CPU Not Compatible – What Is It

Some users wanting to upgrade to Windows 10 from Windows 7 or Windows 8.1 experienced errors with installation. One of these errors is CPU Not Compatible. When you click and run the “Get Windows 10” from your system tray bar, you’ll receive the “CPU is not compatible with Windows 10” error. When this happens, it might be good to check if there’s a bug or if your NX feature (a requirement for the Windows 10 installation) is enabled.

Solution

Error Causes

The “CPU is not compatible with Windows 10” error normally occurs when:

• NX feature is not enabled
• You experienced the Windows 10 bug

Further Information and Manual Repair

To successfully upgrade to Windows 10, your CPU must support Physical Address Extension (PAE), SSE2, and NX features. If any of these features are not activated on your system, it’ll cause the CPU not compatible error. However, some users still reported experiencing this error even though their CPU has these features activated. Normally, this is due to the bug that Windows acknowledged.

If any of these two scenarios apply to your computer, the following methods will help you fix the problem:

Method 1 – Check for bugs

The bug applies to some Windows 7 and Windows 8.1 systems. The bug occurs when the “Get Windows 10” app fails to recognize CPUs as being compatible. This produces a false negative result with a message, “Here’s why Windows 10 cannot be installed on this PC: The CPU isn’t supported”. To fix this bug, Microsoft released an update.

Unfortunately, the patch update (KB2976978 for Windows 8/8.1 and KB2952664 for Windows 7 SP1) to fix the bug may not be automatically downloaded to your computer. If this is the case, you need to verify first if the patch was installed correctly. To do this, follow the steps below:

1. Click ‘Start’ and type in View Installed Updates. The “View installed updates” icon should appear. Click the icon.

2. Go to the Search bar (Top right portion) then type the patch name for your system. Make sure that you type the correct patch name for your system since Windows 7 and Windows 8/8.1 have different names. If you find the patch, it means it’s already installed. You can now upgrade to Windows 10 without the CPU not-compatible error.

3. But, if you can’t find it you need to install the patch manually.

4. Go to Windows Update then click the “Check for Updates” button.

5. Browse through the available updates and look for KB2976978 for Windows 8/8.1 or KB2952664 for Windows 7 SP1

6. Download the right patch. You may need to reboot your system once it’s done.

7. The downloaded patch should be applied after a day or two with the Windows Task Scheduler. Once the patch is applied, you can now upgrade to Windows 10.

Method 2 – Check CPU features and activate them if needed

A major requirement for Windows 10 upgrade is for the CPU to have Physical Address Extension (PAE), SSE2, and NX features enabled on your system. If you receive the CPU not compatible error, one possible cause is that any of the mentioned features are not available OR not enabled on your system. Here’s how you can fix this:

1. Verify if your CPU supports the three instruction sets. You can use software that provides information like this. If all three are available, proceed to the next step.

2. Go to your computer’s BIOS. To do this, reboot your computer. You will need to press a key specific to your computer’s manufacturer (usually it’s F12, F8, F2, or DEL).

3. Look for the NX (No Execute Bit) settings. This is normally found in the “Advanced Configuration” menu, or something similar to this. Just take note that the NX setting can be named differently in BIOS. Some other names include EDB (Execute Disabled Bit), EVP (Enhanced Virus Protection), Execute Disabled Memory Protection or No Excuse Memory Protect.

4. Once you’re in the NX settings, make sure that it’s enabled.

5. Exit the BIOS and SAVE your changes.

6. Boot your computer normally, then try upgrading to Windows 10 again through the “Get Windows 10” app found in the system tray.

Method 3 – Force enabling NX Bit

If changing the settings in your BIOS doesn’t do the trick, your final option is to force enable the NX bit in your Windows system. However, this is only applicable IF and ONLY IF your CPU does support it. To force enable NX bit, do the following:

1. Click Start and go to command prompt (Type “cmd” – no quotes) and press enter.

2. Copy and paste the text below to the command prompt.bcdedit.exe /set {current} nx AlwaysOn

3. Execute the command. You will need to reboot your computer once this is done.

4. Download and install Windows 10

Method 4 – Use a trusted automated tool

If you still experience the error after doing the methods above, you might want to try a powerful and trusted automated tool to fix the job.

Referenced Memory at - What is it?

0x Referenced Memory at 0x is an error code that occurs when the random memory addresses conflict. This error causes running programs or browsers to crash. Referenced memory at error code is considered as a service violation error. It is displayed as the following:

“The instruction at 0xf77041d24 referenced memory at 0×00000000. The memory could not be read.”

Solution

Error Causes

The ‘referenced memory at’ errors is either triggered by:

• Hardware failure
• Problems with the RAM and the registry

Hardware failure may result if the driver is not installed properly. The problems in the RAM indicate registry issues that occur due to data overload in the hard disk and poor PC maintenance. The registry saves all the information and activities you perform on your system on the hard disk. This includes the junk files, temporary files, invalid registry entries, and files of both installed and uninstalled programs.  These files accumulate and take over a lot of RAM space. Also, the referenced memory at error can be considered to be a form of memory leak where unknown third-party software can take up the memory space that has been reserved for a particular program. For example, if you have toolbars and add-ons installed in your browser, it can also lead to invalid registry storage in the registry. If you don’t clean the registry, these unnecessary files can overload your data and lead to hard disk/RAM damage and corruption triggering obscure error messages like referenced memory at error.

