Windows 10 and Windows 11 have automatic dynamic screen brightness depending on the surrounding light inside the room. Please take note that this option is available only on devices with build-in screens like laptops, tablets, and all in one desktop PC. If you are connected with your PC via an external monitor you will not have these settings available and probably feature is not even working.

Some computers will also allow automatic brightness changes also on what is displayed on the screen. This option is meant to save battery life on devices. Microsoft calls this automatic brightness feature Content adaptive brightness control. In order to change this setting, we will go to settings inside Windows.

Disabling automatic brightness inside Windows

Open Settings inside Windows, in Windows 11 press WINDOWS + I to open settings, then click on the system in the sidebar and then go to Display. Click on the small arrow beside the Brightness slider in order to expand a small menu and then uncheck Help improve battery by optimizing the content show and brightness. If you see Change brightness automatically when lighting changes, uncheck that as well. Close the settings and you are good to go, now brightness will always be as set in settings.

Inside Windows 10, go to Settings and then go to System and then in Display under the Brightness and Color section look below and locate the box that says Automatically adjust contrast based on the displayed content to help improve battery and uncheck it, if the box below with text Change brightness automatically when lighting changes exists, uncheck it as well. Close settings and you are done.

Microsoft allows its users to download a copy of Windows to install on PCs. However, when you enter the key after the installation and you got the Activation Error 0xC004F212 instead, then it means that the license key and the Windows version you’ve just installed, do not match. When you encounter this error, you will see the following error message on your screen:

“The product key used on this PC didn’t work with this edition of Windows. Activation Error 0xC004F212.”

Every time Microsoft generates a license for a copy of Windows, it is associated with one particular Windows variant. Windows comes in many editions like Enterprise, Home, Professional, and so on. For instance, if you bought a license for Windows 10 Enterprise but you have installed Windows 10 Professional instead, then the activation will surely fail and you’ll encounter the Activation Error 0xC004F212. You will be asked to select which edition you want to install when you reinstall Windows 10 using a digital license. If you opted for an edition other than the one you are licensed to use, then you will most likely get the Activation Error 0xC004F212. If you have purchased your license key from a store or some website, you might want to check back with them about the exact version of Windows. Doing so will help you narrow down the problem. And if you have second thoughts about the license key’s validity, you can just reach out to a Microsoft Support agent to check the validity of the license key. Also, if have bought it from the store, there should be an option to get a refund. That way you can choose to buy the right version of Windows.

Option 1 – Try running the Windows 10 Activation Troubleshooter

The first thing you can do to resolve the Activation Error 0xC004F212 is to run the Windows 10 Activation Troubleshooter. To do so, follow these steps:

• Go to Settings and then select Activation.
• After that, click on the Windows Activation and then troubleshoot. This will help you address most of the commonly found activation issues in Windows devices.

The Windows 10 Activation Troubleshooter will determine if your license key is a valid Windows 10 digital license for an edition that is not currently installed. If it turns out that it’s not, then the troubleshooter will show you how to install the correct edition.

Option 2 – Try forcing Windows 10 ISO to use the right version

You can also try to force Windows 10 ISO to use the correct version depending on the product key. Note that this option only works between Windows 10 Home and Professional version since they both have a common ISO. So if it’s Enterprise, then this option won’t work for you.

• Extract the Windows 10 ISO files using an extractor.
• Then browse to the folder you created and go to the sources folder.
• From there, you need to create a text file named “PID.txt” and make sure to follow the exact format given below:

[PID] Value=xxxxx-xxxxx-xxxxx-xxxxx-xxxxx

Note: “xxxxx” is the KEY to your Windows version.

• Next, you need to create the ISO again or bootable media that will repack everything and then create the Media file. You can use the Media Creation tool for this.

Note: Windows will check the key during the installation and will figure out the right version of Windows.

Option 3 – Contact Microsoft Support for assistance

If you’re at your wits’ end in trying to update your Windows 10 computer, you should consider contacting Microsoft Support for help as they can offer you various options that would make fixing Windows Activation Error 0xC004F212 a lot easier and faster.

