An Easy Guide to Resolving Code 18

As you know, USB is now being widely used in all devices with USB A as the leading type with most devices based on it. Peripheral devices such as Pen Drives, External Hard disks, and many more also use a USB port. On the other hand, USB C is also coming up to be the next big standard in the computing world because of its high transfer speeds, wider compatibility as well as support for external Graphics Processing Units. However, just recently, USB 3.0 ports have been reported to cause the following error to pop up on Windows 10 computers every time a USB device is plugged in.

“Not enough USB controller resources. The controller does not have enough resources for this device.”

To fix this error, here are some guidelines you can check out. Make sure to follow them carefully.

Option 1 – Try to use a lower generation USB port

The first thing you can do is to try using a lower generation USB port as this issue mostly occurs when a device is connected to a USB 3,0 port. This means that you have to plug in your device to a USB 2.0 port and then see if it fixes the error or not. You can easily decipher a USB 3.0 port from a USB 2.0 port as the former is in blue.

Option 2 – Try to use a dock

You could also try to use a dock to resolve the error. Note that when too much power on laptops and notebooks are drawn from the USB ports and as a USB 3.0 port draws more power compared to a USB 2.0 port. Thus, if you plug in your USB storage device into a USB 2.0 port with the help of a dock, it should fix the problem.

Option 3 – Try disabling the xHCI Mode option in the BIOS

• First, boot your computer into the BIOS.
• Once your computer has booted, go to the Advanced tab.
• Next, make sure that the entry for “xHCI Pre-boot mode” is set to Disabled under the USB Configuration section.
• Now save the changes you’ve made and then restart your computer to Windows 10 and see if the error is now fixed.

Option 4 – Update or reinstall the Universal Serial Bus Controller driver

Since it could be a driver issue, you can try to update or reinstall the Universal Serial Bus Controller drivers using the Device Manager. Refer to the following steps:

• First, click the Start button and type “device manager”.
• Then click on the “Device Manager” from the search results to open it.
• From there, look for the “Universal Serial Bus controllers” option and then right click on each one of the USB drivers, especially the Generic USB Hub driver, and then select the Update Driver from the menu.
• Restart your PC and then click the “Search automatically for updated driver software” option.

Note: If updating the USB Controller drivers didn’t work, you can try to reinstall them instead.

Option 5 – Run the Hardware and Devices Troubleshooter

You could also run the Hardware and device Troubleshooter to try and fix the “Not enough USB controller resources” error.

• The first thing you need to do is click on Start and then on the gear-like icon to pull up the window for Settings.
• After opening Settings, look for the Update and Security option and select it.
• From there, go to the Troubleshoot option located on the left-hand side of the list.
• Next, select Hardware and Devices from the list and open the Troubleshooter and run it. Once it is doing its job, wait for it to complete the process and then restart the system.
• After the system restarts, check if the problem’s now fixed. If not, refer to the next option given below.

The author of the famous software library mode-ipc that gets over a million downloads per week found that it has some questionable code inside. The code itself behaves like this: if it finds out that your location is within Russia or Belarus it will try to replace the contents of all files on the computer with a heart emoji.

One important thing is that we here are not supporting the current Ukrainian situation and are against any type of violence or war but we also do not support this kind of behavior as well. If we look at this only from a technical perspective, we would then classify the mode-ipc library as malware and a harmful piece of code no matter the motivation behind it.

So this so-called protestware is well basically malware, but not always, it will protest when certain conditions are met. The issue with this is that companies and users should not be placed under harm if they do not share the personal view of the code author. Imagine if, for example, I would publish code to delete all pictures from your computer if my code found out that you do not like metal music. I guess you not liking metal music and war in Ukraine are two very different things but the source is the same, unreliable code that invades your privacy in order to serve one purpose, punishment for disagreeing with my personal views and that should not be allowed.

Not all protestware are equal, some will not harm your computer on purpose, they will just annoy you with some messages like viruses did in their infancy stages, others might place some developer sanctions but no matter the outcome basic principle is the same, it does something without user consent and without informing the user that something like that might happen.

On the internet, many blog posts and discussions were open about this issue and its morality. Discussion is still active with different takes on the situation and how to prevent it. Our take on this matter is that professional developers should have standards and not submit to doing harm for the sake of personal views and feelings.

In the long run, this kind of behavior and practice can only harm developers involved in this kind of entanglement. Infected libraries will in time stop being used since people would not trust them and authors will have a stain on their name as impulsive or not trustworthy.

If the Task Manager is either blank or is not showing processes on your Windows 10 computer, then here are a few things you can do to resolve this issue. This kind of problem can occur due to some system file corruption or some malware infection in the system.

The errors that are caused by the BIOS of your computer can get annoying as they can be hard to fix for they are really dangerous and won’t be resolved by simple fixes. This is because of the fact that these kinds of errors do not even allow you to load your operating system as it throws the error even before you can access your computer. One of these errors is the “Error 0199: System Security – Security password retry count exceeded”. Fixing this error can be quite tricky but you need not worry for you will be guided in doing so. Simply follow the given instructions below.

Option 1 – Try to update the BIOS

Updating the BIOS can help you fix the “Error 0199, Security password retry count exceeded” error but as you know, BIOS is a sensitive part of a computer. Even though it is a software component, the functioning of the hardware depends on it largely. Thus, you must be careful when modifying something in the BIOS. So if you don’t know much about it, it’s best if you skip on this option and try the other ones instead. However, if you are well-versed in navigating the BIOS, then follow the steps below.

