Windows 10: Windows Activation Troubles: Troubleshoot and Change Product Key not working

I purchased an Acer Aspire E 14 E5-473-555Y a couple years ago with windows 10. However, it's been saying that windows is not activated for a while now. At first the activation error code displayed was 0xC004F074 but it recently changed to 0x8007007B. Troubleshooting says that it cannot activate windows and that I should ensure I am connected to the internet. When I re-enter the product key it says that windows cannot connect to my organization's activation server.


Can someone provide some assistance?

Windows 8.1 pro + WMC key activation

This worked for me last time with a Win 8 key.

Install Windows 8.1 and enter KMS key during setup. Once in windows change product key to my Windows 8 key. Go to add features and enter my WMC add-on key. Drink a beer to a job well done.

If you're having trouble activating Windows 10, follow these steps to fix activation errors:

2. Use the Activation troubleshooter to resolve simple errors. For more info, see Try the Activation troubleshooter below.

3. If you're still getting an error, check the list of error codes below and follow the suggested steps to resolve it.

Make sure the error hasn't changed. Sometimes when you run the Activation troubleshooter or try to activate, the error code and message will change. If the error code has changed, look up the new code below and follow the recommended steps. (If you're getting
