#Define helper function that generates and saves screenshot
Function Get-Screenshot {
   $ScreenBounds = [Windows.Forms.SystemInformation]::VirtualScreen
   $ScreenshotObject = New-Object Drawing.Bitmap $ScreenBounds.Width, $ScreenBounds.Height
   $DrawingGraphics = [Drawing.Graphics]::FromImage($ScreenshotObject)
   $DrawingGraphics.CopyFromScreen( $ScreenBounds.Location, [Drawing.Point]::Empty, $ScreenBounds.Size)
   $DrawingGraphics.Dispose()
   $ScreenshotObject.Save($FilePath)
   $ScreenshotObject.Dispose()
 }

2、将截屏图片按时间命令并按路径存储

Try {
        #load required assembly
        Add-Type -Assembly System.Windows.Forms            
        Do {
            #get the current time and build the filename from it
            $Time = (Get-Date)
            [String] $FileName = "$($Time.Month)"
            $FileName += '-'
            $FileName += "$($Time.Day)" 
            $FileName += '-'
            $FileName += "$($Time.Year)"
            $FileName += '-'
            $FileName += "$($Time.Hour)"
            $FileName += '-'
            $FileName += "$($Time.Minute)"
            $FileName += '-'
            $FileName += "$($Time.Second)"
            $FileName += '.png'
            #use join-path to add path to filename
            [String] $FilePath = (Join-Path $Path $FileName)
            #run screenshot function
            Get-Screenshot
            Write-Verbose "Saved screenshot to $FilePath. Sleeping for $Interval seconds"
            Start-Sleep -Seconds $Interval
        }
        #note that this will run once regardless if the specified time as passed
        While ((Get-Date -Format HH:mm) -lt $EndTime)
    }

3、脚本执行方法

#执行命令Get-TimedScreenshot#path：指定存储路径#Interval：截屏时间间隔，单位 秒#EndTime：脚本停止时间，如果不设置，会一直执行

PS C:\> Get-TimedScreenshot -Path C:\监控截屏 -Interval 1 -EndTime 19:00

记录一举一动：PowerShell几行代码实现定期屏幕截屏

监控电脑屏幕？

实现思路

1、通过windows脚本，一定时间间隔进行屏幕抓拍

2、脚本通过powershell语言实现

3、powershell为windows系统自带语言，可以无缝嵌入运行

4、所有抓拍的屏幕照片，按照时间排序，可以实现比较完整的用户操作监控。
