Until ($TimeNow -ge $TimeEnd)

it prompts every 2 hours for 6 hours. The highlighted 360 is for the over all length and 7200 is the time (in seconds) between prompts.

执行该脚本的显示效果：单击提示信息时，会显示另外一个提示框，点Yes时，会重启电脑；选择No时，每隔两小时会再次提醒。该提示信息只显示5秒，因为Windows系统设置默认只显示5秒。

但是关闭PowerShell ISE时，该提示图标就自动退出了。

解决方法：将上面的脚本保存为NotifyReboo.ps1, 然后新建bat脚本test.bat,内容如下：

@ECHO OFF
if "%1"=="hide" goto CmdBegin
start mshta vbscript:createobject("wscript.shell").run("""%~0"" hide",0)(window.close)&&exit
:CmdBegin

SET CurrentPath=%~dp0

powershell.exe -sta -executionpolicy bypass -file  "%CurrentPath%RebootNotify.ps1"

Exit

也就是用test.bat脚本去调用NotifyReboot.ps1,然后在后台运行。　　

SET CurrentPath=%~dp0 这里是设置当前路径。需要把两个脚本放在同一个目录 下。然后，运行test.bat即可以看到上面的提示效果。
