Taking information from the internet or from other sources usually involves selecting the text, copying it into the clipboard, and then pasting it into your file. In today's modern applications pasting text will most of the time take its formating with it.

By formatting what I am talking about are parameters like font size, line breaks, hyperlinks, font styles, etc. and sometimes you do not want any of these in your file, you would like and prefer to have just plain text so you can format it as you wish.

In order to paste just plain text instead of using the CTRL + V keyboard shortcut, press CTRL + SHIFT + V instead. This shortcut will paste the only text into your file.

Shortcut and Microsoft Word

Leave it to Microsoft to make its shortcut not work in their application. In Microsoft Word, you can only use the standard CTRL + V shortcut, if you press CTRL + SHIFT + V nothing will happen. So in order to paste the only text into a word document, choose to paste special > text only

Other applications

I have tried CTRL + SHIFT + V in various applications like photoshop, illustrator, InDesign, visual studio code, slack, discord, WordPress installations, etc and only one that has not worked for me was Word and office in general so you are safe to use this trick and have desired results.

Hello everyone and welcome to another tutorial on errortools.com, Windows itself when it is installed has a general idea about certain file types and how to open them, for example, image files would be opened with application photos, web links with the edge, etc. So when we double click on the known file type, Windows will start the default application for that type and open the file in it. But what if we do not want to open files in applications Microsoft thinks we should? What if we want to open the website in firefox or images in photoshop, or whatever. Luckily we can easily change which application Windows uses for which file type. Click on ⊞ WINDOWS to open the start menu and choose settings. On the settings screen, choose Apps. When the Apps screen opens on the left click on Default apps. On right, you will get a list of Windows default applications for certain types of files. Click on any application you would like to change and choose from the drop-down list a new one. Click on it and you are done.

I do not know about you, but I prefer to set my Windows to be more to my liking and not how Microsoft thinks it should be. Let’s face it, not all users feel comfortable whit Microsoft settings and idea how things should be. One of the things I particularly did not like even in Windows 10 is icons that come by default on my taskbar, now so far, well until the latest Windows 11 update you could remove default taskbar icons the same way as in Windows 10, just right-click on them and unpin, sadly with latest update build on Windows 11 this option has been removed. In order to remove default icons from the taskbar, one must go now to Windows 11 settings and choose from there which one you would like to be placed on it. Of course, this is nothing game-breaking but it still feels strange why the standard option has been removed, it just makes no sense but lately not many things that come from Microsoft do.

If you recently made some changes in your Windows 10 computer using the Group Policy Editor but they were not reflected and you got errors instead, it could be that your Windows computer wasn’t able to read the Group Policy file (registry.pol). To resolve this kind of issue, you have to repair the potentially corrupted Group Policy using the options given in this post. .As you know, Group Policy is a feature in the Microsoft Windows Active Directory which allows an admin to make changes in the features on Windows PCs that are on the network. So if the modifications you just made weren’t successfully applied, then there could be something wrong with the registry.pol file on the client or it could also be that the Group Policy folder is missing. To fix this issue in the Group Policy, you need to refer to the given suggestions below and make sure that you have admin privileges as you execute them.

Option 1 – Try to delete or recreate the missing registry.pol file

The entire settings of the Group Policy are stored in the registry.pol file so if it went missing, all the changes you make will not be reflected. The good thing is that you can recreate it but if the file exists and is corrupted, you need to delete it first before you recreate it.

• First, go to the C:/Windows/System32/GroupPolicy/Machine location.
• And from there, check if the registry.pol file exists or not. If it’s there, just delete it permanently by tapping the Shift + Delete keys.
• Now it’s time to recreate the file. Just open Windows PowerShell with admin privileges by tapping Win + X + A keys.
• After opening PowerShell, type this command: gpupdate /force
• The command you entered will recreate the registry.pol file and will refresh the Group Policy. Restart your computer.

Option 2 – Try recreating the secedit.sdb file

The security settings of Group Policy are stored in the secedit.sdb file so if you made some changes to security and they weren’t reflected, you can try to delete and recreate the secedit.sdb file instead of deleting the Group Policy file. All you have to do is navigate to the C:/WINDOWS/security/Database folder and look for the secedit.sdb file and rename it or move it to another folder. After that, restart your computer. Once your computer has restarted, the secedit.sdb file will be created again.

Option 3 – Try to reset the Group Policy to default

You can also try to reset the Group Policy back to its default state. There are several ways you can do that. You can either use the gpupdate or the secedit command in the Windows PowerShell to do that. Resetting the Group Policy will resolve any issues that could be caused by its current settings.

Option 4 – Try to perform System Restore

System Restore can also help resolve the Group Policy issue. It could be that prior to the issue, you’ve made some changes in the system that might have affected the Group Policy. To undo these changes, perform System Restore.

• First, tap the Win + R keys to open the Run dialog box.
• After that, type in “sysdm.cpl” in the field and tap Enter.
• Next, go to the System Protection tab then click the System Restore button. This will open a new window where you have to select your preferred System Restore point.
• After that, follow the on-screen instructions to finish the process and then restart your computer and check if the problem is fixed or not.

