Error Code 0x8007007b – What is it?

This error code occurs when users fail to activate their Windows operating system. It is one of the more popular Windows error codes since it affects many versions of Windows including Windows 7, Windows 8.1, and Windows 10. Error code 0x8007007b has common symptoms which include the following:

• Inability to activate a Windows installation
• Message box highlighting error code 0x8007007b

Solution

Error Causes

Error code 0x8007007b in Windows 8.1 usually results due to one or more main clauses. Windows 8.1 users may experience this error due to the use of volume-licensed media. The error code may also arise if the activation wizard is unable to connect to Key Management Service (KMS) host computer or if corrupted system files are present on your computer.

Further Information and Manual Repair

Windows error codes such as Error code 0x8007007b can be a complicated issue, requiring the use of technical knowledge and skills. For this reason, we have listed instructions in the simplest of forms to enable even average users to successfully complete manual repair methods that will resolve error code 0x8007007b.

The same approach has been applied to all our error code solutions. See also Error Code 0x00000024 and Error Code 0x80004005.

Below are the two main methods for correcting this issue.

Method One: Use Multiple Activation Key (MAK) to Activate Windows

This method involves the use of a Multiple Activation Key (MAK) instead of the Key Management Service (KMS) to activate the Windows operating system you intend to use on your PC. This manual repair method requires the use of Command Prompt so ensure you follow the instructions provided carefully so as to avoid the risks of causing harm to your system.

• Step one: Select Windows log key + X.
• Step two: Click Command Prompt, then Admin
• Step three: Type in admin password if Command Prompt requests it
• Step four: Type slmgr -ipk followed by the MAK product key. Note that the product key should have 25 characters with dashes between them like this xxxxx-xxxxx-xxxxx-xxxxx-xxxxx

Attempt to activate your Windows installation once you’ve completed the exact instructions above. If you are unable to complete this process, consider getting help from a Windows repair technician or simply move to the next manual repair method listed below.

Method Two: Run System File Checker

System File Checker (SFC) enables Windows users to scan and repair errors or corruption on system files. Since such errors within your system files can cause error code 0x8007007b to occur, follow the steps below to fix this error code.

• Step One: Go to Start and type Command Prompt or CMD.
• Step Two: Run as Administrator
• Step Three: Type sfc /scannow with a space between “sfc” and “/scannow”.

The System File Checker tool will begin scanning your machine for corrupted or missing files in need of repair. If these files are found on your system, the tool will repair and replace them. Once this is done, restart your computer then check to see if you can now activate your Windows operating system.

Method Three: Use 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.

A few days ago we celebrated fixing of months-long PrintNightmare vulnerability by Microsoft, sadly a new bug and issue have been found. Firstly discovered Microsoft stated:

A remote code execution vulnerability exists when the Windows Print Spooler service improperly performs privileged file operations. An attacker who successfully exploited this vulnerability could run arbitrary code with SYSTEM privileges. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

A few days ago, Microsoft officially released a patch that was supposed to finally fix it. As you might recall this vulnerability was present for quite some time, Microsoft's solution after a long struggle was to elevate certain privileges to administrator account only and remove user accounts from managing printers. It complicated things a little bit but it was stated payoff was worth it. The new issue now is that on a system that already had accounts created and set, old accounts still can hijack the system, patch issues address only accounts that are created after the fix is administrated, old ones can still do whatever they want. Once again of course Microsoft has stated that until it is again resolved you should again disable the Print Spooler service as a temporary workaround.

If you encounter an error saying, “Invalid file handle” when you try to rename, copy, delete a file or other operations in your Windows 10 computer, then read on as this post will guide you in what you can do to fix it. This kind of error pops up when the operating system tries to carry out an operation on a folder or file using the following words:

CON, PRN, AUX, NUL, COM1, COM2, COM3, COM4, COM5, COM6, COM7, COM8, COM9, LPT1, LPT2, LPT3, LPT4, LPT5, LPT6, LPT7, LPT8, and LPT9

