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.

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.

Microsoft is trying to make Windows into a personalized OS, more and more features and parts can be customized to user liking. From larger things to smaller ones nowadays you can almost personalize every detail of Windows itself. In this article, we will tackle how to bring back the names of running applications on the taskbar. Placing names beside icons on the taskbar is a pretty simple and straightforward task easily done. First, right-click the Taskbar and select Taskbar settings. In Taskbar settings, click the menu labeled Combine taskbar buttons. Select Never. That's it, now all of your running applications have a name beside them. If you change your mind, you can always undo it by selecting Always hide labels in the Combine taskbar buttons menu.

Like in Windows 10, Windows 11 will also support God mode to be enabled and used. For those readers that do know what God mode is, let me explain it in simple terms. God mode is the icon on the desktop that once clicked will open and let you adjust every option in the control panel and some hidden features for Windows inside one application. There are a lot of advantages to having this one-click fast access to features, especially if you are a power user. Luckily creating such an awesome icon and enabling God mode is very easy to accomplish, all you have to do is:

1. Create a new folder where you want to have the God mode icon
2. Rename folder exactly: {ED7BA470-8E54-465E-825C-99712043E01C}
3. Enjoy God mode

As you can see creating and accessing all settings at your fingertips is much easier than most people think. Enjoy your ultimate access to Windows 11 features and if you wish you can drag and drop sections from it into the desktop or anywhere for easy access to that specific topic.

If you are browsing the web but suddenly encountered the ERR_BLOCKED_BY_CLIENT error on your Chrome browser in Windows 10, read on as this post will guide you in fixing this problem. This kind of error has already been reported by a number of Chrome users and it seems that the problem has something to do with a plugin or extension. Here’s the exact content of the error:

“This webpage was blocked by an extension (ERR_BLOCKED_BY_CLIENT)”

This kind of error, as pointed out, could be caused by an extension or plugin on Chrome that is blocking the web page. It is also possible that the version of Chrome is obsolete or that there could be more than 100 bookmarks in the Bookmark Manager. Before you troubleshoot the problem, make sure that you download the latest version of Google Chrome and see if it fixes the error.

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

As you know, storage devices are an important part of the computer system for porting, saving, and extracting data files. And for you to differentiate between storage devices on your computer system, each one of the storage devices is labeled with a unique number referred to as Disk Signature for identification. The unique disk identifier is stored as a part of the MBR or Master Boot Record. Disk signature is used by operating systems in order to identify and set apart different data storage devices and hard disk drives in the computer for data access. These days, Disk cloning has become a regular practice in upgrading to larger hard disk drives. Drives are cloned in order to produce a similar copy to use both the original drive and cloned copy together. Moreover, lots of virtualization tools are being used to virtualize the physical hard disk drives to create virtual hard disk drives and several virtual machine clones that are created with the existing virtual hard disk drives. And since these are identical copies, chances these copies may have identical disk signatures. As a result, when you use both disks that have identical signatures at the same time you run into the Disk Signature Collision problem. This kind of problem does not often occur as the Windows system does not really allow two disks to function simultaneously when they have the same disk signature. When you encounter a Disk Collision problem in your Windows 10 computer, you may see the following error messages:

• The boot selection failed because a required device is inaccessible
• The disk is offline because it has a signature collision
• This disk is offline because it has a signature collision with another disk that is online

You can fix the disk collision problem by changing the disk signature which you can achieve using the command line utility diskpart in Windows PowerShell or Command Prompt or using Windows Disk Management utility. To fix the disk collision problem, you can make use of the command-line utility called diskpart in Windows PowerShell or Command Prompt to view and change the signature, or can make use of Master Boot record in the Windows Registry. You can also make use of Windows Disk Management Utility to change the signature. Simply follow the given options below to change the disk signature either way.

Option 1 – Change Disk Signature via Diskpart

• Type “command prompt” in the Windows Search bar and then right-click on the related search result and select the “Run as administrator” option.
• After that, type the “diskpart” command and hit Enter to open Diskpart.
• Next, type the “list disk” command to display all the disks available in the system.
• Next, take note of the problematic disk number with the status Offline from the list and then type the “Select disk x” command where x is the offline disk to select the offline disk. For instance, if you type “select disk 1”, it will display the “Disk 1 is now the selected disk” message.
• Now type the “Uniqueid disk” command to display the disk signature and to change the disk’s signature and set the disk online, type the “unique disk ID= (New signature)” where (New signature) is the new ID in hexadecimal. For instance, you can set the new id as “unique disk ID= 1456ACBD”.

