The Attachment Manager in Windows helps protect your computer from unsafe attachments that you might receive with an e-mail message and from unsafe files that you might save from the Internet. If the Attachment Manager identifies an attachment that might be unsafe, it prevents you from opening the file or warns you before you open the file. In Windows, you might get a warning that Windows protected your PC. Attachment Manager classifies file types as high risk, medium risk, and low risk.:
High RiskIf the attachment is in the list of high-risk file types and is from the restricted zone, Windows blocks the user from accessing the file before accessing the file. Moderate RiskIf the attachment is in the list of Moderate Risk file types, Windows will not prompt the user before accessing the file, regardless of the file’s zone information. Low RiskIf the attachment is in the list of low-risk file types, Windows will not prompt the user before accessing the file, regardless of the file’s zone information.
If your computer is unnecessarily blocking useful files and slowing down your work, you can disable the blocking of files entirely.
