Kernel Mode Heap Corruption Error in Windows

Error code 0x8007007b - What is it?

Error code 0x8007007b will present itself when Windows users are trying to activate Windows. You may try to activate it through the update and security option, but it is likely that you will receive the same error code. Error code 0x8007007b may be presented when Windows 7 and Windows 8.1 users try to upgrade and activate Windows 10 on their computer.

Common symptoms include:

• An error message will display that says Windows cannot be activated. The KMS host cannot be located in the DNS, please have the system administrator verify that the KMS is published correctly in DNS.
• Error 0x8007007b will be displayed, stating that the file or directory name or the volume label syntax is not correct.

Solution

Error Causes

There are multiple causes for the user to see this error code, including if a user is using volume-licensed media while installing a number of various Windows operating systems. This error may also be caused because the activation wizard cannot connect to a KMS host computer. It is likely that if the user has a volume-licensed form of media, they were likely given a MAK (multiple activation keys).

Further Information and Manual Repair

There are several ways to go about repairing error code 0x8007007b. It is important to try all of the methods, but if it is too difficult or you do not know what you are doing, please do contact a Windows repair technician. They will likely be able to fix the problem with ease.

Method One: Instead of KMS activation, use a Multiple Key Activation

When KMS activation is not used, and when there is not a KMS server, the product key type should then be changed to a MAK. For MSDN (Microsoft Developer Network) or TechNet, the SKUs that are listed on the media are generally volume-licensed media, and that means that the product key that is supplied is a Multiple Activation Key.

To change the KMS to a MAK, click Start, All Programs, Accessories, and then right-click on Command Prompt. Click Run as Administrator. If prompted for a password or confirmation, enter it now.

When the command prompt opens, type in the following command, and press enter after:

slmgr -ipk xxxxx-xxxxx-xxxxx-xxxxx (these x's are representative of the MAK product key).

Method Two

While on the desktop, press the Windows key and R. The Run window should appear, and then you should enter the following command: Slui 3. Press Enter and then wait for the window to appear. This window will ask for the operating system activation product key. Enter the product key and then press the Activate button. Reboot the computer. Now the Error Code 0x8007007b should be gone.

Method Three

Open the Command Prompt with access as administrator as mentioned previously. Enter the following command: sfc /scannow. The command will then complete its task. This will take a good bit of time, so leave the computer to do its work. The sfc must finish the scan. When the scan has finished, reboot the computer. Now you can check for activation. The error code should be gone.

Method Four: When the client can't locate a KMS host on the network to complete activation

This method for correction should be used when the network does have a KMS host computer setup, and the client is not able to locate the KMS host on the network to complete activation.

To verify that the computer does in fact have the KMS host installed. Click Start, All Programs, Accessories, and then right-click on Command Prompt. Run as administrator. If you are now prompted to enter a password or confirmation, do so. When the command prompt box comes up, type in the following command, and then press Enter: nxlookup -type=all_vlmcs._tcp>kms.txt

The command will generate a file, open this KMS file. The file will contain one or more entries. As a default, the KMS host server will dynamically register a DNS SRV server evidence once every 24 hours. In order to check the registry to ensure that this is happening, follow these steps:

• Click Start, type in regedit, and then press Enter.
• Locate the key HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionSL and then click on it.
• The DisableDnsPublishing subkey should be present and have a value of 1. If it is missing, create a DWORD value by right clicking DisableDnsPublishing, click Modify, in the Value Data box type in 0, and then click Okay.

Method Five: Use An Automated Tool

If you wish to always have at your disposal a utility tool to fix these Windows 10 and other related issues when they do arise, download and install a powerful automated tool.

Downloading Windows Updates does not always go smoothly as you can encounter several issues like the “Some updates did not finish downloading, We will keep trying, Error code 0x80246007” error. In fact, this error can also occur on other Windows applications like OneNote. According to security experts, this error happens for many reasons. For one, it could be that the Windows Update database is corrupted. It could also be that there is another process that’s in conflict with the Windows Update components or there might be some issue with the Background Intelligent Transfer Service (BITS). Whichever the cause may be, you can fix it by following the solutions given below.

