Kernel Mode Heap Corruption Error in Windows

The Local Security Authority Subsystem Service or LSASS.exe is a process in the Windows operating system that is valuable as it enforces the security policy on the computer. Every time you log in to the Windows Server, the LSASS.exe is the one that handles the password changes and creates the access tokens while updating the security log. However, it is also frequently targeted by malware and is often imitated. The original location of this file is at “C:/Windows/System32” so if you open the Task Manager and notice that a process with a similar name has a different location then it is definitely a threat and is exploiting the security of your computer. To resolve issues related to LSASS.exe, here are some fixes that could help.

Option 1 – Use the Performance Monitor’s Active Directory Data Collector

Note that this option will only work on the recent Windows server versions. Refer to the steps below to use the Performance Monitor’s Active Directory Data Collector set on your computer.

• Tap the WINKEY + R button to open the Run dialog box.
• Then type “Perfmon.msc” in the field and hit Enter to open the Performance Monitor and from there open the Server Manager.
• Next, navigate to Diagnostics > Reliability and Performance > Data Collector Sets > System from the left side of the navigation bar.
• Then right-click on “Active Directory Diagnostics” and select Start from the context menu. This will take about 5 minutes or 300 seconds depending on the performance capabilities of your hardware to gather the data required and then take some more time to compile a report from the gathered data. Note that these timings are dependent on one another.
• After the report is compiled, you can find it under Diagnostics > Reliability and Performance > Reports > System > Active Directory Diagnostics. The report will contain all the information as well as conclusions. However, it does not mean that it will also contain the exact cause of the problem with LSASS.exe. Nevertheless, it should help you in fixing the problem.

Option 2 – Try to run the System File Checker

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 the cause why the LSASS.exe file is having some issues. To run the SFC command, follow the steps given below.

• Type “cmd” in the Start search and then right-click on the appropriate search result.
• Next, select “Run as administrator” to open Command Prompt with admin privileges.
• 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.

 Now restart your computer and see if the problem is fixed or not.

Option 3 – Put your computer in a Clean Boot State

If none of the options given above helped, you can try putting your computer in a Clean Boot State as this can help you in finding any incompatible programs that’s causing the problem.

• 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.)
• From there, start to isolate the problem by checking which one of the programs you installed recently is the root cause of the problem.

Once you’ve found any incompatible programs, you need to uninstall them. Refer to the steps below to do so.

• In the search box, type in “control” and then click on Control Panel (desktop app) among the search results.
• After that, select Programs and Features from the list which will give you a list of all the programs installed on your computer.
• From there, look for the concerned program and select it and then uninstall it.

Note: If you have downloaded the app from the Windows Store, you can simply right-click on it from the application list and then uninstall it.

Error Code 0x80070490 - What is it?

When downloading a Windows update, it is important to remember that these updates are what keeps your computer safe. Some users have reported seeing error code 0x80070490 when allowing updates for their Windows PC. This error code may appear when the user is trying to connect to the update site for Windows and maybe a result of a corrupted CBS manifest. Having this error code will not only stop the update of the system, but it will also certainly halt any work being done with the computer. Quite a few Windows users have written in complaints about this error while updating from any prior Windows update to Windows 10.

Common symptoms include:

• While a user is performing the updates, the Windows computer will stop running the updates, and it will show the error code 0x80070490.
• Windows updates will not install any new features and will not install security patches.
• The computer will not continue with the Windows update, and it may revert back to the previous state that the computer was in, prior to attempting the updates.

Error Causes

There is not a lot known about what exactly causes the error code 0x80070490, but it is something critical that makes Windows abruptly stop its updates. It could be caused by a simple glitch in the computer system, or it could be caused by a larger problem. One thought is that the CBS (Component-Based Servicing) manifest can be corrupt. Another thought is that the computer's anti-virus software may be interfering with the computer's ability to perform the necessary updates.

Further Information and Manual Repair

There is very little information known about error code 0x80070490 and why it exists, but there are a few methods in which to correct it. Users should be careful when trying to fix this error themselves. If the user feels that the methods are too complicated or they are uncomfortable taking it on themselves, they should contact a Windows repair technician to fix the problem. Not all methods listed will suit the user's needs, but it is dependent upon the problem at hand as to which method will be the best fit to fix the error code. If these steps are taken and the error is not corrected, it is vital to contact the Windows repair technician.

Method One: Creating a new local account

Create a new local account on the computer, and allow administrator privileges on it. Next, move all of your documents and personal files to the new account. Delete the old account (you will no longer be using this) and switch over to the new one. After switching to the new local account, add the Microsoft account to it.

To do this, select the service and then click on Start the Service.

