my pc security

Question

can I get microsoft to check all of my pc security to make sure its up to date

Answer 1

Microsoft can help review your Windows security through the Get Help app, although no check can guarantee that a PC is completely secure.

Request help from Microsoft

1. Select Start, type Get Help, and open the app.
2. Sign in with your Microsoft account.
3. Enter Check my PC security or describe any warning you see.
4. Follow the prompts to submit a support request or reach a Microsoft support representative. ^1^

A verified Microsoft support agent may offer a remote session using Quick Assist. Only enter a Quick Assist security code when you initiated contact through Microsoft Support. ^2^

Check the PC yourself first

1. Install Windows updates
   • Open Start > Settings > Windows Update.
   • Select Check for updates.
   • Install all available security updates and restart when requested.
   • Return to Windows Update afterward and verify that it says You’re up to date. ^3^
2. Check Windows Security
   • Open Start, type Windows Security, and select it.
   • The home page should not show any red warning symbols.
   • Open Virus & threat protection > Manage settings and check that Real-time protection, Cloud-delivered protection, and Tamper protection are on.
   • Open Virus & threat protection > Protection updates > Check for updates.
3. Run a Full scan
   • Go to Windows Security > Virus & threat protection > Scan options.
   • Select Full scan, then Scan now. This checks every file and program and can take considerable time. ^4^
4. Run an Offline scan if you suspect an infection
   • Save your open work first.
   • Go to Windows Security > Virus & threat protection > Scan options.
   • Select Microsoft Defender Antivirus (offline scan) and start the scan.
   • The computer will restart, scan outside normal Windows, and restart again. View the result under Windows Security > Protection history. ^5^

Important if the PC uses Windows 10

Free Windows 10 security fixes ended on October 14, 2025. A Windows 10 computer still operates, but running antivirus alone does not replace operating-system security updates. Use PC Health Check to determine whether the computer can move to Windows 11; otherwise, ask Microsoft Support about the currently available supported options for that device. ^6^

Avoid unsolicited callers, pop-ups, or websites claiming to be Microsoft. Never permit remote access unless you contacted Microsoft yourself through Get Help.