Option 1 – Delete the contents in the Temporary folder

You can also try deleting the contents in the Temporary folder – all the downloaded, pending, or failed Windows 10 updates. You can do that using the simple and easy steps below.

• Tap the Win + R keys to open the Run dialog box.
• Then type “%temp%” in the field and press Enter to open the Temporary folder.
• After that, select all the folders and files within the Temp folder and delete all of them.

Option 2 – Try running the Windows Update Troubleshooter

Running the built-in Windows Update troubleshooter is one of the things you can first check out as it is known to automatically resolve any Windows Update errors like Error code 0x80246007. 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. After that, follow the next on-screen instructions and you should be good to go.

Option 3 – Try renaming or removing the pending .xml file

The problem might be due to some pending .xml file so you need to rename or remove it. To do so, just go to C:/Windows/WinSxS folder. From there, look for a pending .xml file – you can either rename it or delete it. This will allow the Windows Update to delete any pending tasks and build a new and fresh update check.

Option 4 – Restart the Background Intelligent Transfer Service (BITS)

The Background Intelligent Transfer Service or BITS is a part of the Windows Update service that manages the background download of Windows Update, as well as scans for new updates and so on. Thus, if your Windows Update fails a couple of times, you might want to restart BITS. For you to do that, make sure that you have admin privileges.

• Press the Win + R keys to open the Run dialog box.
• Then type “msc” in the field and hit Enter to open Services.
• After opening Services, look for the Background Intelligent Transfer Service from the list of services and then double click on it to open Properties.
• Next, set the Startup type to Manual and click on the Start button. If it doesn’t help, you can try setting it to Automatic (Delayed) and then reboot your PC.

Option 5 – Run the DISM tool

Running the DISM Tool helps in repairing the Windows System Image as well as the Windows Component Store in Windows 10. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth”.

• Open the Command Prompt with admin privileges.
• Then type in the following commands and make sure to hit Enter right after you type each one of them:
  • Dism /Online /Cleanup-Image /CheckHealth
  • Dism /Online /Cleanup-Image /ScanHealth
  • exe /Online /Cleanup-image /Restorehealth
• Do not close the window if the process takes a while as it will probably take a few minutes to finish.

Option 6 – Delete the files from the Software Distribution folder

The downloaded Windows Updates are placed in a folder called “SoftwareDistribution”. The files downloaded in this folder are automatically deleted once the installation is completed. However, if the files are not clean up or if the installation is still pending, you can delete all the files in this folder after you pause the Windows Update service. For complete instructions, refer to the steps below.

• Open the WinX Menu.
• From there, open Command Prompt as admin.
• Then type in the following command – don’t forget to hit Enter right after typing each one of them.

net stop wuauserv net start cryptSvc net start bits net start msiserver

• After entering these commands, it will stop the Windows Update Service, Background Intelligent Transfer Service (BITS), Cryptographic, and the MSI Installer
• Next, go to the C:/Windows/SoftwareDistribution folder and get rid of all the folders and files thereby tapping the Ctrl + A keys to select them all and then click on Delete. Note that if the files are in use, you won’t be able to delete them.

Option 7 – Reset the Catroot2 folder

After resetting the SoftwareDistribution folder, you need to reset the Catroot2 folder to restart the services you just stopped. To do that, follow these steps:

• Type each one of the following commands.

net start wuauserv net start cryptSvc net start bits net start msiserver

• After that, exit Command Prompt and restart your computer, and then try to run Windows Update once more.

If you’ve been using your Windows 10 PC for a long time now, you might have come across a couple of issues – from minimal ones to critical ones like the Blue Screen of Death or BSOD stop errors. One of these BSOD errors you can encounter is the DRIVER_IRQL_NOT_LESS_OR_EQUAL Blue Screen error. This particular BSOD error is caused by iaStorA.sys, iaisp64 sys, Netwtw04.sys, nvlddmkm.sys, ndis.sys, wrUrlFlt.sys, and other driver files on Windows 10. This error indicates that a kernel-mode driver tried to access pageable memory at a process IRQL that was too high. When you encounter this error, just like a typical BSOD error, your computer will abruptly stop and you will see a blue screen with an error message saying:

