cache
- Outdated or buggy app versions
- GPU acceleration glitches
- Too many photos synced with OneDrive
If you’re facing any of these problems, the methods below will help restore your PC’s performance.
1. Disable AI Features and Automatic Enhancements in Photos App
The Windows 11 Photos app includes background AI processing for:
- OCR (text extraction)
- Content detection
- Automatic tagging
- Smart enhancements
- OneDrive photo syncing
These features can keep your CPU and RAM busy even when you’re not actively using the app.
Steps to Disable AI Features:
- Open the Photos app.
- Click the three-dot menu (top-right).
- Select Settings.
- Scroll down to these options and turn them OFF:
- Automatic enhancements
- People detection / face grouping
- Content-based suggestions
- Linking to OneDrive (if not needed)
- Text extraction / Preview features
Disabling these features stops background scanning and processing, reducing CPU usage dramatically. If your PC feels sluggish when Photos is open, this should make an immediate difference.
2. Repair or Reset the Photos App (Fixes Corrupt Data)
Corrupt cache or configuration files can slow down the Photos app or cause it to load sluggishly.
Windows offers two built-in repair options.
Repair the Photos App
This preserves your data.
- Open Settings → Apps → Installed apps.
- Search for Microsoft Photos.
- Click the three dots → Advanced options.
- Click Repair.
Check if the slowdown is resolved.
Reset the Photos App
This restores Photos to factory default settings. You may lose some preferences.
- Same steps as above, then click Reset.
- Restart the Photos app.
Repairs fix damaged files, and resets remove bloated caches or problematic feature flags.
3. Stop Photos From Running in the Background
Windows 11 apps often run in the background to send notifications, sync libraries, or pre-load features. The Photos app doesn’t need this permission and it can slow down your system.
- Open Settings → Apps → Installed apps.
- Select Microsoft Photos → Advanced options.
- Under Background app permissions, select: Never
Background processing is one of the leading causes of high memory and CPU usage. Turning it off frees resources instantly.
4. Disable Photos Indexing and Reduce OneDrive Sync Load
If your PC has thousands of images spread across different drives or synced with OneDrive, Photos will automatically index them—which uses CPU, memory, and disk.
Reducing indexed folders can improve performance significantly.
Disable Photos from Indexing Large Folders
- Open Settings → Privacy & security → Searching Windows.
- Click Advanced indexing options.
- Click Modify.
- Uncheck large folders like:
- Downloads
- External drives
- Entire partitions
- OneDrive folders (if not needed)
Click OK to save changes.
Limit OneDrive Photo Sync
If OneDrive is syncing thousands of files, Photos becomes slow.
- Click the OneDrive icon on the taskbar.
- Open Settings.
- Under Sync and backup, disable:
- Photos from camera roll
- Large folder syncing (optional)
Wrapping Up
And that brings us to the end of our comprehensive guide on 4 ways to fix the Photos app slowing down your Windows 11 PC. Whether the app is hogging memory, running background processes, or indexing too many folders, you can easily regain system performance using the methods outlined above.
