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.

Hacker group recently came up with claims that they have stolen data from 100 million T-Mobile customers. T-Mobile has responded with confirmation it has been compromised and that over 40 million records were stolen, among them are not just present customers, but anyone who has applied for T-Mobile service as well as past accounts.

What has been stolen?

Report from T-Mobile states that stolen records included first and last name, date of birth, social security number, driver’s license & ID information. The company said that it has “no indication that the data contained in the stolen files included any customer financial information, credit card information, debit or other payment information.” Not really a reassuring statement meaning that they really do not know, but even if the statement is true, already stolen information is as much if even not more damaging and devastating as payment information.

What T-Mobile is planning to do now?

It is stated that the hole used for the hack has been addressed and closed so no more data can be stolen. Considering people that had their personal information compromised, T-Mobile said it is planning to reach out to them and offer them two years of free identity protection through McAfee’s ID Theft Protection Service. Additionally, T-Mobile recommends postpaid customers change their PIN by going online into their T-Mobile account or calling T-Mobile customer service by dialing 611 on their phone. The company also recommends a feature called Account Takeover Protection that prevents unauthorized individuals from stealing a phone number and porting it out of T-Mobile. Finally, the company will publish a website “for one-stop information and solutions to help customers take steps to further protect themselves.”

What is the Error Code 0x6d9?

If you have a firewall installed on your system, you may come across the error code 0x6d9.  This error occurs when opening Windows Firewall with advanced security. The error code 0x9d9 is displayed as:

“There was an error opening the Windows Firewall with Advanced Security snap-in. The Windows Firewall with Advanced Security snap-in failed to load. Restart the Windows Firewall service on the computer you are managing. Error code: 0x6D9”

This occurs when the Windows Firewall service is missing. The service doesn’t start due to permission errors on various registry keys. It is a critical blue screen of death error code that turns the computer screen blue and causes the Windows to shut down. If this error code is not fixed it may start appearing more and more frequently resulting in total system corruption.

Solution

Error Causes

Virtually, the underlying cause for Windows Firewall error code 0x6d9 is a damaged registry. The registry is the database of the system that saves all the activities including web browsing and programs installed and uninstalled and junk files on the PC. The registry saves all the information in the RAM, your hard disk. As the disk gets filled with files, it then requires more power to run which impacts the performance of the PC and slows it down. Simultaneously, since the hard disk is overloaded with data, it exposes the registry to file damages, fragmentation, and corruption which then eventually causes hindrance in running calling programs and running them on your system because files are either corrupt or missing. Other than cluttered disk issues, registry errors also occur due to viral and malware attacks. If the Firewall is inaccessible, your system is prone to malware.

As of the time of writing this article you no longer need or are required to have a password if you plan to log in to your Microsoft account. Microsoft explored various options for account security and came to the conclusion that passwords are obsolete. Microsoft is letting you access your account through the Microsoft Authenticator app, Windows Hello, a security key, SMS verification, or email verification code. All of these methods are way better in terms of security than passwords.

How to turn these features on?

To get rid of your Microsoft password, the process is simple. You simply need to go to your Microsoft account, click “advanced security options,” then “enable passwordless accounts” under the Additional security section.

Hello everyone and welcome to our Windows 10 security basics where we will provide you with common practices you should aim to follow in order not to cough some viruses, malware, keylogger, worm, etc. As you are all aware, we live in a digital age where we are surrounded by luxuries of unlimited information, video chats all over the globe, free calls via the internet, applications that track stuff for us, and many many more things that make our lives easier. Sadly with this kind of technology comes risks of cyber attacks that aim to steal your information, credit card numbers, or any other relevant stuff which could be used illegally in order to make purchases, loans, and other theft in your name so ones doing that could not get caught. Think of data stealers the same as you think of armed robbers in a dark alley, just this time their pray is data about your life so they can make purchases for themselves more than once. This article aims to provide you with some common logic, tips, and tricks of what should you do and where should you pay attention in order not to provide wrong people with your crucial information and data. we hope that you will find reading informative and helpful.

1. Keep Windows updated.

   Microsoft is working hard on their Windows defender and firewall to provide protection to its users and fixing any introduced security leaks which are found in Windows itself. By updating and keeping Windows updated you make sure that every security leak that is found is patched and removed from Windows and that you have the latest database of known malware inside the firewall and defender. This common practice, however, should not be limited to Windows only, you should update every application you are using for the same reasons.

2. Use antivirus, anti-malware, and firewall

   These applications exist for a reason and that reason is to protect your data. Dedicated applications specifically made for purposes of defending your data are better than any kind of I am careful mentality since sometimes is enough to just visit a website or just click on some link and you are compromised. You can use Windows Defender and firewall if you wish, they are already in Windows but if you are serious about your data and like to surf the internet some better protection is worth the investment.