It is common to run multiple programs and applications at the same time and it’s important to be able to switch between them using their Taskbar icons or using the usual Alt + Tab shortcut. However, there are times when you might suddenly find that neither of the aforementioned methods worked and you will no longer be able to switch between programs in the Windows Taskbar. To fix this issue, refer to the options given in this post. For instance, when you have multiple instances of Microsoft Edge running and every time you press the Alt + Tab combo nothing happens so you are left with no choice but to minimize everything and then hover your mouse on the icon and switch between the instances of Edge. You will also notice that the right-click on the taskbar won’t respond back and will only keep on showing the loading circle icon. Here are a few tips you can follow to fix the issue with the Windows 10 Taskbar.

Option 1 – Try to restart the Windows Explorer

This is one of the basic things you can try as restarting Windows Explorer helps in refreshing the user interface and makes most of the things work in relation to the user interface.

• To get started, tap the Alt + Ctrl + Del keys to pull up the Windows Task Manager.
• After opening Task Manager, look for “explorer.exe” under the list of programs.
• Once you find the explorer.exe, right-click on it and click Restart.

Option 2 – Try changing the Foreground Lock Time

Aside from restarting Windows Explorer, you could also try changing the Foreground Lock Time to fix the issue with the Taskbar.

• Tap the Win + R keys to open the Run dialog box.
• Then type in regedit in the field and tap Enter to open the Registry Editor.
• Next, go to this registry key – HKEY_CURRENT_USERControl PanelDesktop
• Next, change the ForegroundLockTimeout value from200000 to 0. After that, it will make sure that no other application will take away the focus from your current program or application. It could be that some other application has taken away the focus and even when you try to actually switch, the focus gets back to the old one. Anyhow, since you already changed the value of ForegroundLockTimeout, it will ensure that the focus is not switched.

Note: If you are running some Full-Screen applications there are some devices especially the gaming ones, disable the Windows key to make sure that you won’t be able to switch. If this is the case, you need to make some modifications to the Full-Screen games.

One of the most common and bothersome issues with a printer is when it refuses to get configured or set up on your computer. Thus when your printer has some configuration issues, you will most likely encounter the error 0x00000709. This occurs if there is already a default printer set and configured or Windows does not want to configure the new printer at all. The operation could not be completed (error 0x00000709), Double check the printer name and make sure that the printer is connected to the network. Today, we will try two fixes that may help you get rid of this error.

Option 1 – Run the Printer Troubleshooter

One of the first basic troubleshooting you can perform to resolve the printer issue is running the Printer Troubleshooter. This built-in troubleshooter can detect and automatically fix the problem for you. To use it, follow these steps:

• Tap the Win + R keys to open the Run dialog box.
• Next, type “exe /id PrinterDiagnostic” in the field and click OK or hit Enter to open the Printer Troubleshooter.
• Then click the Next button and follow the next on-screen instructions to fix the issue with the printer.

Option 2 – Try to use some Registry tweaks to add the Printer

You might want to use some tweaks to add the Printer but before you proceed, make sure to create a System Restore Point so that if anything goes out of hand, you can always undo the changes you’ve made.

• Tap the Win + R keys to open the Run dialog box.
• Next, type “Regedit” in the field and hit Enter to open the Registry Editor.
• When a UAC or User Account Control prompt appears, click Yes.
• Once you’ve opened the Registry Editor, go to the following key location:

HKEY_CURRENT_USERSoftwareMicrosoftWindows NTCurrentVersionWindows

• From there, double click on the file named “Device on the right side pane under the Windows folder.
• Now add the name of your printer in the Value Data field as you can see below and then click the OK button.

Note: As you can see on the image above, you must not change the “.winspool.Ne02:” part and only the first one which is the name of your printer.

