Registerymanager (Advanced Windows Registry Manager)

A Windows-only Registry Manager written in Python, with a CustomTkinter GUI for browsing, editing, backing up, and applying “preset” tweaks to common Windows settings.

⚠️ Warning: Editing the Windows Registry can break apps or the OS. Always backup before changing values, and prefer operating under HKEY_CURRENT_USER (HKCU) unless you know exactly what you’re doing.

What it does

• Browse registry keys (Tree view) under HKEY_CURRENT_USER
• Read / create / edit / delete registry values
• Value filtering (search within the current key by name/value/type)
• Favorites (persisted to favorites.json)
• Presets (persisted to presets.json) for common Windows UI toggles
• Backups / Restore using reg.exe export / reg.exe import (saved to backups/)
• Change history in memory with Undo / Redo stacks (not persisted)

Features (detail)

1) Registry Browser

• Tree navigation (lazy-load of subkeys).
• Value panel shows: Name / Type / Value.
• Actions:
  • Edit an existing value
  • Delete a value
  • Create a new value (supports REG_SZ, REG_DWORD, REG_QWORD, REG_BINARY)
  • Filter values by substring match
  • Backup key to .reg

2) Presets (built-in)

The app ships with default presets that modify common HKCU settings, including:

• Enable / Disable Dark Mode
• Show / Hide File Extensions
• Show / Hide Hidden Files
• Enable / Disable Title Bar Color

Presets are stored in presets.json and can be extended by adding new entries with:

• a target path (subkey)
• a list of values as (name, data, type) triples

3) Favorites

Save frequently used key paths into favorites.json. Each entry includes:

• hive name (string, e.g. "HKEY_CURRENT_USER")
• key path
• optional label

4) Backups + Restore

Backups are created via Windows’ built-in tooling:

• reg export <key> <file> /y
• reg import <file>

Backups are timestamped and stored under backups/.

5) History + Undo/Redo

Registry write/delete operations can be recorded into an in-memory history:

• Undo stack / redo stack (bounded deque)
• Undo/redo replays changes by restoring old values or reapplying the new ones