3. Get a dedicated password manager

   Your password is bad, if you use the same password everywhere then it is even worse. Computers have come a long way in the last 50 years and so have cyber attack applications which make your commonsense passwords extremely vulnerable and all of your accounts open to cyber attacks. Dedicated password managers that can hash passwords and automate them are your safest bet that your passwords will not be compromised, get one, and get it today.

4. Do not click on anything inside emails

   Cyber attacks come in vast variety and one of them is sending you emails informing you that for example your Paypal or anything else has been hacked and that you must click this link to reset your password. These you do not click, no matter how convincing they sound or how good they look, if you need to update your information on a specific service or website, you delete email, open browser and go to that service and change stuff. The same goes with different offers, discounts, women seeking you, men seeking you, prince sending you 1 billion in gold. Only click on links in emails from a trusted and verified source.

5. Do not click on pop-ups

   Similar to clicking on links in emails you should not click on pop-ups, the same rules, same stuff apply as with emails.

6. Be careful what you are downloading

   Be careful from where you download your software and be careful what are you downloading and stop using pirated software, any kind of malicious applications, keyloggers, viruses, etc could be hidden in these downloads, and by downloading them you are opening doors to your private information. Only use legal software from trusted sources.

7. Never leave your phone or computer unattended

   You can never tell who can implement malicious software or get some crucial information from unattended devices, lock them all time and take them with you.

There you go, 7 common tips and tricks for the basic security of your computer. Thank you for reading and I hope to see you again on our site.

Microsoft has presented its next version of their flagship product, Windows 11, and feelings are divided among users. Some users like it very much and eager to upgrade, some do not like the graphic overhaul it went through, but overall I think Microsoft has done a good job with it. Here in this article, we will discuss some of the new features which Windows brings to the table, well at least ones that were showed, I am sure there are plenty more which we will see once OS has been released.

New Start menu

One of the first things that everyone saw when Microsoft has unveiled Windows 11 is its Start menu. Funny enough this is what has caused most of the divide among users, some find it interesting, and some do not like it. Truth is, it is different, and it is centered in the middle instead of the lower left part of the screen. It has been confirmed however that the Start menu can be moved to any part of the screen so if you want, you could place it on the lower left as it has always been. Live tiles do not longer exist in the Start menu, instead, we have styled simple icons.

Windows 11 Snap controls are great

If you have used the cascade option in previous Windows versions then it is most likely that you will like the new Snap controls. You can quickly snap windows side by side, or arrange them in sections on your desktop just by hovering over maximize button on the title bar.

Windows 11 File Explorer

File explorer has gone through some visual and design changes, the ribbon on top has been completely removed and replaced with a header-like feature with a slick and clean design. The header contains a nice organized and designed single row of icons like cut, paste, copy, rename, delete, and new folder icons.

Settings app ovberhaul

The settings app also has gone through visual and design changes. It has a new design that is very visually appealing and navigation has been simplified and more organized. Finding the right and desired setting is much faster and clearer now.

Widget tab makes comeback in Windows 11

Yes, widgets are back but not like you remember them. Instead of being all-time present at your desktop like once they used to be, now there is a button on the taskbar which brings the widget bar up that contains desired widgets. This way they are easily accessible and do not clutter desktops. So far we have weather, news, calendar, and stocks widget but we will see how development on these goes. I expect to have community-made widgets like in old days for all of our needs.

XBOX app

The new Xbox app is now integrated into Windows 11, offering quick access to Xbox Game Pass games, the social parts of the Xbox network, and the Xbox store.

Security and TPM 2.0 in Windows 11

As widely known by now Windows 11 will require you to have a TPM 2.0 module capable CPU in order to install it. This system requirement has caused a lot of controversies but essentially it seems that MS's goal is to protect your personal data by using this module. The upside of course is that your data will be protected much more than in previous Windows versions, the downside, of course, will be that you will need newer hardware to run OS on it. and that is essentially it, keep on tuned on more Windows 11 information and overall articles tied to PC and technology here at errortools.com

Support for Bluetooth hardware has always been included in the Windows 10 operating system for a long time now. And it just keeps getting better especially now with the support for the latest version of Bluetooth 5.0 LE. However, there are still times when Bluetooth experiences a couple of issues one of which is users were not able to turn on or off Bluetooth on their Windows 10 Pc since the option to turn Bluetooth off or on is missing in the Windows 10 settings app and even in the Action Center. So if you are one of the users who experience the same problem, read on as this post will guide you in resolving the issue. To resolve this Bluetooth issue, here are some suggestions that could help:

Option 1 – Try running the Bluetooth Troubleshooter

As you know, Windows 10 has various troubleshooters with user-friendly interfaces where you can utilize them to fix issues in your PC. And since you’re dealing with some Bluetooth problem, you have to run the Bluetooth Troubleshooter.

