Error code 0Xc004F074 - What is it?
Did you previously use Windows 7 or 8 but decided to run with the latest Windows 0S, Windows 10? An early error message encountered was activation error code 0Xc004F074.

Solution
Error Causes
Various factors might incite error code 0Xc004F074. A primary cause is a discrepancy or difference between the KMS client and the KMS host machine. The host computer could possibly be operating a Windows Server 2003 or Windows Server 2008, while the client runs on OS Windows 7 or Windows Server 2008 R2. To supplement, the computer’s time might be a contributing factor. The time on the host machine and client might show a difference (Usually the host time exceeds 4 hours).
Further Information and Manual Repair
To rectify error code 0Xc004F074, users are advised to try various methods. These methods include:-
Method 1: Update Your KMS Host 9 (Windows Server 2003)
Are you running later versions of Windows Server? Use an update that fixes or installs KMS on your computer. The update is available on Microsoft’s website. Keep clearly in mind that the update is only for Windows Server 2013 Service Pack 1 and later versions of Windows Server 2003.

Method 2: Update Your KMS Host 9 (Windows Server 2008)

Method 3: Update the Time
It was previously mentioned that the time reflected on the KMS host and client might cause error code 0Xc004F074 to manifest. A simple fix to adhere to is to always ensure that the time between both is updated. To Resync the time on the client, execute the following command.

Method 4: Uninstall the Existing KMS
For this method to be successfully deployed, you’ll need to have in your possession an activation key or KMSpico Key. As you cannot apply the new key with the existing one, remove or uninstall the initial key. To perform this step, open the command prompt. This should be done while the computer is in admin mode. Then, run the command
(slmgr.vbs /dlv)
It should be executed without the brackets and before you have removed the existing key.
After executing the command, you’ll encounter the description:
Windows(R) Operating System, VOLUME_KMS_WS12_R2 channel
Move along with the process by applying the slmgr.vbs /upk to uninstall the existing KMS key.
After the old key is uninstalled, you’re ready to apply the following:
slmgr.vbs /ipk <NewKMSProductKey>
To check if things are in place and complete the process, follow the steps below: PC Settings >Update and Security > Activation

If you have a driver device error inside Windows, you should see it immediately when entering the Device Manager, it will have a yellow exclamation mark beside it. Right-click on it and choose update driver.
Microsoft has released Windows 11 as a public beta release for all the people that are not willing to be in the insider program.
Beta release as of this moment is identical to Insider Preview build 22000.100. and updates will not roll so fast as in insider preview and it is marked as unstable release, same as insider build.
I would not install Windows 11 beta on the main PC since some drivers still have issues and may lead to some blue screens.
Be aware that the beta build will have all Windows 11 system requirements including TPM 2.0. This is a big difference from insider build which can be installed on systems lacking official requirements.
So basically if you have a spare PC that could run Windows 11 install it so you can see what it brings and feel it so you can make a decision will upgrade once it is released later this year.