When you rename or create a folder or file using the reserved words given above, you could encounter an error that says, “The specified device name is invalid”. This occurs since these words are Windows system reserved words that you can’t use, unlike any other words. Thus, if you have a folder or file which contains any of the reserved words on another computer that runs a non-Windows operating system and you try to copy or rename it Windows, then it’s no wonder why you’re getting this error message. In such cases, you can always click on the Skip button to stop the operation. However, if there are various folders or files, you can just use the Command Prompt to carry out the task. All it takes is a simple command that will get rid of the folder as well as the files in it. How? Refer to the instructions given below. Step 1: Tap the Win + R keys to open the Run utility. Step 2: Next, type “cmd” in the field and then tap Enter to open Command Prompt. Step 3: After opening Command Prompt, execute the following command:

rd \.file-folder-path /S /Q

Note: The “rd” command will remove the directory or the folder while the “\.” command will select the current computer. The “/S” command, on the other hand, helps you in removing all the sub-directories and the files that are in the CON folder. The “/Q” command is not really mandatory since it helps you remove everything silently without any confirmation message. For example, if you have a folder named “CON” located on your Desktop, the path will be like this “C:/Users/<username>/Desktop/CON”. In this case, the command should be like this:

rd \.C:Users<username>DesktopCON /S /Q

However, if the error pops up for a whole different reason, you could use the following command instead to remove the reparse point extended functionality. Once you’ve entered the given command below, you should now be able to delete the file.

FSUTIL reparsepoint delete C:Users<username>DesktopFileName DEL C:Users<username>DesktopFileName

Error Code 0x8007232B (Code 0x8007232B) – What is it?

Error code 0x8007232B (Code 0x8007232B) is an error that occurs when you attempt to activate Windows Server 2008 or Windows Vista.

Common symptoms include:

• Attempting to activate Windows 7, Windows 8, or Windows Server 2012 and you receive an error message.
• The error message says: “Windows could not be activated. Key management services host could not be located in domain name system, please have your system administrator verify that a KMS is published correctly in DNS”
• The error message says “The directory name, file name, or volume label syntax is incorrect”.

Error Causes

• Error Code 0x8007232B occurs when you attempt to use media that is volume licensed to install: Windows 8, Windows 7, Windows Vista Enterprise, Windows Vista Business, Windows Server 2012, Windows Server 2008, Windows Server 2008 R2.
• This error code also occurs when the activation wizard is unable to connect to a Key Management Service host computer.

Further Information and Manual Repair

Error code 0x8007232B can be seen when you are trying to activate windows, on several different operating systems. This problem can usually be easily corrected, but in the event that it can't, please contact a computer repair technician. When you try to install any of the previously mentioned Windows products, they use a generic product key to install the volume-based license software. If you do have a KMS host computer configuration and see these error codes, that means the correct DNS entries are not being seen on the computer. If there is not a KMS host computer setup, you need to do this setup, otherwise switch to a MAK product key method, and activate the volume license installation that way.

Method One:

Using a Multiple Activation Key as opposed to KMS activation

1. Click the Start icon, click on All Programs, click on Accessories, right-click on Command prompt.
2. Click on “Run as administrator”. Type in the password or provide confirmation if prompted for administrator password or confirmation.
3. When asked for the command prompt, enter in the following and then hit the Enter buuton: slmgr -ipk xxxxx-xxxxx-xxxxx-xxxxx-xxxxx  Note: this placeholder represents the MAK product key.

Method Two:

Configure a KMS host server for the clients to activate against.

A KMS host server needs to be configured for the clients to activate against. When there are no KMS host servers configured near you, install and activate a KMS server key. After this, configure a computer on the network to host this KMS software and publish the Domain Name System (DNS) settings.

Method Three:

When the client cannot locate a KMS host on the network for activation:

1. Verify that your computer has the KMS host installed and activated by using a KMS key that is registered in DNS. You will follow these steps to do that:

1. Click the Start button, click on All Programs, click Accessories, and then right-click on Command Prompt.
2. Click on Run as Administrator. Type the password or provide confirmation if you are asked for an administrator password or for confirmation.
3. In the command prompt box, type the following command and press ENTER: nslookup -type=all _vlmcs.tcp>kms.txt
4. Then open the KMS.txt file generated by this command. The file will contain at least one entry that relays the SRV service location.