• Open the Windows 10 Settings.
• Then go to Update & Security > Troubleshoot.
• You should find the option for Bluetooth on your right-hand side – click on it then click on the “Run the troubleshooter” option.
• Now follow the next screen options.

Option 2 – Try to reinstall or update the Bluetooth driver

The issue might have something to do with the Bluetooth drivers. It could be that it is outdated and needs to be updated or that you recently updated it and since then you have trouble removing the Bluetooth devices and so to fix the issue, you can update, roll back or uninstall the Bluetooth drivers. How? Follow the steps below.

• Tap the Win + X keys to open the Device Manager.
• Next, look for the Bluetooth device and right-click on it.
• Select the option “Update driver”.
• After that, a new popup window will appear. In there, select the option, “Search automatically for updated driver software”.

Note: Checking the update may take a few minutes so you’ll have to wait until it finishes. If it is able to find an update, you must install it. And if you want to reinstall the Bluetooth driver, just select the “Uninstall driver” option and follow the next on-screen instructions that follow.

Option 3 – Configure the Bluetooth Services

If the first two options didn’t work, the next thing you can do is configure Bluetooth Services. How? Simply follow these steps:

• Tap the Win + R key combination to open the Run dialog box.
• After that, type “services.msc” in the field and hit Enter to open the Windows Services Manager.
• You will then see a list of services and from there, look for the following services and make sure that their default values are set as follows:
  • Bluetooth Handsfree Service – Manual (Triggered)
  • Bluetooth Audio Gateway Service – Manual (Triggered)
  • Bluetooth Support Service – Manual (Triggered)
  • Bluetooth User Support Service – Manual (Triggered)
• Now click on the Start button to start all the aforementioned services and then check if you can now see the option to turn Bluetooth on or on.

As in previous Windows 10, inside Windows 11 also when you press the ALT + TAB key combination you will get a preview of all running applications along with all Browser tabs so you can go through them and pick the one you want to switch to. Alto, I personally am a big fan of alt-tabbing, I must admit that I am not a big fan of having multiple browsers tabs on screen when I do press key combo. Luckily there is a very easy way to turn this feature off. Turning browsers tabs thumbnails off

1. Press ⊞ WINDOWS + I to open settings
2. Click on System in the sidebar
3. Scroll down and select Multitasking
4. Find Alt + Tab section and click on the drop-down menu
5. Pick Open Windows Only
6. Close settings

Now when you press the ALT + TAB key combination you will still see your browser but only an active tab in it instead of all tabs as different preview thumbnails.

In case you don’t know, Microsoft hooks up every machine that is running Windows 10 with an Advertising ID which helps them in providing Windows 10 users with relevant ads. These ads are delivered to users in the Action Center, Start Menu as well as the ads inside the UWP Applications. What makes these advertisements relevant is that they keep track of your browsing trends, likes and dislikes, with the help of the Advertising ID. However, if you are not fond of advertisements and you do not want this feature of Microsoft to track your usage, worry not for you actually have the option to disable targeted ads on your Windows 10 computer by turning off the Advertising ID. And you can do that during Windows 10 Setup or using the Group Policy Editor. For more details, refer to the instructions provided below for each one of the methods.

Option 1 – Turn off Advertising ID during Windows 10 setup

If you are about to install Windows 10, then during the installation process, your computer boots into the Install and Configure Windows 10 screen with Cortana that assist you during the setup. Once you reach the last page which is “Choose privacy settings for your device”, you will see the Advertising ID of your computer. Under the Advertising ID, you have to disable or toggle off the “Apps can use advertising ID to provide more personalized advertising in accordance with the privacy policy of the app provider” option. After you disable it, click on the Accept button to proceed with the installation. After that, the copy of your Windows 10 you are using will have the Advertising ID disabled by default.

Option 2 – Turn off Advertising ID via Group Policy Editor

• First, tap the Win + R keys to launch the Run utility.
• Then, type “gpedit.msc” in the field and click OK or tap Enter to open the Group Policy Editor.
• Next, navigate to this group policy setting: Computer Configuration > Administrative Templates > System > User Profiles
• Now double click on the “Turn off the advertising ID” option and set the radio button to Enabled. Once you do, you will see the following description on your screen:

“This policy setting turns off the advertising ID, preventing apps from using the ID for experiences across apps. If you enable this policy setting, the advertising ID is turned off. Apps can’t use the ID for experiences across apps. If you disable or do not configure this policy setting, users can control whether apps can use the advertising ID for experiences across apps.” Note that setting the radio button to Enabled or Not Configured will turn off the data collection of the Advertising ID.

• Finally, exit the Group Policy Editor and then restart your computer to apply the changes made successfully.