• After that, you will get a message that says, “Cannot edit Device: Error writing the value’s new contents, simply click on OK again. You have to take note of the existing permissions before you proceed to the next step. Once you’ve added the Printer, make sure to reverse the changes you’ve made to the Permissions.
• Now right click on the Windows folder located on the left pane and click on Permission.
• Select Restricted under the Group or user names section.
• Then check the checkboxes for “Full Control”, “Read” and “Special Permissions” under the Permissions for RESTRICTED section.
• After that click the Apply button and then OK to save the changes made.
• Next, right-click on the file named “UserSelectdDefault” and select Rename to rename it to your printer’s name.
• Now restart your computer to successfully apply the changes made.
• After the printer is added, don’t forget to reverse the Permission changes you’ve made early on.

Option 3 – Try updating the Printer drivers

You might also want to try updating your printer drivers. All you have to do is locate the USB Composite Device. For complete details, follow the steps below.

• 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 USB Composite Device option and right-click on it, and select the Update Driver from the options.
• Restart your PC and then click the “Search automatically for updated driver software” option.

Note: You also have the option to download the latest version of your Printer from the manufacturer’s website.

TPM or Trusted Platform Module version 2.0 is a must-have if you plan on upgrading your system to Windows 11. So what exactly is TPM and do you have it?

What exactly is TPM?

TPM is a tamper-resistant hardware technology tasked with generating and storing encryption keys inside it for better PC security. It can be remotely used to authenticate hardware and software by utilizing a unique endorsement key placed into the hardware itself. This technology can be used for example in BitLocker inside Windows in order to have data on a hard drive encrypted so if the mentioned drive is connected to another computer it would not be able to be accessed since the encryption key is stored in the TPM module. Microsoft is pushing its agenda that Windows 11 must be and must feel like safety first OS which will protect user data and user information and requiring TPM means that each Windows 11 will be secure so no additional software patches will be required for an extra layer of security. Windows 11 will assume that each user has TPM encryption enabled and will be built upon that.

Do you have TPM on your computer?

If your computer or hardware has been purchased in 2016 or later there are very high chances that you already have the required technology to run Windows 11. Unfortunately, many gaming motherboards have not been placing TPM in their boards and you might not have it. Also, there is the option of you having it but it is turned off in motherboard settings making Windows unable to detect it. As you can clearly see there are a lot of scenarios around required tech and honestly it is a complete mess. But lucky for you there are ways to find out do you possess the needed module in order to make an upgrade. On your current computer on which you would like to make an upgrade in your current Windows OS press ⊞ WINDOWS + R to open the run dialog. Inside run dialog type in TPM.msc and press ENTER to open Trusted Platform Module Management on Local Computer. You will immediately receive information do you have the required module. If everything is fine, you are good to go, however, if it says that compatible TPM cannot be found there is a chance that either you do not have needed hardware or it might be turned off inside motherboard settings.

Check motherboard UEFI

If you have a newer motherboard but Windows utility cannot detect TPM there is a chance that it might be turned off directly on your board. In order to check this, you will have to boot up your PC into UEFI either by pressing the corresponding key when it is turned ON or from Windows reboot options. Once you are inside UEFI you need to find security options and see if there is an option to turn ON or enable TPM. Since every motherboard is different and has different UEFI software we cannot cover all of the permutations and the best we can do is hope that provided information is enough. You can also visit your motherboard manufacturer to see instructions for your specific case.

Conclusion

TPM itself is generally an OK idea and I can surely see good sides of it but there is this lurking feeling that generally, Microsoft is not really concerned about the security of our data and that the real requirement for this is trying to battle software piracy. I simply cannot trust company which introduced tons of telemetry tracking through ages and which has done everything in their power to battle non-legal use of their software. I do not promote piracy but I support free choice and besides, who can tell me what will happen if TPM malfunctions, will I lose all of my data forever? It is not so uncommon that TPM has malfunctioned in the past and it is only logical to presume it can do it again in the future but this time we will not have the choice not to use it, we will be forced into it.

