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.
• Next, navigate to this registry key: ComputerHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersion
• From there, look for a DWORD named “EditionID” and once you found it, double click on it and change its Value data to Windows 10 Professional.
• 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.

As you know, the USB security keys are a secure medium to validate a lot of components in a computer. They can be used to log in to Windows 10. Now with the advancement of APIs, you can authenticate across the website as well using the same key. However, there are times when it may not work and it could be caused by several factors. It could be due to corrupted or incompatible drivers or it could also be due to compromised integrity of the key, and many more. So if you happen to encounter an issue with the USB security key on your Windows 10 computer, then there are several potential fixes you can try. You can try toggling the Internet Options settings or reinstall the respective USB drivers. You could also try changing the PIN of the security key or disable the antivirus program on your computer or troubleshoot the web browser. Refer to the potential fixes provided below to fix the problem.

Option 1 – Try to toggle the settings of the Internet Options

• In the Windows Search box, search for Internet Options to open it.
• Next, go to the Security tab and drag the security slider to the lowest possible security for all the given zones.
• After that, click on OK to save the changes made and close the Internet Options.

Note that this option is only a temporary measure as it can make your computer vulnerable. Make sure to press the Reset all zones to default level button.

Option 2 – Try to update or reinstall the respective drivers

If updating the drivers of the device did not fix the problem with the USB security key, you can try to update or reinstall the Universal Serial Bus Controller drivers instead of 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 3 – Try to change the PIN of the security key

If the first two options didn’t work, you can try changing the PIN of the security key. There are instances when the PIN for the security key might have been corrupted. Thus, resetting it can help you resolve the problem.

Option 4 – Temporarily disable Firewall and third-party antivirus

Firewall and antivirus programs are known to block the proper functioning of the USB security key. Thus, your antivirus or firewall programs might be the reason why you can’t download anything on your Windows 10 computer. To isolate the issue, you need to temporarily disable both the Firewall and antivirus programs and then check if you can now download anything from the internet. Do not forget to enable them again as disabling them can leave your computer vulnerable to cyber threats.

Option 5 – Try to troubleshoot the web browser

Troubleshooting your web browser can also help you fix the USB security key problem. You can do that by checking if your web browser supports the security key and you can do that by checking on the official website of your browser. You can also try to update your web browser to its latest version but if it didn’t help, you can try to reinstall it or switch to another web browser.

A lot of Windows 10 users prefer the black theme on their computers and when you see anything but black it can get quite annoying. Such as is the case of the Taskbar which, as you know, is usually dark, however, when you take a look at the Cortana search bar, instead of seeing black, you’ll see that it has turned white. To fix this issue, read on as we will provide you some options you can try to set the Cortana search bar back to black. Before you proceed, take note that the options provided below will change all white search boxes to black and that one of these options needs administrative privileges.

Option 1 – Try changing the default App mode

As you know, Windows 10 has two modes, namely the Light and the Dark. Thus, you can switch to the Dark mode so that your Cortana search bar will be black as well. However, remember that it will completely change everything into dark mode so there will be no more Light mode elsewhere.

• First, you need to click on the Start button and then click on the cog icon to open the Windows 10 Settings.
• Next, from the Settings Menu, select Personalization and then select Colours from the left pane.
• Then scroll down until you see the “Choose your default app mode” option and select “Dark”.

After you apply the changes, it will change the Cortana search bar into black instantly. Aside from that, you will also see the User Interface changing into dark mode.

Option 2 – Try changing the Registry value

If you are well-versed in editing registry keys, then you need to try this option. But before you go over the steps below, make sure that you create a System Restore point first so that if anything goes wrong, you can always go back to how it was before the changes were applied.

• Tap the Win + R keys to open the Run prompt.
• Then in the field, type in “regedit” and hit Enter to open the Registry Editor. If a User Account Control prompt appears, just click Yes.
• Now that you’ve opened the Registry Editor, navigate to the following key:

HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionSearchFlightingWhiteSearchBox

• After that, double-click on the “Value” key located on the right pane and set the value to “0” instead of “1” and then click Ok to save the changes made. You should now see a black or grey text box color instead of white.

Option 3 – Try changing the Region

In some forums, a lot of users stated that changing the Region also worked out for them in changing the white Cortana search bar to white. Thus, you need to change the region settings of your computer temporarily. To do so, follow the steps below.

