We're having a communication problem and it's probably my fault.
1. Using the media creation tool to create Windows 10 recovery media will still give you the problematic Intel Management Engine Interface driver 11.0.0.1146
2. If you go back to Windows 8.1, then you use the Windows 10 media creation tool to upgrade again, however, you select Upgrade this PC. When you upgrade from Windows 8.1 to Windows 10, Microsoft leaves your existing Windows 8.1 Intel MEI driver 9.5.24.1790 alone and your PC should work fine....shutdown fine....sleep fine.
3. Since your computer came pre-installed with Windows 8.1 and you already have a digital license for Windows 10, there's no need to enter a Windows key. The key will be automatically retrieved from the UEFI.
There's a couple more avenues that you can take.
1. Use your Windows 8.1 factory default recovery drive.
2. If you forgot to create a factory default Windows 8.1 recovery drive, you can order you recovery media from the Acer Store.

3. You can also install vanilla Windows 8.1.

If you upgrade to Windows 10 again, Do Not use Acer Care Center to install the Windows 10 Turbo Boost driver 11.0.0.1146. Do not download the Turbo Boost driver 11.0.0.1146 from Acer's website either. Do not use the Intel Management Engine interface driver 11.0.0.1146 either.
If you want a driver that works for Windows 10 for your Haswell-ULT version R3-471T, then use Intel Management Engine interface driver 11.0.0.1181, but you'll need a geek friend to help you locate and install that driver.
Edit: There's thousands and thousands of people with Acer, HP, Dell etc computers that are currently using the Windows 8.1 driver 9.5.24.1790 for their Haswell-ULT computer with Windows 10 as workaround for the shutdown/hang, sleeop/hang issue. Just do some googling.
Good luck.
