There are times when the Windows Search results do not include what you want to search. However, if you are trying to search for something that’s located on your desktop and Libraries, they would appear right away on the search results. Actually, the issue is not with the search but with the list of files and folders that Windows can index. If you encounter this issue, read on as this post will guide you on how to fix it. The Windows 10 operating system, ever since Windows v1903 was released, offers two kinds of searches – the classic and the enhanced search. You may have to add more folders to the classic search or use the enhanced mode to resolve the issue. In other words, to fix the problem with the Start Menu Search, you can try to enable the Enhanced Mode or add folders to the Class Search or remove the excluded folders, as well as run the Search and Indexing troubleshooter. For more information, refer to each one of the options provided below.

Option 1 – Try to enable the Enhanced Mode

To fix the problem, you have to enable the Enhanced Mode search and configure the folders you want to be indexed. How? Follow these steps:

• First, you have to go to Settings > Search > Searching Windows.
• Next, select the radio button for the Enhanced option.
• After that, select the folders you want the Windows Indexer to exclude from the Enhanced Search mode.

Option 2 – Try to add folders to the Class Search

If you don’t want to enable the Enhanced search mode, then you might want to add folders that are important to you. All you have to do is configure the Search Indexing Options by following these steps:

• Go to Settings > Search > Classic and from there, click on the “Customize search locations” option.
• Next, click on Modify in the pop-up window that appears.
• Then add drives and folders that are important to you. Once the indexing is completed, Windows will be able to find the file and display it in the search results.

Option 3 – Try removing the excluded folders

If you have already enabled the Enhanced mode but your files still don’t appear, then you might want to check out the excluded folder list.

• The first thing you have to do is go to Search and from there, you will find a list of folders under the Excluded folder list.
• Next, click on the excluded folder that you want to remove by clicking on the “Remove Excluded folders” button.
• If you are using the Classic search, you have to check if the index has restrictions on the file type. You can find it in Advanced options > File Types.

Note: If you want to search in Documents, you could also enable the Index Properties and File Contents. This should resolve the problem.

Option 4 – Try to run the Search and Indexing troubleshooter

You might also want to run the Search and Indexing troubleshooter in Windows 10 as it checks whether the settings for the Windows Start Search are in place and automatically corrects any issues if the update or software installation has changed the settings. To run it just click on the Start button and select Settings > Updates and Security > Troubleshoot. From there, select the Search and Indexing Troubleshooter.

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.

There are several ways to go about repairing error code 0x8007007b. It is important to try all of the methods, but if it is too difficult or you do not know what you are doing, please do contact a Windows repair technician. They will likely be able to fix the problem with ease.

Method One: Instead of KMS activation, use a Multiple Key Activation

When KMS activation is not used, and when there is not a KMS server, the product key type should then be changed to a MAK. For MSDN (Microsoft Developer Network) or TechNet, the SKUs that are listed on the media are generally volume-licensed media, and that means that the product key that is supplied is a Multiple Activation Key.

To change the KMS to a MAK, click Start, All Programs, Accessories, and then right-click on Command Prompt. Click Run as Administrator. If prompted for a password or confirmation, enter it now.

When the command prompt opens, type in the following command, and press enter after:

slmgr -ipk xxxxx-xxxxx-xxxxx-xxxxx (these x's are representative of the MAK product key).

Method Two

While on the desktop, press the Windows key and R. The Run window should appear, and then you should enter the following command: Slui 3. Press Enter and then wait for the window to appear. This window will ask for the operating system activation product key. Enter the product key and then press the Activate button. Reboot the computer. Now the Error Code 0x8007007b should be gone.

Method Three

Open the Command Prompt with access as administrator as mentioned previously. Enter the following command: sfc /scannow. The command will then complete its task. This will take a good bit of time, so leave the computer to do its work. The sfc must finish the scan. When the scan has finished, reboot the computer. Now you can check for activation. The error code should be gone.

Method Four: When the client can't locate a KMS host on the network to complete activation

This method for correction should be used when the network does have a KMS host computer setup, and the client is not able to locate the KMS host on the network to complete activation.

To verify that the computer does in fact have the KMS host installed. Click Start, All Programs, Accessories, and then right-click on Command Prompt. Run as administrator. If you are now prompted to enter a password or confirmation, do so. When the command prompt box comes up, type in the following command, and then press Enter: nxlookup -type=all_vlmcs._tcp>kms.txt

The command will generate a file, open this KMS file. The file will contain one or more entries. As a default, the KMS host server will dynamically register a DNS SRV server evidence once every 24 hours. In order to check the registry to ensure that this is happening, follow these steps:

• Click Start, type in regedit, and then press Enter.
• Locate the key HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionSL and then click on it.
• The DisableDnsPublishing subkey should be present and have a value of 1. If it is missing, create a DWORD value by right clicking DisableDnsPublishing, click Modify, in the Value Data box type in 0, and then click Okay.