• Type in “Regional Settings” in the box and then click it as soon as it appears from the search results.
• Next, make sure to select a region where Cortana is not available.
• Then select apply to that region. After that, it will change the Cortana search bar color to black.
• Now sign out and sign back in and revert to the original settings. But the changes you made earlier in Cortana will still remain.

Error 0xc0000225 is the error that occurs on system startup, most times error just disappears all by itself but in some cases, it can be really persistent and can even cause you not to be able to enter the system that could be a really annoying thing, especially if there is some important task waiting to be finished. In this guide, we will present you with solutions for this error and how to solve it so you can get back to work as soon as possible.

Solution if you can not log into windows due to repeating error

If an error repeats itself constantly and you are unable to boot into Windows itself you will need to prepare Windows boot USB. You can download the Microsoft media creation tool here and then use it to create a bootable USB with Windows 10. Once the USB is done reboot your system and boot from USB. CHoose repair Windows instead of install and follow onscreen instructions.

Solution if you can log into Windows

If you can log into Windows bring up the command prompt in administrator mode and type in it SFC /SCANNOW followed by ENTER, wait for the whole operation to finish, and then reboot the system.

Windows 11 has arrived and it is being adopted all around the globe as we are writing this article. People are adapting it daily and today we will take a look at some advanced security features of the new Windows and do you really need an antivirus in it. It is not a secret that Windows 11 is the most secure Windows ever created, well at least up until now. It is packed with advanced security features like S-mode, Secure Boot, and Trusted Platform Module (TMP 2.0). All these new security features that Microsoft has advertised made people question are enough for security or do you still need third-party Antivirus software. In order to get an answer to this question, let us first take a detailed look at what each one of them does, and then we will give you our opinion on a given subject.

Windows S mode

For everyday home use, Windows 11 S mode is the most secure feature to have on your PC. This is a safety protocol where only apps from Microsoft Store are allowed to be installed. This eliminates the risk of installing third-party apps that may contain viruses or malware. Furthermore, S-mode protects your web browsing activity through the Microsoft Edge browser. S-mode does not allow you to use other browsers for security reasons. If you are using Windows 11 in S-mode, your PC and data will be secure in most parts. You need not buy antivirus when using Windows 11 in S-mode.

Windows Defender

The inbuilt security suite, Windows Defender was launched for the first time in 2006. Earlier to that it had existed and was known as Microsoft AntiSpyWare. Windows Defender has undergone significant improvements over the years. In its latest version available with Windows 11, Windows Defender offers a comprehensive range of security features. It is available under the Windows Security system. Some key security features include real-time virus and threat protection, account protection, firewall & network protection, app and browser control, parental controls, and device (hardware) security. This is comparable to security features offered by third-party antivirus programs.

Microsoft Account

In Windows 11, it is necessary to use a Microsoft account that will be linked to your device. This ensures the security of your data in case your device is lost or stolen. You just need to make sure that you have set a strong password for your device. Windows 11 also has Bitlocker that keeps your data in encrypted form.

Ransomware protection

In view of rising cases of ransomware, Microsoft has introduced dedicated ransomware protection in Windows 11. It works by stopping apps from carrying out unauthorized changes to files and folders. Users can choose their important files and folders that they want to be protected from ransomware.

Conclusion

As we went through Windows 11 security features, we can clearly see that it is packed heavily with many security features that aim to protect your data and your identity. Looking at them, one can clearly come to the conclusion that you do not really need any third-party software and that Windows itself can catch and protect most of the issues, and they would be right. If you use Windows 11 carefully, meaning that you go only to trusted websites, do not open suspicious emails, and click on suspicious links, if you do not use extensively external USB devices or mass media you really do not need any kind of third party protection, Windows built-in tools will do well and keep you protected. However, if you do come in contact with other people's USB devices if you surf over the net, and overall if you really want to be at peace of mind that you are protected you will still need a well-established third-party software protection solution. Windows 11 has great security features, best so far in any Windows but it is still far from being a solution that does not require dedicated protection solution. So do yourself a favor and grab one. We recently had a top antivirus software review, find the article here and pick one that is best for you. https://errortools.com/viruses/the-best-antivirus-software-of-2021/

Windows 11 comes with glass and transparency effects by default once it is installed. The transparency effect looks really good but if in any case, you do not like them, you can easily turn them off very easily

1. Open settings inside Windows 11
2. Inside settings click on Accessibility in the sidebar
3. Click on Visual Effects on far-right
4. Inside Visual effects, settings click on the switch beside Transparency effects to OFF

Windows will automatically save settings and apply changes right away. Just close your settings application and continue with work. You can always turn it back ON if you change your mind.

