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.

A general rule of thumb, which is followed by most users, is to download the specific missing DLL file and place it within the software’s installation directory. However, this can be harmful to your system as hackers often upload popular malicious DLL files to target systems. Thus, you should avoid downloading DLLs from the internet. And follow these steps to fix the DLL error:

• Restart your computer
• System restore to an earlier state
• Run a malware/virus scan
• Update all the hardware drivers
• Running SFC /scannow command in command prompt
• Then do as the error suggests, reinstall the program if it’s feasible. Game files can take several hours to install and therefore, reinstallation can be a cumbersome job. Also, frustrating if the error appears after reinstallation.
• Update device drivers manually, such as graphics drivers, DirectX software if you see DLL missing error while running game

Each time we turn ON our computer or wake it from hibernation we are greeted with a Windows login screen where we need to provide login credentials in order to get into Windows itself and start working. This method of preserving data and privacy is perfectly fine and as a matter of fact, it is recommended for mobile computers but if you have a home computer in a safe environment where no one will try to look at your data or rummage through your personal stuff then removing login screen is safe enough action and can cause you a lot piece, from time-saving to less frustration on every restart or sleep action. In previous Windows versions, it was much easier to turn off this feature but it seems Microsoft has determined that our privacy and security are important and somewhat removed the ability to turn OFF the lock screen. In this guide, we will show you how you can still remove the lock screen and automatically log in with your account like in the good old days. The first thing you need to do is to press ⊞ WINDOWS + R  to bring up the Run dialog In the dialog, type in netplwiz and press ENTER. You will find yourself in the User Accounts window, inside deselect Users must enter a user name and password to use this computer. Press OK Sign in the window will pop up where you will have to type in your password and confirm it in order to start the feature. After typing in your password and confirming it, press OK. That's it, next time you wake your computer from hibernation or turn it ON, you will automatically be greeted with a desktop instead of a Windows login screen.

As you know, Windows Hello offers you quick access to computers since you can log in to your Windows devices three times faster compared to passwords with the help of the camera via Face recognition and fingerprint reader. This way, Windows Hello will recognize you right away. However, there are also times when you might encounter some problems when using Windows Hello. For one, if you are trying to add the PIN method to Windows Hello on your Windows 10 computer but you suddenly encountered an error code of 0x801c004d or if you are trying to use your existing pin and you encounter an error code of 0x80070490 along with an error message that says, “Not recognized”, then read on as this post will guide you on how you can fix both of these errors. Here is the complete content for both errors:

• “0x801c004d – Unable to enroll a device to use a PIN for login”
• “0x80070490 - Not recognized, Pin and fingerprint are no longer options for signing in”

If you got any of these two errors, there are several potential fixes you can check out to resolve them. You can try to check for any Windows Updates or create the PIN again or check the CNG Key Isolation Service. You could also try to reset the TPM or create a new User Account. For more information, follow the instructions provided below.

Option 1 – Try checking for any available Windows Updates

The first thing you can do is to check for any available Windows Updates. It is possible that your computer may be outdated and is the reason why you’re having troubles with Windows Hello. To check for Windows Updates, just go to Settings and from there, head over to the Update and Security section and click on Windows Updates located on the left pane, and then click on the Check for Updates option. Wait until the process of checking updates is completed and if it finds new updates, install it. After you install the new Windows Updates, check if you can now add the PIN on Windows Hello or not.

Option 2 – Try creating the PIN again

The next thing you can do is to create the PIN again by signing out and signing in again and then try creating the PIN once more. If this does not work, you can try restarting your computer and creating the PIN again. You could also try removing the PIN and then change it.

• Remove the PIN by going to Settings > Accounts > Sign-in options.
• From there, go to the PIN section and click on the Remove button.
• You will be asked to verify your account to proceed in removing the PIN, enter your credentials.
• Restart your computer and then set up a new PIN.
• Once you’re done, restart your computer and check if the error is gone now.

Option 3 – Try checking the CNG Key Isolation Service

The CNG Key Isolation Service is the one that stores and uses long-lived keys in a secure process complying with the common criteria requirements and it is possible that the error could be related to this service. This service is hosted in the LSA processes and provides key process isolation to private keys and associated cryptographic operations as required by the common criteria. Thus, you need to check this service to see if it’s the one that’s causing the error.

