Fixing PowerShell: File cannot be loaded ...

There are a lot of home users that often get a computer that comes installed with the Windows 10 Home. And since Windows 10 Pro offers more features and utilities compared to Windows 10 Home, a lot of users also prefer to upgrade their Windows 10 Home computers to Windows 10 Pro. However, while doing so, a number of users reported that they encountered error 0xc03f6506 and they were not able to proceed with the upgrade. If you are one of these users, when you encounter error 0xc03f6506, you will see the following error message on your screen:

“The last product key you entered can’t be used on this copy of Windows (0xc03f6506).”

This particular error tends to occur when you go on to activate Windows 10 although it can also appear during the upgrade process. In such cases, you will see the following error message:

“Unable to upgrade your edition, We can’t upgrade your edition of Windows. Try upgrading your edition of Windows again. (0xc03f6506).”

To fix the Activation Error Code 0xc03f6506 in Windows 10, use the options provided below as references but before you proceed, make sure that you create a System Restore point first.

Option 1 – Try to use the Registry Editor

If you have already upgraded from Windows 10 Home to Windows 10 Pro and you’re having trouble with its Activation, then you might want to apply some registry tweaks to fix the problem. How? Refer to these steps:

• Tap the Win + R key combination to open the Run dialog box.
• Then type “Regedit” in the field and click OK or tap Enter to open the Registry Editor.

• After that, look for another DWORD named “ProductName” and double click on it to change its Value data to Windows 10 Professional.
• Once you’re done, restart your computer to apply the changes made successfully.

Option 2 – Try to use Command Prompt

If the registry tweaks you applied didn’t fix the Activation error, then you can try using Command Prompt instead. Note that you can use this option in both scenarios pointed out above.

• First, you have to insert a bootable drive of the Windows10 installer.
• Next, tap the Win + X keys and select Command Prompt (Admin) from the menu.
• After opening Command Prompt as admin, navigate to the root location of the bootable drive inside the Command Prompt command line.
• Once you’re already there, type the following command and tap Enter:

setup.exe /auto upgrade /pkey <YOUR WINDOWS 10 PRO EDITION PRODUCT KEY>

After entering the command, check if it was able to fix the Windows Upgrade or Activation error 0xc03f6506. If not, refer to the next given option below.

Option 3 – Try to disable the Network Adapter

Just like the second option, you can also use this option for both the given scenarios above.

• Tap the Win + X keys and select Network Connections from the menu.
• This will open the settings for your network and on the left side panel, click on the “Change adapter settings” link. This will open Control Panel.
• From there, click on the network your computer is connected to, and then right-click on the Network Adapter that you are using and select Disable.
• After disabling the Network Adapter, try to switch to the edition of your copy of Windows 10 again and see if the problem is now fixed and don’t forget to double click on the disabled Network Adapter to get back on the Network.

Error code 0Xc004F074 - What is it?

Did you previously use Windows 7 or 8 but decided to run with the latest Windows 0S, Windows 10? An early error message encountered was activation error code 0Xc004F074. Error code 0Xc004F074 is manifested when the user fails to activate Windows directly after the installation of Windows 10. This occurs if the previous operating system on your computer was Key Management Service (KMS) activated.

The KMT provides a more seamless operation when users are activating volume license editions of Microsoft Windows and Office. This process tends to be clear to end-users of the system.

Symptoms of error code 0Xc004F074 include:

• Windows is unable to reach your company’s activation service.
• The Key Management Service is unavailable.

Solution

Error Causes

Various factors might incite error code 0Xc004F074. A primary cause is a discrepancy or difference between the KMS client and the KMS host machine. The host computer could possibly be operating a Windows Server 2003 or Windows Server 2008, while the client runs on OS Windows 7 or Windows Server 2008 R2. To supplement, the computer’s time might be a contributing factor. The time on the host machine and client might show a difference (Usually the host time exceeds 4 hours).

Further Information and Manual Repair

To rectify error code 0Xc004F074, users are advised to try various methods. These methods include:

1. Method 1: Update Your KMS Host 9 (Windows Server 2003)

Are you running later versions of Windows Server? Use an update that fixes or installs KMS on your computer. The update is available on Microsoft’s website. Keep clearly in mind that the update is only for Windows Server 2013 Service Pack 1 and later versions of Windows Server 2003.

2. Method 2: Update Your KMS Host 9 (Windows Server 2008)

This step is similar to the aforementioned. However, it applies to Windows Vista and Windows Server 2008. This ensures the service is extended to Windows 7 and Windows Server 2008 R2.

