How to Repair Bad_Pool_Header Error

Bluetooth troubleshooting, I believe firmly that each one of us who has Bluetooth sooner or later had some issues with it, after all, it seems that it is in nature of radio transmitters to from time to time due to nature of signal and nature of Windows loose communication between them and can cause device which seems to work properly but can not establish the connection. Most of the time Bluetooth issues are like that, the signal gets lost, the connection is broken, and establishing it again can be sometimes real pain, luckily for you, we have experience in this field and are here to help you and provide you with tips how to solve Bluetooth connection issues based on our own struggles.

1. Check if BlueTooth is ON

   Yes, this seems stupid and sounds a lot like is it plugged in but here me out. Due to lost connections and different power plans setting inside your Windows, your Bluetooth receiver might be actually turned OFF thus preventing your other device to find your computer. Checking to see if Bluetooth has been by some accident turned OFF and switching it back ON should be the first thing to do and this could be a simple solution for your problem.

2. Restart the BlueTooth device.

   Yup, another of these have you tried turning it OFF and turn it back ON advice which seems like tech cliche but in the case of Bluetooth, this can actually solve your problem. Radio signals and radio connections are not the same kinds of beasts like cable ones and sometimes Bluetooth device remembers certain information and can cause conflict. Turning it OFF and then back ON will clear its memory and cache and you will be ready for a new start hopefully solving your issue along the way.

3. Check power supply

   If your Bluetooth device does not have a battery indicator, it would be wise to check on the battery status of the device. Sometimes we forget to charge batteries, sometimes someones have drained them. Checking the battery or just checking if the power supply is working properly should not be overlooked and it definitely should be on your to-do list of quick solutions.

4. Restart PC

   Sometimes most simple solutions work and if restarting your Bluetooth device did not work, maybe restarting your PC will. When you restart the PC, you clear the cache and many other things that could potentially be the reason for connection issues.

5. Checks BlueTooth device distance from computer or interference from obstacles

   The Bluetooth device operates via radio waves, and like wi-fi, if the distance from the computer is too large or you have some thick walls in between signal will degrade and be almost useless. Be aware that your PC might catch device waves and detect them but the signal itself could be too weak for the connection to work properly. Take the device and move it closer to the PC to see if the problem will go away, if it does issue was in distance or walls.

6. Reinstall or update device drivers.

   Sometimes the issue could be in Windows update and old drivers, make sure that all of your drivers are updated with the latest version and that Windows itself has the most recent update in it. Trying to reinstall device cold also solve some the issue.

7. Remove and Pair deice again

   if you tried all previous steps, try removing the device from Windows and then pairing it again. This could solve the issue since Windows itself could have mistakenly saved it like something else and can not recognize it.

8. Use Windows troubleshooter

   If everything else failed, right-click and go to troubleshoot. Windows troubleshooter will try to find the issue and direct you to a solution.

If sadly none of these things do work, you should contact the device manufacturer since it is a very good chance that the problem is one of a hardware nature.

KMODE_EXCEPTION_NOT_HANDLED seems to be connected primarily to a third-party driver, e1d65x64.sys associated with the Intel(R) Gigabit adapter, NIC/Wired network NDIS (Network Driver Interface Specification) 6.x driver. Error is known to produce the dreaded blue screen of death or BSOD. Most usually error is connected with gaming on Windows 10 computer and it manifests itself during gaming sessions. If you are unlucky and you are faced with this unfortunate error we will be happy to try to help you and present with tips and tricks in order for you to find a solution for it. Before you proceed with the provided solutions, be sure you have sufficient disk space on the Windows drive, run Disk Cleanup and then run CHKDSK.

1) Run the Blue Screen Online Troubleshooter

Open Control Panel, change the view setting to icons. Click Troubleshooting, and click “View all” in the tasks pane. Click “Blue Screen”. This opens the Blue Screen Troubleshooter.

2) Run Driver Verifier

1. Start a Command Prompt window by selecting Run as an administrator, and type verifier to open Driver Verifier Manager.
2. Select Create standard settings (the default task), and select Next. You can also choose to Create custom settings to select from predefined settings, or to select individual options. For more information, see Driver Verifier options and rule classes and Selecting Driver Verifier Options.
3. Under Select what drivers to verify, choose one of the selection schemes described in the following table.