Note: If you have given the wrong format ID, the command prompt will display the following error:

“The specified identifier is not in the correct format. Type the identifier in the correct format: in hexadecimal form for an MBR disk or as a GUID for a GPT disk.”

• After you’re done, the disk will be online, and then restart your computer.

Option 2 – Change Disk Signature via Disk Management Utility

• Tap the Win + R keys to open the Run dialog box and then type “diskmgmt.msc” and hit Enter or click OK to open Disk Management.
• Next, right-click on the disk that is marked as Missing or Offline.
• After that, select the Online command from the drop-down menu.
• Then from the selecting option Online, Windows will generate a new disk signature.

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.

One of the worst problems users can encounter on their computers is Blue Screen of Death errors as some of them are quite hard to fix. One of them is the “The driver detected a controller error” Blue Screen error. It could be followed by “DeviceIdeIdeport0 OR”, “on deviceharddisk0dr0”, or “DR3” or the name of the drive or port that’s causing the problem. If you are one of the users who encountered this error, then the suggestions provided in this post would definitely help you in fixing the problem.

Option 1 – Try to disconnect and reconnect all hardware and cables

A lot of users reported that they were able to fix the problem by disconnecting and reconnecting cables and hardware like scanners, printers, cameras can help in fixing the problem. In addition, you can also boot your computer in a Clean Boot State so that you can find the problematic hardware by hit and trial method. Refer to the steps below to do so:

• Log onto your PC as an administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.
• From there, go to the General tab and click “Selective startup”.
• Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
• Next, click the Services tab and select the “Hide All Microsoft Services” check box.
• Click Disable all.
• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)

Option 2 – Update the device drivers

Updating the outdated device drivers in your computer can also help in fixing the problem. To do so, refer to these steps:

• First, boot your computer into Safe Mode.
• After that, tap the Win + R keys to launch Run.

• After that, right-click on each entry of the device drivers and select the “Uninstall Device” option from the menu.
• Now restart your computer.
• After restarting your computer, go to the Settings app and Check for Updates in the Windows Update section.

Option 3 – Try to update the BIOS

Updating the BIOS can help you fix the ATTEMPTED_WRITE_TO_READONLY_MEMORY BSOD 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 4 – Try running the Blue Screen Troubleshooter

You might also want to run the Blue Screen troubleshooter. It is one of the built-in tools in Windows 10 that helps users in fixing system issues including Blue Screen errors. It can be found in the Settings Troubleshooters page. To use it, refer to these steps:

• Tap the Win + I keys to open the Settings panel.
• Then go to Update & Security > Troubleshoot.
• From there, look for the option called “Blue Screen” on your right-hand side and then click the “Run the troubleshooter” button to run the Blue Screen Troubleshooter and then follow the next on-screen options. Note that you might have to boot your PC into Safe Mode.

Option 5 – Try running the Memory Diagnostic Tool

The Memory Diagnostic tool in windows can help resolve the “The driver detected a controller error” Blue Screen error by checking and automatically fixing any memory-based issues. To run it, refer to these steps:

• Tap the Win + R keys to open Run and type mdsched.exe and hit Enter to open the Windows Memory Diagnostic Tool.
• After that, it will give two options such as:
  • Restart now and check for problems (Recommended)
  • Check for problems the next time I start my computer
• Once your computer has restarted, perform a basic scan or you could also go for the “Advanced” options such as “Test mix” or “Pass count”. Simply tap the F10 key to start the test.

Note: After you select your preferred option, your computer will restart and check for memory-based issues. If it finds any issues, it will automatically fix them and if there’s no issue found, then it’s most likely not a memory-based issue so you should try the other options given below.

Option 6 – Replace your motherboard

If your computer is still under warranty, you should consider replacing your computer’s motherboard in case the options given above failed to work in fixing the Blue Screen error.
