# User Profile Cleanup Script Readme

## Overview
This PowerShell script automates the process of identifying and removing inactive or unused user profiles on a Windows computer. It is designed to help maintain system performance by eliminating unnecessary files associated with old or unused accounts.

## Features

- **Identifies Inactive Profiles:** The script calculates the number of days since the last login or profile use and compares it against a specified threshold (`$InactiveDays`).
- **Exclusion List:** Certain user accounts can be excluded from deletion based on predefined criteria.
- **Error Handling:** Robust error handling ensures that issues during profile cleanup are reported, preventing potential data loss or system instability.
- **High Impact Operations:** The script is configured to run with high impact operations, ensuring it operates with the necessary privileges.

## Prerequisites

1. **Administrator Privileges:** The script must be executed with administrator privileges due to its high impact operations.
2. **PowerShell Environment:** Requires a PowerShell environment on Windows capable of running CIM cmdlets.
3. **Local User Profiles:** Works best when dealing with local user profiles, though it can handle domain accounts as well.

## How to Use

### Step 1: Save the Script
Download or copy the script into a `.ps1` file.

### Step 2: Review and Modify Settings
Before execution:
- **Excluded User Names:** Adjust the `$ExcludedUserNames` array to include any user accounts you wish to protect from deletion. This can include wildcard patterns (e.g., `"Example*"`).
- **Inactive Days Threshold:** Set `$InactiveDays` to determine how many days of inactivity are required before a profile is eligible for deletion.

### Step 3: Execute the Script
Run PowerShell as an administrator and execute the script:

```powershell
.\UserProfileCleanup.ps1
```

If you get a policy error about not being able to execute the script copy and run the contents of [ExecutionPolicy](/scripts/ExecutionPolicy.md)
