Win10下所有exe触发Bad Image错误及WiFi无法检测修复求助

Hey there, let’s work through this annoying Windows 10 issue together. It sounds like the dual-boot setup (and subsequent BIOS changes) messed up critical system files or settings—even after removing Ubuntu. Let’s break down the fixes step by step:

You mentioned modifying BIOS settings per a dual-boot tutorial, which is likely part of the problem. Let’s revert or adjust those:

• Restart your Acer Aspire E15 and press F2 repeatedly to enter BIOS.
• Locate the Secure Boot option: Ensure it’s set to Enabled (many dual-boot guides have you disable this, but Windows relies on it for system integrity).
• Check Fast Boot: If it’s enabled, toggle it off, save changes (press F10), restart, then go back into BIOS and turn it on again. This can resolve hardware detection glitches like missing WiFi.
• Verify SATA Mode: Make sure it’s set to AHCI (not IDE)—Windows uses AHCI by default, switching this can break system file access.
• Save all changes (F10) and restart your PC to test if WiFi comes back and exe files open.

The 0xc000012f error points to damaged DLLs or system files. Since you can’t open even Task Manager, you’ll need a Windows 10 installation USB:

1. On another PC, create a Windows 10 installation USB using the Media Creation Tool.
2. Plug it into your Aspire E15, restart, and press F12 to boot from the USB.
3. On the installation screen, click Repair your computer → Troubleshoot → Advanced options → Command Prompt.
4. Run these commands one by one (wait for each to finish):
   • sfc /scannow (Scans and repairs corrupted system files)
   • If SFC fails, run DISM /Image:C:\ /Cleanup-Image /RestoreHealth /Source:D:\sources\install.wim (Replace D: with your USB drive’s letter, and C: with your Windows partition).
5. Restart your PC and check if you can open exe files now.

Since your system reset got stuck at 11%, an in-place upgrade is a safer way to restore Windows without losing your personal files and apps:

1. Boot from the Windows 10 installation USB again.
2. Click Install now → When prompted for a product key, select I don’t have a product key (Windows will auto-activate if it was previously activated).
3. Choose the same Windows 10 edition you’re running (e.g., Home/Pro).
4. On the "Choose what to keep" screen, select Keep personal files and apps.
5. Follow the prompts to complete the installation. This will refresh your Windows system files while preserving your data.

If the above steps fix the exe issue but WiFi is still gone:

• Open Device Manager (now that exe files work), expand Network adapters.
• Look for your WiFi adapter (it may have a yellow exclamation mark). Right-click it and select Uninstall device.
• Restart your PC—Windows will automatically reinstall the WiFi driver.
• If auto-reinstall fails, download the official WiFi driver for your Acer Aspire E15 model from the manufacturer’s website (use another PC to save it to a USB), then install it manually.
