Solved Answer

However, some users may encounter a specific error, namely 0xe0000002, which is accompanied by the message “The exception unknown software exception.” This problem usually shows up when users open OneNote, which can cause interruptions like work loss or even unexpected application failures when the error notice displays.

Without more thorough diagnostic data, identifying the precise source of the problem can be difficult because it is an unknown software exception. This problem is frequently reported by users when they first launch OneNote, and in certain cases, it causes the program to crash without warning.

Fixing this issue is essential to getting OneNote back to normal and guaranteeing a smooth note-taking experience. Users can investigate alternatives including verifying for program conflicts, updating or reinstalling OneNote, and looking at system compatibility problems, however, precise solutions may differ based on the underlying cause.

Don’t pay ransomware authors – use alternative data recovery options

Malware attacks, particularly ransomware, are by far the biggest danger to your pictures, videos, work, or school files. Since cybercriminals use a robust encryption algorithm to lock data, it can no longer be used until a ransom in bitcoin is paid. Instead of paying hackers, you should first try to use alternative recovery methods that could help you to retrieve at least some portion of the lost data. Otherwise, you could also lose your money, along with the files. One of the best tools that could restore at least some of the encrypted files –  Data Recovery Pro.
