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。
我使用了一个脚本,我把它命名为idle.vbs:
Dim objResult
Set objShell = WScript.CreateObject("WScript.Shell")
Do While True
objResult = objShell.sendkeys("{NUMLOCK}{NUMLOCK}")
Wscript.Sleep (6000)
Loop
choco install IdleVbs -source https://www.myget.org/F/joshrivers-utility/
每隔6秒,这个脚本就会快速切换键盘上的numlock,使Windows认为有人在与键盘交互,防止屏幕锁定。这可以在vanilla windows上运行,你不需要开发或脚本工具就可以使用它,只需制作一个以.vbs为扩展名的文本文件,然后双击它(或将它放在启动项中)。
编辑:你可以将这个脚本放在你的启动项中,用

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)。
在我的案例中,只需将其放在Timer_Tick
事件中,并将时间间隔设置为60000ms。
你应该关闭 “屏幕锁定”/“睡眠模式",从控制面板>电源选项>更改计划设置。点击下拉菜单中的 "让电脑进入睡眠模式 "并选择 "从不"。
