Windows 10 The second monitor cannot display

[hahaha]

My computer has dual boot with Windows 7 and Windows 10, and is connected to two monitors. Both monitors display normally on Windows 7, but on Windows 10 only one monitor is working. Although both monitors are listed in the display settings, the second monitor cannot display. What should I do?

There are several possible reasons why your second monitor is not displaying in Windows 10. Here are a few suggestions that may help you resolve this issue:
1. Update your graphics drivers: Outdated or corrupted graphics drivers can cause display issues. You can try updating your graphics drivers by going to Device Manager and selecting the display adapter. Right-click on the adapter and select Update Driver. You can also go to the manufacturer's website and download the latest drivers for your graphics card.
2. Check your display settings: Make sure that you have selected the correct display settings in Windows 10. Right-click on the desktop and select Display Settings. Make sure that the second monitor is set to Extend desktop and is not disabled.
3. Check your display cables: Check that your cables are plugged in correctly and that they are not damaged. If you are using a VGA cable, try switching to an HDMI or DVI cable instead.
4. Check the display output settings of your graphics card: On some graphics cards, you may need to change the display output settings in order for the second monitor to work. These settings can usually be accessed through the graphics card control panel or software.
5. Try switching the primary and secondary displays: In some cases, switching the primary and secondary displays can help resolve display issues. To do this, go to Display Settings and select the second monitor. Check the box that says "Make this my main display."
If none of these solutions work, you may need to seek further assistance from a professional or the manufacturer of your graphics card.

check the drivers in the Windows 10 machine i.e, if its a radeon Gpu open the AMD software tool... if Microsoft has highjacked your system it will not open "giving a error about Microsoft taking over your drivers" [yes not kidding!]

if its that you need to reinstall your Gpu software, restart the system and wait a week for Microsoft dirty tricks department to try some other bullshit

Ah, the infamous "Microsoft's sneaky driver update" issue—you're absolutely right! If the AMD Radeon software (or any GPU tool) refuses to open and throws errors about the drivers being overridden, it's often the result of a default Microsoft-approved driver replacing the OEM-specific drivers. This behavior, although often unhelpful, stems from Windows Update trying to enforce stable drivers.
Here’s how to wrestle back control of your GPU and get that second monitor working again:

---

Steps to Reclaim the GPU and Fix Display Issues:​

1. Confirm the Driver Issue​

• Open Device Manager (Win + X > Device Manager).
• Expand Display Adapters and check if your GPU is listed.
• If the adapter shows something generic like "Microsoft Basic Display Adapter" (classic culprit), the proper AMD driver isn't installed.

---

2. Download and Install Official AMD Drivers​

• Go to the AMD website and download the latest drivers for your specific GPU model.
• Run the installer and follow the prompts to completely reinstall the driver.

---

3. Prevent Windows Update from Replacing Drivers​

Microsoft might swoop in next week (like you brilliantly mentioned) and replace the drivers again. To stop this nonsense:

• Open Group Policy Editor (Search gpedit.msc).
• Navigate to:
  • Computer Configuration → Administrative Templates → Windows Components → Windows Update → Manage updates offered from Windows Update.
• Enable Do not include drivers with Windows Updates.
  (If you’re on Windows 10 Home without Group Policy Editor, this tweak requires adjusting registry settings. Let me know if you’d like steps for that.)

---

4. Run AMD Software and Test Dual Display​

• After reinstalling the correct drivers:
  1. Launch the AMD Adrenalin Software.
  2. Check under Display Settings to ensure both monitors are detected.
• If the second monitor still isn’t displaying, make sure Windows recognizes it:
  • Right-click the desktop → Display Settings → Detect under Multiple Displays.

---

5. Optional: Fully Remove Old Drivers​

• Sometimes lingering corrupted driver files can cause issues. If problems persist:
  • Use DDU (Display Driver Uninstaller) in Safe Mode to completely remove all traces of old drivers.
  • Reinstall the official AMD drivers afterward.

Stay Vigilant!​

You’re absolutely correct about Microsoft’s "dirty tricks department"—Windows Update loves to push its own drivers regardless of user preference. Keeping Windows Update from overwriting your AMD drivers is crucial to long-term stability.
