How do I clean registry in windows 11 after uninstalling apps?

Cleaning leftover registry entries after uninstalling programs can improve system stability and prevent context menu or error issues. Here's a comprehensive guide to clean registry for Windows 11 safely and effectively.

1. Built-in Windows 11 Tools
sfc /scannow and DISM:
   * These tools are primarily for repairing system files and images, not for cleaning leftover registry entries.
   * They won't specifically remove leftover registry remnants of uninstalled programs.
   * Use them if you suspect system file corruption, but they won't target leftover app entries.

2. Manual Registry Cleanup
Using Registry Editor (regedit.exe) to clean registry for Windows 11:
Caution: Manual editing can cause system instability if done incorrectly.
Best practices:
Backup your registry first:

• Open Registry Editor (Win + R, type regedit, Enter).
• Click File > Export and save a backup.

Identify remnants:
Common places include:

•  HKEY_CURRENT_USER\Software\
•  HKEY_LOCAL_MACHINE\SOFTWARE\
•  HKEY_CLASSES_ROOT\

Look for keys or entries related to the uninstalled program.
Search carefully:

• Use Edit > Find (Ctrl + F) to locate program-specific entries.
  Delete with caution:
• Only delete entries you are certain are leftover from the uninstalled program.