Option 5 – Use the DISM tool

You can also try running the Deployment Imaging and Servicing Management or DISM tool. This tool will repair the Windows System Image as well as the Windows Component Store in your Windows 10 computer. So if there are any missing or corrupted folders and files, the DISM tool can restore and repair them. As a result, any system consistencies and corruptions will be fixed. To run this tool, follow these steps:

• Tap the Win + X keys and click on the “Command Prompt (Admin)” option.
• After that, input each one of the commands listed below sequentially to execute them:
  • Dism /Online /Cleanup-Image /CheckHealth
  • Dism /Online /Cleanup-Image /ScanHealth
  • Dism /Online /Cleanup-Image /RestoreHealth

• Once you’ve executed the commands given above, restart your computer.

If you encounter an error saying, “error accessing the registry” when you try to merge a registry key on your Windows 10 computer, you’re not alone as some users also experienced the same problem. According to these users, they encounter the error after they’ve re-installed their Windows version and tried to open a .reg file. Based on the reports, this error could occur if the registry file does not have administrative privileges. Meaning to say, the program does not have the necessary permission to merge the .reg file. This is common with fresh installs as well as reinstalls. Moreover, this kind of issue could also occur due to system file corruption. Whichever the case may be, here are some troubleshooting tips you can check out to resolve the error.

Option 1 – Try to import the .reg file with admin privileges

As pointed out, the error may be due to a lack of admin privileges. It could be that the Registry Editor does not have admin privileges to merge the registry file. This is common with new Windows installations especially since the Registry Editor hasn’t been opened before. So you need to import the .reg file again and this time, with admin privileges.

• Tap the Win + R keys to open the Run dialog box.
• Then type “Regedit” in the field and tap the Ctrl + Shift + Enter keys to open the Registry Editor with admin privileges.
• A User Account Control or UAC prompt will appear where you have to click Yes to proceed.
• After opening the Registry Editor, go to File > Import using the ribbon bar at the top.
• Next, use the import menu to go to the location of the file you were trying to merge. Once you’ve found it, click Open to merge it with your current registry. This should fix the problem. If not, refer to the next options below.

Option 2 – Try performing a System Restore

Running System Restore can also help you fix the error when accessing the Registry. You can do this option either by booting into Safe Mode or in System Restore. If you are already in the Advanced Startup Options, just directly select System Restore and proceed with the next steps. And if you have just booted your PC into Safe Mode, refer to the steps below.

• Tap the Win + R keys to open the Run dialog box.
• After that, type in “sysdm.cpl” in the field and tap Enter.
• Next, go to the System Protection tab then click the System Restore button. This will open a new window where you have to select your preferred System Restore point.
• After that, follow the on-screen instructions to finish the process and then restart your computer and check if the problem is fixed or not.
• Once the next startup is complete, you have to merge or import the file again and see if the error is now fixed or not.

Option 3 – Try to perform repair install by creating a Windows 10 installation media

• Click this link and then click the Download Tool Now button.
• Next, click the “Use the tool to create installation media (USB flash drive, DVD, or ISO file)…” option and follow the next given instructions on the screen.
• Now select the ISO file option in step 5.
• After that, you should now have an ISO file.
• Next, go to the location where you’ve downloaded the ISO file.
• Then right-click on the Windows 10 ISO file and select the Open with option and then select File Explorer.
• Now click on “setup.exe” and follow the next instructions that appear on the screen. When asked, you have to select either Nothing (clean install) or Keep personal files only option. Take note that you must not select the “Keep personal files, apps, and Windows settings since it doesn’t really work.

Option 4 – Try running the System File Checker Scan

As mentioned, the error when accessing the Registry might be caused by file corruption. And that’s where the SFC scan comes in. The SFC or System File Checker scan could detect and automatically repair damaged system files. SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files with good system files. To run the SFC command, follow the steps given below.

• Tap Win + R to launch Run.
• Type in cmd in the field and tap Enter.
• After opening Command Prompt, type in sfc /scannow

The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

1. Windows Resource Protection did not find any integrity violations.
2. Windows Resource Protection found corrupt files and successfully repaired them.
3. Windows Resource Protection found corrupt files but was unable to fix some of them.

• Now restart your computer.

22H2 update for Windows 11 will arrive later this year and although Microsoft is not releasing anything big there will be some interesting improvements and fixes. We take a look at some that caught our attention.

Phishing protection

One of the most interesting upcoming features is enhanced phishing protection. Microsoft Defender SmartScreen will be upgraded to alert users when they try to store passwords in plain text files and also if they accidentally type in a Microsoft account password on phishing sites.

"These enhancements will make Windows the world's first operating system with phishing safeguards built directly into the platform and shipped out of the box to help users stay productive and secure without having to learn to be their own IT department,"

Microsoft

File Explorer gets tabs, a modern sidebar, and contextual suggestions

Finally, Windows File explorer is getting tabs that will allow much easier management of folders and files inside it.

It is confirmed that Microsoft is also working on a new 'HOME' sidebar that should be modern in design and in features including OneDrive so you can find everything in one place.

Pinning of favorite files was also mentioned so you can easily pin favorites for quick access.

Full-screen widgets

Windows 11 has brought back widgets in a new way and from all the feedback users are loving them. Currently, you have a widget sidebar on the left part of the screen where you have your chosen store widgets but from the Microsoft teaser, we will have soon the option to have them in full screen.

If you are using a widget for reading news, blogs, etc. this feature will be very good since you will be able to use your whole screen for information and not just a part of it.

Suggested actions

Another new feature is 'suggested actions' which is going to be particularly useful in apps like Microsoft Teams. With this new feature, you can highlight a date in a Teams message and Windows will suggest actions.

For example, if you highlight a date, you'll see a recommendation to create an event in Microsoft Calendar for that day.

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
