################################################################################ <# .SYNOPSIS Marks files or directories for deletion during the next system boot. .DESCRIPTION This function uses the Windows API to mark files for deletion on next boot. It handles locked files by first attempting to rename them to temporary names and tracks all moves to maintain file system integrity. If renaming fails, the -MarkInPlace parameter can be used to mark files in their original location. .PARAMETER Path One or more file or directory paths to mark for deletion. Accepts pipeline input. .PARAMETER MarkInPlace If specified, marks files for deletion in their original location when renaming fails. This is useful for locked files that cannot be renamed. .EXAMPLE Remove-OnReboot -Path "C:\temp\locked-file.txt" .EXAMPLE "file1.txt","file2.txt" | Remove-OnReboot -MarkInPlace #> function Remove-OnReboot { [CmdletBinding(SupportsShouldProcess)] [OutputType([bool])] param( ############################################################################### [Parameter( Mandatory = $true, Position = 0, ValueFromPipeline = $true, HelpMessage = "Path(s) to files/directories to mark for deletion" )] [ValidateNotNullOrEmpty()] [Alias("FullName")] [string[]]$Path, ############################################################################### [Parameter( Mandatory = $false, HelpMessage = "Marks files for deletion without renaming" )] [switch]$MarkInPlace ############################################################################### ) begin { # registry location storing pending file operations $regKey = "HKLM:\SYSTEM\CurrentControlSet\Control\Session Manager" $regName = "PendingFileRenameOperations" # get existing pending renames or initialize empty array try { $pendingRenames = @(Get-ItemProperty -Path $regKey ` -Name $regName -ErrorAction SilentlyContinue).$regName } catch { $pendingRenames = @() } if ($null -eq $pendingRenames) { $pendingRenames = @() } } process { try { foreach ($item in $Path) { $fullPath = GenXdev.FileSystem\Expand-Path $item if (Test-Path -LiteralPath $fullPath) { if ($PSCmdlet.ShouldProcess($fullPath, "Mark for deletion on reboot")) { try { # attempt immediate deletion first Remove-Item -LiteralPath $fullPath -Force -ErrorAction Stop Write-Verbose "Successfully deleted: $fullPath" continue } catch { Write-Verbose "Direct deletion failed, attempting rename..." try { # create hidden temporary file name $newName = "." + [System.Guid]::NewGuid().ToString() $newPath = [System.IO.Path]::Combine($dir, $newName) # rename and hide the file Rename-Item -Path $fullPath -NewName $newName -Force ` -ErrorAction Stop $file = Get-Item -LiteralPath $newPath -Force $file.Attributes = $file.Attributes -bor ` [System.IO.FileAttributes]::Hidden -bor ` [System.IO.FileAttributes]::System Write-Verbose "Renamed to hidden system file: $newPath" # add to pending renames with windows api path format $sourcePath = "\??\" + $newPath $pendingRenames += $sourcePath $pendingRenames += "" Write-Verbose "Marked for deletion on reboot: $newPath" } catch { if ($MarkInPlace) { Write-Verbose "Marking original file for deletion" $sourcePath = "\??\" + $fullPath $pendingRenames += $sourcePath $pendingRenames += "" } else { Write-Error "Failed to rename $($fullPath): $_" continue } } } } } else { Write-Warning "Path not found: $fullPath" } } if ($pendingRenames.Count -gt 0) { # save pending operations to registry Set-ItemProperty -Path $regKey -Name $regName ` -Value $pendingRenames -Type MultiString return $true } } catch { Write-Error "Failed to set pending file operations: $_" return $false } return $true } end { } } ################################################################################ |