Method Five: Use An Automated Tool

If you wish to always have at your disposal a utility tool to fix these Windows 10 and other related issues when they do arise, download and install a powerful automated tool.

In case you don’t know, Windows 10 supports installation and use of a number of removable devices which includes plug and plays mouse, keyboard, and other USB-based devices. But this could actually pose a threat to the integrity of a computer system and thus, some organizations pose a restriction in using these kinds of devices. the restriction on these devices is also useful especially if you keep on leaving your computer idle and someone tries to mess it up by plugging in a removable device. In such situations, the restriction will defend the user against data theft. Thus, in this post, you will be guided on how you can prevent the installation of removable devices on your Windows 10 computer. There are two options that can help you in preventing the installation of any removable devices on your computer – you can either try to use the Registry Editor or use the Group Policy Editor instead. Follow whichever option you want to use the instructions given below but before you start, don’t forget to create a System Restore Point first.

Option 1 – Prevent installation of Removable Devices via Registry Editor

• Tap the Win + R keys to open the Run dialog box and type “Regedit” in the field and hit Enter to open the Registry Editor.
• Next, navigate to this registry path: HKEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftWindowsDeviceInstallRestrictions
• From there, look for a DWORD named “DenyRemovableDevices” and set its value to “0”. On the other hand, if you can’t find this DWORD, just simply create it and set its value to 0.
• Once done, exit the Registry Editor and reboot your PC to apply the changes made.

Option 2 – Prevent installation of Removable Devices via Group Policy Editor

Keep in mind that the Group Policy Editor is not available in the Home Edition of the Windows operating systems. Thus, if you are using one, just stick to the first option, otherwise, proceed to the following steps.

• Tap the Win + R keys to open the Run utility and type “gpedit.msc” and click OK or tap Enter to open the Group Policy Editor.
• After that, go to this policy setting: Computer ConfigurationAdministrative TemplatesSystemDevice InstallationDevice Installation Restrictions
• Next, look for the “Prevent installation of removable devices” entry and once you find it, set it as “Enabled”. From this window, you should see the following description of this policy setting:

“This policy setting allows you to prevent Windows from installing removable devices. A device is considered removable when the driver for the device to which it is connected indicates that the device is removable. For example, a Universal Serial Bus (USB) device is reported to be removable by the drivers for the USB hub to which the device is connected. This policy setting takes precedence over any other policy setting that allows Windows to install a device. If you enable this policy setting, Windows is prevented from installing removable devices and existing removable devices cannot have their drivers updated. If you enable this policy setting on a remote desktop server, the policy setting affects redirection of removable devices from a remote desktop client to the remote desktop server. If you disable or do not configure this policy setting, Windows can install and update device drivers for removable devices as allowed or prevented by other policy settings.”

• Then click the Apply and OK buttons to save the changes made.
• Now restart your computer to save the changes made. This should prevent the installation of any removable devices in your Windows 10 computer.

What is the Error Code 0x6d9?

If you have a firewall installed on your system, you may come across the error code 0x6d9.  This error occurs when opening Windows Firewall with advanced security. The error code 0x9d9 is displayed as:

“There was an error opening the Windows Firewall with Advanced Security snap-in. The Windows Firewall with Advanced Security snap-in failed to load. Restart the Windows Firewall service on the computer you are managing. Error code: 0x6D9”

This occurs when the Windows Firewall service is missing. The service doesn’t start due to permission errors on various registry keys. It is a critical blue screen of death error code that turns the computer screen blue and causes the Windows to shut down. If this error code is not fixed it may start appearing more and more frequently resulting in total system corruption.

Solution

Error Causes

Virtually, the underlying cause for Windows Firewall error code 0x6d9 is a damaged registry. The registry is the database of the system that saves all the activities including web browsing and programs installed and uninstalled and junk files on the PC. The registry saves all the information in the RAM, your hard disk. As the disk gets filled with files, it then requires more power to run which impacts the performance of the PC and slows it down. Simultaneously, since the hard disk is overloaded with data, it exposes the registry to file damages, fragmentation, and corruption which then eventually causes hindrance in running calling programs and running them on your system because files are either corrupt or missing. Other than cluttered disk issues, registry errors also occur due to viral and malware attacks. If the Firewall is inaccessible, your system is prone to malware.