Hello and welcome to errortools articles. Today we will talk about some great and awesome tips and tricks for the command prompt. Commands which can make your life easier and your workday more pleasant. That being said let's dive in right into muddy waters and swim out with new knowledge.

Tip 1: Read Motherboard information

There are a lot of reasons why you would like to read information from your motherboard, maybe you would like to upgrade your BIOS, perhaps you would like to know the serial number, maybe even the version number. Well, you can, type the following code into the command prompt and you will receive all information about your motherboard.

wmic baseboard get product,version,serialnumber,product

Tip 2: Copy command output to clipboard

Getting information from the command prompt to a word processor, into an email or any other medium can be somewhat troublesome, usually, people tend to screenshot or write from a command prompt into another destination, which could induce errors, and let's be honest, it is not practical. You can copy command output directly into the clipboard ready for pasting it anywhere with | clip. So for example if you would like to paste the directory structure of your c drive command would look like: dir c: | clip, now output would be placed into the clipboard ready to be pasted anywhere needed.

Tip 3: Erase data permanently

When you delete data on your hard drive, what really happens is that files are marked with a marker which marks that space for new data writing, but the data itself is still present and can be brought back. This sometimes could impose problems but if you would type: cipher /w:c Windows will write random data over each marked file deleting it forever without means to be brought back.

Tip 4: Manage your IP address

If you would like to play with your IP address and do fancy stuff with it do the following: ipconfig /release to release your IP address ipconfig /renew to renew your IP address ipconfig /flushdns to flush down DNS information and enjoy a new browsing start.

Tip 5: Check to see are packets reaching the desired location

You installed a new LAN printer, or a new switch, maybe you want to check if your new site is up and running. Use ping destination in order to see if TCP packets are reaching desired information, you can use it with a specific address like ping 192.168.1.1 or you can type a web address, for example, ping google.com and see if a connection can be established.

Tip 6: Get information about a specific command

So you learned some command prompt commands, but you do not know all of their configuration or switches? No worries, just type command/? to get a list of available switches for it. For example ipconfig/? will write you a list of available switches for ipconfig command.

Tip 7: Link and execute multiple commands one after another.

Let us say that for example, you would like to copy files into a different folder, then rename some and delete others and you need to do a couple of times. Instead of writing command after command once each one is finished link them with && and they will execute one after another.

Tip 8: Scan and repair files.

In order to scan files and repair broke or corrupted ones write in the command prompt: sfc /scannow. Please know that this command can take a long time since it is solely dependant on the number of files, their size, and the power of the computer.

Tip 9: Manage and configure your computer energy

Command powercfg will let you manage and see the power configuration of your computer. Just write powercfg/? and see what you need and want to change or get information about.

Tip 10: Associate files with applications

Windows already has some file associations defined, and some applications take over some type of files but if you want to take control into your own hand use assoc command. For example assoc.txt= "APPLICATION NAME" will associate txt files with the provided application.

Tip 11: Hide files and folder.

Do you have some folder or file with information that you do not want to be seen when someone opens file explorer? Use attrib +h <name of file> and hide file or attrib +h /D <folder name> to hide folder.

Tip 12: Get a list of installed computer drivers

Want to know which drivers are installed in your system? Use driverquery and take a look.

Tip 13: Find and locate shared folders

have you shared a folder but forgot which one and where? Do not bang your head on the wall, we have a simple solution for you. just type in command prompt net share and see everything.

Tip 14: Run commands as an administrator

You do not have administrator privileges? Do you want to bypass common blockades?

runas /user:yourdomainadministrator command

That is all that we have for you today, I certainly hope you have found something useful here and that we have managed to teach you some valuable things.