One of the cool and interesting features in Windows is the Screensaver which allows users to display animation or change the wallpaper automatically when the computer is not being used. This feature can also time out and lock your computer when it remains idle for quite some time. However, if you notice that the screensaver of your computer turns on a lot earlier, then you’ve come to the right place as this post will guide you on how you can change the timeout settings of the screensaver of your Windows 10 computer. Usually, the screensaver in Windows 10 is turned off by default, however, if some other user has turned it on or if you have turned it on, you can actually change the timeout settings of the screensaver using several methods. You can do it through the Personalization settings, Registry Editor, as well as the Group Policy Editor. Before you proceed with the instructions provided below, make sure that you create a System Restore point first. Once done, follow each one of the suggestions carefully to successfully change the Screensaver timeout settings in Windows 10.

Option 1 – Modify the timeout settings of Screensaver via Personalization settings

• Open the Start menu and type “screen saver” in the field.
• On the search results that appear, click on the “Change Screen Saver” option.
• From there, you have the option to change the screen saver type, preview, open settings, change the wait time, as well as choose to display lock screen on your resume.
• Now to change the timeout settings of your screensaver, you have to increase the wait time from 1 to 15 or anything that works for you.
• Once done, click OK and exit to save the changes made.

Option 2 – Try to change the screensaver time via Registry Editor

The next option you can try to change the timeout settings in the screensaver is using the Registry Editor. To get started, follow these steps:

• Tap the Win + R keys to launch the Run utility and type “regedit” in the field and hit Enter to open the Registry Editor.
• Next, navigate to this registry path: ComputerHKEY_CURRENT_USERSoftwarePoliciesMicrosoftWindows
• From there, right-click on Windows located in the right pane and select New > Key.
• Name the key as “Control Panel” and right-click on it and select New > Key and then name it as “Desktop”.
• Once done, click on the newly created Desktop key to highlight it.
• After that, right-click on any empty space in the right pane and select New > String Value and then type “ScreenSaveTimeOut” and hit Enter to save it.
• Now right-click on ScreenSaveTimeOut and select Modify and then set its value data in seconds.
• Click on OK and exit the Registry Editor to save the changes made.

Option 3 – Change Screensaver timeout settings via Group Policy Editor

• Tap the Win + R keys to open the Run dialog box and type “gpedit.msc” in the field and hit Enter to open the Group Policy Editor.
• Next, navigate to User Configuration > Administrative Templates > Control Panel > Personalization.
• Then look for a policy setting named “Screen saver timeout” and double click on it and then click on the Enabled option to enable it.
• Add the screen timeout in seconds and click on the Apply and OK buttons to save the changes.
• Restart your computer.

Note: If you want to disable the screensaver feature in your computer, you can always do so by disabling a policy setting named “Enable Screen Saver”.

As you know, Windows 10 comes with the option to create Mobile Hotspot for other devices. This allows you to share your Ethernet connection. However, there are times when one of your devices might fail to reconnect to the mobile hotspot again. For instance, you moved out of the Wi-Fi range because you have somewhere to be and whatnot and when you’re back you find that you are now unable to reconnect to the Windows 10 Hotspot or the shared network. Although you can always restart the mobile hotspot to resolve the problem, however, it might only be a temporary fix. So in this post, you will be given options for a much better solution to the problem. This kind of problem seems unusual and does not occur that often. To fix it, you can try to set up DNS on your Windows 10 device and then configure the settings on the mobile device. It seems that what’s happening here is that the mobile device is unable to lock on to the Mobile Hotspot when the IP address changes for some reason.

Option 1 – Try changing the DNS settings on your laptop

In this option, you need to make sure that IPv4 and IPv6 are selected on your Ethernet connection. You also have to change the Preferred DNS server as well as the Alternate DNS server to 8.8.8.8 and 8.8.4.4, respectively. You also have to validate the settings before you exit just to ensure that you’ve entered everything correctly. After that, open Command Prompt and run the ipconfig command and then take note of the IP address, Gateway DNS 1 and DNS 2.

Option 2 – Try changing the Wi-Fi settings on your mobile device

This option should be mostly the same on all your mobile devices. And given that OEMs build their customization and skin, you might have to fiddle around a little to get the settings. Refer to the steps below to change the Wi-Fi settings:

• Go to the Settings of your mobile device and tap on Wi-Fi.
• Then click the Mobile Hotspot connection that you’ve created on your laptop.
• After that, input the password and tap the Advanced options.
• From there, tap on IP settings and select the Static option instead of DHCP.
• Now you have to enter the IP address, Gateway, DNS 1, and DNS 2 of the laptop you’ve taken note of earlier and that’s it.

