🔍 How do you check disk health (HDD/SSD)?

The hard drive is where all your data is stored. A disk failure means data loss.

1. Click Start and type CMD, open it as "Run as Administrator".
2. Type the following command and press Enter:
chkdsk c: /f
3. The computer will ask whether to run the check on the next startup - type Y and restart.

Why is this important? The command scans for bad sectors and fixes file system errors before they turn into a full crash.

Recommended timing: before installing new software

🛡️ Creating a Restore Point (System Restore)

A restore point is a "time machine." If you installed software that broke your computer, you can go back in time to when everything worked.

1. Search the taskbar for: "Create a restore point".
2. In the window that opens, make sure protection for drive C is On.
3. Click the Create button and give the point a name (e.g. "Before installing Office").

Importance: recovering accidentally deleted/edited files

📄 "Previous Versions" (File History)

Accidentally deleted an important paragraph in a Word document and saved it? You can go back.

1. Right-click a folder or file.
2. Select Restore previous versions.
3. If the feature is enabled, you'll see a list of dates for previous versions of the file.

How do you make sure it's working? Look in File History settings and connect an external drive or network server for ongoing file backup.