“Your PC ran into a problem and needs to restart. We’re just collecting some error info, and then we’ll restart for you. (100% complete) If you’d like to know more, you can search online later for this error: DRIVER_IRQL_NOT_LESS_OR_EQUAL (wrUrlFlt.sys)”

The iaStorA.sys file is a software component that’s related to the Intel Rapid Storage Technology by Intel. It is a software solution supported by Intel Smart Response Technology which allows the PC to communicate with the hardware as well as externally connected devices. The Intel Rapid Storage Technology enables the Peripheral Component Interconnect Express or PCIe storage support, serial ATA RAID or Redundant Array of Independent Disks 0, 1, 5, and 10 support, and the PUIS or power-up in standby is also supported. To resolve this kind of BSOD error, you have to update, roll back or fresh-install the problematic driver. Refer to the options laid out below for detailed instructions.

Option 1 – Try removing the Intel Rapid Storage Technology or IRST drivers

The first thing you can try is to fix the Wi-Fi driver or the Ethernet driver on your computer to resolve the BSOD error. Take note that this option works not only on Windows 10 but also other Windows versions.

• Tap the Win + R keys on your keyboard to open the Run dialog box.
• After that, type “devmgmt.msc” in the field and hit Enter or click OK to open the Device Manager.
• After opening the Device Manager, click on the “IDE ATA/ATAPI Controller” entry and expand it.
• Next, right-click on all the driver entries that are appropriately labeled, and then click on Uninstall device.
• Now restart your PC and check if the problem’s fixed or not. If not, proceed to the next given option below.

Option 2 – Try updating the Intel Rapid Storage Technology or IRST drivers

If you’ve already tried uninstalling the IRST driver but you’re still getting the DRIVER IRQL NOT LESS OR EQUAL Blue Screen error when you use your Windows 10 PC, then this means that the drivers might be corrupted or not compatible with the operating system version that you are using right now. So to fix the problem, you have to update your drivers. To do that, follow the steps below.

• The first thing you need to do is to go to your OEM’s website.
• Once you’re already on the OEM’s website, go to the Drivers section and get the latest version for your device and then try to overwrite it.

Alternatively, you can also update the drivers via the Device Manager:

• Tap the Win + R keys on your keyboard to open the Run dialog box.
• After that, type “devmgmt.msc” in the field and hit Enter or click OK to open the Device Manager.
• After opening the Device Manager, click on the “IDE ATA/ATAPI Controller” entry and expand it.
• Next, right-click on all the driver entries that are appropriately labeled, and then click the Update driver option.
• Now restart your PC and check if the BSOD error is fixed or not.

Option 3 – Try using the System File Checker via Command Prompt

System File Checker or 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 to good system files that might be causing the DRIVER IRQL NOT LESS OR EQUAL Blue Screen error. 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

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.

The GameStream is an NVIDIA service that allows users to stream games from their Windows 10 computers to other supported devices which includes the NVIDIA SHIELD devices. However, a number of users reported that the NVIDIA GameStream is not working on their Windows 10 computers. This kind of issue is most likely caused by improper installation, some glitches with the network, and many more. To fix this issue in the NVIDIA GameStream, there are several options you need to check out to fix the problem. You can try to lo logout of GameStream and try logging back in again. You could also try to update or uninstall and reinstall the drivers related to NVIDIA or fix some network glitches or update the NVIDIA SHIELD device.

• Now restart your computer to successfully apply the changes made.

Option 4 – Try fixing your network

The next thing you can do to fix the problem with the NVIDIA GameStream is to fix the glitches in your network. Make sure that you connect both of your devices to a 5 GHz Wi-Fi network and you also have to ensure that the Wi-Fi connection you’re connected to is strong enough for both the devices for the latency to go down. Once you’ve covered all of these things with your network, restart your computer and change the Wi-Fi channel both devices are connected to. This should resolve the problem.

Option 5 – Try to update the NVIDIA SHIELD device

You might also want to update the NVIDIA SHIELD device. There are times when an outdated NVIDIA SHIELD device can result to several issues like the problem with the NVIDIA GameStream. Thus, you need to update NVIDIA SHIELD and check if it fixes the problem or not.

