| **Repair** | `DISM` | Run DISM /Online /Cleanup-Image /RestoreHealth |
| | `SFC` | Run SFC /scannow (System File Checker) |
| **Optimization** | `OptimizeDisk` | TRIM for SSD, Defrag for HDD |
| | `DiskCleanup` | Windows Disk Cleanup (temp files, updates) |

| **Time/Date** | `SetTimezone` | Set timezone to Eastern Standard Time |
| | `SyncTime` | Force time sync with domain controller |

**Usage:**
```powershell
# Run DISM on a single PC
.\Invoke-RemoteMaintenance.ps1 -ComputerName "G1ZTNCX3ESF" -Task DISM

# Optimize disks on multiple PCs
.\Invoke-RemoteMaintenance.ps1 -ComputerName "PC01","PC02" -Task OptimizeDisk

# Run disk cleanup on all shopfloor PCs
.\Invoke-RemoteMaintenance.ps1 -All -Task DiskCleanup

# Clear Windows Update cache (fixes stuck updates)
.\Invoke-RemoteMaintenance.ps1 -ComputerName "PC01" -Task ClearUpdateCache
```

**Parameters:**
| Parameter | Default | Description |
|-----------|---------|-------------|
| `-ComputerName` | - | Single or multiple computer names/IPs |
| `-ComputerListFile` | - | Path to text file with computer list |
| `-All` | - | Target all shopfloor PCs from ShopDB |

**What it does:**
1. Establishes WinRM connections to target PCs
2. Executes `Update-PC-CompleteAsset.ps1` remotely
3. Collects and logs results from each PC
4. Supports parallel execution for efficiency

**Usage:**
```powershell
# From file with prompted credentials
.\Invoke-RemoteAssetCollection.ps1 -ComputerListFile ".\shopfloor-pcs.txt"

# Specific computers with stored credentials
$cred = Get-Credential
.\Invoke-RemoteAssetCollection.ps1 -ComputerList @("PC001","PC002") -Credential $cred

# Test connections only
.\Invoke-RemoteAssetCollection.ps1 -ComputerList @("PC001") -TestConnections
```

# With domain suffix
.\Invoke-RemoteAssetCollection-HTTPS.ps1 -HostnameList @("PC001","PC002") -Domain "logon.ds.ge.com"

# From file
.\Invoke-RemoteAssetCollection-HTTPS.ps1 -HostnameListFile ".\hostnames.txt" -Domain "logon.ds.ge.com"

# Test HTTPS connections
.\Invoke-RemoteAssetCollection-HTTPS.ps1 -HostnameList @("PC001") -Domain "logon.ds.ge.com" -TestConnections
```

**Parameters:**
| Parameter | Default | Description |
|-----------|---------|-------------|
| `-HostnameList` | - | Array of hostnames (without domain) |
| `-HostnameListFile` | - | Path to text file with hostnames |

3. Collects system info remotely and POSTs to API
4. Logs success/failure for each PC

**Usage:**
```powershell
# Update all shopfloor PCs from ShopDB database
.\Update-ShopfloorPCs-Remote.ps1 -All

# Update specific PCs
.\Update-ShopfloorPCs-Remote.ps1 -ComputerName "PC001","PC002"

# Setup WinRM trusted hosts first
.\Update-ShopfloorPCs-Remote.ps1 -SetupTrustedHosts
```

## WinRM Setup

### On Management Server:
```powershell
Enable-PSRemoting -Force
Set-Item WSMan:\localhost\Client\TrustedHosts -Value "*" -Force
```

### On Target PCs:
```powershell
Enable-PSRemoting -Force
Set-NetFirewallRule -DisplayName "Windows Remote Management (HTTP-In)" -Enabled True
```

For HTTPS setup, see the `winrm-https/` folder documentation.
