How to Resolve “We couldn’t update system reserved partition” Error in Windows 10 Installation

In case you don’t know, Windows 10 supports installation and use of a number of removable devices which includes plug and plays mouse, keyboard, and other USB-based devices. But this could actually pose a threat to the integrity of a computer system and thus, some organizations pose a restriction in using these kinds of devices. the restriction on these devices is also useful especially if you keep on leaving your computer idle and someone tries to mess it up by plugging in a removable device. In such situations, the restriction will defend the user against data theft. Thus, in this post, you will be guided on how you can prevent the installation of removable devices on your Windows 10 computer. There are two options that can help you in preventing the installation of any removable devices on your computer – you can either try to use the Registry Editor or use the Group Policy Editor instead. Follow whichever option you want to use the instructions given below but before you start, don’t forget to create a System Restore Point first.

Option 1 – Prevent installation of Removable Devices via Registry Editor

• Tap the Win + R keys to open the Run dialog box and type “Regedit” in the field and hit Enter to open the Registry Editor.
• Next, navigate to this registry path: HKEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftWindowsDeviceInstallRestrictions
• From there, look for a DWORD named “DenyRemovableDevices” and set its value to “0”. On the other hand, if you can’t find this DWORD, just simply create it and set its value to 0.
• Once done, exit the Registry Editor and reboot your PC to apply the changes made.

Option 2 – Prevent installation of Removable Devices via Group Policy Editor

Keep in mind that the Group Policy Editor is not available in the Home Edition of the Windows operating systems. Thus, if you are using one, just stick to the first option, otherwise, proceed to the following steps.

• Tap the Win + R keys to open the Run utility and type “gpedit.msc” and click OK or tap Enter to open the Group Policy Editor.
• After that, go to this policy setting: Computer ConfigurationAdministrative TemplatesSystemDevice InstallationDevice Installation Restrictions
• Next, look for the “Prevent installation of removable devices” entry and once you find it, set it as “Enabled”. From this window, you should see the following description of this policy setting:

“This policy setting allows you to prevent Windows from installing removable devices. A device is considered removable when the driver for the device to which it is connected indicates that the device is removable. For example, a Universal Serial Bus (USB) device is reported to be removable by the drivers for the USB hub to which the device is connected. This policy setting takes precedence over any other policy setting that allows Windows to install a device. If you enable this policy setting, Windows is prevented from installing removable devices and existing removable devices cannot have their drivers updated. If you enable this policy setting on a remote desktop server, the policy setting affects redirection of removable devices from a remote desktop client to the remote desktop server. If you disable or do not configure this policy setting, Windows can install and update device drivers for removable devices as allowed or prevented by other policy settings.”

• Then click the Apply and OK buttons to save the changes made.
• Now restart your computer to save the changes made. This should prevent the installation of any removable devices in your Windows 10 computer.

If you suddenly get a message telling you that “Your Windows license will expire soon, You need to activate Windows in Settings” on your Windows 10 computer but you know that your Windows 10 is already activated. Worry not for this post will help you get rid of that error message right away. Before you get started, make sure that you have the Windows product key with you. If you don’t, you can get it by running the following command in an elevated Command Prompt:

wmic path SoftwareLicensingService get OA3xOriginalProductKey

Take note of the product key and then proceed to the options given below.

Option 1 – Try activating Windows 10 again or use another product key

• If you’re sure that you have the correct product key, click the Go to the Settings button.
• After that, click the Activate button once again.
• If you have another license key, you can also use that as well, just simply click on the Change product key.
• Then enter the new product key and click on Activate. That should fix the problem, if it doesn’t, refer to the next option below.

Option 2 – Try to reset the licensing status

• Click the Start button and then type “cmd” in the Search box and then tap Ctrl + Shift + Enter to open an elevated Command Prompt.
• Next, type the “slmgr –rearm” and hit Enter to reset the licensing status.
• Restart your computer and check if the error is now gone or not.

Option 3 – Try uninstalling the product key and re-enter it once more.

• The first thing you have to do to uninstall the product key is to know the Activation ID of your Windows installation. To do so, open an elevated Command Prompt and type this command, and hit Enter – vbs /dlv
• After you enter the command, you should see the licensing status and Activation ID. And to get all the Activation IDs of all the installed Windows versions, key in this command and hit Enter – vbs /dlv all

Note: The “/dlv” parameter will give you the license information for the installed operating system.

• After you enter the second command, you should see a Windows Script Host window with all the Windows licensing and activation status. Take note of the Activation ID.
• Next, in the same elevated Command Prompt, type this command – slmgr /upk <Activation ID>

Note: In the third given command, “/upk” stands for “uninstall product key”. This parameter uninstalls the product key of the current Windows edition.

• Restart your PC. After that, your computer will be in an unlicensed state so you need to re-enter the product key again.

Option 4 – Try rebuilding the Tokens.dat file.

The issue might be caused by a corrupted Tokens.dat file. The Tokens.dat file is a digitally signed file that stores most of the Windows Activation files so if it is corrupted then no wonder you’re having activation issues. To rebuild the Tokens.dat file, refer to these steps:

• From the WinX Menu, open an elevated Command Prompt.
• After opening Command Prompt, you need to type each one of the following commands and after you type each command, hit Enter.
  • net stop sppsvc
  • cd %windir%ServiceProfilesLocalServiceAppDataLocalMicrosoftWSLicense
  • ren tokens.dat tokens.bar
  • net start sppsvc
  • exe %windir%system32slmgr.vbs /rilc
• Now restart your computer.

Option 5 – Try running the Windows 10 Activation Troubleshooter

• 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.

Option 6 – Try activating Windows 10 via 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.

Error Code 0xc004fc03 – What is it?

Error code 0xc004fc03 occurs when Windows users fail to activate their Windows operating system due to a networking problem. The error code’s common symptoms include the following:

• Inability to activate Windows 10 operating system
• Message box with error code 0xc004fc03

Solution

Error Causes

Error code 0xc004fc03 in Windows 10 usually occurs due to issues related to a Windows user’s network. Your computer may be having problems connecting to the Internet or your firewall may be blocking or interrupting your device’s ability to activate Windows 10. In some cases, users may simply need to wait a day or two to reattempt to activate their system using a valid product key, as there may be an issue with the Windows activation servers.  Failure to promptly fix this error code might result in other Windows 10 error messages, such as error code 0xc004f034.

Further Information and Manual Repair

To rectify the error code, Windows 10 users will need to perform manual repair procedures that fix the underlying problems causing error code 0xc004fc03. These procedures may include reconnecting to one’s network, checking your firewall settings, or activating your Windows operating system via phone. The manual repair methods are simple and do not require technical knowledge of the Windows operating system. If your attempts at manually repairing this error code fail, however, you may need to try a few other procedures.

Method One: Verify Internet Connection

To check your Internet connection, you’ll need to access the Network & Internet tab in Windows 10. Follow the instructions below to access this tab and fix Internet connectivity issues if they are preventing you from activating Windows on your machine.

• Step one: Click the Start button and select Settings
• Step two: Select Network & Internet
• Step three: Click the Status section of the Network & Internet tab

If your status shows that you are not connected to a network, you will need to fix your connection. Simply use the Network Troubleshooter to troubleshoot your connection. You will be able to activate your copy of Windows once your connectivity issues are resolved.

If, however, the problem persists and error code 0xc004fc03 occurs during the activation process, this simply means that the existence of the error code is not due to connectivity or networking problems. In such a case, move to the next manual repair method listed below and follow the exact instructions given.

Method Two: Check Firewall Settings

Windows Firewall protects your PC from hackers, worms, and other malicious programs. However, in some cases, it may result in error codes like error code 0xc004fc03. If your firewall is interfering with the Windows 10 activation, you’ll be able to rectify the problem by simply adjusting your settings. Follow the steps below to check – and adjust if necessary – your Windows Firewall settings.

• Step one: Click search bar and type firewall
• Step two: Select Windows Firewall
• Step three: Select Turn Windows Firewall on or off

In some cases, Windows users may not be able to adjust settings within the Windows Firewall tab, as your firewall settings may be controlled by a third party antivirus software. If this is the case, open the antivirus software and turn off the firewall if the software does not prevent you from making such changes to its settings.

Note, however, that you will need to readjust the settings as soon as you activate your version of Windows 10. This is due to the fact that turning off your firewall settings permanently may lead to exposure to worms and other malicious programs.

Method Three: Activate Windows by Phone

Activation of Windows via phone is another option for individuals experiencing error code 0xc004fc03. The activate by phone option in the Update & Security tab will be available once you fail to activate Windows 10. To complete this manual repair method, follow the steps below.

• Step one: Select Settings
• Step two: Click Update & security
• Step three: Select Activate by phone
• Step four: Follow the instructions provided thereafter.

