Bluetooth Headset in Windows gets disconnected

If you have been using Windows for quite some time now then you’re probably aware of the BIOS or UEFI password. This password lock is the one that ensures you enter the set password even before your Windows PC boots up. However, there’s just one downside with the BIOS or UEFI password – there is no recovery option, unlike your Microsoft account. Worry not though for this post will guide you on how you can set or recover a BIOS or UEFI password on your Windows computer. The BIOS or UEFI passwords are stored at the hardware level which means that unless the OEM wants or has configured a way to recover the password, it is pretty much impossible to reset it. There are times when they are so strict that the only way to get through it by contacting customer care. Note that any Windows computer with this lock can’t be unlocked by trying to reinstall Windows. In this post, you’re going to have to remove the CMOS battery temporarily, clear unknown BIOS/UEFI passwords using the bios-PW website as well as call customer care. For more details, refer to the options provided below.

Option 1 – Remove the CMOS battery temporarily

In case you didn’t know, every motherboard comes with a CMOS battery which helps the computer system to keep the clock ticking and in making sure that the BIOS settings are not lost when the computer is powered down. Every time a computer is turned on, the CMOS battery ensures that the information is available for the computer to boot up. So when you remove the CMOS battery temporarily, say about 30 seconds or a minute, the settings will be lost. There are some motherboards that are built-in ways that when you remove the battery for long, it will reset everything including the password for the BIOS or UEFI.

Option 2 – Clear the unknown BIOS or UEFI passwords using a bios-PW website

If the first option didn’t work, you can try using this BIOS Password website at http://bios-pw.org/ to clear the password.

• When prompted by the BIOS, enter the wrong password a couple of times as doing so will lock you out of the system.
• After that, you will see a new number or code on the screen which will include a message about System Disabled [XXXXX] Service TAG [YYYYY].
• Next, open the BIOS Password website and enter the XXXXX code in it and make sure to tap the Shift + Enter keys or just enter.
• Now it will open multiple unlock keys which you can use to clear out the BIOS or UEFI lock on your Windows PC.

Option 3 – Call the customer care

If the second option still didn’t work, you have to call customer care and follow their suggestions for they will walk you through fixing the problem using the service tag or might suggest that you visit a service center to make things easier for you. Note: You also have the option to set a BIOS or UEFI password. Although it isn’t recommended, you still can do it if you really want to. Remember that the BIOS or UEFI interface varies from OEM to OEM so you must find something related to either PASSWORD or SECURITY. You will have the following similar options:

• Supervisor password – it’s the same as the master password that can change important system settings.
• User password – with this password, any user can change minor settings.
• Master password – you can use this password for a hard drive or as a general password.

There are several OEMs that offer micro-control where you have to enter the BIOS password. For instance, you’ll have the option to skip for a normal restart, or when you select a boot device while you might have to enter the password for unattended reboots or when your PC is powered on, etc. And if you are here to remove the password, you need to find a remove password option in the same section. You will be prompted to enter the set password once and if it’s correct, it will remove the BIOS password. After that, you have to save and exit the BIOS then restart your computer and check if the settings are properly applied.

• Click on the Apply button and then the Ok button to save the changes
• at this point, everything is supposed to be applied and your changes should take effect immediately. However, it has come to our attention that sometimes this is not the case. If you are one of these users which for whatever reason have not experienced applying to set momentarily do not despair and follow this quick guide on how to refresh settings and apply them right away.
• Press ⊞ WINDOWS + X to open the hidden menu
• Click on command prompt (admin)
• In command prompt type in gpupdate /force and press ENTER in order to force update and set setting right away

Registry editor method

The registry editor method is a more complex one but it will be your only way of doing it if as mentioned you are running Windows 10 Home edition. As always it is highly recommended to make a backup of the Windows registry before tempering with it.

• Press ⊞ WINDOWS + R to open the run dialog
• Inside run dialog type in regedit and press ENTER to open the registry editor
• If you would like to make a backup of the Windows registry go to File > Export and save the backup on a secure location naming it as you wish
• Locate the following key inside the registry editor HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Programs
• Right-click on the right pane of the Programs key and choose the New > DWORD (32-bit) Value option
• Name the value as NoProgramsAndFeatures
• Double-click on the NoProgramsAndFeatures value to open it
• Change the value data to 1
• Save the changes
• Reboot the computer in order for changes to take effect.

note: you can always change values back in order to show again panel by changing the value to 0 in registry editor or choosing Not Configured or Disabled in the local group policy editor