   Driver verifier table:

   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.

4. If you chose Select driver names from a list, select Next, and then select one or more specific drivers.
5. Select Finish, and then restart the computer.

3) Update network device drivers

Go to the official Intel website and try to find newer versions of drivers, if there are none perhaps you will need to revert back to the previous version.

4) Scan memory for issues

Run a memory test on your system, sometimes these errors can be traced back to a faulty RAM bank.

5) Stop over-clocking your PC

If you have overclocked your PC please reverse it back to its original state and see if that would solve the issue

6) Perform System Restore to the previous restore point

If none of the previous solutions have bared fruit, roll back to a previous restore point and that should solve the issue.

So far I believe each person on this planet has at least heard of Marvel superhero movies, perhaps even watched a few of them, and no wonder. Movies are spawning now over 20 titles and they are not really released as events described in them. Throw into mix TV series and you can get confused pretty fast. Now it was officially stated that all TV series that were released before Wanda vision is no canon in Marvel cinematic universe which simplify thing a little but there are still series that are.

So without further blabbering around here is a list of Marvels films and TV series in chronological order:

• Captain America: The First Avenger
• Captain Marvel
• Iron Man
• Iron Man 2
• The Incredible Hulk
• Thor
• The Avengers
• Iron Man 3
• Thor: The Dark World
• Captain America: The Winter Soldier
• Guardians of the Galaxy
• Guardians of the Galaxy Vol. 2
• Avengers: Age of Ultron
• Ant-Man
• Captain America: Civil War
• Spider-Man: Homecoming
• Doctor Strange
• Black Panther
• Thor: Ragnarok
• Ant-Man and The Wasp
• Black Widow
• Avengers: Infinity War
• Avengers: Endgame
• WandaVision
• The Falcon and The Winter Soldier
• Spiderman: Far From Home
• Loki

And there you go, if you have someone who has not yet seen movies or you would like to view that as the story is revealed and not by the date they were released now you can easily with this list.

Windows 10 has a lot of several useful features and one of them is the Nearby Sharing feature. You can access this feature by going to Start > Settings > System > Shared experiences. From there, switch on the Nearby Sharing option and select the folder where you want to download the files to. This feature is really useful as it allows you to share files. However, there were reports from a number of users recently stating that Nearby Sharing is not working on their Windows 10 computers. If you are one of the users facing this problem, you might want to try checking if the Windows 10 v1803 Update is installed on your computer or not. You could also try to check if Bluetooth supports low energy mode or you could also try bringing the device closer or check if the adapter has Bluetooth version 4.0 or later. For more information, refer to each one of the given options below.

Option 1 – Try checking if Windows 10 v1803 Update is installed

To check if the Windows 10 v1803 Update is installed on your computer, go to Start > Settings > System > About. From there, scroll down to the Windows specifications and check the Version. If it is 1803 or above, then the Nearby Sharing feature should be active on your computer. However, if you find that Windows 10 v1803 Update is not installed yet, then you need to update your computer to its latest version and then see if it fixes the problem or not.

Option 2 – Verify if Bluetooth supports low energy mode

Although low energy mode is not really necessary in using Nearby Sharing, there are some Bluetooth terminals that support low energy mode which makes a lot of difference. Thus, you need to check if Bluetooth in your computer supports low energy mode by following these steps:

• Tap the Win + R keys to open the Run dialog box.
• Next, type “devmgmt.msc” in the field and tap Enter to open the Device Manager.
• After that, expand the list of Bluetooth adapters, and then right-click on your adapter and select Properties.
• Go to the Details tab and select Bluetooth radio supports Low Energy Central Role from the drop-down menu and if its value says “<true>”, it means that your Bluetooth supports low energy mode, otherwise, it doesn’t.
• If your Bluetooth does not support low energy mode, then you might want to consider purchasing an external one.

Option 3 – Try bringing the devices closer

Nearby Sharing might not work if your devices are not close enough. Thus, you need to bring your devices closer together and see if it fixes the problem. And when you do, make sure that Network Sharing is switched on for all the concerned devices.

Option 4 – Make sure that you’re using Bluetooth version 4.0 or later

For you to use the Nearby Sharing feature, you have to make sure that the adapter for all the concerned devices is using Bluetooth version 4.0 or later. So if one of the devices or if all the devices are not using this version or later versions, then you must buy an external Bluetooth adapter for you to enjoy the Nearby Sharing feature.

