'Keep my files' removes installed applications and reverts settings to defaults while leaving documents, pictures, and other personal files in place.
2. When chkdsk is run on the active system drive (C:) while Windows is running, what happens?
Because the system volume is locked by Windows when in use, chkdsk schedules the scan to run before Windows loads on the next restart.
3. A drive shows as 'RAW' in Disk Management after a power failure. What is the most likely cause?
A RAW file system status means Windows cannot recognize or read the file system, usually due to corruption.

Protection history in the Virus & threat protection section shows a log of all detected threats and the actions taken.
5. Which Windows 10 feature runs Microsoft Edge in an isolated Hyper-V container to contain browser-based attacks?
Application Guard launches Edge in a hardware-isolated Hyper-V container so malicious websites cannot access the host OS.