3. Method 3: Update the Time

It was previously mentioned that the time reflected on the KMS host and client might cause error code 0Xc004F074 to manifest. A simple fix to adhere to is to always ensure that the time between both is updated. To Resync the time on the client, execute the following command.

w32tm /resync

4. Method 4: Uninstall the Existing KMS

For this method to be successfully deployed, you’ll need to have in your possession an activation key or KMSpico Key. As you cannot apply the new key with the existing one, remove or uninstall the initial key. To perform this step, open the command prompt. This should be done while the computer is in admin mode. Then, run the command

(slmgr.vbs /dlv)

It should be executed without the brackets and before you have removed the existing key.

After executing the command, you’ll encounter the description:

Windows(R) Operating System, VOLUME_KMS_WS12_R2 channel

Move along with the process by applying the slmgr.vbs /upk to uninstall the existing KMS key.

After the old key is uninstalled, you’re ready to apply the following:

slmgr.vbs /ipk <NewKMSProductKey>

To check if things are in place and complete the process, follow the steps below: PC Settings >Update and Security > Activation

5. Method 5: Download an Automated Tool

If you wish to always have at your disposal a utility tool to fix these Windows 8 and other related issues when they do arise, download and install a powerful automated tool.

Receiving a screen of death is not a pleasant experience at all and most users would agree that they would very much like not to face one during their work with the computer. Sadly PC is not a perfect machine and it is not working in a perfect environment so errors happen. The most famous and well-known death screen is blue which is also the most common one, my bet would be that there is not a user which has not been faced with this blue error screen. There is no simple explanation why these stop errors occur as several factors can be involved. However, it is known that the malfunctioning of hardware drivers or drivers that are installed by third-party software drive this unwanted change. But did you know that there is more colors for infamous death screens and not just blue one? Microsoft has coded different errors to different colors in the goal for the technical team to be aware right away of what type and kind of error they are dealing with. Color for screen errors are: Blue, Black, Pink, Brown, Yellow, Red, Orange, Green and White If you are interested in what color represents what keep reading.

BLUE

A stop error or exception error commonly called the blue screen of death (BSoD) or blue screen, is an error screen displayed on Windows computers following a fatal system error. It indicates a system crash, in which the operating system has reached a condition where it can no longer operate safely. This is caused by many different problems, such as a general hardware failure or a crucial process terminating unexpectedly.

---

BLACK

On Windows 10 systems, a Black Screen of Death can be caused by an unfinished Windows Update. To resolve this problem, simply hold the power button down on your PC or laptop to switch off the computer. A cold start should result in the system booting properly.

---

PINK

It is a diagnostic screen with a white type on a pink background. Pink Screen is mainly seen when the VMkernel of an ESX/ESXi host experiences a critical error, becomes inoperative, and terminates any virtual machines that are running. It is not fatal and generally considered more of a developer testing issue. When encountered, it can be fixed quickly by following the simple action of pressing and holding your computer’s power button to shut down the device.

---

BROWN

The Microsoft Windows 10 Operating System Brown Screen of Death is an on-screen fatal error notification with bug check codes which is seen when a computer crashes due to graphics hardware or software-related problems (failing graphics drivers).

---

YELLOW

It affects the functioning of a browser, particularly Mozilla Firefox. The Yellow Screen of Death makes the appearance with a weird buzzing sound in the background when the XML parser refuses to process an XML document causing a parsing error and a weird buzzing sound. The issue persists unless the computer is manually rebooted.

---

RED

Commonly the Windows 10 red screen is caused due to the hardware error, particularly if you overclock your Windows PC/laptop. Despite this, sometimes the red screen of death is also caused by outdated or incompatible drivers or due to BIOS issues.

---

ORANGE

The Orange Screen of Death on Windows occurs due to fatal hardware errors. Multiple reasons have been reported for the Orange Screen of Death. Some had this issue when watching a YouTube video, some were not able to boot into Windows. It can even occur when waking up from Sleep.

---

GREEN

The green screen of death only appears when you're running an Insider Preview version of Windows 10. It's the same as the blue screen of death, and it will show the same error messages. ... If you see a green screen of death (GSOD) on your PC, that's a sign you're using an Insider Preview build of Windows 10.

---

WHITE

The White Screen on Windows is also an error where the screen of the computer just turns white and freezes. There can be several things that can cause the white screen to appear on the Windows laptop monitor. But the main issue could be because of malfunctioning of the graphics hardware.

