pgAdmin 4图标显示异常求助（Windows 10 x64）：卸载重装无效

I’ve run into similar wonky icon glitches on Windows before—super frustrating when everything works but you can’t make out the icons. Here are some practical, tested fixes to try:

• Reset the Windows Icon Cache
  Windows often gets confused with icon caches after repeated app installs/uninstalls or system updates. Resetting it usually clears up weird rendering issues:

  1. Open Task Manager with Ctrl+Shift+Esc, find and end the Windows Explorer process.
  2. Launch Command Prompt as Administrator, then run these commands one after another:

     taskkill /IM explorer.exe /F
     DEL /A /Q "%localappdata%\IconCache.db"
     DEL /A /Q "%localappdata%\Microsoft\Windows\Explorer\iconcache*"
     start explorer.exe
     

  3. Restart your PC to let the system rebuild the icon cache from scratch.

• Adjust High DPI Scaling for pgAdmin 4
  If you have a high-res display, Windows might be scaling pgAdmin’s icons incorrectly. Fix this:

  1. Right-click the pgAdmin 4 shortcut (or the executable in C:\Program Files\pgAdmin 4\vX\bin where X is your installed version) and select Properties.
  2. Switch to the Compatibility tab, check the box for Override high DPI scaling behavior.
  3. Pick Application from the dropdown menu, click OK, then restart pgAdmin.

• Repair the pgAdmin 4 Installation
  A full uninstall might leave behind leftover registry entries or broken files. Try repairing instead:

  1. Go to Settings > Apps > Apps & features, find pgAdmin 4 in the list.
  2. Click it, select Modify, then choose the Repair option in the installer.
  3. Follow the prompts to finish the repair, then launch the app again.

• Update Windows 10 to the Latest Build
  Outdated system files can cause compatibility hiccups with app icons. Head to Settings > Update & Security > Windows Update and install all pending updates (including optional ones). Reboot once updates are done.

Quick note: Since your pgAdmin functions work fine and icons are still clickable, this is almost certainly a system-side icon rendering or cache issue—not a bug in pgAdmin itself.