Method Four: Windows Update Troubleshooting

Press the Windows key plus W and then type in “troubleshooting”.  Select Troubleshooting. On the top left corner, select View All. Click on Windows Update troubleshooter. After this, follow the on-screen instructions in order to run the troubleshooter. After the troubleshooter has run, the issue should be fixed.

Recently, a number of users reported seeing plain white icons on their “.docx” files instead of the Word icon. This kind of issue is mostly caused by a conflict with the default program settings in Windows which is why you may not see any Microsoft Word icon on your .docx files. So if you suddenly find that the Microsoft Word icon is either blank or missing and does not show properly on .doc and .docx document files of Office on your Windows 10 computer, then you can check out the potential solutions outlined below. Before you proceed, you can try to restart your computer as there are instances when a simple system restart can resolve some issues like this one. However, if it does not help, create a System Restore point first. This is to ensure that you can always undo the changes you are about to make in case something goes wrong. Once you have that covered, proceed to the following options.

Option 1 – Try to configure .docx files to open with “winword.exe”

You can try configuring the .docx files to open with the winword.exe in order to fix the problem.

• Right-click on a .docx file and select the “Open with…” option.
• After that, if a prompt appears with a message saying, “How do you want to open this file”, select the “More apps” option to proceed.
• Next, scroll down and check the checkbox that says, “Always use this app to open .docx files” option.
• Then click on the “Look for another app on this PC” link and choose the WINWORD.exe application from one of the following paths based on the installed Office version in your computer and click Open:
  • Word 2016 (64-bit): C:/Program Files/Microsoft Office/root/Office16
  • Word 2016 (32-bit): C:/Program Files (x86)/Microsoft Office/root/Office16

• Now check if you can now see the Word icon on the .doc or .docx files.

Option 2 – Try changing the default Word icon via Registry Editor

• Tap the Win + R keys to open the Run utility.
• Then type “Regedit” in the field and hit Enter to open the Registry Editor.
• Next, navigate to this path located in the left pane: HKEY_CLASSES_ROOTWord.Document.12DefaultIcon
• From there, double click on the default value at the right pane and based on the Word version you are using as well as the architecture (32 bit or 64 bit) and then copy-paste the corresponding value in the Value data box:
  • For Word 2016 (64-bit) keep it as C:/Program Files/Microsoft Office/root/Office16/wordicon.exe,13
  • For Word 2016 (32-bit) Keep it as C:/Program Files (x86)/Microsoft Office/root/Office16/wordicon.exe,13

• Once you’re done, tap Enter and then close the Registry Editor.
• Restart your computer and see if the problem’s fixed.

Option 3 – Try to rebuild the Icon cache

You may want to rebuild the Icon cache as it could also help fix the issue.

As you know, the functioning of the Windows Sandbox feature is supported by various components in the background of the Windows operating system. And the only way for you to enable the Windows Sandbox feature in your computer is through the Turn Windows features on or off utility. This feature will work directly on the basis of Virtualization which is also supported by Hyper-V. However, there are some reports claiming that some computers have the Windows 10 Sandbox item greyed out in the Turn Windows features on or off utility. Thus, in this post, you will be guided on what you can do to resolve such a problem in your Windows 10 computer. In this kind of problem, you should know that this has something to do with the Second Level Address Translation which is one of the important pillars of how the Windows 10 Sandbox feature functions. Thus, if the Second Level Address Translation or SLAT feature in Windows Sandbox is not supported by the CPU of your computer, there is no way for you to use Windows Sandbox on your computer. On the other hand, if SLAT is supported, then there is definitely something you can do to resolve the greyed-out Sandbox item in Windows 10.

To get started, follow the steps provided below.

Step 1: First, you have to boot into the BIOS of your PC. Step 2: After that, make sure that the following options are set to their respective configurations:

• Hyper-V – Enabled
• VM Monitor Mode – Yes
• Virtualization – Enabled
• Second Level Address Translation (VT-d or RVI) – Enabled
• Data Execution Prevention – Enabled

Step 3: Once you’re done, save the configuration and then restart your Windows 10 computer as usual. Step 4: Once your computer has restarted, you should see the same option in the Turn Windows features on or off utility and it should no longer be greyed out. Then you can now enable the feature and follow the onscreen instructions need to use the feature as best as you can.

As you know, Windows 10 offers its users tons of options to log in to their computers. This includes simple and easy methods like PIN and complex ones like the Windows Hello Face unlock.