A lot of users complain about low storage space each time a Windows Feature update is released as well as to complain about not being able to download the updates, slow update experience, and many other complaints. The main issue is that many users do not have enough storage space available on their PCs. And now to make sure that none of the updates gets stuck because of low storage space, Microsoft presented the Reserved Storage feature which comes preinstalled with v1903 or those where v1903 was clean installed. This guide will be showing you how you can enable or disable the Reserved Storage in your Windows 10 computer. As you know, the Windows Update process should have enough space so that it can download, extract and apply the update on the computer. Usually, the size of the Reserved Storage is around 7GB which gives enough space for the update, temporary files, system caches, apps, and many more. And according to Microsoft, the size of the Reserved Storage space will vary from time to time and will depend on how you use your computer.

Explanation

The Reserved Storage space feature is enabled by default on devices that come preinstalled with the May 2019 update or after performing a clean installation of the Windows 10 OS. To check if your computer has this feature, you need to go to Settings > System > Storage and from there click on the “Show more categories” link and then click on the “System & reserved” option. However, if you can’t find the Reserved Storage from the list, then it’s probably because your computer has limited space on the hard disk or it is not a fresh or new install. On the other hand, if you have this feature but have no use for it and want to disable it instead, then read on as this post will also show you how it’s done.

Solution

Keep in mind that when you disable the Reserved Storage feature, chances are, you might be unable to enable it back so you need to make sure that it’s really what you want to do before you disable it permanently. So if you really want to disable Reserved Storage, you can do so using the Registry Editor. Before you proceed, you have to create a System Restore point first and then carry out the following steps.

• Tap the Win + R keys to launch the Run utility and type “Regedit” in the field and then tap Enter to open the Registry Editor.
• Next, navigate to this registry path: ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionReserveManager
• From there, double click on the DWORD named “ShippedWithReserves” and set its value to “1”.
• Once you’re done, restart your computer and see if the Reserved Storage feature is now gone.

On the other hand, if you want to reduce the Reserved Storage space, there are two ways you can do that. First, you can go to Settings > Apps > Apps & features > Manage optional features and from there, uninstall the optional features that you do not use. The second one is you have to go to Settings > Time & Language > Language and then uninstall the languages and their add-on which you don’t use. Note: The Reserved Storage feature is also used by system processes and apps to create temporary files and once the Reserved Storage space fills up, Windows 10 will delete them automatically. It is undeniable a useful feature so disabling it is not recommended but if you are running on low storage space and don’t have much choice, then you may disable it at your own risk.

Computer voice control has moved a long way from its beginning routes and in today's age controlling your PC with voice is truly a reality and fully possible. Voice control is taking up the steam in everyday life, from simple commands in cars, Alexa, smartphones, TVs, etc. to modern computers.

Windows 10 has introduced voice control into PC with Cortana even during the installation process but a lot has changed from having a virtual assistant in begging days and in today's modern Windows 11 OS. You can now freely open apps, move, copy delete files, and even dictate in order to create a word document.

However, in order to take this advantage, you will need to turn it off first since it is disabled by default. Of course, you will need a microphone and some spare time to train Windows in understanding you properly.

Setting up Voice Control

Just like in Windows 10, in Windows 11 voice control is also in accessibility options and the first step is to turn ON Windows Speech Recognition.

Click on the Start button and type Settings into the search bar, click on Open, or press ENTER. On the left side of the settings, window locate and click on Accessibility. On the right part once Accessibility is selected scroll down and find a section titled Interaction and click on Speech. Turn on the switch next to Windows Speech Recognition.

A pop-up will appear that will lead you through the rest of the setup and that's it.

Improving Voice Control

In order to make your voice control better, if you are not satisfied with the results, you can sample more of your voice into the algorithm to tune it more to your liking. Sadly this option is still deep in Control Panel.

Click the Start button and type in Speech recognition into the search bar, look for the search result with Control Panel displayed under it, and click on Open. Click on Train Your Computer to Better Understand You and follow the instructions.