2.  A KMS host server registers a DNS SRV record once every 24 hours by default. You should check the registry to see if the KMS host server is registering with the DNS. Follow these steps to do so:

1. Click on Start, type in regedit, and then press Enter.
2. Locate HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsNTCurrentVersionSL and then click on it.
3. The KMS server does not register in DNS if the DisableDnsPublishing subkey is existing and has a value of 1. If this subkey is missing altogether, create a DWORD value called the DisableDnsPublishing. If the dynamic registration is suitable, the subkey value should be changed to 0. Right-click DisableDnsPublishing, click on Modify, enter 0 into the Value data box, and click OK.

As you know, Airplane mode is the one that gets devices in such a state where all the wireless connections are turned off. However, recently, there are some reports from users claiming that the Airplane Mode turns on by itself in their Windows 10 computers. This kind of problem could be due to an error with the Network driver, third-party applications, and many other factors. Other users also reported that the Airplane Mode automatically flickers, while some stated that they aren’t able to toggle the option for Airplane mode. There are several options you can try to resolve this problem. You can try to configure the Power Management settings for the driver or run the Network troubleshooter. You could also roll back, reinstall or update the Network driver, as well as troubleshoot the problem in a Clean Boot State. For more details, follow each one of the given options below.

Option 1 – Try configuring the Power Management settings for the driver

The first thing you can do to fix the problem is to try configuring the Power Management settings for the driver. How? Refer to these steps:

• Tap the Win + X keys to open the WinX menu and from there, select the Device Manager to open it.
• Next, expand the Network adapters and select the entry for your Wi-Fi hardware.
• After that, right-click on it and select Properties.
• From there, go to the Power Management tab and uncheck the “Allow the computer to turn off this device to save power” option.
• Once done, restart your computer and see if it has fixed the problem.

Option 2 – Try to run the Network troubleshooter

• Open the Search bar on your computer and type in “troubleshoot” to open the Troubleshoot settings.
• Next, scroll down and select the “Network Adapter” option from the right pane.
• Then click on the Run Troubleshooter” button.
• After that, your computer will check for any possible errors and will pinpoint the root cause of the problem if possible.
• Restart your computer.

Option 3 – Try to update, rollback or reinstall the Network adapter drivers

The next thing you can do to resolve the problem is to update the Network Adapter drivers by following these steps:

• Tap the Win + R keys to launch the Run window and then type in the “devmgmt.msc” command and hit Enter to open the Device Manager window.
• Under the Device Manager, you will see a list of drivers. From there, look for the Network Adapters and expand them.
• Look for the Broadcom Network Adapter and right-click on it, as well as other network adapters that have an exclamation icon, and update them all.
• Restart your PC and see if it helped in fixing the problem.

Note: If updating the network drivers didn’t help in fixing the problem, you can also try to roll back the very same drivers from their previous versions and restart your Windows 10 PC. After that, the system itself will reinstall the drivers you just uninstalled. Alternatively, you can also download and install the drivers from the manufacturer’s website directly. To reinstall the network adapter drivers, refer to these steps:

• Open the Devices Manager from the Win X Menu.
• Then locate the device drivers and right-click on them to open the Properties.
• After that, switch to the Driver tab and click on the Uninstall Device button.
• Follow the screen option to completely uninstall it.
• Finally, restart your computer. It will just reinstall the device drivers automatically.

Option 4 – Try to reset the Network Adapter

You can also try to perform a Network Reset to resolve the problem. This will reset the entire network configuration including your IP address. To perform Network Reset, follow these steps:

• Tap the Win + I keys to open Settings.
• From there, go to the Network and Internet section.
• Next, scroll down and look for “Network Reset” under the status pane.
• After that, click on Network Reset and then on Reset now to start resetting the network configuration. Once done, check if it is able to fix the error or not.

Option 5 – Try putting your computer in a Clean Boot State

You can also troubleshoot the problem in a Clean Boot state. It could be that there are some third-party applications in your computer that are causing the Airplane Mode to behave in a strange way. So, to isolate this possibility, you need to boot your computer in a Clean Boot State be using these steps:

• Log onto your PC as an administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.
• From there, go to the General tab and click “Selective startup”.
• Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
• Next, click the Services tab and select the “Hide All Microsoft Services” check box.
• Click Disable all.
• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
• After you’ve set your computer into a Clean Boot State, try to observe if the Airplane mode is now back to normal or not.

