Hello,
The issue you're experiencing—where taskbar icons appear as generic placeholders until hovered over—may be related to a temporary delay in Windows loading application resources or a corrupted icon cache.
To resolve this, we recommend the following steps:
Restart Windows Explorer by pressing Ctrl + Shift + Esc, locating Windows Explorer in Task Manager, right-clicking it, and selecting Restart.
Rebuild the icon cache by running the following command in Command Prompt (as administrator): ie4uinit.exe -show
Ensure your system is fully updated via Settings > Windows Update.
If the issue persists, consider performing a clean boot to rule out third-party software conflicts.
