Windows 11 Opera question on Microsoft Windows 11 Pro

Hi NGDRB — sorry Opera’s giving you trouble. A few quick questions first so I can target the advice:

• Does Opera freeze the whole PC or just the browser window/tab(s)?
• Does it hang on startup or after some time/use (e.g., when you open a site, play video, or a particular extension runs)?
• Which Opera build are you using (Regular, GX) and approx. version (Settings → About Opera) if you can check?
• Did anything change recently (Windows update, GPU driver, new extension, new antivirus)?
• Did you try attaching logs or a screenshot? I don’t see any attachments — nothing came through. If you tried to upload, please try again.

While you answer, try these steps (ordered from easiest → more advanced). I include why each step helps and how to undo anything risky.
Quick checks (fast, low risk)

1. Restart Opera and Windows
   • Close Opera, use Task Manager (Ctrl+Shift+Esc) → Processes → End task on any opera.exe. Then start Opera again.
   • Why: kills hung processes and frees locked resources.
2. Test whether the problem is Opera-specific
   • Open another browser (Edge/Chrome). If they also hang, it may be system/driver issue. If only Opera, continue below.
3. Start Opera without extensions
   • Open a Run box (Win+R) and run:
     "C:\Program Files\Opera\launcher.exe" --disable-extensions
   • Or open Opera in private/incognito mode (Ctrl+Shift+N) which disables most extensions.
   • Why: a bad extension often causes freezes. If Opera works, disable extensions one-by-one via opera://extensions to find the culprit.
4. Disable hardware acceleration
   • If you can open Opera: go to Settings → Advanced → System → turn off "Use hardware acceleration when available", then restart Opera.
   • If Opera won’t open: run with flags: launcher.exe --disable-gpu --disable-software-rasterizer
   • Why: GPU driver or acceleration bugs frequently lead to hangs.

Medium steps (profile/cache / settings)

1. Clear cache and cookies for a quick test
   • Settings → Privacy & security → Clear browsing data → select Cached images and files (you can try only cache first).
   • Why: corrupted cache can freeze rendering.
2. Try a fresh profile (safe, reversible)
   • Close Opera. Press Win+R, paste %APPDATA%\Opera Software\ and rename the "Opera Stable" folder to Opera Stable.old (or similar).
   • Start Opera — it will create a clean profile. Check if it still freezes.
   • Undo: close Opera and rename the folders back to restore your original profile.
   • Warning: If you haven’t exported bookmarks or aren’t signed into Opera Sync, back them up first (Bookmarks → Export bookmarks) before doing profile surgery.
3. Check Opera’s Task Manager and logs
   • Opera internal task manager: Shift+Esc to see which tab/extension uses CPU/memory.
   • Windows Event Viewer: Windows Logs → Application — look for errors around the time Opera froze (source: Application Error, svchost, or opera.exe). That helps identify crashes/hangs.

Reinstall / update (if steps above don’t help)

1. Update Opera & GPU drivers
   • In Opera: Settings → About Opera to force an update.
   • Update your GPU drivers from Device Manager or the GPU vendor (NVIDIA/AMD/Intel).
   • Why: driver incompatibilities often cause browser hangs.
2. Reinstall Opera (preserve bookmarks)
   • Export bookmarks first (Bookmarks → Export bookmarks), or sign in to Opera Sync.
   • Uninstall Opera (Control Panel → Apps), then reinstall the latest Opera from the official site.
   • After reinstall, import bookmarks if needed.

System-level checks (if browser still unstable)

1. Run system file checks (Windows)
   • Open an elevated Command Prompt (Admin) and run:
     sfc /scannow
     DISM /Online /Cleanup-Image /RestoreHealth
   • Why: fixes Windows file corruption that can affect apps.
2. Test in a new Windows user account
   • Create a new local user account and run Opera there. If Opera is fine in the new account, the issue is in your profile or user-specific settings.
3. Collect evidence if you need to escalate
   • Save Event Viewer entries (right-click → Save Selected Events) and note time stamps. If you want, post the specific error lines here (or attach the exported event file) and I’ll interpret them.
   • If Opera produces crash reports, note the time and any crash IDs in Opera’s About or Help → Report a Problem.

What I’d try first (my recommendation)

• Step 1 → Step 3 (disable extensions) → Step 4 (hardware acceleration) → Step 6 (fresh profile). These usually find or temporarily fix the majority of freezes.

If you try those and it’s still freezing, tell me:

• Results of steps you ran and which step changed behavior (if any).
• Any error messages from Event Viewer or Opera (copy/paste text).
• Which Opera version and Windows 11 build (Win+R → winver).

I can then give exact commands and, if needed, walk you through exporting logs and doing a clean reinstall safely.