NDIS or Network Driver Interface Specification is a programming interface for the network interface cards that aids in the proper functioning of a system driver in a computer network. The NDIS helps the computer system in order to communicate with other connected devices and hardware components on a computer network. In relation, the ndis.sys file is a critical system file developed by Microsoft for the Windows operating system. As you know, sys files or system files are important parts of the Windows operating system as well as a repository of system driver settings used by Windows to communicate with the connected hardware and devices. The ndis.sys files are stored mostly in a driver folder at C:/Windows/System32/drivers and as mentioned, these files are essential for the system to function properly. Although the presence of ndis.sys system file is not yet known to affect the normal functioning of the Windows OS, some of the Windows 10 users reported that they encountered ndis.sys blue screen errors on their PCs. Blue Screen of Death errors or Stop errors usually occurs when you open a program or a function. Moreover, it could also occur when the driver gets loaded during the system startup or during system shutdown. It isn’t yet clear what really causes the ndis.sys blue screen error. However, like other Stop errors, it may occur due to corrupted files, misconfigured device drivers, bad drivers, corrupted Windows Registry, missing or damaged system files, and malicious programs. Aside from the aforementioned reasons, the ndis.sys blue screen error might also occur if your hard disk is damaged and if the RAM is corrupted. In such cases, a lot of users usually disable the ndis.sys file. However, it won’t really resolve the issue since the file is required for the normal functioning of the operating system and even when you disable the file, it’s pretty useless as the file will start all over again. In addition, you might want to disable security programs or firewalls and antivirus programs in the meantime to check if these programs are the ones that are causing the error. And if you’ve determined that none of the security programs or firewalls and antivirus programs are to blame, refer to the options below that might help you resolve the DRIVER_IRQL_NOT_LESS_OR_EQUAL or ndis.sys Blue Screen of Death error.

Option 1 – Try to update or reinstall the PC device driver

The Ndis.sys Blue screen error can occur when the device driver in your computer is outdated or corrupted. Thus, you either have to update or reinstall it to fix the issue.

• Tap the Win + R keys to launch Run.
• Type in devmgmt.msc into the box and tap Enter or click OK to open the Device Manager.
• After that, a list of device drivers will be displayed. If you see a red or yellow sign that shows up against the driver, right-click on the driver’s name and select “Update Driver Software” or “Uninstall”. And if you find any “Unknown device”, you need to update it as well.
• Select the “Search automatically for updated driver software” option and then follow the instructions to complete the process.
• Restart your PC.

Option 2 – Rollback your Network drivers

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:

• Tap the Win + R keys to launch the Run window and then type in the “devmgmt.msc” command and hit Enter to open the Device Manager window.
• Under the Device Manager, you will see a list of drivers. From there, look for the Network Adapters and expand it.
• Next, select the driver entries that are labeled appropriately other than anything in the context of the WAN Miniport.
• Then select each one of them and double-click to open a new mini window.
• After that, make sure that you’re on the Driver tab and if you are not, just navigate to it then click the Roll Back Driver button to switch back to the previous version of your Network adapters.
• Now restart your computer to successfully apply the changes made.

Option 3 – Try running the System File Checker

The SFC or System File Checker scan could detect and automatically repair damaged system files that could be causing the ndis.sys Blue Screen of Death error. SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files with good system files. To run the SFC command, follow the steps given below.

• Tap Win + R to launch Run.
• Type in cmd in the field and tap Enter.
• After opening Command Prompt, type in sfc /scannow and hit Enter.

The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

1. Windows Resource Protection did not find any integrity violations.
2. Windows Resource Protection found corrupt files and successfully repaired them.
3. Windows Resource Protection found corrupt files but was unable to fix some of them.

Option 4 – Try running the CHKDSK utility

Running the CHKDSK utility might also help you resolve the Netwtw04.sys failed BSOD error. If your hard drive has issues with integrity, the update will really fail as the system will think that it’s not healthy and that’s where the CHKDSK utility comes in. The CHKDSK utility repairs hard drive errors that might be causing the problem.

