Error Code 0xc004c008 - What is it?
This specific Windows 8.1 or Windows 10 error code has to do with the number of times you can use your license number to install windows programs on computers. All windows activation codes are licensed to be used one time for a device, to control piracy, but what happens when your PC crashes, or you have to change a hard drive component and are forced to re-install Windows Operating System. Luckily, there is an easy fix for this issue.
Solution
Error Causes
Basically, when you need to re-install the Windows operating system that you have previously bought and installed on another computer an error code will be displayed with a message telling you that the activation server determined that the specific key could not be used for activation. This occurs because the key has already been used on that computer, or a different one, to install operating systems. There are a few easy fixes for this issue, and most of them should be easily completed on your own.
Further Information and Manual Repair
There aren’t many explanatory ways to repair Error Code 0xc004c008. Below are two methods to go about addressing this issue.
Methods 1:
- The first step is to open the “Run” Window. You can do this in two ways. First, press the “Window” key and press the “R” key simultaneously. This will open the “Run” menu. Or you can start the “run” window by going to the Start menu and selecting Run.
- In the Run window type “SLUI 4” and click enter.
- A Phone Activation window will open up, after which you'll need to select a few options.
- First chose the country in which you registered the product for the first time.
- Choose your country and a phone number will be displayed specific to your choice. You will now need to call the number provided.
- After you’ve dialed you will be prompted to write your “Installation ID”. Type your “Installation ID” on the phone.
- After that step, you will be asked how many copies of Windows have been installed using this license. Choose “1”, should anything else be chosen but “1”, this will not work.
- After the process is completed, you will be given a confirmation ID and should be able to proceed as normal with installation. You will have a workable product key again.
- Install whatever copy of the Windows Operating System you are attempting to with the new product key.
Method 2:
If the first method did not work, the only other option is to call Microsoft and walk through the process with a technician. To do this, dial “1-800-936-5700”. Explain the error that you received and the steps in the update process during which it was displayed.

If we are to believe news from Intel, new series of processors based on Alder Lake architecture are about to be released somewhere in October. Alder Lake is the 12th Generation Core of Intel processors and it is meant to have all advantages of the current CPU structure.
I9 is aimed to pack a punch against its competitors with technology including eight high-performance Golden Cove cores (P-cores) with Hyper-Threading and eight energy-efficient Goldmont (E-cores) equipped with a 30MB L3 cache and operating at high clock speeds.
During the benchmark test, the new CPU outperformed all of Intel’s previous Rocket Lake structure processors which is logically expected but the big surprise came from results that indicate better performance than Apple’s new M1 processor even in single-threaded performance which is supposed to be best in that field.
Another surprise was really beating AMD Ryzen 9 in each field. If we take into account that i9 has 16 cores in total and can process 24 threads against Ryzen 9 with 16 Cores and 32 threads this is an impressive feature.
Now truth to be told Alder lake has massive L3 cache and microarchitectural advantages and consumes much more power but the results of performance are high. Also, note that this early CPU is not really a mass production one and maybe some things will still change but early results are very satisfactory.
We will see what will price tag be since in this age of shortage and competition that will also play a big role in its overall success. Speaking of competition I eagerly await AMD’s response to this, in any way it seems that the CPU market is for some turbulence which is always a good thing for the final customer and I welcome it.