If you suddenly encounter an error saying, “Something happened and this app couldn't be installed. Error Code: 0x80244018”, when trying to install apps on your Windows 10 computer, then you’ve come to the right place as this post will help you in resolving the problem. It’s not just you that’s experiencing this problem right now as several users also reported getting this error they try to apply a Windows update or download and install the application from Microsoft Store. There could are several reasons why you’re getting this error. It could be caused by a third-party application, or it could be that the update is blocked by your VPN or proxy server, or that the BITS service is disabled. In addition, the error could also be due to some glitch in the component services or it could be that the system files are corrupted. Whatever the cause is, you can fix the error by following any of the given options below.

Option 1 – Run the Windows Update Troubleshooter

Running the Windows Update Troubleshooter can help in fixing Error Code 0x80244018. To run it, go to Settings and then select Troubleshoot from the options. From there, click on Windows Update and then click the “Run the troubleshooter” button. After that, follow the next on-screen instructions and you should be good to go.

Option 2 – Put your PC in a Clean Boot State

It could be that some third-party application is the one that’s causing the problem so it’s best if you put your computer in a Clean Boot state. During this state, you can start the system with a minimum number of drivers and startup programs that will surely help you in isolating the root cause of the issue.

• 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.)
• After that, try to install the Windows app again.

Note: If you are able to install the app without any trouble at all then it means that the error is caused by some third-party application on your computer. You need to look for the culprit and uninstall it once you found it.

Option 3 – Restart BITS

The Background Intelligent Transfer Service or BITS is a part of the Windows Update service and is the one that manages the background download of Windows Update, as well as scans for new updates and so on. And if Windows Update is experiencing some problems, you can try restarting BITS but make sure that you have admin privileges to do so.

• Tap the Win + R keys to open the Run dialog box.
• Next, type “services.msc” in the field and hit Enter to open Windows Services.
• From the list of Services, look for the Background Intelligent Transfer Service and double-click on it to open Properties.
• After that, you need to set the Startup type to “Automatic (Delayed Start) and click on Apply.
• Now click the Stop button to stop BITS and then click the Start button to restart the service.
• Click OK to save the changes made and then restart your PC.

Option 4 – Disable the Proxy server

• Tap the Win + R keys to open the Run dialog box.
• Then type “inetcpl.cpl” in the field and hit Enter to pull up the Internet Properties.
• After that, go to the Connections tab and select the LAN settings.
• From there. Uncheck the “Use a Proxy Server” option for your LAN and then make sure that the “Automatically detect settings” option is checked.
• Now click the OK and the Apply buttons.
• Restart your PC.

Note: If you are using a third-party proxy service, you have to disable it.

Option 5 – Try disabling the VPN

As mentioned, if you are using VPN, this could be the reason why you’re getting Error Code 0x80244018 so the most obvious thing to do is for you to turn off the VPN and try to run the Windows Update once more. And if you use a VPN software that works using their software, you can just completely exit or log-off from its account. On the other hand, if you are using a built-in Windows 10 VPN, you can simply turn it off or delete all the settings you have created there. Although it’s understandable that you might have to use a VPN connection to connect to the work network, you really have to disable it at least after you’ve successfully installed the app.

Option 6 – Reset Windows Update components

• Open Command Prompt with admin privileges.
• After that, type each one of the following commands and hit Enter after you key in one after the other.
  • net stop wuauserv
  • net stop cryptsvc
  • net stop bits
  • net stop msiserver

Note: The commands you entered will stop the Windows Update components such as Windows Update service, Cryptographic services, BITS, and MSI Installer.

• After disabling WU components, you need to rename both the SoftwareDistribution and Catroot2 folders. To do that, type each one of the following commands below, and don’t forget to hit Enter after you type one command after the other.
  • ren C:WindowsSoftwareDistribution SoftwareDistribution.old
  • ren C:WindowsSystem32catroot2 Catroot2.old
• Next, restart the services you’ve stopped by entering another series of commands. Don’t forget to hit Enter after you key in one command after the other.
  • net start wuauserv
  • net start cryptsvc
  • net start bits
  • net start msiserver
• Close Command Prompt and reboot your PC.

Option 7 – Run the System File Checker Scan

System File Checker or 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 that might be the cause why you’re getting the Error Code 0x80244018. 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.