This is one of the most effective ways to fix error code 0xc004fc03. If the issue persists, however, you can proceed to the last resort.

Method Four: Download an Automated Tool

If you wish to always have at your disposal a utility tool to fix these Windows 8 and other related issues when they do arise, download and install a powerful automated tool.

Error Code 8024402C – What is it?

When upgrading to Microsoft Windows 10, some users may encounter Error Code 8024402C. This error, while attempting to update, is a result of five possible issues. The error code itself is not a critical concern, yet while the error is occurring, users will not be able to upgrade their Windows software. As with any Microsoft error code, even if it is not critical, it is recommended that the error be addressed sooner rather than later. An insignificant error now could lead to a larger, more catastrophic error later on. Common symptoms include:

• A dialog box appears with the Error Code 8024402C when attempting to upgrade to Microsoft Windows 10.
• Your current version of Windows is unable to recognize the need for an update to Microsoft Windows 10.

Solution

Error Causes

As previously stated, there are five major reasons why error code 8024402C occurs.

One of the worst problems users can encounter on their computers is Blue Screen of Death errors as some of them are quite hard to fix. One of them is the “The driver detected a controller error” Blue Screen error. It could be followed by “DeviceIdeIdeport0 OR”, “on deviceharddisk0dr0”, or “DR3” or the name of the drive or port that’s causing the problem. If you are one of the users who encountered this error, then the suggestions provided in this post would definitely help you in fixing the problem.

Option 1 – Try to disconnect and reconnect all hardware and cables

A lot of users reported that they were able to fix the problem by disconnecting and reconnecting cables and hardware like scanners, printers, cameras can help in fixing the problem. In addition, you can also boot your computer in a Clean Boot State so that you can find the problematic hardware by hit and trial method. Refer to the steps below to do so:

• After restarting your computer, go to the Settings app and Check for Updates in the Windows Update section.

Option 3 – Try to update the BIOS

Updating the BIOS can help you fix the ATTEMPTED_WRITE_TO_READONLY_MEMORY BSOD error but as you know, BIOS is a sensitive part of a computer. Even though it is a software component, the functioning of the hardware depends on it largely. Thus, you must be careful when modifying something in the BIOS. So if you don’t know much about it, it’s best if you skip on this option and try the other ones instead. However, if you are well-versed in navigating the BIOS, then follow the steps below.

• Tap the Win + R keys to open the Run dialog box.
• Next, type “msinfo32” in the field and press Enter to open System Information.
• From there, you should find a search field on the bottom where you have to search for the BIOS version and then press Enter.
• After that, you should see the developer and version of the BIOS installed on your PC.
• Go to your manufacturer’s website and then download the latest version of BIOS on your computer.
• If you are using a laptop, make sure that you keep it plugged in until you have updated the BIOS.
• Now double click on the downloaded file and install the new BIOS version on your computer.
• Now restart your computer to apply the changes made.

Option 4 – Try running the Blue Screen Troubleshooter

You might also want to run the Blue Screen troubleshooter. It is one of the built-in tools in Windows 10 that helps users in fixing system issues including Blue Screen errors. It can be found in the Settings Troubleshooters page. To use it, refer to these steps:

• Tap the Win + I keys to open the Settings panel.
• Then go to Update & Security > Troubleshoot.
• From there, look for the option called “Blue Screen” on your right-hand side and then click the “Run the troubleshooter” button to run the Blue Screen Troubleshooter and then follow the next on-screen options. Note that you might have to boot your PC into Safe Mode.

Option 5 – Try running the Memory Diagnostic Tool

The Memory Diagnostic tool in windows can help resolve the “The driver detected a controller error” Blue Screen error by checking and automatically fixing any memory-based issues. To run it, refer to these steps:

• Tap the Win + R keys to open Run and type mdsched.exe and hit Enter to open the Windows Memory Diagnostic Tool.
• After that, it will give two options such as:
  • Restart now and check for problems (Recommended)
  • Check for problems the next time I start my computer
• Once your computer has restarted, perform a basic scan or you could also go for the “Advanced” options such as “Test mix” or “Pass count”. Simply tap the F10 key to start the test.

Note: After you select your preferred option, your computer will restart and check for memory-based issues. If it finds any issues, it will automatically fix them and if there’s no issue found, then it’s most likely not a memory-based issue so you should try the other options given below.

Option 6 – Replace your motherboard

If your computer is still under warranty, you should consider replacing your computer’s motherboard in case the options given above failed to work in fixing the Blue Screen error.

