“artigo retirado do AVG Official Blogs”
por Sandro Villinger



No dia 17 de outubro, a Microsoft lançou sua atualização drástica para o Windows ® 8 – a nova versão 8.1 vem com atualizações muito cobiçadas, como o retorno do botão Iniciar, uma interface do Windows Store atualizada, uma integração mais profunda com o  SkyDriveTM e uma interface moderna atualizada.


Se você tem o Windows 8 ou 8.1, a atualização mais recente da AVG para o  popular expository essay ghostwriter site nyc inclui um novo mecanismo de limpeza para o Windows Store e para aplicativos do Windows 8.


Dados inúteis ocultos nos aplicativos do Windows 8/8.1


Ao navegar no novo Windows Store ou baixar e usar aplicativos, dados inúteis são coletados e em muitos casos ficam na sua máquina. Estes dados temporários incluem arquivos de log, imagens, cookies, listas de histórico e arquivos de metadados que são mantidos dentro de uma pasta oculta no Windows 8 e 8.1. Assim como acontece com qualquer navegador, o aplicativo Windows Store e seus aplicativos do Windows 8 precisam de uma limpeza regular por duas razões importantes:


* Você vai economizar espaço em disco: Dependendo de quanto eles usam o Windows Store e seus aplicativos, os usuários muitas vezes podem se livrar de centenas de megabytes de dados.


* Você resolve problemas: Limpar a loja e os aplicativos pode ajudar a resolver problemas ao iniciar ou usar o Windows Store e seus aplicativos.


Veja como fazer isso:


Todos os usuários do AVG PC TuneUp ( pay to get custom dissertation results) receberão a atualização automaticamente e gratuitamente. Se essa atualização não aparecer, veja o que você precisa fazer:


1. Vá em “Ajuda & Suporte” e clique em “Verificar se há atualizações”.


2. Depois de um momento, a nova atualização deve aparecer e atualizar o seu Disk Cleaner. Para verificar se há dados inúteis no Windows Store e nos aplicativos, vá para a categoria de “Limpar” e abra “Organizar Windows e programas.”


3. Em seguida, habilite a categoria “Caches” e pressione o botão Limpar.



4. Para ver o que está dentro, clique duas vezes em “Caches” e veja quais arquivos foram encontrados em “aplicativos do Windows Store”:

Como você pode ver em um exemplo nesta máquina com Windows 8.1 instalado no início de setembro, encontrei mais de 28.000 (!) arquivos temporários. Eles foram:


– arquivos MP3 e vídeos: Por exemplo, arquivos que foram temporariamente armazenados por aplicativos do YouTube® ou outros clientes de streaming


– Downloads: Arquivos que foram baixados através do aplicativo Google Chrome™ ou Internet Explorer®, por exemplo.


– Flash clips: animações em Flash ou clips (.flv) que foram incorporados em algumas aplicações e, portanto, baixado no PC


– Cookies & Arquivos Temporários: Muitos aplicativos usam cookies para armazenar informações para reconhecê-lo, da mesma maneira como um navegador faz. Além disso, aplicativos como o Xbox ® Music Marketplace usa um navegador padrão (por exemplo, Internet Explorer) para exibir o conteúdo. Isso resulta em arquivos temporários de navegação sendo armazenado em seu disco rígido sempre que você usar esses aplicativos.


Aceite o desafio – baixe e teste isso hoje mesmo e deixe-nos saber o quanto você foi capaz de limpar? Estamos ansiosos para ouvir suas experiências!
