Determina o tamanho do registro

Question

Como posso determinar o tamanho do meu registro?

Estou tentando fazer backup do meu registro, e está demorando muito.

Eu não acho que havia um caminho de arquivo que eu poderia ir para verificar suas propriedades como qualquer outro arquivo? Como posso determinar seu tamanho?

    

Answer 1

%windir%\System32\config e %USERPROFILE%\NTUSER.DAT . A pasta config será ocultada, mas contém todas as seções do Registro, EXCETO para o HKEY_CURRENT_USER, que é o arquivo NTUSER.DAT

    

Answer 2

Para obter o tamanho do banco de dados do Registro, você pode consultar o WMI A classe Win32_Registry em Powershell, script completo aqui .

$data=Get-WmiObject -Class Win32_Registry -ErrorAction Stop
#Format the results and write an object to the pipeline 
$data | Select-Object -Property @{Name="Computername";Expression={$_.__SERVER}},
Status,
@{Name="Current Size (Mb)";Expression={$_.CurrentSize}},
@{Name="Max Size (Mb)";Expression={$_.MaximumSize}},
@{Name="Free Size (Mb)";Expression={$_.MaximumSize - $_.CurrentSize}},
@{Name="Percent Free (%)";Expression={ (1 - ($_.CurrentSize/$_.MaximumSize))*100 }},
@{Name="Created";Expression={$_.ConvertToDateTime($_.InstallDate)}},
@{Name="Age";Expression={(Get-Date) - ( $_.ConvertToDateTime($_.InstallDate)) }}

Há também o utilitário dureg :

O download na descrição acima está errado, mas você pode google dureg e encontrar o executável. Por exemplo: link

Se você puder programar um pouco, consulte o link .

Copiar:
