去年我实现了一个 SW，它可以根据 SW 状态改变电源按钮操作。SW 通过更改注册表项来实现这一点
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Power\PowerSettings\7648EFA3-DD9C-4E3E-B566-50F929386280\ACSettingIndex
并执行 gpupdate.exe。当时它运行正常。但一年后我收到一个错误报告，声称它不再起作用。但我的 SW 仍然以相同的方式工作（更改注册表值并更新 gpupdate）。我尝试通过手动更改注册表值并调用 gpudate 来重现问题，但得到的结果相同。调用 gpresult 显示，该值与我在注册表中设置的值不同。但是，当我更改注册表值并重新启动计算机时，将应用更改的值。
gpresult 的输出：
C:\windows\system32>gpresult /R /V
