如何防止Windows 7系统中的策略强制屏幕锁定？

我们公司的BOFH强加屏幕锁定设置，延迟时间短得令人发指。

有什么方法可以防止自动锁屏吗？我会认为没有办法推翻策略强制设置，但也许有一种软件可以模仿用户的活动。

只是在我设置永久鼠标滚轮之前问一下。(明白了吗？)

如果仍然安装了Windows Media Player，你可以循环播放视频，然后将其最小化（样本 “Wildlife "视频可以正常使用）。默认情况下，只要视频在播放，屏幕就不会锁定。

然而，另一个选择是免费软件Caffeine程序。它是免费的，也可以用于商业用途。从程序的主页上看：

如果你的电脑出现锁机或睡眠问题，咖啡因可以让你的电脑保持清醒。它的工作原理是每59秒模拟一次按键，让你的机器认为你还在键盘前工作，因此不会锁屏或激活屏保。在所有可用的按键中，F15可能是干扰性最小的（我从未见过PC键盘上有这个键！），也最不可能干扰到你的工作。再次双击它就会将咖啡壶重新装满，并且会让你的机器保持清醒。

你可以创建一个 AutoIt 脚本，让它不断地按下一个未使用的键（例如，让它切换数字锁、滚动锁），休眠一分钟左右，然后重复。或者，如果你经常使用键盘，你可以让它向任何方向移动鼠标一个像素左右。

如果你不想让它持续运行，你也可以将脚本作为一个预定任务（如果你有权限的话），在电脑不活动一段时间后启动。

这是一个非常简单的脚本，可以执行一个隐形鼠标移动，如果你不想进入AutoIt语法：

While True
   Local $pos = MouseGetPos()
   MouseMove($pos[0]-1, $pos[1]-1, 0)
   MouseMove($pos[0], $pos[1], 0)
   Sleep(540000)
WEnd

这个脚本将鼠标光标向左上方移动一个像素点，然后将其返回，然后休眠9分钟（540000毫秒）。脚本运行时，你可以在托盘中看到AutoIt图标。你可以右击这个图标并选择相应的选项来停止它。要制作一个脚本，请安装AutoIt，在任意文件夹中右击，选择New>AutoIt v3 Script，命名，右击这个新的脚本，选择Edit，粘贴上面提供的代码并保存。你甚至可以把它编译成.exe（同样，从上下文菜单中）来启动，例如，从Windows调度器中启动。

有一个叫 “超时阻止器 "的安卓应用，每隔一段时间就会震动，你可以把鼠标放在上面。但它说不要在工作时使用。 https://play.google.com/store/apps/details?id=com.isomerprogramming.application.timeoutblocker&hl=en

在Visual Studio或C# Express中编译并从命令提示符中运行（或双击它）。需要.NET 4.0或以上版本。它可以实现你要找的一切。

我喜欢使用简单的和集成的选项（不需要额外的软件），就像一个powershell脚本（感谢https://dmitrysotnikov.wordpress.com/2009/06/29/prevent-desktop-lock-or-screensaver-with-powershell/），用 “f15 "作为成功的关键（感谢咖啡因。它确实是干扰最少的）

param($minutes = 180)

write "... screen will be awake for $minutes"

 $myshell = New-Object -com "Wscript.Shell"

 for ($i = 0; $i -lt $minutes; $i++) {
 write "... screen will be awake for" ($minutes-$i)
 Start-Sleep -Seconds 60    
 $myshell.sendkeys("{F15}")
}

把这个放到myScriptName.ps1中，然后通过桌面快捷方式或命令行启动它：C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -nop "C:\Users\myUser\Desktop\myScriptName.ps1"

更新：可能是管理员的一些改变，但这对我来说已经不起作用了，现在我必须使用NBirnel的自动热键脚本。https://github.com/nbirnel/nosleep —-这个工作完美，因为它可以移动鼠标（不会分散任何工作的注意力）。