The latest update from Panos Panay on Twitter is including New and redesigned Snipping tool inside Windows 11. From the shared video, we can see that it includes modern Windows 11 UI redesign and it looks and feels like a part of Windows 11. More things that can be seen from the shared video is that it looks like the new snipping tool is a merged version of the old with snip & sketch. It is good to see that it is still possible to capture screen with easier way natively inside Windows 11 but some more functionality would be more welcome I guess. Users were asking for added functions for a long time like adding simple text for example but from shared video, no new features were presented so for some users 3^rd party solutions will still be the way to go. The new and redesigned Snipping tool will roll out with the next update and we will see then about all new features inside it firsthand. Until then, take care.

This post will guide you in fixing a particular problem where your Windows 10 computer does not even let you turn it on and it appears as soon as it starts to boot the operating system and it displays an error message that says, “The Boot Configuration Data for your PC is missing or contains errors, Error code 0xc0000185”. On the other hand, it may also display a different error message saying, “The operating system couldn’t be loaded because a required file is missing or contains errors”. There are various suggestions you can try to resolve this error. You could check the physical status of your hardware or rebuild the Boot Configuration Data, use the Automatic Startup Repair or System Restore, or better yet, reset your Windows 10 computer. Since your computer will not boot, you will have to either try to get into the Advanced Startup Options screen, boot Windows 10 in Safe Mode, or use a bootable Windows 10 media to boot your computer.

Option 1 – Try to rebuild the BCD files

The first thing you can do to resolve the issue is to Rebuild Boot Configuration Data or BCD files.

• Once you’re done executing the commands given above, type “exit” to close the Command Prompt window and then restart your computer and see if it fixed error code 0xc000014c.

Option 2 – Try to run Automatic Startup Repair

In this option, you need to boot your computer into the Advanced Startup Options and from there, run the Automatic Startup Repair and then wait until the process is completed.

Option 3 – Try running System Restore in Advanced Startup Options

Since you probably can’t boot into your Windows 10 computer, you can try to run System Restore again in the Advanced Startup Options.

• Boot your computer into the Advanced Startup Options screen.
• From there, you will see some options to troubleshoot when you can’t log in to Windows in the usual way.
• Now select Troubleshoot > Advanced Options > Command Prompt.
• After that, type “rstrui” and hit Enter to execute the command which will start the System Restore process.

Option 4 – Try to perform repair install by creating a Windows 10 installation media

• Click this link and then click the Download Tool Now button.
• Next, click the “Use the tool to create installation media (USB flash drive, DVD, or ISO file)…” option and follow the next given instructions on the screen.
• Now select the ISO file option in step 5.
• After that, you should now have an ISO file.

• Then right-click on the Windows 10 ISO file and select the Open with option and then select File Explorer.
• Now click on “setup.exe” and follow the next instructions that appear on the screen. When asked, you have to select either Nothing (clean install) or Keep personal files only option. Take note that you must not select the “Keep personal files, apps, and Windows settings since it doesn’t really work.

Option 5 – Try to physically check the hardware

You should also check the physical status of the hardware in your computer. You can clean the dust off the hardware components like the Network Card of the computer. You might want to use a small blower or you could also use a soft cloth and run the components gently. Make sure that you don’t damage any parts with moisture or cause harm to any circuits while you carry out this task.

One of the biggest annoyances in Windows 10 is that it’s upgrading from one version to another. Although these upgrades are necessary to fix some bugs or improve user experience, some of them actually bring bugs into the computers instead. And in one of the recent Windows 10 updates, a lot of issues were found especially for users who use Remote Desktop on a daily basis. The error stacks up as Windows 10 Remote Desktop Protocol client is not working or won’t connect and can’t find the computer HOSTNAME generally. Based on the reports by users who experienced this issue, there are two cases around it:

1. Users who try to reach a specific website or folder on the network

Some users encounter this error when they try to run the Network Troubleshooter. Even when they add the server name inside it, it still won’t identify the problem, and unpredictably, the driver seems to appear and disappear every now and then. And even after connecting, the network commands don’t work at all. This is really troublesome for users who have lots of PCs and all the other systems do not appear on the network.

