573If your terminal reports `'claude' is not recognized` right after Claude Code updated on Windows, check whether `%USERPROFILE%\.local\bin` still contains `claude.exe`. If that directory isn't on your PATH at all, see [Fix your PATH](#command-not-found-claude-after-installation) instead. To update on Windows, Claude Code renames the existing `claude.exe` aside to a backup and moves the new version into its place. If moving the new version into place fails and Claude Code can't rename the backup back either, the directory keeps the backup but has no `claude.exe`.
574 
575The backup is a file in the same directory whose name begins with `claude.exe.old.` followed by a numeric timestamp. Run the following in PowerShell to rename the newest backup back to `claude.exe`:
576 
577```powershell theme={null}
578Get-ChildItem "$env:USERPROFILE\.local\bin\claude.exe.old.*" | Sort-Object Name | Select-Object -Last 1 | Rename-Item -NewName claude.exe
579```
580 
581Then run `claude --version` to confirm the fix. A restored `claude.exe` prints a version number.
582 
583If there's no `claude.exe.old.*` file, or `claude` still fails after the rename, reinstall instead:
584 
585```powershell theme={null}
586irm https://claude.ai/install.ps1 | iex
587```
588 
589Before v2.1.281, Claude Code could delete the backup while `claude.exe` was still missing.