Due to its hybrid core technology, the Alder Lake line of processors had some DRM issues with some game titles where DRM protection software detected hybrid core design switching via manager as a hack attempt and prevented the game from working properly. Over 50 titles were affected by this issue, now only 3 remain still affected but it is being worked on them so that can be also resolved. Intel says that the remedy to the issue for these games is the scroll lock fix which can be done so by enabling Legacy Game Compatibility mode from the BIOS of your motherboard. When running the said games, you can press scroll lock to park the E-cores on Intel's Alder Lake Desktop CPUs to get rid of DRM issues. Certain motherboard manufacturers such as MSI and Gigabyte have made this even easier through software tools with which you don't have to access the BIOS. All you need to do is select a button in the tool which works on both Windows 11 and Windows 10 operating systems and you will enable compatibility mode.

As you know, just like other web browsers, Google Chrome offers Incognito Mode or private browsing which you can use to make sure that your browsing activities are not being tracked by any websites you visit and it also keeps targeted ads at bay. On the other hand, signing in to a website, even when in Incognito Mode is a different thing since that website can track your browsing activities. Thus, Incognito Mode is still useful especially if you want to browse the web safely and without getting tracked except when you log in to some site. However, there have been reports recently that Incognito Mode is missing in Chrome and users are clueless as to how or why it happened. If you are one of them, worry not for this post will walk you through what you can do if there’s no Incognito Mode in Chrome on your Windows 10 computer. This is an unusual and strange issue since the Incognito Mode in Chrome is available by default and you don’t have to do anything to enable it. It is possible that there might be corruption in the Windows Registry which caused the disappearance of Incognito Mode, worry not though for there are some tweaks you can apply to restore the missing Incognito Mode. To apply these tweaks, you need to create first a System Restore point, and then once you’re done, follow the instructions provided below carefully. Step_1: Tap the Win + R keys to open the Run dialog box and type “Regedit” in the field and then hit Enter to open the Registry Editor. Step_2: Next, after opening the Registry Editor, navigate to this path – ComputerHKEY_LOCAL_MACHINESOFTWAREPolicies Step_3: From there, look for ChromePolicies and locate the DWORD named “IncognitoModeAvailability” and double click on it. Step_4: Edit the value of the “IncognitoModeAvailability” DWORD by changing its value from 1 to 0 so you can enable Incognito Mode in Chrome. Step_5: Once done, exit the Registry Editor and restart your computer and then check if you can now see Incognito Mode in Chrome. On the other hand, there is also another option that allows you to force open your Chrome browser in Incognito Mode. All you have to do is set the value of the “IncognitoModeAvailability” key to “2” instead of 0. This can be useful especially if you always browse the web in this mode. But you need to remember that you won’t be able to go back to the normal mode once you do this. Here are what the values of the IncognitoModeAvailability DWORD actually mean:

• 0 – Incognito mode is enabled by default
• 1 – Incognito mode is disabled
• 2 – Chrome is forced to always open in Incognito mode

Spending a large amount of time working or gaming in front of the computer can take a toll on your health. And as someone who indeed spends a large amount of time in front of the computer, I would like to share some insights about how can you be happy and healthy at the same time by incorporating some practices and habits.

Get good chair

This is first on the list because it matters the most. A proper sitting chair is essential for back health. If your budget allows it, do yourself a favor and get an anatomic sitting chair or gaming chair with lumbar support. It costs but it is worth it.

Learn to sit properly

As the important chair is, sitting properly is also as important as much. Your spine believe it or not is a very important part of your body and you need to take care of it. Sadly long periods of sitting sessions are bad for muscles around the spine that could reflect on the spine itself. Keep your back straight and keep your head not down nor up, place it in a position like when you are walking so the spine that is going from your head is in line with the spine on your back.

Stretch

By medical standards, each hour of sitting should be accompanied by a stretch session since sitting itself is placing too much pressure on certain muscles and blood circulation is lowered. Changing leg position and doing just a little stretch each hour can be really beneficial for your health in long run.

Take breaks

Yes, playing games is fun and most of the time we do not want to stop playing, especially if we are winning but taking breaks is essential for your personal health. Old saying goes that overdoing anything is bad and this applies true even to things that we do for pleasure and relaxation. Take periodic breaks to stretch, stand up and maybe even walk just a little.

Drink water

During long work hours or long gaming sessions, it is not uncommon that we are so focused on our activity that we forget to take our water intake. Approximately 2liters of water per day is needed for an adult person to function properly during that day and if you spend long times in front of a PC do not forget to drink water.

Do not neglect your daily tasks

As enjoyable as it is gaming can make us forget about our daily tasks, do not neglect your life and your tasks. Remember, gaming is only OK if it does not interfere with the daily things that you need to do. Do not postpone going for groceries because of gaming, do not switch shower for another level in the game. Do all of the things you must do first and then sit and game.

