As you know, one of the useful and efficient utilities in Windows 10 is the DISM tool. It can be used with the Command Prompt command line which allows users to carry out various tasks. However, there are instances when the DISM tool could encounter some errors when you try to execute a command. One of these errors is the one that states, “The component store has been corrupted”. This kind of DISM error is due to an error in the image file. When you encounter the DISM Error 14098 when running the DISM tool, you will see the following content in the command line:

“C:>Dism /Online /Cleanup-Image /RestoreHealth /Source:c:testmountwindows /LimitAccess Deployment Image Servicing and Management tool Version: 10.0.10586.0 Image Version: 10.0.10586.0 [==========================100.0% Error: 14098 The component store has been corrupted. The DISM log file can be found at C:WINDOWSLogsDISMdism.log C:>”

There are several fixes you can check out to fix the DISM Error 14098, “The component store has been corrupted”. You can try to run the Restore Health command or reset the Windows Update components, or whitelist the dism.exe in your antivirus program, as well as try to uninstall any recently installed updates. Follow the options provided below for more details.

Option 1 – Run the Restore Health command in a Clean Boot State

• First, you need to put your computer in a Clean Boot State.
• 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.)
• Now open Command Prompt with admin privileges.
• Then type and enter this command to execute it: Dism /Online /Cleanup-Image /RestoreHealth
• Wait until the process is completed and restart your computer.

Note: If the Restore Health command fails, you can use the “/StartComponentCleanup parameter” by executing this command: Dism /Online /Cleanup-Image /StartComponentCleanup

Option 2 – Try to reset the Windows Update components

If by any chance that the second option didn’t work, resetting the Windows Update components could also help you resolve the problem. How? Refer to the following steps:

• Open Command Prompt with admin privileges.
• After that, type each one of the following commands and hit Enter after you key in one after the other.
  • net stop wuauserv
  • net stop cryptsvc
  • net stop bits
  • net stop msiserver

Note: The commands you entered will stop the Windows Update components such as Windows Update service, Cryptographic services, BITS, and MSI Installer.

  • net start bits
  • net start msiserver
• Close Command Prompt and reboot your PC.

Option 3 – Whitelist the “dism.exe” in your antivirus program

The DISM error 14098 might also be caused by your antivirus program which could be interfering it from running. To fix this, you have to whitelist dism.exe. How? Refer to these steps:

• Open the Windows Defender Security Center from the system tray area.
• Next, click the “Virus & threat protection” option and then open the “Virus and threat protection settings”.
• After that, scroll down until you find the “Exclusions” and click on the “Add or remove exclusions” option.

• Go to Settings and select Update and Security > Windows Update.

The third time is charm saying goes but not when we are talking about Microsoft. Print spooler is again in focus, in a bad way. This is the third print spooler vulnerability to emerge in just five weeks. While a critical flaw was originally identified and patched in June, a similar flaw came to light shortly after and was subsequently patched (with mixed success). Microsoft is once again advising its customers to disable Windows print spooler after a new vulnerability that allows hackers to execute malicious code on machines has emerged. While a patch fixing the flaw will be released in due course, the most effective workaround currently on the table is to stop and disable the print spooler service entirely.

"An elevation of privilege 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."

Stop this service right away or you are risking a potential attack.

1. Press ⊞ WINDOWS + X to open the hidden menu
2. Click on Power Shell (admin)
3. In Power Shell type in the following command to check if spool service is running: Get-Service -Name Spooler followed by ENTER
4. If spooler service is running type in the next command to stop it: Stop-Service -Name Spooler –Force and press ENTER
5. Then follow with this command to disable it at startup: Set-Service -Name Spooler -StartupType Disabled followed with ENTER

That’s it, we hope a patch will come soon for all the people that are using network printing and indeed need this service running in order to do work.

Diablo 2 resurrected has hit official release and servers seem to be finally taken care of and everything seems to be running smoothly now. The game also received great praise from gamers and attracted old players of the original Diablo 2 game. Speaking of old players of old Diablo 2, they can transfer their old characters into remaster and continue playing them within this new great HD environment. There are some steps and requirements but we are here to help and transferred characters will bring full stash, inventory, and equipped items with them.

Requirements

There are not many requirements for this transfer to occur but they must be respected in order to be successful. The first thing is a minor requirement and somewhat annoying but it needs to be done, firstly fire up Diablo 2 resurrected and create a character, any kind of character with any kind of name, any kind of class. This strange requirement is to actually create a character folder and register it inside D2 resurrected so we can copy old ones there. The second requirement will be that characters that you wish to be transferred must be offline characters. Old battle net online characters cannot be transferred at this moment and probably will not be in the future as well. So for all of you that wish to transfer online characters, bad luck, for the rest of us casuals playing offline single-player mode, we can enjoy our characters.

Process of diablo 2 character trasfer

The process itself of transferring characters when previously mentioned requirements are met is just a simple and copy operation. If you have somewhere backed your characters go into your backup folder and copy files in c:\users\*current user*\saved games\*diablo 2 resurrected folder* If you do not have characters backed up and just have old Diablo 2 installed and playing it, you can go to c:\users\*current user*\saved games\*diablo 2 folder* and just copy all characters files into c:\users\*current user*\saved games\*diablo 2 resurrected folder* Your old characters end with .d2s extension, grab all that you want to transfer, and copy them into D2R. Take note that copied characters cannot be brought back into Diablo 2, once they are copied into Diablo 2 resurrected all further progress on them will be tied to the new game.

Conclusion

That’s it about the transfer process and requirements for it. Fire up the new game version and enjoy.

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.