As you know, all computer mouse devices are designed ergonomically for users who are right-handed. Although that’s mostly the case, there are also other mouse devices that are designed specifically for left-handed users or the ones that can be used by either the right or left hand. But before you look for these kinds of mouse devices, there is actually an option you can try so that your mouse device can work with either the left or right hand. All you have to do is configure your mouse device. Aside from setting the device to work on either hand, you can also switch mouse buttons, from left to right, using only a couple of simple steps. As mentioned earlier, most mouse devices are created for right-handed users. Meaning to say, these mouse devices are configured to be right-handed with their primary button on the left and the second one on the right. The primary button is used for certain functions such as selecting and dragging. Now you can configure your mouse to be left-handed by swapping its predefined functionality. How? Refer to each one of the given instructions below.

Option 1 – via Control Panel

• Once you see it from the search results, click on it to open it and then go to the Hardware and Sound section.
• From there, click on Mouse under the Device and Printers section. This will open the window for Mouse Properties.
• Now you have to check the Switch primary and secondary buttons box.
• Then click on OK to save the changes made. After that, your primary select button on your mouse device is your right button while the secondary button, also known as right-click, is now the left button.

Option 2 – via Windows 10 Settings

This is the second option you can check out to change the configuration of your mouse from being right-handed to being left-handed.

• First, right-click on the Windows icon and select Search.
• Next, type “mouse” and from the search results that appear, click on Mouse Settings.
• After that, select “Right” from the “Select your primary button” drop-down menu. This should set the mouse device from being right-handed to being left-handed.

Google Chrome is the most used browser in the world with the most user downloads. Most users are using browsers how it is, open it up and just surf but Chrome offers more than just plain surfing. Here we are presenting you with some interesting features that most users do not use but should.

Use Omnibox to search inside websites

Chrome's Omnibox, also known as the address bar got its name because it can do much more than just search the internet. You already probably know that just by typing any word you will search the internet with Google or another search engine of choice.

Extensions

Using extensions in Chrome is awesome, specialy if extensions are usefull but if you go incognito they are not active. There is an option in Chrome to turn on the extensions even in incognito mode and even better, you can even choose which ones you want to be active, you do not need to turn all of them.

As you know, the Windows 10 operating system, as well as other Windows versions, comes with the Windows Firewall. In Windows 10, the firewall allows users to install and run a third-party firewall. This kind of firewall works independently to block any suspicious activity on your computer. However, recently, some users reported that they are getting a notification on the Startup saying,

“Windows Firewall and <Third party firewall name> Firewall are both turned off; tap or click to see available options”.

This particular error could be caused by a lot of factors but when you manually check the firewall, you’ll find that there really is nothing wrong with both the Windows Firewall and the third party firewall. So if both the Windows Firewall and third-party firewalls like McAfee, Comodo, and many others are both turned off in Windows 10, then you need to do several things to resolve the problem – you need to check the supporting services that are required and uninstall and then reinstall the third party firewall on your computer. For more instructions, refer to the options provided below.

Option 1 – Try enabling all the supporting services for the firewall

The first thing you can do to resolve the error with the firewall is to check all of its supporting services by following these steps:

• Tap the Win + R keys to open the Run utility and type “services.msc” in the field and then hit Enter to open the Windows Services Manager.
• Next, look for the Windows Defender Firewall service among the given list of services.
• Once you found it, make sure that its Startup Type is set to Automatic and that the status of the service is Running. So if it’s not running, just click on the Start button.
• In addition, you also have to make sure that the following services’ status is set as follows:
  • Xbox Live Networking Service: Manual
  • Base Filtering Engine: Automatic
• Once done, start the firewall again and check if the error is now fixed or not.

Option 2 – Try to uninstall and reinstall the third-party firewall

It is possible that the firewall error might be due to an error with the compatibility of the installation in Windows 10 and the third-party firewall. Thus, the next thing you can do is to uninstall the third-party firewall and then reinstall it again. Once you have uninstalled the third-party firewall, you can download its latest version from its official website and install it again. This should fix the error with the firewall.

In case you don’t know, new support has been added by Microsoft to Windows 10 that now allows users to turn off or on the Mobile Hotspot remotely. The Mobile Hotspot feature, known earlier as “Virtual Networks”, was first introduced with the initial release of Windows 10. With this new feature to remotely turn on or off the Mobile Hotspot in Windows 10, users can just use the Bluetooth on their mobile phones to turn off or on the Mobile Hotspot even when their Windows 10 computers are out of their reach. To turn off or on the Mobile Hotspot feature in your Windows 10 computer remotely, there are two options you can try. First, you can do it using the Windows 10 settings app or using the Registry Editor. To get started, refer to the following options.