• Tap the Win + R keys to open the Run dialog box.
• Next, type “msinfo32” in the field and press Enter to open System Information.
• From there, you should find a search field on the bottom where you have to search for the BIOS version and then press Enter.
• After that, you should see the developer and version of the BIOS installed on your PC.
• Go to your manufacturer’s website and then download the latest version of BIOS on your computer.
• If you are using a laptop, make sure that you keep it plugged in until you have updated the BIOS.
• Now double click on the downloaded file and install the new BIOS version on your computer.
• Now restart your computer to apply the changes made.

Option 2 – Try resetting the BIOS

If updating the BIOS didn’t help in fixing Error 0199, you can try to reset the BIOS instead.

• Start your computer and tap the F10 key during the booting process to enter the BIOS. If it does not work, you can try tapping the F1 or F2 key as well as the Del key.
• Once you’re already in the BIOS, tap the F9 key to get the prompt to RestoreLoad default configuration now for the BIOS.
• Next, click on Yes and then follow the next on-screen instructions that appear to set the BIOS back to its default settings.
• Once you’re done restoring the default settings of the BIOS, restart your computer and then check if it now boots properly.

If you receive an error message saying, “Windows Update cannot currently check for updates because updates on this computer are controlled”, while trying to change the Windows Update preferences or manually update, then read on as this post will guide you in fixing it. You can mostly encounter this error in managed systems where an Administrator controls the permission on the operating system. The reason why you are not able to modify the Windows Update preferences or manually update your system is that a group policy prevents you from doing so and that the only user who can do these things is none other than the administrator of the system. Troubleshooting this kind of problem is the same as when you troubleshoot an error message that says, “Some settings are managed by your organization”. In such cases, you need to check both the Windows Update Group Policy and Registry settings. If you’re just a standard user, you have to contact your system administrator regarding this issue and if you are the administrator, you can make adjustments to the system settings via the Registry Editor and the Group Policy Editor. Refer to the instructions given below for detailed instructions.

Option 1 – via the Registry Editor

If you are using the Home edition of Windows 10 and you want to change the policy for non-admin users on your local computer, then you can use the Registry Editor for that. Here’s how you can do it:

• Tap the Win + R keys to open the Run dialog box.
• Then type “Regedit” in the field and hit Enter to open the Registry Editor.
• After that, navigate to the following registry key:

HKEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftWindows

• From there, look for the key named “WindowsUpdate” in the Windows folder and if it does not exist, you can just right-click on the Windows folder and select New > Key.
• Now name the new key “WindowsUpdate” and create a new sub-key under the newly created key and input “AU” as its name.
• Keep AU selected and then right-click anywhere in the right pane and select New > DWORD (32-bit) Value.
• Then name the Value as “AUOptions” and right-click on AUOptions and select Modify.
• Next, change the value of the Value data to “5” and click OK to save the changes made to the settings. Note that the Value Data of 5 refers to the policy to allow the local admin to choose the setting.
• Now restart your computer once you’re done and check if non-admin users can now modify the Windows Update settings or update Windows.

Option 2 – via Group Policy Editor

• Tap the Win + R keys to open the Run dialog box and then type “gpedit.msc” and hit Enter to open the Group Policy Editor.
• Next, navigate to this folder: Computer Configuration > Administrative Templates > Windows Components > Windows Update.
• Now look for the “Configure Automatic Updates” policy on the right pane and double click on it to open its Properties.
• After that, shift the Radio button to “Enabled” and from the drop-down menu for Configure automatic updating, select option 5: Allow local admin to choose the setting.
• Then click on Apply and OK to save the changes made to the settings.
• Restart your computer and check if the problem’s fixed or not.

One of the smoother things that Microsoft did with the Windows 10 operating system is to separate Cortana from Search. This means that Cortana is strictly now a voice assistant and many users have seen it coming since not everyone uses Cortana. In addition, it also paved the way for other virtual assistants like Alexa to get on board with Windows 10. And now in the newly released Windows 10 v1903, Windows has brought the Voice Activation under Privacy. In this post, you will be guided on how to perform the Voice Activation troubleshooting on your Windows 10 computer. To use Voice Activation in Windows 10, follow, in the Start Search, type “voice activation” and click on “Voice activation privacy settings” listed in the search results. And from there, you can choose to allow apps to use Microphone, like listen in the background as well as select which app can access it. Each time enabled voice assistants continue to listen via microphone for the voice keyword, the app will activate itself for the keyword and will react depending on what you ask it. So if you are using a voice assistant and it didn’t respond when you speak the keyword, just go to Settings > Privacy > Voice Activation and follow these steps:

Option 1: Check the App permission to use the voice activation feature.

You have to make sure that the toggle button for the Voice activation feature is turned on globally. It can be found under the “Allow apps to use voice activation” section. You also have to ensure that the microphone is available for apps that use this feature.

Option 2: Voice activation is not working under the lock screen.

If you tend to use the voice assistant even when your computer is locked, Microsoft has a specific setting that you have to turn on. You need to make sure that the toggle button for the “Allow apps to use voice activation when this device is locked” option is turned on. However, keep in mind that the voice assistants are not locked to only recognize your voice as they also answer to anyone who will use the voice keyword.

Option 3: Check the individual permissions of apps.

If the voice assistant is not working, you have to check each one of the apps’ permissions for voice keyword, and the option to work under locked condition works.

Option 4: Run the Microphone troubleshooter.

If you’ve verified that the settings are in place, then you have to run the Microphone troubleshooter by simply going to Settings > Privacy > Microphone. From there, make sure that the toggle button for the following options is turned on:

• Allow apps to access your microphone
• Enable microphone access for the voice assistant

And if it’s a desktop app, you have to enable the toggle on at the end.
