找密码
|

|
|
||||||
|
解决方法：
|
||||||
|
|
||||||
|
click事件开头一堆垃圾，兜兜转转还是输入值，再往下一看发现是和系统盘序列号做比较（正确密码需要反转的十六进制分区序列号）
|
||||||
|
|
||||||
|
下面是生成正确serial的powershell命令
|
||||||
|
|
||||||
|
```powershell
|
||||||
|
"{0:X}" -f [convert]::ToInt32((Get-WmiObject Win32_LogicalDisk | Where-Object { $_.DeviceID -eq "C:" }).VolumeSerialNumber, 16) -split '' -join '' | % {$_[-1..-($_.Length)] -join ''}
|
||||||
|
```
