Hi everyone,
This is Bryan from the Office team. We are extremely sorry to learn that some of you are running into an issue with Office after upgrading from Windows 7 to Windows 10 where some of your Word, Excel and PowerPoint documents are failing to open with various error messages, such as:
- Word: “Word experienced an error trying to open the file”
- Excel: “This file is corrupt and cannot be opened”
- PowerPoint:
- “The application was unable to start correctly"
- “PowerPoint found a problem with <filename>"
- “Sorry, PowerPoint can’t read <filename>"
We are actively working on a fix to resolve this issue, but in the meantime, if you are running into this issues the following workaround should help unblock you:

This issue is encountered when a document is opened in Protected View. Protected View is a security feature in Office that opens potentially untrusted files in a secure sandbox where users can read them without fear of the file taking over their computer. You may have seen a number of posts that recommend solutions to disable or bypass Protected View to prevent this issue. We strongly discourage you from following these suggestions as it reduces the security of Office and leaves your computer open to attack from malicious users.
Once the workaround is completed, files which were previously causing this issue, should now open in Protected View allowing you to read them first within a secure sandbox and allow you to enable editing if you trust these files and need to work with them further.
We apologize for the inconvenience caused due to this issue!
Sincerely,
Bryan