Many times we were talking and writing here on Errortools.com about security, privacy, hacking, identity theft, etc. We tried to raise important security questions and I hope I have managed to at least shed some light and change maybe some bad behaviors for some, helping them embrace better routines about their security on their PC.

As you know, Windows 10 has a complicated mechanism for Activation which helps in the verification of a genuine copy of Windows 10. However, there are times when you might encounter some errors during the activation process. One of these errors is the error code 0xc000f074. This kind of error could be due to the Key Management Service or KMS which is unreachable by the client computer or if the key used in the SLSetAuthenticationData function call is incorrect. This kind of error mostly affects surfaces on computers that are upgraded from either Windows 7 or Windows 8.1 to Windows 10. In such cases, you may encounter any of the following error messages:

“Windows is unable to reach your company’s activation service. Please connect to your corporate network. If you are connected and continue to see the error, contact your system administrator. You can also click on the error detail to find the exact error. Error code: 0xC004F074.” “Activating Windows(R), (Key hash)… Error: 0xC004F074 The Software Licensing Service reported that the computer could not be activated. No Key Management Service (KMS) could be contacted. Please see the Application Event Log for additional information.” “Error 0xC004F074, SL_E_AUTHN_MISMATCHED_KEY, The Software Licensing Service reported that the key is mismatched.”

To fix the Windows 10 Activation error 0xC004F078, you have to use the correct key for your type of Windows copy or use Command Prompt to reinstall the key or you could also try running the Activation troubleshooter.

Option 1 – Try running the Windows 10 Activation Troubleshooter

The first thing you can do to resolve the Activation error code 0xc000f074 is to run the Windows 10 Activation Troubleshooter. To do so, follow these steps:

• 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.

The Windows 10 Activation Troubleshooter will determine if your license key is a valid Windows 10 digital license for an edition that is not currently installed. If it turns out that it’s not, then the troubleshooter will show you how to install the correct edition.

Option 2 – Try to use the correct key for the type of Windows version you have

If the Windows Activation troubleshooter wasn’t able to resolve the error, then you can try using the correct key for your type of Windows version. All you have to do so is check the type of your Windows copy if it’s OEM, retail, or volume. And make sure that you have the correct, valid product key for your operating system.

Option 3 – Try to use Command Prompt to reinstall the key

• In the Start Search, type “command prompt” and right-click on Command Prompt from the search results, and then select “Run as administrator”.
• After that, execute this command to uninstall the existing key: vbs /upk
• Next, you need to install the KMS product key by executing this command: vbs /ipk <The KMS Product Key>
• Once you’re done, you will see a prompt that’ll tell you whether the operation was either successful or not.
• To active, the KMS product key online, use this command: vbs /ato
• Use this command to activate the key using the telephone: exe 4
• After you’ve activated the KMS product key, restart the Software Protection Service. You can also verify the Activation Status to check if your fix was successful or not.

Option 4 – Contact Microsoft Support for assistance

If you’re at your wits’ end in trying to upgrade your computer, you should consider contacting Microsoft Support for help as they can offer you various options that would make fixing Windows Activation error code 0xc000f074 a lot easier and faster.

If you suddenly encounter the SPECIAL POOL DETECTED MEMORY CORRUPTION Blue Screen error with a bug check value of “0x000000C1” while you are using your computer then it might be due to some problem with the hardware of your Windows 10 computer. According to security experts, it is most likely caused by the physical RAM which could be due to some error in the Realtek driver for Wireless USB 2.0 as well as corruption of the files inside the RAM, and so on. This kind of problem indicates that the driver wrote to an invalid section of the special pool. On the other hand, system files like the rtwlanu.sys or nvlddmkm.sys can also trigger the SPECIAL_POOL_DETECTED_MEMORY_CORRUPTION Blue Screen error. To resolve this Blue Screen error, you can use the options provided below as reference but before you do that, make sure to create a System Restore point first. After you have that covered, proceed to the given options below.

Option 1 – Delete the settings of the Driver Verifier Manager

• Open the Driver Verifier Manager using the Start search.
• After that, select or click on the “Delete existing settings” option and then click on Finish.
• Reboot your computer and see if it fixes the Blue Screen error or not.

Option 2 – Try to update or rollback your Network driver

If you have updated the driver software as of late and you suddenly got this BSOD error, you might have to roll back the device driver – in other words, switch back to the previous working version. To do that, follow these steps:
