5]使用云重置

使用云重置选项^{(Cloud Reset option)}，看看是否有帮助。

6]使用安装媒体^{(Installation Media)}修复Windows 10^{(Repair Windows 10)}

最后但同样重要的是，如果没有任何效果，请尝试使用安装介质修复 Windows 10^{( repairing Windows 10 using Installation Media)}。这不会删除您的任何个人文件，并且会为您解决问题。

希望您能够在这些解决方案的帮助下解决PowerShell问题。^(PowerShell)

You can use any third-party application to scan your computer but we are going to use Windows Defender. So, if you want to use Windows Defender to scan your computer for viruses and malware, try the following procedure.
