Intune中使用Powershell禁用TLS1.0

Question

我想禁用TLS 1.0和其他折旧加密。所以我创建了这个powershell脚本，并把它放在所有服务设备刀片的脚本下面。

下面是我的剧本。

在这里输入图像描述

当我用我的测试组测试它时，一切都在工作。但是，我意识到当用户(谁有本地管理员)删除注册表项(例如，HKLM:\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.3\Client)时，它不会重新创建键(因此脚本似乎只运行了一次？--即使在我尝试同步帐户之后)。如何做到这样，即使用户删除注册表项，脚本也会周期性地运行并重新创建注册表项？

建议您使用您的脚本作为一个积极的补救对的一半，这样脚本可以触发重新运行，如果有人扰乱设置。