Further Information and Manual Repair

Referenced memory is a critical error; if not resolved it can lead to serious PC damages like a system failure. To avoid this, it is advisable to fix it right away. Here are a couple of ways to repair this issue on your system:

Cause: Hardware Failure

Solution: If the referenced memory at error is generated due to hardware failure then to resolve this error you must reinstall the driver that has caused the error to appear. Let’s say if the error pops up because of the printer driver, reinstall it. For re-installation of the driver, simply go to the control panel and click on the Device Manager option. Once you click it you will see a detailed page with a list of devices. Now click on the printer (the problematic driver in this situation) to reinstall the driver software. Double click on it to open the properties dialog box and then click the driver tab and update the driver. Once you have updated the driver, try using the printer. Check if it works. If it works and the referenced memory at the error code does not appear on the screen, this means the problem was with the hardware. However, if the error still pops up then this means the problem is deeper. It’s related to the registry.

Cause: Problems with the RAM and the registry

Solution: If the problem is with the RAM and the registry, then it is advisable to download Restoro. Restoro is a new, next-generation, and highly functional registry cleaner.

Option 2 – Try to reset the Catroot2 folder

You can also try resetting the catroort2 folder as it is known to fix tons of Windows Update issues including the Windows Update error code 0x80d02002. Both the Catroot and catroot2 are Windows operating system folders that are required for the Windows update process.  So when you run the Windows Update, the catroort2 folders stores the signatures of the Windows Update package and helps it in the installation. It makes use of the “%windir%System32catroot2edb.log” file in the updating process. Afterward, the updates are stored in the SoftwareDistribution folder which is used then by the Automatic Updates in order to execute the updating process. Keep in mind that you must not rename or delete the Catroot folder. Although the Catroot2 folder is recreated automatically by Windows, the Catroot folder isn’t.

Option 3 – Try running the DISM tool to fix the broken Windows Update client

The Windows update/upgrade error 0x80d02002 might be caused by some issues in the Windows Update client so you need to run the DISM tool to repair it. Note that you have to use another computer or another Windows from a shared network to fix it.

Option 4 – Try to run the Windows Update Troubleshooter

Running the built-in Windows Update troubleshooter could also help you resolve the Windows Update error 0x80d02002. To run it, go to Settings and then select Troubleshoot from the options. From there, click on Windows Update and then click the “Run the troubleshooter” button.

Option 5 – Try to run Microsoft’s troubleshooter online

You also have the option to run Microsoft’s online troubleshooter which could help you fix Windows Update errors.

A copy of Windows gets into a grace period when it is installed on a computer which means that you can use your Windows computer without any constraints on its feature. However, if you suddenly encounter an error code 0xC004F009 then this means that the grace period has already expired. In such cases, you will see the following error message on your screen:

“Error Code 0xC004F009, The Software Licensing Service reported that the grace period expired.”

One of the possible causes of this error is that it could be that the grace period has already expired way before the system was activated which is a result of which the system is in the Notifications state at this moment. The error code 0xC004F009 has something to do with MAK-enabled computers in an enterprise when it comes to Volume Licensing. One of the reasons that this error pops up is due to the possibility that the computer was not activated yet even when it was already connected to the Enterprise. Another most likely cause of the error is when the system was never connected with the Enterprise at all and the given grace period has expired before your computer system is activated. Whatever the real cause of this error, this post will guide you in fixing it. Just refer to the instructions given below to fix it.

Option 1 – Try activating Windows using the command-line tool

• First, you need to obtain your MAK key from the IT administrator.
• Once you have it, tap the Win + R keys on your keyboard and then type “cmd” in the field and hit Enter to open an elevated Command Prompt.
• After that, type this command and hit Enter to install the product key or replace the existing one: Slmgr.vbs –ipk <your mak key>
• Next, type another command and hit Enter: slmgr.vbs –ato
• Once you’ve executed the given commands, Windows should be activated after it connects to Microsoft servers and then gives it some time and try to check if error code 0xC004F009 is now fixed or not.

Option 2 – Try activating Windows using your mobile phone

Activating Windows 10 can also be done using your phone. Just note that you have to call Microsoft to do so.

• In the Start Search box, type in “Slui 4” and tap Enter.
• Next, select your country and click on Next.
• Keep the window open and call the toll-free number of the country you’re from.
• Afterward, a confirmation ID should be given by the automated system which you must take a note of.
• Finally, in the box on the window, type in the confirmation ID and click on the Activate button. That should do it.

Option 3 – Try to prolong the grace period

On the other hand, it is also possible for you to prolong the grace period but you might have to get another genuine Windows key for that. Before you proceed, you need to create a System Restore point first afterwards, refer to the steps given below to increase the grace period of the Software Licensing Service on your Windows 10 computer.

• Tap the Win + R keys to open the Run dialog box and type “Regedit” in the field then hit Enter to open the Registry Editor.
• After that, navigate to this registry key: HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionSetupOOBEmediabootinstall
• Next, change the value of the “mediabootinstall” key to “0”.
• Now open Command Prompt with admin privileges and then type this command and hit Enter: slmgr –rearm
• The command you just entered will add another grace period to your system activation. After that, you have to obtain a new key and then activate Windows.

Option 4 – Try running the Windows 10 Activation Troubleshooter

You can also try to run the Windows 10 Activation troubleshooter to help resolve the error code 0xC004F009.

• Go to Settings and then select Activation.
• After that, click on the Windows Activation and then troubleshoot. This will help you address most of the commonly found activation issues in Windows devices.
