Windows Fixer 🔧

One-Click Windows System Repair & Health Check Utility

Windows Fixer is a powerful yet safe PowerShell script that automates common Windows troubleshooting tasks. It features an interactive menu system for easy navigation, fixes system corruption, cleans junk files, checks your disk health, and generates a beautiful, easy-to-read report—all with a single click. No technical knowledge required!

✨ New in Version 2.0

🎨 Interactive Menu System - Beautiful visual interface with no command-line knowledge needed
💻 Real-Time System Status - View CPU, RAM, GPU, disk space, and uptime at startup
🔍 Quick Health Check Mode - Fast 5-minute scan without time-consuming repairs
🗑️ Cleanup-Only Mode - Free up disk space without running full repairs
📊 Quick Report Access - Instantly view your last scan results
🎯 Smart Post-Execution Menu - Choose what to do after repairs complete
🔄 Auto-Cleanup - Automatically removes reports older than 7 days

What Does Windows Fixer Do?

Windows Fixer performs these operations automatically:

Feature	What It Fixes	Time Required
Quick Health Check	Read-only system scan	5 minutes
SFC Scan	Corrupt system files	15-30 minutes
DISM Repair	Broken Windows image	20-40 minutes
Disk Health Check	Failing hard drive/SSD	1 minute
Temp File Cleanup	Junk files taking up space	2-5 minutes
Memory Test	Detect bad RAM modules	Requires reboot
Registry Fixes	WMI, Windows Update, Network issues	5-10 minutes (optional)

🛡️ Safety First

Windows Fixer is designed to be safer than manual repairs:

✅ Creates restore points before making changes
✅ Backs up registry automatically
✅ Uses only Microsoft-approved commands
✅ Opt-in for registry changes — will not touch registry unless you ask

Prerequisites

What you need:

Windows 10 or Windows 11 (64-bit)
Administrator access to your computer
At least 5 GB of free space on C: drive
Internet connection (recommended for DISM repair)

Installation (3 Steps)

Step 1: Download the Script

Download WindowsFixer.ps1 from the GitHub repository:

Click the green "Code" button → "Download ZIP"
Extract the ZIP file to your Desktop

Result: You should see the Windows-Fixer folder on your Desktop with WindowsFixer.ps1 inside the src folder.

Step 2: Allow PowerShell Scripts (One-Time Setup)

Windows blocks scripts by default for security. Let's allow this one:

Right-click the Start button → Select "Windows PowerShell (Admin)" or "Windows Terminal (Admin)"

Copy this command:

Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser -Force

Right-click in the PowerShell window to paste, then press Enter

What this does: Allows you to run local scripts like Windows Fixer while still blocking malicious ones from the internet.

How to Use Windows Fixer

� Simple Method (Recommended)

Navigate to Desktop\Windows-Fixer\src\ (or OneDrive\Desktop\Windows-Fixer\src\ if using OneDrive)
Right-click WindowsFixer.ps1
Select "Run with PowerShell"
Click "Yes" when User Account Control asks for administrator permission
The interactive menu will appear automatically

That's it! No shortcuts, no command-line knowledge needed. Just right-click and run.

🎨 Interactive Menu Mode

Once you run the script, you'll see a clean menu with real-time system information:

Understanding Your Report

After running Windows Fixer, you'll see an HTML report with comprehensive results:

Executive Summary

At the top, you'll see a quick checklist:

✅ Green = Good/Was Fixed
⚠️ Yellow = Warning/Attention Needed
❌ Red = Error/Requires Manual Action

Key Sections Explained

0. System Information (New!)

OS version, build, and uptime
Last scan timestamp
System specifications

1. Preflight Checks

Pending Reboot: If "True," restart needed before fixes work properly
Free Space: Should be >10 GB. Low space causes wonky behavior

2. SFC Scans (System File Checker)

Shows if corrupt Windows files were found and repaired. Run twice for thoroughness. Note: Skipped in Quick Health Check mode.

3. DISM Restore Health

Repairs the Windows image itself. If this fails, you may need installation media. Note: Skipped in Quick Health Check mode.

4. Disk Health Analysis

WMIC Status: Should say "OK" for all drives
SMART Details: If "Predict Failure" is True, backup immediately—drive is dying

5. Critical Events

Lists recent system errors. More than 10 in 7 days indicates deeper issues.

6. Cleanup Summary

Shows how many GB of junk files were removed.

7. Registry Repairs (If Enabled)

Shows what registry fixes were applied. Always creates restore point first.

8. Registry Health Scan (Read-Only)

Lists orphaned apps and startup programs. Review before manually deleting.

