Primeiro, tente reinicializar para ver se isso limpa a interface do usuário. Se isso não acontecer, remova-os no Centro de backup e restauração:
Choose Start→Control Panel. Under the System and Security heading, click the Back Up Your Computer link.
The Windows 7 Backup and Restore Center appears.
Click the Change Settings link.
The Backup and Restore Center shows you a full analysis of the space occupied by your data backups and system image (“ghost”) backups.
Shadow copies/previous versions aren’t listed here because they’re stuffed into each drive’s system restore area.
Click the View Backups button.
The Backup and Restore Center shows you a list of all backups that have taken place recently, noting the size of the backup.
If you want to delete a backup, click it once and then click Delete.
Look for the really old, really big backups. Don’t worry — you’re only deleting the backup, not the original data. Click Close and then click X to close the Backup and Restore Center.