• Tap the Win + R keys to open the Run dialog box and type “services.msc” in the field and hit Enter to open the Windows Services Manager.
• Next, locate the “CNG Key Isolation Service” and once you find it, double click on it to open its Properties box.
• After opening its Properties, check its Startup type and select Manual. This is the default setting and if it is Disabled, then it’s no wonder why you’re getting errors with Windows Hello, thus, you need to enable it.
• Once done, restart your computer and check if you can now add the PIN to Windows Hello. If you still get the error, then you might want to try setting the CNG Key Isolation Service from Manual to Automatic and then click on the Start button and see if it fixes the error or not.

Option 4 – Try to reset the Trusted Platform Module or TPM

You might also want to try resetting the Trusted Platform Module or TPM to fix the error. You can do this by opening Windows PowerShell and then executing the “Clear-Tpm” command. After that, check if the error is now resolved.

Option 5 – Try to create a new User Account

You could also try to create a new User Account on your Windows 10 computer to fix the Windows Hello error. Once you have created a new local user or administrator account in Windows 10, check if you are now able to add the PIN from this newly created user account.

We have all been there, unfortunately, the application freezes, and sometimes it can even freeze whole windows. Well if the whole Windows freezes because of the application there is not much we can do except hard reset but if only the application freezes we can still kill it and return the PC in working condition. The first thing you can try is to press ALT + F4, this shortcut is for closing the program, if the application is frozen Windows will try to close it when using this shortcut, and if it succeeds you will find yourself on the desktop environment in Windows with non-responsive application taken care of. If however, this fails and the application is not closed, try ending it in the task manager. To open task manager press CTRL + SHIFT + ESC, locate unresponsive application select it, and click on the end task button on the bottom right.

Although the Windows Updates do bring in new features and improvements, there are times when they also introduce issues as well. The main cause for these arising bugs is the incompatibility between the old and new software components. One of the issues brought in by such bugs is Clock is missing, invisible or black This problem was experienced by users after they recently installed a feature update. This particular bug can make the Windows clock in the taskbar appear to be black or invisible which makes it hard for users to read the time on their computers. According to experts, this bug has something to do with the Windows Themes and Aero styling. To fix this issue, here are some suggestions that could help but before you get started, you have to restart Explorer first and see if it can help in resolving the problem – if it didn’t, follow the options given below carefully.

Option 1 – Try to disable Custom Theme

It could be that the reason behind the black or invisible Windows Clock can be an old or an incompatible theme. You might have a custom theme in place and it became incompatible after an update. Thus, you can try switching to one of the default themes and then recreate your custom theme afterward. To do so, follow the steps below.

• Right-click on your desktop and select Personalize.
• Next, select Themes from the left menu and then select Windows 10 as your theme.
• After that, you can delete all the other custom themes and create them again from scratch. This should fix the black or invisible Windows 10 Clock.

Option 2 – Try to edit your existing themes

If you don’t want to get rid of your existing themes, there is an alternative solution you can try to fix the missing Windows 10 Clock albeit it’s a bit of a complex one. Follow the given steps below to modify the existing themes and fix the missing or black Windows Clock.

• First, you need to save your existing theme. Just simply right-click on your desktop and select Personalize and select Themes from the left menu.
• Next, click on the Save Theme button below your custom theme to save it. You can name the theme anything.
• After that, you can now modify the saved theme by going to C:/Users/UserName/AppData/Local/MicrosoftWindowsThemes.
• From there, look for the file with the theme name you just saved, and then right-click on the file and open it with notepad or any other text editing app.
• Now you have to look for the line that says, “Path=%SystemRoot%resourcesthemesAeroAeroLite.msstyles” and change it to “Path=%SystemRoot%resourcesthemesAeroAero.msstyles” and then save the file and rename it with some other name.
• Afterward, go back to themes and select the new theme you’ve created. This should resolve the Windows Clock issue as well as other Themes and Taskbar issues.

Option 3 – Try disabling the small icons in Taskbar

This option should help you fix any Windows Clock cases. So if your Windows Clock is nowhere to be found, you can try to disable small taskbar icons on your Windows 10 PC.

• Go to Settings > Personalization > Taskbar.
• From there turn off the toggle button for the “Use small taskbar buttons” option. Note that this solution is only a temporary one and it may or may not work in some cases.

There are instances when instead of fixing problems the Windows Update brings you problems on your Windows 10 computer. You might even see some pending Windows Updates which for some reason, refuse to install no matter what you do. The good thing is you won’t have to deal with those failed and pending updates that are incompletely downloaded to your PC as you can actually delete them. Follow the instructions prepared below to delete the failed and pending Windows Updates.