Option 1 – Turn off or on the Mobile Hotspot remotely via Windows 10 Settings app

• First, you need to open the Windows 10 Settings app and from there go to Network & Internet and then go to the Mobile Hotspot section.
• After that, scroll down to the “Turn on remotely” section.
• Once done, make sure that the toggle button is set to ON and that the Bluetooth of both devices is turned on and paired as well. This should enable the feature to turn on or off the mobile hotspot remotely.

Option 2 – Turn off or on the Mobile Hotspot remotely via Registry Editor

Before you get started with the second option, make sure that you create a System Restore point first. Once done, proceed to the following steps:

• Tap the Win + R keys to open the Run dialog box and type “Regedit” in the field and then hit Enter to open the Registry Editor.
• Next, navigate to this registry path: ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWcmSvcTethering
• From there, look for the DWORD named “RemoteStartupDisabled” and set its Value data to be “0”. This will enable the feature that will allow you to remotely turn on or off the mobile hotspot in your Windows 10 computer. To disable it, just set its Value data to “1”.

If your USB keeps disconnecting and reconnecting after you connect your USB device on its own randomly, then the problem might have something to do with a hardware or driver issue. The first thing you have to do in such a case is to make sure that the device is working on another computer. This will help you isolate the problem and if it turns out that it works, then the problem lies in your computer and not your USB device. To fix this connection problem between your USB device and Windows 10 computer, you can use the options given below as a reference.

Option 1 – 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 and select the Update Driver from the menu.

Note: If it is a regular USB drive, then it will be listed as a USB Mass Storage Device but if you have a USB 3.0 device, then look for a USB 3.0 Extensible Host Controller.

• 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 2 – Try to change the USB port

You might want to change the USB port since modern computers have a variety of USB ports. So if your USB drive supports USB 3.0 or 3.1, make sure that you plug it inside a USB 3.0 or 3.1 ports. If you’re not sure which port, just keep in mind that the USB 3 port is usually blue or you can also use your computer’s documentation or manual as a reference to locate it.

Option 3 – Try to turn off the Power Saving option

You could also try to turn off the Power Saving option to resolve the problem. All you have to do is switch to Power Management after you select the Properties of the USB device and from there, uncheck the “Allow the computer to turn off the device to save power” option. On the other hand, if you are using a laptop and did not use the USB device for a long time, then it could be powered off. This will ensure that the system does not turn off the USB device.

Option 4 – Try to reinstall the latest Universal Serial Bus controller drivers in Compatibility Mode

If you were unable to install the Universal Serial Bus controller drivers you’ve downloaded, you can try installing them again but this time using Compatibility mode. Follow the steps below to do so:

• You need to download the driver and place it on your desktop.
• After that, right-click on it and select Properties.
• Next, switch to the Compatibility tab where you should see two options:
  • Compatibility troubleshooter, and let Windows figure out what works best for you. If it fails, follow the next.
  • Manually choose the version of Windows it was correctly working.
• Now right-click on the file and select the “Run as administrator” option to install. After that, you should now be able to change your screen aspect ratio to what you were using early on.

Note: If you have other programs that won’t work on the existing version of Windows, then make sure to run the program in a Compatibility mode.

Option 5 – Run the Hardware and Devices Troubleshooters

• 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.

Roblox is a very popular online game with millions of gamers playing it each day and as such it will naturally bring a lot of malware and attack on players trying to steal and exploit them for monetary gains. The latest attack and high-profile stealing of currency and assets happened exactly in Roblox.

Malicious activities have been reported to come from chrome extensions. So far 2 extensions have been identified that have hidden malware inside them but there could be more of them currently undetected. Extensions work as a front while in the back they mine user logins and other data in order to steal stuff from the Roblox platform.

To make things worse some of the malware is within long extensions like SearchBlox. The SearchBlox extension allows you to search quickly for other users if it was legitimate but has been compromised within the last month. There is evidence that people are stealing Roblox currency with the data gathered by the hidden backdoor in it.

SearchBlox extension is still Active in Chrome Web Store, with the primary listing still with the "Featured " badge. Google is actively removing malicious software from its storefront on a regular basis but this one still lingers in it.

If you or your kid have this Chrome extension installed, uninstall it right away and always be careful about which extension you install and give access to your system, keep them updated and check various blogs and article sites to inform yourself when a bad one is found.
