SCAN

SCAN is a Windows diagnostics tool for reset-readiness and repair blockers.
It runs targeted system checks and gives actionable findings with remediation hints.

Core Checks

• disk space, disk/event health, and NTFS-related risk signals
• SFC / DISM / CHKDSK / WinSxS pending state
• WinRE and reset-policy readiness
• reboot-required and servicing-state flags
• suspicious autoruns, services, tasks, and startup entries
• BCD, TrustedInstaller, BitLocker, Secure Boot, TPM, and update health

Requirements

• Windows 10 or Windows 11
• Python 3.10+
• Administrator privileges

Run From Source

Recommended launcher (auto-elevates + installs Python dependencies):

RUN.bat

Direct usage:

python -m pip install -r requirements.txt
python main.py

Flags:

python main.py --fast
python main.py --no-pause
python main.py --fast --no-pause

Output Files

SCAN writes logs to %TEMP%\reset_diag:

• full_log.txt - verbose command output
• problems.txt - findings only
• console_output.log - terminal transcript

Exit code behavior:

• 0 = no blockers detected
• 1 = one or more findings detected

Build EXE (PyInstaller)

Use an isolated environment for reproducible builds:

python -m venv .buildvenv
.\.buildvenv\Scripts\python -m pip install --upgrade pip
.\.buildvenv\Scripts\python -m pip install -r requirements.txt pyinstaller
.\.buildvenv\Scripts\python -m PyInstaller --noconfirm --clean --onefile --name SCAN --icon icon.ico main.py

Build output:

• dist\SCAN.exe
