Microsoft PowerToys Not Working? Common Errors & Fixes

When Alt+Space does nothing, PowerToys usually isn't running, the Run module is off, or an elevated window or another tool is grabbing the shortcut. Re-enable Run, try the centralized keyboard hook, or restart PowerToys as admin.

If windows don't snap into zones, check that FancyZones is enabled and 'Hold Shift to activate zones' is set the way you expect, restart PowerToys as admin for elevated windows, and toggle FancyZones off and on after reboot or update.

Keyboard Manager only works while PowerToys runs and the module is enabled, and it can't touch admin windows unless PowerToys is elevated. App-specific remaps must use the process name (msedge.exe, not 'Microsoft Edge').

PowerToys keeps helper processes for several utilities running so they open instantly, which adds up on 8 GB machines. Turn off unused modules, run only one launcher, and update to pick up memory-leak fixes.

Windows blocks a normal app from intercepting keys or moving windows of an elevated app, so PowerToys must also run as administrator. Use 'Restart as administrator' from the General tab when PowerToys shows the elevated-app notification.

Text Extractor (Win+Shift+T) only reads languages with a Windows OCR pack installed. Install the pack via PowerShell, set it as the Preferred language, and copy the OCR folder to C: if Windows is on another drive.

If PCs won't pair or get stuck between Negotiation and Connecting, update both machines to PowerToys 0.102.3101 or newer (it fixed pairing and untrusted-signature errors), keep them on the same network, and add IP mappings.

If the Settings window won't open or is blank, quit PowerToys from the tray, start it again, then update to the latest release. A clean reinstall fixes most broken installs left by failed updates.

Major releases sometimes break modules (0.97.0 crashes, 0.102 File Locksmith/Quick Accent/Mouse Without Borders bugs). Install the follow-up hotfix, re-check that modules are still enabled, and restart.

AltGr is sent as Left Ctrl + Right Alt, so remapping Ctrl or Alt in Keyboard Manager breaks AltGr characters on non-US layouts. Remove remaps on Ctrl/Alt or target only one side.
