There are times when the Windows Search doesn’t work and you wouldn’t have a clue as to why it happened since it does not give any error codes. In such cases, you have to check the error logs in the Event Viewer to find out more about the problem. From there, look for an error with the Event ID 3104 in the Windows error logs and if you see an error message that says, “Enumerating user sessions to generate filter pools failed”, read on as this post will guide you in fixing the problem. Apart from the error message, you might also see more information in the details section of the log that says, “(HRESULT: 0x80040210) (0x80040210)”.
This kind of error is most likely caused by something that prohibits the search function from initializing. A lot of users assumed that it could be due to Cortana but it’s actually not. While some users also reported that they encounter the issue after they restarted their computers. This error was also reported with the same event ID 3104 on the Windows Server. According to security researchers, this error could be caused by problems in the Registry entry of Windows search. It could also be due to an issue with the SYSTEM account where it hasn’t been added to the DCOM Security. It is also possible that the Windows Search function has not been initialized.
To fix this error, you can try to rebuild the Search Index manually or run the Search and Indexing troubleshooter. You can also check the startup type of the Windows Search service or try some registry tweak.
The first thing you can do to fix the problem is to manually rebuild the Search Index. You can do that by going to Control Panel > Indexing Options and from there, click on Advanced. After that, go to the Index Settings tab and then click on Rebuild > OK. Once you’re done, check if it fixed the problem.
You could also run the Search and Indexing troubleshooter in Windows 10 as it checks whether the settings are in place and automatically corrects any issues with the Windows 10 search function. To run this troubleshooter, just click on the Start button and select Settings > Updates and Security > Troubleshoot. From there, select the Search and Indexing Troubleshooter. Once the troubleshooter is done, restart your computer and see if it fixed the error.
In this option, you have to check the startup type of the Windows Search service since the service won’t start. To do so, refer to these steps:
Before you apply some registry tweak, you need to create a System Restore point first. Once you have that covered, follow these steps:

Error CausesOne of the problems encountered by Windows users when upgrading to Windows 10 from Windows 7 or Windows 8/8.1 is the Error Code 0x80070020. This error code normally occurs when users try to download updates from the Windows Update Website or simply by upgrading to Windows 10. Error Code 0x80070020 also occurs when the device already has a Windows 10 installed.
Once this error is encountered, it will cause malfunction of update installs and display the following message:
An error (-5006 : 0x80070020) has occurred while running the setup. Or The process cannot access the file because it is being used by another process”
In an attempt to fix Error Code 0x80070020, it is important to pinpoint what the cause is. The most probable cause of this error is due to interference. This error code most likely occurs when there is another automatic update running, for instance, an Antivirus scanning in real-time. If you’re scheduled to have an automatic update during real-time scanning, the Windows 10 update might malfunction.
In trying to fix Error Code 0x80070020, you can perform manual repair methods to resolve the issue effectively and efficiently. Most Windows users can easily employ these manual repair methods, even those who do not have technical abilities. However, there are certain instances where a Windows professional’s help is needed. If you don’t want to face any risk in resolving the issue, it would be best to consult a professional Windows technician or you can also make use of a powerful automated tool.
NOTE: It is best to attend immediately to errors encountered since unresolved errors can result in slowing down your computer’s performance. This might also cause other error messages to arise such as Error Code 0x80070057.
Since Error Code 0x80070020 is most likely encountered due to interference during your update, the easiest method you can do is to close all opened programs and restart your device. After restarting, try to start the update process again.
Another quick and safe way to fix Error Code 0x80070020 is to disable your antivirus. You must take note though that in doing so, your computer will be susceptible to virus attacks. If you want to proceed with this method, follow these steps:
The Windows Update Troubleshooter may resolve many of the errors encountered by Windows users when installing updates from Windows Update. To execute the troubleshooter, follow the steps below:
Executing a clean boot means starting Windows using only a few resources, including startup programs and drivers. This safeguards minimizing conflicts and prevent software clash when an update is received. In performing a clean boot, you will be able to pinpoint what caused the manifestation of error code 0x80070020. Check Microsoft’s Support website to know how to execute a clean boot.
Performing this method is a bit risky and should be your last option if all methods were unsuccessful. This process will alter your device’s registry so you must ensure to perform accurately the steps. A single mistake can lead to modifying your registry erroneously, which might result in the occurrence of other error messages. Carefully follow the steps found on Microsoft’s Support website to successfully reset Windows Update components.
Resetting Windows Update components can also be done by implementing the following steps:
A third-party antivirus such as BitDefender may recognize the Windows Update as a threat since the new update of Windows 10 is probably not yet registered with this third-party antivirus vendor. To solve this, you must disable temporarily the antivirus before performing the update. Once the third-party antivirus is disabled, you can now proceed with the updating process. Update as well your third-party antivirus.
The Deployment Image Servicing and Management (DISM) is a command-line utility that is installed by default in Windows 10 system. This program is used to fix images in Windows. In the case of Error Code 0x80070020, the DISM can repair the recovery image in Windows 10 and can perform as a virtual hard disk as well.