The process will probably take a few minutes. The more data you provide to the speech recognition model, the more accurate it will be when interpreting your instructions. You can train the model multiple times, and each time you do, it should improve the accuracy.

Windows 10 is by far the most personalized Windows so far, most of its personalization comes from him learning our habits on computers and setting future experiences taking them into account. One of these things that Windows likes to set for us is also the default printer. The default printer is set as one which is most used but sometimes we do not want that, we might like to use another printer as default despite Windows choosing one for us. Never worry, setting default printer is easy and this guide will take you to step by step journey of how you can do it in 5 min on your personal computer. Let us begin: First thing is to click on the windows icon on the bottom left and open start menu, from start menu click once on settings. When the settings window opens, choose DEVICES on it. Once the device window opens, click once on printers and scanners, and on the right window go to the bottom and uncheck Let windows manage my default printer. Unchecking that box will let Windows know that we do not wish anymore for him to set our default printers according to their use. Once the checkbox is clear go up to your printer list and click on the printer you wish to use as the default one. I will choose Microsoft Print to PDF as my default printer and click on it. Once the printer is clicked option menu will appear. When the option menu appears under the printer name, click on Manage which will take you to the printer management screen. When you are on the manage screen, click on the Set as default button, and you are done.

Driver state power failure error can be linked to three things happening in your computer. Incorrect power settings, driver issues, or incompatible hardware. Sadly when this error happens you only receive a blue screen of death with this message: Sadly receiving this blue screen does not really explain which of the three cases is the correct one and causing the unwanted issue. That being said, this article will not offer you a direct solution this time, it will be more like a guide on what to check and to do in order to remove this error, reason for this is the nature of the error itself. If your computer is booting properly and you can enter Windows without issues the first thing you can try is going into power options and set it to high performance, if you are on a laptop set high performance both ways, when plugged and when on battery. Power performance settings can reflect on some hardware and can cause mayhem. After setting reboot the computer and see if the error repeats itself. If the error persists go to the device manager and see if there is hardware that has any kind of warning beside it. If there is, update the driver or remove the driver of the device to see if this fixes the issue. If all of the previous two things fail there is another thing you could try. Turn off your computer and disconnect all hardware except the most basic one. Now, this may take a long period of time but boot your computer and then repeat this process but each time add a new piece of hardware to eliminate and find which one is causing the issue. When found try to see if it is repairable through driver updates or get a new device.

Recently, several Windows 10 users have reported an issue with the Windows folder sizes in their PCs. If you are one of these affected users, read on as this post will walk you through fixing this issue. For instance, if you have a folder with 100 GB worth of data and when checking its size using its properties, you see the wrong size instead of 100GB. The size displayed will most likely be a random number which can either be bigger or smaller than the real size of the folder. This incorrect folder size issue does not happen to any specific drive or certain kinds of folders as any folder can be affected by this incorrect folder size issue. When you try to rename the affected folder, the size will change but its size still remains to be incorrect. The root cause of this particular issue is in Windows 10 itself. It is a known bug that came along with one of the latest Windows Updates which prevents the File Explorer to accurately read the metadata of a certain folder or file and leads to displaying incorrect and unexpected file sizes and the reason why you might also notice that your drive is also not correct. Since this is brought upon by one of the recent or latest Windows Updates the good thing is that Microsoft will most likely release a fix on its next upcoming updates but until then, you will be left with no choice but to deal with an incorrect folder or file size. To remedy that, here are some suggestions you can try that might fix the problem.

Option 1 – Try using the System File Checker

The System File Checker or 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 to good system files that might be causing the incorrect folder or file size in Windows 10. 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

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 2 – Try resetting Windows 10

To fix the folder and file size issue, you can try resetting Windows 10. Doing so won’t get rid of any file in your system – instead of erasing all your media files and documents, this reset option resets all the system settings and files. That way, you won’t have to deal with inaccurate folders or file sizes as you browse and use your files.

Option 3 – Wait for the Windows Update

As mentioned, this is already a known issue and a lot of Windows 10 users have already complained about it to Microsoft so a bug fix will be soon released in the latest Windows Updates.