2. Remote Desktop isn’t able to find the computer HOSTNAME

Some other users reported that the error appeared when they use the classic remote desktop software. It keeps on failing and throwing the error message, “Remote Desktop can’t find the computer “HOSTNAME”. If this is the same scenario you are having, it means that “HOSTNAME” does not belong to the specified network. So you need to verify the computer name and domain where you are trying to connect to. There are times when it used to work after some users tried connecting to the domain a couple of times. However, when users try to use the UWP version of Remote Desktop, it seems to connect most of the time. This kind of problem is definitely a DNS issue. It could be that there are two different records on the DNS server which is why it connects and other times it doesn’t. When it is able to resolve the correct address, the drives connect to the PC however, after a couple of minutes, they will suddenly go missing. Using “nslookup” for the hostname, multiple times, you can check this and see if you’ll get identical results all the time.

nslookup [–SubCommand …] [{ComputerToFind| [–Server]}]

If you’ve determined that the drives disappear each time, you may have to change the DNS server or ask your admin to resolve the problem for you. Alternatively, you can also check out another option that has worked for a lot of users. This second option is disabling the IPv6 on the network adapter. In case you don’t know, Windows 10 prefers IPv6 over IPv4 so if you now have issues using IPv6 to connect to the servers, you can change your computer’s settings so that it’ll only use IPv4 instead of IPv6. To do so, follow these instructions:

• Open Settings > Network and Internet > Ethernet > Change Adapter options.
• From there, right-click on the adapter for where you want to disable it and then select Properties.
• Next, look for the checkbox labeled, “Internet Protocol Version 6 (TCP/IPv6)” then uncheck it.
• Now click on OK and restart your PC to save the changes made.

In today's world setting up a LAN network or internet connection is no longer a daunting task that will require having a bachelor's degree in computer science nor a specialized technician. But even in the present-day environment issues and problems can occur. One of these problems is detecting or running a network at a slower 100MB speed instead of 1GB. Troubleshooting of this nature is somewhat more complex than your typical troubleshooting issue because several things including hardware could be involved in this particular problem but do not worry, we are here to back you up and guide you Setting up a home or small office network no longer requires a specialist technician to constantly monitor and optimize the LAN routers and connected PCs. As Windows networking has improved and new features have become available on the hardware, configuring a 1GB network should be as simple as connecting the LAN to a router that came with this capability. If however the network’s rated speed only gives 100MB, troubleshooting the issue is more complex. To find the problem, you’ll need to check the hardware devices, cable connections, and the software you are using to connect and manage the network.

Hardware checks

1. Check both connection jacks to see if it has any loose or frayed wires. If any of the wires are loose, it can be the cause of the performance issue. You should replace the cable if you discover damage to the connectors.
2. Inspect the entire length of the cable and check if the harness shows any clear signs of damage. A bent or damaged cable can reduce the amount of information it’s capable of transferring between the PC and LAN router. If you find any damage to the cable, replace it to restore your network speed.
3. Is the cable capable of transferring 1GB speeds? Different network cables support different network speeds. A Cat-5 cable will only provide 100MB transfers, while a Cat-5e or Cat-6 can support up to 10GB transfers. Check the cable’s labels to make sure you are using a Cat-5e or higher-rated data cable.

Now when the hardware issue is out of the way we can focus a little more on the software part.

Let's try the first easy solution, run Windows built-in troubleshooter

1. Click the Windows button and type Control Panel. Then select the top result.
2. If your Control Panel shows the Category View, change it to display Small Icons instead.
3. From the list of available applications, select Network and Sharing Center.
4. In your Network and Sharing Center, you can see the active network, set up a new network connection, troubleshoot problems, or change your adapter settings. Before making changes to your device properties, you can let Windows run a troubleshooter on your adapters to see if it can automatically fix your connection issues.
5. Click on Troubleshoot Problems from the Change Your Network Settings section.
6. In the Troubleshooter Application, scroll down and find the Network Adapter option.
7. Click on Run Troubleshooter to let Windows check your network adapter’s configuration for any issues.
8. Select the Ethernet Adapter you’re currently using from the list and click Next to proceed.
9. Wait for the process to complete and check the results. If Windows detects any issues, it will recommend a fix. However, if the configuration of your network adapters does not have any problems, you’ll see a message that Windows couldn’t detect any problems.
10. If there are any issues with the cable, the troubleshooter will detect the connection issue and request you replace the cable and connect it to your PC.
11. It can occur that even after inspecting the cable and you didn’t find any visible damage on the housing or connectors, it could still be faulty. Replace the cable with a new one and rerun the troubleshooter to see if the cable is working as required.

If the troubleshooter finished and you received a Windows Couldn’t Detect Any Issues result, you’ll need to verify your adapter’s speed settings.

1. In your Network and Sharing Center, select the Change Adapter Settings option from the left menu.
2. On the list of adapters, choose the one you’re using and click the Right Mouse Button to open the context menu.
3. Select Properties from the Context Menu to access your adapter’s settings.
4. On the Ethernet Properties window, you can enable or disable different features and install additional protocols. To change the device settings, click on Configure to continue.
5. This will open the Device Controller Properties window where you can check the status, make changes to the settings, find out information about the driver, or check historical events on the device. Select the Advanced tab to access the device settings.
6. On the Advanced tab, locate the Speed and Duplex setting.
7. The Auto-Negotiation option may cause network performance issues on certain Ethernet adapters and routers. The setting allows your adapter to change the speed settings according to the LAN configuration you connect to your PC. If you connect to different LAN networks regularly with different speeds, it can occur that the setting doesn’t update from 100MB to 1GB while switching.
8. Change the Value to match the network speed of the LAN you’re connecting to your PC and use the manual speed setting.
9. Click OK to apply the setting and test your network performance. If your adapter doesn’t have the 1GB setting available but you know the rating should go up to that speed, it could indicate that you aren’t using the right driver for the device.

If you don’t have the setting available or the device still only provides 100MB speeds after changing the Speed setting to a manual value, you may have to update the driver for the device.

1. On the Ethernet Properties Window, once again click on Configure to access the Device Properties Window. Then select the Driver Tab to access your driver details.
2. Select Update Driver from the available options.
3. On the Update Driver window, select the option to let Windows Search Automatically for Updated Driver Software.
4. Windows will connect to the internet and search for the latest drivers online. If a newer driver exists, Windows will download and install the driver for you. If you’re using the latest driver, Windows will inform you that no updated drivers are available.

If you suddenly encounter PFN_LIST_CORRUPT Blue Screen of Death error while using your computer then it means that the Page Frame Number or PFN list is corrupted. Page Frame Number is an indexing number used by the hard drive to find out the location of every single file on the physical disk. This kind of Blue Screen error is usually caused by a driver that’s passing a bad memory descriptor list and it can either be temporary or permanent. And so to fix this particular BSOD error, read on as this post contains a couple of suggestions that could help. Keep in mind that when you get a Blue Screen error like PFN_LIST_CORRUPT, the power connection to your PC must not be interrupted and so if you are using a laptop, it’s best if you connect it to a power source. On the other hand, if creating a dump from 0% to 100% takes up more than 5-10 minutes, then you have to force shut down your computer by pressing and holding the Power Key for 10 seconds or at least until the CPU lights turn off. After you do that, proceed to the troubleshooting tips prepared below.

Option 1 – Run the Blue Screen Troubleshooter

The Blue Screen troubleshooter is a built-in tool in Windows 10 that helps users in fixing BSOD errors like PFN_LIST_CORRUPT. It can be found on the Settings Troubleshooters page. To use it, refer to these steps:

• Tap the Win + I keys to open the Settings panel.
• Then go to Update & Security > Troubleshoot.
• From there, look for the option called “Blue Screen” on your right-hand side and then click the “Run the troubleshooter” button to run the Blue Screen Troubleshooter and then follow the next on-screen options. Note that you might have to boot your PC into Safe Mode.

Option 2 – Run a System File Checker scan

You can also try to run a System File Checker or SFC scan in order to scan your computer for corrupted files that might be the cause behind the PFN_LIST_CORRUPT error. Once it finds any corrupted system files, it will automatically fix them. To run System File Checker, here’s what you have to do:

• 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.

• Restart your computer after the scan is completed.

Option 3 – Check for any hard disk errors

• On your desktop, right-click on the “This PC” or computer icon and then select Manage to open the Disk Management. Here you get to check your drive’s health.
• Next, click on Disk Management on the left side panel.
• From there, check the state of your drives. If it shows that all your partitions are healthy then it means all is good and that the problem may have something to do with some physical issues with your hard drive.

You might also want to run the CHKDSK utility to help you fix any issues with your hard disk. If your hard drive has issues with integrity, the update will really fail as the system will think that it’s not healthy and that’s where the CHKDSK utility comes in. The CHKDSK utility repairs hard drive errors that might be causing the problem.

• Open Command Prompt with admin privileges.
• After opening Command Prompt, execute the following command and hit Enter:

chkdsk /f /r

• Wait for the process to be completed and then restart your computer.

• Restart your PC and then check if the Blue Screen error is now fixed or not.