/CheckHealth – to check for corrupted files or components
/ScanHealth – to check for corrupted Windows image. This may take up to 10 minutes to finish
/RestoreHealth – to check for corrupted Windows image and do an automatic repair. This may take up to 20 to 30 minutes to finish
NOTE: In an instance where you cannot locate the good files in your computer, the system image files may be corrupted. If this happens, you need to have a copy of install.wim from a computer with good Windows 10 OS or the Windows 10 ISO file. Make sure that the source of the good files has the same language, version, and edition of your OS.
Enter the following commands one by one to perform the /RestoreHealth switch using the source path location of good files you copied:
For example purposes, the “repairSource” is the source of the good files.
| Option | Recommended use |
|---|---|
| Automatically select unsigned drivers | Useful for testing on computers that are running versions of Windows that do not require signed drivers. |
| Automatically select drivers built for older versions of Windows | Useful for testing driver compatibility with newer versions of Windows. |
| Automatically select all drivers installed on this computer | Provides maximum coverage in terms of the number of drivers that are tested on a system. This option is useful for test scenarios where a driver can interact with other devices or drivers on a system. This option can also exhaust the resources available for Special Pool and some resource tracking. Testing all drivers can also adversely affect system performance. |
| Select driver names from a list | In most cases, you will want to specify which drivers to test. Selecting all drivers in a device stack allows the Enhanced I/O Verification option to track objects and check compliance because an I/O request packet (IRP) is passed between each of the drivers in the stack, which allows for a greater level of detail to be provided when an error is detected. Select a single driver if you are running a test scenario that measures system or driver performance metrics, or if you want to allocate the greatest number of resources available for detecting memory corruption or resource tracking issues (such as deadlocks or mutexes). The Special Pool and I/O Verification options are more effective when used on one driver at a time. |
-file "C:/Users/Ayush/Desktop/Powershell Script Sample.ps1"Step 8: Once done, click on OK to save the changes made and see if the task is still giving you an error or not. On the other hand, if you are still getting the same error, you can try to repair the Task Scheduler by deleting corrupted tasks. Note that a single corrupted file can cause big problems so this option is quite important. And for you to delete a corrupted task or any task from the Task Scheduler, you have to use the Registry Editor if you are not able to use the Task Scheduler interface. To do so, follow these steps:
Error code 0xc004f034 occurs when Windows 10 users fail to activate their operating system. This activation error code affects not only Windows 10 but those using other versions of the Windows operating system including Windows 8.1. Users experiencing this problem will notice the following common symptoms which occur:
Error CausesError code 0xc004f034 usually results from issues related to activation servers. In such cases when servers are busy, users will not be able to complete the activation process which would result in access to their Windows 10 edition of choice. The error code may also result from issues related to your product key. For this reason, be sure to use the correct product key when you attempt to activate Windows 10.
The completion of manual repair methods can be an effective way to correct issues like error codes in Windows 10.

If, for whatever reason, you have trouble completing the steps suggested below, feel free to contact a Windows repair technician. This type of IT professional is usually equipped with knowledge and expertise to access your particular situation. Otherwise, see the manual repair methods listed below and complete at least one method to fix error code 0xc004f034.
If there is a problem with your product key, you will need to ensure you fix it before you can resolve error code 0xc004f034. Follow the instructions below after ensuring you have a valid product key.
Your system will activate Windows 10 if the issue was related to the use of an invalid product key. However, attempt manual method two if error code 0xc004f034 reappears and you are unable to complete the activation process.
In many cases, error code 0xc004f034 occurs simply due to a busy server. This was the case in 2015 in particular when Windows users first received access to editions of Windows 10 like Windows 10 Pro. To complete this process, you will need to follow the instructions below, repeating the last step until the activation occurs.
If this method is successful, you will finally be able to update your system to the Windows 10 edition of your choice. This process may take just a few minutes – and several attempts – before you resolve the issue. Remember to be patient. However, contact a Windows repair technician to evaluate your system if the issue persists for more than a few days.
Bad or good news, depending on your view comes from RIOT for their game Valorant. It seems that Riot has decided to enforce Windows 11 TPM 2.0 feature into Valorant running on Windows 11 and there is a rumor that it will be de facto standard and that it will move to Valorant in general no matter on which system it runs.
Furthermore, there is a rumor circling around that other developers are also talking about implementing TPM 2.0 requirements so they can harvest advanced security features of Windows 11 in order to prevent hacks and other cheats in their games.
This is an interesting point to stand on, on one side, sure, advanced features that will prevent cheating and hacking is a great thing. On other hand denying access to many computers that do not support TPM 2.0 and removing them from the game can be a permanent loss of customers and therefore loss of money. It is a risk to be sure and I am not really sure that alienating gamers is a good choice for long-term income, especially when you will be able to install Windows 11 on an unsupported PC as stated by Microsoft.
We will all see how this Riot decision will reflect on their business, as not a big Valorant player myself I am not impacted too much with this decision, but it will be interesting to see if others will indeed go with this trend or they will decide to wait a while until much more PC’s are upgraded.