Menu Options Explained

🔍 Quick Health Check (Option 1)

Duration: ~5 minutes
What it does:

✅ System status check
✅ Disk health + SMART data
✅ Event log analysis
✅ Registry health scan (read-only)
✅ Temp file cleanup
❌ Skips SFC/DISM (saves 35-70 minutes)

Use when: You want to check if there are issues without waiting for long repairs.

🛠️ Standard Repair (Option 2)

Duration: ~30-45 minutes
What it does:

✅ Everything from Quick Health Check
✅ SFC scan (2 passes)
✅ DISM image repair
✅ DISM component cleanup
❌ No registry modifications

Use when: Windows feels broken, or you have update/corruption issues.

What it does:

Launches Windows Memory Diagnostic tool
Prompts you to restart manually to run the test
Tests RAM for defects and errors

Use when: You suspect RAM issues (random crashes, blue screens, system instability).

Note: The tool will open and ask you to restart. You can also use the post-execution menu's "Reboot Now" option after viewing your report.

🗑️ Cleanup Only (Option 5)

Duration: ~2-5 minutes
What it does:

✅ Removes temp files (User + System + CBS logs)
✅ DISM component cleanup

File Locations

Reports & Logs

All files are saved to:

C:\Users\YourName\OneDrive\Documents\WindowsFixer\

or (if OneDrive is disabled):

C:\Users\YourName\Documents\WindowsFixer\

Files created:

WindowsFixer_Report_[timestamp].html - Detailed HTML report
WindowsFixer_Log_[timestamp].txt - PowerShell transcript log
RegistryBackup_[timestamp]\ - Registry backups (only with Full Repair)

Automatic Cleanup:
Files older than 7 days are automatically deleted on each run to save disk space.

Troubleshooting

Problem: "Script cannot be loaded because running scripts is disabled"

Solution: Run Step 2 again (Command: Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser -Force).

Problem: "Access denied" or "Administrator rights required"

Solution: Make sure you right-click the script and select "Run with PowerShell". Windows will automatically prompt for administrator permission (UAC). Click "Yes" when prompted.

Problem: Script window appears briefly then disappears

Solution: The script detected it wasn't running as administrator and tried to restart elevated. Make sure you're using the right-click method described above. If the issue persists, temporarily add -NoExit flag to test (see Power Users section).

Problem: Menu doesn't appear, script runs directly

Solution: You're using command-line flags. Remove -SkipMenu, -IncludeRegistryFixes, and -AutoMemoryTest parameters to see the interactive menu.

Problem: DISM fails with "Error: 0x800f081f"

Solution: You need Windows installation media for repair. This is rare and indicates deep system damage. Contact support or consider a clean Windows reinstall.

Problem: Report doesn't open automatically

Solution: Find it manually in your Documents folder:

Documents\WindowsFixer\WindowsFixer_Report_[date]_[time].html

Or use Menu Option [6] to quickly open the last report.

Problem: System seems slower after running

Solution: This is normal for the first 5-10 minutes. Windows is rebuilding indexes and caches. Restart if it persists beyond that.

Frequently Asked Questions

Q: Is this safe? Will I lose my files?

A: Yes, it's safe! Windows Fixer only repairs system components and cleans temporary files. Your documents, photos, and programs are never touched.

Q: How often should I run this?

A: Run it when your system feels "wonky"—slowdowns, glitches, or weird errors. As preventive maintenance, once per month is fine. Use Quick Health Check for regular check-ups.

Q: Can I use my computer while it runs?

A: Light use (web browsing) is okay, but avoid heavy tasks like gaming or video editing. The script needs full system access.

Q: What if something goes wrong?

A: Windows Fixer creates a system restore point before changes. To undo:

Press Win + R → Type rstrui → Press Enter
Select the restore point named "Windows Fixer - Registry Repairs"
Follow the wizard to restore

Q: Do old reports get cleaned up automatically?

A: Yes! Version 2.0 automatically deletes reports older than 7 days to save disk space. You always keep the last week of history.

Q: Does this work with OneDrive?

A: Yes! Version 2.0 automatically detects OneDrive Documents folder and saves reports there if OneDrive is enabled.

Q: Do I need to pay for this?

A: No! Windows Fixer is completely free and open-source.

Q: Will this work on Windows 7/8?

A: No. Windows Fixer is designed for Windows 10 and 11 only.

Uninstalling / Cleanup

Windows Fixer doesn't install anything, so removal is simple:

Delete the Windows-Fixer folder from your Desktop (or OneDrive\Desktop)
Delete the Documents\WindowsFixer or OneDrive\Documents\WindowsFixer folder (contains reports and logs)

(Optional) Revert the execution policy:

Set-ExecutionPolicy -ExecutionPolicy Restricted -Scope CurrentUser -Force

That's it! No registry entries, no system files modified.