• Open Command Prompt with admin privileges.
• After opening Command Prompt, execute the following command and hit Enter:

chkdsk /f /r

• Wait for the process to be completed and then restart your computer.

Option 5 – Run the DISM Tool

The DISM tool is another command-line tool in the Windows operating system that could help users fix various corrupted system files. To use it, follow these steps:

• Open the Command Prompt as admin.
• Then type in this command: DISM /Online /Cleanup-Image /RestoreHealth
• The DISM command you entered will repair the corrupted system image. Do not close the window if the process takes a while as it will probably take a few minutes to finish.
• Restart your PC.

Option 6 – Perform a System Restore

Performing a System Restore on your computer can also help you fix the ndis.sys Blue Screen of Death error. You can do this option either by booting into Safe Mode or in System Restore. If you are already in the Advanced Startup Options, just directly select System Restore and proceed with the next steps. And if you have just booted your PC into Safe Mode, refer to the steps below.

• Tap the Win + R keys to open the Run dialog box.
• After that, type in “sysdm.cpl” in the field and tap Enter.
• Next, go to the System Protection tab then click the System Restore button. This will open a new window where you have to select your preferred System Restore point.
• After that, follow the on-screen instructions to finish the process and then restart your computer and check if the problem is fixed or not.

If you suddenly encounter an error message saying, “ File Record Segment is Unreadable ” on a blue screen while booting your PC, it means that your hard drive is in an error state. This particular blue screen of death error might have a lot of bad sectors or might have reached its end. The workarounds you can try to resolve the issue is by locating the bad sectors or checking your hard drive for any discrepancies in the mapping and fix them. Follow the detailed instructions laid out below for these workarounds.

Option 1 – Try to check for any bad sectors and wrong configurations in your hard drive

The first thing you have to check is the boot files on your PC. As you know, your PC boots from these files and if there is anything wrong with any one of them or if one of them ends up getting corrupted, you will most likely see the blue screen of death error or a prompt with an error message saying, “File record segment is unreadable”. According to some users who reported this issue, new hard drives aren’t exempted from this error. That’s why it is recommended that you carry out this solution no matter what kind of scenario you are in. You will have to launch the Command Prompt in recovery mode and see if you can fix the problem by executing the check disk commands.

• Upon booting, restart your PC and tap F11 to go to the recovery environment then select Troubleshoot.
• Next, click Advanced from the given options and select Command Prompt.
• After opening Command Prompt, execute the commands listed below, and don’t forget to hit Enter right after you type in each one of them and if you have installed Windows to some different directory, you must replace “C” with the name of the drive you’ve installed Windows with.
• chkdsk C: /r /x
• chkdsk C: /f

Note: The Chkdsk function might take a while before it finishes its operations so you need to be patient and wait until the entire process is completed. And depending on the situation, it might even take a day at most so patience is really the key here.

Option 2 – Try connecting the hard drive to a different computer

If option 1 didn’t work for you and you’re still seeing the error, you can try connecting the hard drive to a different computer and then copy the data first. Make it a priority to salvage the data just in case the hard drive won’t make it in the future. After replicating your hard drive, you can then try running the chkdsk commands that are listed in option 1 above in the new computer you’re connecting your hard drive to and make sure that you key in the correct drive letter that’s assigned to the hard drive you’re using. After executing the chkdsk commands, plug your hard drive back into the previous computer and then check if you can now boot it without any issues.

Option 4 – Replace the faulty hard drive

If none of the options provided above really worked out then maybe it’s time to consider getting a replacement for your hard drive. In about 50% of the cases about this error, some unfortunate users were left with no choice but to replace the hard drive since the problem is with the hard drive itself. Hard drives have a complex running mechanism which includes a head and the disk that rotates accordingly so you can check if the cables connected to the hard drive are connected properly and if it is in a correct position or not. In addition, you also have to make sure that the SATA adapters where the hard drive is connected are working properly. If the drive is showing problems in the I/O operation, there is little chance for you to use it as a normal hard drive. If the hard drive is in warranty, get it checked and replace it. If not, you might consider taking it to the service center for the specialists to take a look into it.