Step 1: The first thing you have to do is delete all the contents in the Temporary folder

• Tap the Win + R keys to open the Run dialog box.
• Next, type in “%temp%” in the field and hit Enter or click OK to open the Temporary folder.
• From there, select all the folders and files within the Temporary folder and then delete them all.

Note: %temp% is one of the many environment variables in Windows that could open the designated folder by Windows as the Temporary folder which is usually located at C:\Users[username]AppDataLocalTemp.

Step 2: Next, remove the pending.xml file

• Go to the C:\Windows WinSxS folder.
• Once you’ve opened the folder, look for a file named “pending.xml” file and right-click on it and you can either rename it or delete it.
• After that, the Windows Update should delete the pending tasks and build a fresh new update.

Step 3: Delete all the contents of the SoftwareDistribution folder

The Software Distribution folder in the Windows operating system is a folder that can be found in the Windows directory and is used to store files temporarily which might be required to install the Windows Update on your PC. Thus, it is required by the Windows Update and maintained by WUAgent. Aside from that, it also contains all the Windows Update History files and once you delete them, you will most likely lose the Update history. As a result, the next time you run the Windows Update, it may result in a longer detection time.

• Open the WinX Menu.
• From there, open Command Prompt as admin.
• Then type in the following command – don’t forget to hit Enter right after typing each one of them.

net stop wuauserv net stop bits

• After entering these commands, it will stop the Windows Update Service and the Background Intelligent Transfer Service.
• Next, got to the C:\Windows\Software\Distribution folder and get rid of all the folders and files thereby tapping the Ctrl + A keys to select them all and then click on Delete. Note that if the files are in use, you won’t be able to delete them.
• Once all the contents in the Software Distribution folder are deleted, restart your PC and then go back to Command Prompt and input the following commands again.

net start wuauserv net start bits

Since the folder has already been flushed, it will be populated afresh the instant your restart your computer and open Windows Update.

Step 4: Try resetting the catroot2 folder

You can also try resetting the catroort2 folder as it is known to fix tons of Windows Update issues. Both the Catroot and catroot2 are Windows operating system folders that are required for the Windows update process.  So when you run the Windows Update, the catroort2 folders stores the signatures of the Windows Update package and helps it in the installation. It makes use of the “%windir%System32catroot2edb.log” file in the updating process. Afterward, the updates are stored in the SoftwareDistribution folder which is used then by the Automatic Updates in order to execute the updating process. Keep in mind that you must not rename or delete the Catroot folder. Although the Catroot2 folder is recreated automatically by Windows, the Catroot folder isn’t.

High Efficiency Image File Format (HEIF) is a container format for individual images and image sequences. The standard covers multimedia files that can also include other media streams, such as timed text, audio, and video. A HEIF image using High-Efficiency Video Coding, HEVC, requires only about half the storage space as the equivalent quality JPEG. HEIF also supports animation and is capable of storing more information than an animated GIF or APNG at a small fraction of the size. HEIF files are a special case of the ISO Base Media File Format (ISOBMFF, ISO/IEC 14496-12), first defined in 2001 as a shared part of MP4 and JPEG 2000. Introduced in 2015, it was developed by the Moving Picture Experts Group (MPEG) and is defined as Part 12 within the MPEG-H media suite (ISO/IEC 23008-12). HEIF was adopted by Apple in 2017 with the introduction of iOS 11, and support on other platforms is growing.

HEIF files can store the following types of data:

Image items

Storage of individual images, image properties, and thumbnails.

Image derivations

Derived images enable non-destructive image editing and are created on the fly by the rendering software using editing instructions stored separately in the HEIF file. These instructions (rectangular cropping, rotation by one, two or three quarter-turns, timed graphic overlays, etc.) and images are stored separately in the HEIF file, and describe specific transformations to be applied to the input images. The storage overhead of derived images is small.

Image sequences

Storage of multiple time-related and/or temporally predicted images (like a burst-photo shot or cinemagraph animation), their properties, and thumbnails. Different prediction options can be used in order to exploit the temporal and spatial similarities between the images. Hence, file sizes can be drastically reduced when many images are stored in the same HEIF file.

Auxiliary image items

Storage of image data, such as an alpha plane or a depth map, which complements another image item. These data are not displayed as such but used in various forms to complement another image item.

Image metadata

Storage of EXIF, XMP and similar metadata which accompany the images stored in the HEIF file.