If you always use Google Chrome when browsing the internet, then you might have come across an error saying, “This webpage is not available, DNS PROBE FINISHED BAD CONFIG”. If you do, then this problem certainly has something to do with the DNS since any error code which has “DNS” in it points out a network issue in the computer. Getting the DNS_PROBE_FINISHED_BAD_CONFIG error indicates that your computer is not able to connect the website because the Domain Name Server or DNS wasn’t able to resolve the website name into IP address or it is not available at all. So in this guide, we’ll help you sort out this issue in Chrome on your Windows 10 PC.

Option 1 – Check the Network Cables and restart your router then reconnect

The most obvious thing you can do first is to try checking if the network cables connected to your computer or router are properly connected or not. If it turns out that some network cables are not connected properly, then it’s probably why you’re getting the DNS_PROBE_FINISHED_BAD_CONFIG error in Chrome. And if your computer is connected via Wi-Fi, you need to make sure to restart your router once. In addition, you can also forget the Wi-Fi your computer is currently connected to and then try reconnecting again to see if it would work.

Option 2 – Flush the DNS and reset TCP/IP

Flushing the DNS and reset TCP/IP could also help in fixing the DNS_PROBE_FINISHED_BAD_CONFIG error in Chrome. To do so, refer to these steps:

• Click the Start button and type in “command prompt” in the field.
• From the search results that appear, right-click on Command Prompt and select the “Run as administrator” option.
• After opening Command Prompt, you have to type each one of the commands listed below. Just make sure that after you type each command, you hit Enter
  • ipconfig /release
  • ipconfig /all
  • ipconfig /flushdns
  • ipconfig /renew
  • netsh int ip set dns
  • netsh winsock reset

After you key in the commands listed above, the DNS cache will be flushed and the Winsock, as well as the TCP/IP, will reset.

Option 3 – Try to remove the Proxy

You can also try to remove the Proxy as it might also help you in fixing the DNS_PROBE_FINISHED_BAD_CONFIG error. Here’s how you can do it:

• Tap the Win + R keys to open the Run dialog box.
• Then type “inetcpl.cpl” in the field and hit Enter to pull up the Internet Properties.
• After that, go to the Connections tab and select the LAN settings.
• From there. Uncheck the “Use a Proxy Server” option for your LAN and then make sure that the “Automatically detect settings” option is checked.
• Now click the OK and the Apply buttons.
• Restart your PC.

Note: If you are using a third-party proxy service, you have to disable it.

Option 4 – Change the DNS

Try to use the Google Public DNS If the first option didn’t work, you can try to use the Public DNS by Google and see if it can help fix the DNS error. You have to modify the DNS settings in your system explicitly and use the DNS IP addresses.

• The first thing you have to do is right-click on the network icon in the Taskbar and select Network and Sharing Center.
• Next, click on the “Change Adapter Settings” option.
• After that, search for the network connection that you are using to connect to the internet. Note that the option might be “Wireless Connection” or “Local Area Connection”.
• Right-click on your network connection and click on Properties.
• Then select the new window to choose the “Internet Protocol 4 (TCP/IPv4)” option.
• After that, click on the Properties button and click the checkbox in the new window for the option “Use the following DNS server addresses”.
• Type in “8.8.8” and “8.8.4.4” and click OK and exit.

Option 5 – Clear Chrome’s browsing data

If your browsing data in Chrome hasn’t been cleared for some time now then that might be the reason why you’re suddenly getting the DNS_PROBE_FINISHED_BAD_CONFIG error when you browse the web. To fix this error, you need to clear your web browsing data. Refer to the following steps to do so.

• Tap the Ctrl + Shift + Delete buttons to go to the Clear browsing data section in Chrome.
• Next, set the time range to “All time” and tick all the boxes and then click on the Clear data button.
• After that, restart the Chrome browser and try to open the website you were trying to open earlier.

Option 6 – Try running the Chrome Cleanup tool

In case you don’t know, there is actually a built-in malware scanner and cleanup tool in Chrome that helps you get rid of any unwanted ads, pop-ups, and even malware, as well as unusual startup pages, toolbars, and other things that could affect the performance of the browser.