• Restart your PC.

Option 8 – Run the DISM tool

You can also run the DISM Tool as it helps in repairing the Windows System Image as well as the Windows Component Store in Windows 10. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth” which could help in fixing the Error Code 0x80244018.

• Open the Command Prompt with admin privileges.
• Then type in the following commands and make sure to hit Enter right after you type each one of them:
  • Dism /Online /Cleanup-Image /CheckHealth
  • Dism /Online /Cleanup-Image /ScanHealth
  • exe /Online /Cleanup-image /Restorehealth
• Do not close the window if the process takes a while as it will probably take a few minutes to finish.

Things have stirred lately with Chinas ban on crypto mining and many used GPUs will flow the market probably. But should you buy a used GPU? Short answer: NO, long answer: keep on reading to find out why.

GPU shortage and its cause

As you all know by now, we live sadly in a world struck by a global Pandemic. Due to this awful disease and measures taken against it, many people are either working from home or are at home making the manufacturing of new chips problematic while demand on the market has raised. Throw into that mix crypto mining which has raised in popularity and you have, well today's market where we have GPU shortage. Now with the latest news that China has banned the mining of cryptocurrency, there is to be expected that at some point in time mining cards used there will fit the market in the whole world. Sadly even with a large quantity of GPUs that will become available, the overall price of cards will not be much lowered I am afraid since demand is still very high and many people would not want to purchase used mining cards and neither should you.

Be prepared for the worst scenario

Although this sounds very pessimistic and in most cases, it will not turn out to be true, you should always prepare yourself mentally that you might be in that lower percentage that will end up with a really bad GPU. What has come up to be absolutely true when considering GPU that were mining is that if anything at all can be done to GPU in order to increase performance, it has been done. Miners want to optimize and almost every GPU if could be overclocked, it was overclocked. Extensive mining also means that thermal paste has been dried and it is pretty useless at this point and there is a very high chance that fans and heat sinks will need much cleaning or even replacement raising the price of the card itself for mentioned paste, fans, and heat sinks. There's no way to tell what the previous owner might have done with a graphics card when you're shopping online, so our advice is to assume the worst. Don't trust the seller to give truthful information. Any listing that says it was "never used for mining" at this point is probably a lie.

Age of the GPU matters

Date when GPU itself has manufactured really matters. Newer cards even if used extensively have been used for a much shorter period of time and are not so damaged were ones produced a few years ago have seen a lot of action. Let’s say that you get RTX 3060, In the worst-case scenario it has been mining since late February of 2021 and basically, it is still under warranty so it should behave OK and put some good work in gaming even in that state. On another hand, if we take for example GTX 1080Ti which is 4 years old GPU things start to change drastically. 4 years GPU could be worn out even if it was used just for extensive gaming sessions let alone for mining.

No return policy and seller rating

Most of the time you will run into a product that cannot be returned or no refunds policy. This should bring a red flag right away and deter you from purchase. Sellers with the highest ratings are more trustworthy since many of them will not want to destroy their reputation but these will probably not even have these kinds of merchandise in their store. Buying with a poor rating seller and no return policy on a product is just asking for trouble. And although some stores do have arbitration and will stand on the customer side there is no guarantee for that and it will take too much time to process.

If you really must buy a second-hand GPU

Of course in these troubled times sometimes due to malfunction or any other reason, there would not be another choice than to buy a second-hand GPU. In this case, if there is no other option consider sellers with many positive ratings. If you can buy locally that would even be better or the best-case scenario would be if you could visually see and inspect GPU itself in order to see in what state it is. Look for warranty stickers to see if they are thorn and the card has been tampered with. Also take a good look at screws, if they have scratches card has been opened, probably to replace fan or heating sinks which means that it has worked a lot.

Conclusion

It is very difficult to give the best possible advice on this situation since of GPU shortage, but I would much prefer a new GPU with lower performance than a hi-performance one which was mining.