Microsoft Visual C++ Runtime Library Error

Fix Microsoft Visual C++ Runtime Library Error, Microsoft Windows operating system supports a form of shared libraries that are known as DLL (Dynamic-link libraries). These are also known as code libraries that are used by multiple processes while one copy is loaded into memory. Runtimes are also code libraries that are loaded by applications when the application is called to run on the system. The most common runtime libraries that are used today are Visual C++ Runtime Library and Java Runtime Environment. These libraries are practically used for nearly every single application you run on your system. Therefore it is very important that these libraries are in good working order. Microsoft Visual C++ Runtime Library Error occurs when this runtime library becomes corrupted. When Microsoft Visual C++ Runtime Library Error occurs, the applications powered by this runtime library fail to run smoothly, resulting in locking you out of those applications and hampering your ability to work on them. Generally speaking, this error indicates system instability and poor PC maintenance. If this error is not fixed timely it can expose your system to serious PC damages like system freeze, crashes, and data loss.

Solution

Error Causes

All of that being said, let's see what are issues that can prevent your computer or Windows from booting up and get around them so everything is back in working order.

1. Use repair tool

   Windows 10 comes with a startup repair tool that has the goal to repair and fix errors preventing Windows from booting up. To use this tool however you will need Windows 10 bootable USB stick. You can create a bootable USB directly on the Microsoft site. Once you have it ready, plug it in and reboot your computer, choose to boot from USB. When you are on the Windows setup screen, click on next and then on Repair your computer. Go to troubleshoot > Advanced options > Startup repair. When Startup repair is clicked, Windows will boot, scan files for issues, and if they are found he will automatically fix them.

2. “Windows Failed to Start” 0xc00000f error

   If you get this error on your boot of Windows, then you have corrupted boot configuration data. In order to fix this error, you will also need a bootable USB with Windows 10 on it. Make one on the Microsoft site if you don't have it and reboot your computer, boot from USB, on the setup screen click on next and then on Repair your computer. Click on Troubleshoot and then on the command prompt. In the command prompt type the following: bootrec /FixMbr bootrec /FixBoot bootrec /ScanOs bootrec /RebuildBcd exit Reboot your PC without a USB

3. Boot into safe mode

   Safe mode for Windows loads only its core without drivers and with minimal services. If you can boot into safe mode then the issue is with some application or driver causing the problem. Try the selective boot option to eliminate what is causing the error.

4. Make sure your hardware is connected

   Some RAM or hard drive out of socket can cause Windows not to be able to boot, check all connections just in case.

If everything else fails, perform a clean Windows installation. The reason for Windows not booting up can be caused by various viruses and malware also if that case it would be best to format and perform a clean install.

If you are one of the few users who is still burning CDs and DVDs, you might have come across an error that says, “Medium Speed Error” or “Power Calibration Error”. There are several factors that could cause this error but it’s most likely that the CD/DVD burner wasn’t able to determine the Optimum Power Calibration rate properly. So what is Optimum Power Calibration rate? It is a test that runs before the burning process to regulate the optimal laser power needed to complete the job. And if this process malfunctions, obviously, you won’t be able to burn the content on your CD or DVD. There are also cases when the Power Calibration error pops up for some small issues that have nothing to do with the regulation of laser power. Here are some quick fixes you can try to resolve the Power Calibration error when burning a CD or DVD.

Option 1 – Make sure you’re using good quality CD or DVD

A lot of burning issues stem down to the purchase of low CDs or DVDs to make sure that what you are using has good quality for it is not always a good idea to purchase cheap products as cheap products could also mean cheap quality.

Option 2 – Try burning at lower speeds

If you’re certain the problem is not with the CD or DVD you are using then you can try burning again, this time at lower speeds. There are instances when doing things quickly can end in a disaster such as the “Medium Speed Error” or “Power Calibration Error” you’re getting.  To fix the problem, you have to burn at a slower speed and just take the time to wait until the burning process is done.

Option 3 – Try updating your burning software

It’s always a good idea to check if the burning software you’re using requires an update especially if it’s throwing up “Medium Speed Error” or “Power Calibration Error”. Thus, you need to update your burning software right away and then try to burn your CD or DVD once the update has been completed.