Take care of yourself mentally

Having mental health is as important as having a physical one. Playing games is fun, but playing games with someone is even better, do not forget to socialize and invite some friends so you can share some fun times together. Also, detach yourself from outcomes that will come because of gaming, this is very important for gamers that do a lot of PVP games and get annoyed and angry when they lose or when some other player is talking trash. Remember, gaming is for you to relax and enjoy, not to stress you.

There is one service in the Windows operating system that is responsible for managing all the print jobs as well as handles the interaction with the printer. This service is known as the Print Spooler service. However, if it stops running, then you won’t be able to print anything on your computer. In such a case, you can try to restart the Print Spooler service, and to do that, you have to open the Windows Services Manager and look for the Print Spooler Service. Once you found it, right-click on it and select Restart. If it isn’t running, select Start and if the Service starts working again, then good but if not and you got an error message instead that says, “Windows could not start the Print Spooler service on Local Computer, Error 1068, The dependency service or group failed to start”, then read on as this post will give you a couple of suggestions you can try to resolve the issue. The reason why you could not start the service is most likely because the Print Spooler service is dependent on other services which might not be properly running. If the following services are not running then it’s no wonder why you’re getting the error.

• HTTP Service
• Remote Procedure Control (RPC) Service

You might not see the RPC service which means that the Print Spooler Service does not recognize its dependency on the RPC service. In such a case, you have to manually configure the dependency by following the options given below.

Option 1 – Try configuring the dependency via CMD

The first thing you have to do is to configure the dependency using CMD. Refer to the steps below to do so:

• Open an elevated Command Prompt.
• Then type in “sc config spooler depend= RPCSS” and hit Enter.
• After the command has been executed, restart your computer and then check if it fixed the problem. If not, proceed to the next given option below.

Option 2 – Fix dependency via the Registry Editor

You can also resolve dependency using the Registry Editor. How? Refer to these steps:

• Tap the Win + R keys to open the Run dialog box.
• Then type “Regedit” in the field and hit Enter to open the Registry Editor.
• After that, navigate to this key: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesSpooler
• Next, right-click on the “DependOnService” entry located on the right pane and select Modify.
• Now change its value data to “RPCSS” and click OK to save the changes made and then exit the Registry Editor.
• Reboot your computer and see if the issue is resolved.

Option 3 – Try running the Printer Troubleshooter

Another option you can check out is the Printer Troubleshooter. This built-in troubleshooter in Windows 10 can help you fix most print issues. It checks if you have the latest printer drivers and then tries to fix and update them automatically. Aside from that, it also checks if you have connectivity issues or if the Print Spooler and the required Services are running fine. To run it, follow the steps below.

• Tap the Win + R keys to open the Run dialog box.
• Next, type “exe /id PrinterDiagnostic” in the field and click OK or hit Enter to open the Printer Troubleshooter.
• Then click the Next button and follow the next on-screen instructions to fix the issue with the printer.

In recent times, some Windows 10 users have seen an error code BCM20702A0, when using Bluetooth and they are concerned as to what it is all about. We can say for certain that it has something to do with your Bluetooth driver. The error message in question is:

The drivers for this device are not installed. There are no compatible drivers for this device.

The problem here tends to no longer allow specific Bluetooth components to properly communicate with your Windows 10 operating system. It also affects laptops that do not have native Bluetooth support; therefore, the manufacturer installed a dongle on the inside to deliver the service. This is not the best way to do things because native support is always better. On the other hand, maybe you’re using a Broadcom USB Bluetooth dongle that is acting up, and as such, the error is showing. Below are solutions provided for this particular error and how to eliminate it.

1. Run the Bluetooth Troubleshooter

   Press ⊞ WINDOWS to open the menu and select settings In settings choose Update & Security Go to troubleshoot and on the right panel click on additional troubleshooters Click on Bluetooth Select Run the troubleshooter, then sit back and allow the tool to do its thing. Once you’ve completed the task, click on Apply this fix if any repairs are needed Reboot your computer

2. Install Broadcom driver from official website

   Windows drivers for Broadcom Bluetooth devices are no longer posted on their website. They should be available through Microsoft’s Windows Update service. If drivers were not downloaded automatically by Windows Update, use Device Manager to refresh the driver from Windows Update. However, the Broadcom Bluetooth drivers seem to be available here on the Lenovo website. To fix the BCM20702A0 driver error, you may download and install them. After downloading it, right-click on the downloaded item, and select Run as administrator. After installation, restart your computer, then check again if it works.

3. Remove all Bluetooth drivers and USB controllers

   If previous solutions did not work, go to device manager and remove all Bluetooth devices along with all USB controllers. Reboot your computer and Windows will automatically reinstall and set all devices.