In previous versions of Windows changing the system, the font was a pretty straightforward process, but it seems Microsoft did not want this feature to keep for whatever reason and there is no option as of the time of the writing of this article to do it in standard options in Windows 10. But do not worry, you are still able to customize your Windows and choose which font would you like to see inside it in all of its dialogs. You can choose whichever font you desire, the only prerequisite is it to be installed on your system. This guide will require you to change values in the registry of Windows itself so please follow step-by-step instructions and always make a backup of the registry before changing it in order to prevent some permanent Windows issues. All of that being said, let's start.

Setting new font

First thing is to open notepad, in the notepad paste the next block of code:

Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts] "Segoe UI (TrueType)"="" "Segoe UI Bold (TrueType)"="" "Segoe UI Bold Italic (TrueType)"="" "Segoe UI Italic (TrueType)"="" "Segoe UI Light (TrueType)"="" "Segoe UI Semibold (TrueType)"="" "Segoe UI Symbol (TrueType)"="" [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontSubstitutes] "Segoe UI"="NEW_FONT"

Where in "Segoe UI"="NEW_FONT" instead of NEW_FONT you need to write the exact name of the font that you wish to use as a system font. Once you have replaced the default system font with your desired one, go to File and save as, from file type drop-down menu, choose all files and save this file as .REG type giving it whatever name you wish. When the file is saved, close notepad, right-click on the saved file and choose the merge option. Confirm with YES and click on OK. Reboot your system and your Windows will now use the font of your choice as its default system font.

Restoring default font

If you wish to return the old default system font as it was, follow the same steps but in your notepad paste this code:

Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts] "Segoe UI (TrueType)"="segoeui.ttf" "Segoe UI Black (TrueType)"="seguibl.ttf" "Segoe UI Black Italic (TrueType)"="seguibli.ttf" "Segoe UI Bold (TrueType)"="segoeuib.ttf" "Segoe UI Bold Italic (TrueType)"="segoeuiz.ttf" "Segoe UI Emoji (TrueType)"="seguiemj.ttf" "Segoe UI Historic (TrueType)"="seguihis.ttf" "Segoe UI Italic (TrueType)"="segoeuii.ttf" "Segoe UI Light (TrueType)"="segoeuil.ttf" "Segoe UI Light Italic (TrueType)"="seguili.ttf" "Segoe UI Semibold (TrueType)"="seguisb.ttf" "Segoe UI Semibold Italic (TrueType)"="seguisbi.ttf" "Segoe UI Semilight (TrueType)"="segoeuisl.ttf" "Segoe UI Semilight Italic (TrueType)"="seguisli.ttf" "Segoe UI Symbol (TrueType)"="seguisym.ttf" "Segoe MDL2 Assets (TrueType)"="segmdl2.ttf" "Segoe Print (TrueType)"="segoepr.ttf" "Segoe Print Bold (TrueType)"="segoeprb.ttf" "Segoe Script (TrueType)"="segoesc.ttf" "Segoe Script Bold (TrueType)"="segoescb.ttf" [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontSubstitutes] "Segoe UI"=-

Reboot your system and your Windows will now revert the font of your choice as its default system font.

Microsoft has cut out Russia from downloading ISO files for Windows 10 and Windows 11 as well as installation tools without any explanation or reason behind this.

If you connect via VPN to a Russian server and try to download either ISO files or installation tools you will be greeted with the error 404 and an explanation of File or Directory not found or There was a problem with your request.

At this time you can still download Windows 11 Media creation tool but once you run it will throw a 0x80072F8F-0x20000 error with text: For some unknown reason, this tool failed to run on your computer.

People in Russia can still download files if they connect via VPN and go to a server located outside Russia.

Microsoft has not published any explanation why is this happening, it might be technical difficulty or it could be on purpose.

Other histories of Microsoft vs Russia

Since the beginning of the Russian military operation in Ukraine Microsoft has been putting restrictions on Russia starting with a suspension of all sales in March, next month in April Microsoft started suspending developer's accounts on GitHub linked to sanctioned companies and the suspension was even if the developer is not working for a given company or left it.

At the beginning of this month, Microsft laid off 400 employees inside Russia as they began scaling back operations in the country but has also stated that they would continue to provide services to all contractors and customers inside Russia so this sudden blocking of downloads is unexpected and it goes against their statement.
