Microsoft PowerToys

Microsoft's own free, open-source toolbox, and the single install that fixes the most small irritations at once. Command Palette is a fast keyboard launcher for apps, commands and tools; FancyZones snaps windows into layouts far beyond Windows' built-in snapping; PowerRename does bulk renames with regex and undo. The less obvious modules earn their keep too. File Locksmith tells you which process is holding a file you cannot delete, Text Extractor copies text from anything on screen, and Keyboard Manager remaps keys without registry hacks. Switch off the modules you will never use and the rest stays quiet in the tray. New releases arrive every couple of months, so expect the settings page to keep growing.
