Gab*_* R. 146 windows screensaver security-policy
我们的公司 BOFH 强加了屏幕锁定设置,但延迟时间短得可笑。这是令人沮丧和适得其反的。
有没有办法防止自动锁屏?我认为没有办法覆盖策略强制设置,但也许有一个模仿用户活动的软件。
在我设置永久鼠标滚轮之前问一下。(得到它?)

如果仍安装了 Windows Media Player,您可以循环播放视频并将其最小化(示例“Wildlife”视频对此很有效)。默认情况下,只要正在播放视频,屏幕就不会锁定。

我使用了一个名为 idle.vbs 的脚本:
Dim objResult
Set objShell = WScript.CreateObject("WScript.Shell")
Do While True
objResult = objShell.sendkeys("{NUMLOCK}{NUMLOCK}")
Wscript.Sleep (6000)
Loop

每六秒,这会快速切换键盘上的 numlock,使 Windows 相信有人正在与键盘交互,从而防止屏幕锁定。这在 vanilla windows 上运行,您不需要开发或脚本工具来使用它,只需制作一个以 .vbs 作为扩展名的文本文件,然后双击它(或将它放在您的启动项中)。
编辑:您可以将此脚本放在您的启动项中
choco install IdleVbs -source https://www.myget.org/F/joshrivers-utility/

另一种选择是免费软件Caffeine程序。它也可免费用于商业用途。从程序的主页:
如果您的 PC 锁定或进入睡眠状态有问题,咖啡因会使其保持清醒。它的工作原理是每 59 秒模拟一次按键操作,因此您的机器认为您仍在使用键盘,因此不会锁定屏幕或激活屏幕保护程序。
Caffeine 的工作原理是每 59 秒模拟一次 F15 键按下事件。在所有可用的按键中,F15 可能是干扰最少的(我从未见过带有该键的 PC 键盘!),并且最不可能干扰您的工作。
这种现成的解决方案还允许您控制何时启用和禁用它:
双击程序图标会清空咖啡壶,这就是图标所代表的,并暂时禁用程序。再次双击它会重新装满锅,并使您的机器保持清醒。

该工具使用SetThreadExecutionState WinApi 函数来保持屏幕打开。这是视频播放器用来在您观看电影时保持屏幕打开的功能。
我创建了一个类似于 PowerToys Awake 的小托盘图标应用程序CoffeeBean 。我的工具的优点是:
如果您了解 AutoHotkey 工具,则可以使用以下脚本。
扩展Cherona的答案,这里是 PowerShell 中使用 SetThreadExecutionState() 的实现。
只要脚本正在运行,屏幕保护程序和屏幕锁定就不会启动。

您可以创建一个AutoIt脚本来连续按下一个未使用的键(例如,让它切换数字锁定、滚动锁定)、休眠一分钟左右,然后重复。或者,如果你经常使用键盘,你可以让它在任何方向移动一个像素左右。
如果您不希望它持续运行,您还可以将脚本作为计划任务(如果您有访问权限)启动,以便在计算机处于非活动状态一段时间后启动。
如果您不想进入 AutoIt 语法,这是一个非常简单的脚本来执行不可见的鼠标移动:
While True
Local $pos = MouseGetPos()
MouseMove($pos[0]-1, $pos[1]-1, 0)
MouseMove($pos[0], $pos[1], 0)
Sleep(540000)
WEnd

此脚本将鼠标光标在左上方向移动一个像素,然后将其返回,然后休眠 9 分钟(540000毫秒)。当脚本运行时,您可以在托盘中看到 AutoIt 图标。您可以通过右键单击此图标并选择相应选项来停止它。
要制作脚本,请安装 AutoIt,右键单击任何文件夹并选择New> AutoIt v3 Script,命名它,右键单击这个新脚本,选择Edit,粘贴上面提供的代码并保存。您甚至可以将其编译为.exe(同样,从上下文菜单)以启动,例如,从 Windows 调度程序。
我喜欢使用简单和集成的选项(没有额外的软件),比如一个 powershell 脚本(感谢https://dmitrysotnikov.wordpress.com/2009/06/29/prevent-desktop-lock-or-screensaver-with-powershell/ ) 使用“f15”作为成功的关键(感谢咖啡因。它确实干扰最少)
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

将其放入 myScriptName.ps1 并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: 也许管理员进行了一些更改,但这对我不再适用现在我必须使用来自 NBirnel 的 autohotkey 脚本:https : //github.com/nbirnel/nosleep - 这个工作完美,因为它移动鼠标(不会分散任何工作的注意力)

有一个名为“Timeout Blocker”的安卓应用,它会每隔一段时间振动一次,你可以把鼠标放在上面。它说不要在工作中使用它。https://play.google.com/store/apps/details?id=com.isomerprogramming.application.timeoutblocker&hl=en
很多这些答案都是旧的,只有通过输入/鼠标移动才能保持活力。用 C 或 C++ 编译它,这将通过设置线程执行状态来保持会话处于活动状态(当然仅限 Windows)