Note: If you are already connected to the Mobile Hotspot, long press on the Wi-Fi network and select the Modify Network option and then follow the steps given above to change from DHCP to static. Once you’re done, your mobile device should now be able to connect to the Windows 10 Mobile Hotspot all the time.

Stable Diffusion is a machine learning model developed by Stability AI to generate digital images from natural language descriptions. The model can be used for different tasks like generating image-to-image translations guided by text prompts and upscaling images.

Unlike competing models like DALL-E, Stable Diffusion is open source and does not artificially limit the images it produces. Stable diffusion was trained on a subset of the LAION-Aesthetics V2 data set. It can run on most consumer hardware equipped with a modest GPU and was hailed by PC World as "the next killer app for your PC".

Since Stable Diffusion is run locally and not in the cloud, as mentioned there is no limit to the number of images that you can produce but in order to use it you will have to get down a little dirty with setting your PC environment for it since it is not really an application, it is a command line text based descriptor that will use python to generate your images, so there is no install nor GUI.

In this guide, we will show you how to both install and run Stable Diffusion on your local PC so you can start producing some cool images all by yourself.

Hardware and software requirements

Make no mistake, Stable Diffusion will not run on a potato PC, in order to harvest the power of AI-generated imagery this is what you will need:

• A GPU with at least 4GB of VRAM
• 10GB of hard disk space
• Python and libraries (Miniconda3 installer will install everything you need)
• The Stable Diffusion files
• Git
• Any OS (Windows, Linux, macOS)

Installing components

For this tutorial, we are covering the installation and running of Stable Diffusion on Windows PC. The steps presented here are presented in a way that installation can be performed on any operating system but precise instructions will be for Windows OS.

GIT

The first thing to do is to install GIT. It is a tool that will let you easily maintain and install repos from the internet. to install it go to: https://git-scm.com/ and click on download. Follow the instructions for your version of the operating system. If you are a developer you are familiar with GIT and if you already have it installed you can skip this step.

One thing that is important when installing GIT locally is to select to use it via the command line (the second option that says "Git from the command line and also from 3rd-party software").

Miniconda3

Now when we have GIT installed, next thing is to use Miniconda3 to install python and all required libraries that are needed. Get the installer at: https://docs.conda.io/en/latest/miniconda.html

Miniconda3 is basically an easy installer so you do not have to install tons of stuff manually from different websites and sources, it is nicely packaged in the installer that will take care of everything.

Stable Diffusion

After the previous two steps, we are ready now to actually install Stable Diffusion. Go to https://huggingface.co/CompVis/stable-diffusion#model-access and install the latest library (as of the writing of this article currently it is stable-diffusion-v1-4-original, the last one on the right), the library is almost 5GB in size so be prepared for big download.

After installing stable diffusion's latest library it is time to update it to the newest version. You can download ZIP from GIT HUB https://github.com/CompVis/stable-diffusion

Once downloaded click on the Windows start button and type in Miniconda3 and click on open. Create a folder and name it how you want on a drive of your choice. For this example, we will install it all in disk C under folder AI_art, follow the instructions below but use your own names and destination instead. Do not close Minicoda3 after typing commands!!!

cd c:/
mkdir AI_art
cd AI_art 

Extract GitHub files that you have downloaded into your new folder and get back to Minicoda3 and type the next commands:

cd C:\AI_art\stable-diffusion-main
conda env create -f environment.yaml
conda activate ldm
mkdir models\ldm\stable-diffusion-v1

Let the whole process finish, some files are large and it might take a while. After the whole process is finished and completed, copy the checkpoint file that you have downloaded into: C:\AI_art\stable-diffusion-main\models\ldm\stable-diffusion-v1

After the file is copied rename it to model.ckpt and you are finished.

Running Stable Diffusion

The created environment is needed in order to actually use Stable Diffusion to create images. Each time you want to use it you will have to run it, so go into Miniconda3, and inside it type:

conda activate ldm
cd C:\AI_art\stable-diffusion-main

after we are inside the folder call the script with the parameters:

python scripts/txt2img.py --prompt "TXT DESCRIPTION OF IMAGE THAT YOU WANT TO CREATE" --plms --n_iter 5 --n_samples 1

and that's it, your image is created and it is located in C:\AI_art\stable-diffusion-main\outputs\txt2img-samples\samples
