Direct replacement for Apple M1 Chip is near. There were some M1 Chips versions like M1 MAX and M1 ULTRA that were upgrades of the existing M1 chip, but the new and upcoming M2 is something different and it is aiming to replace M1 completely.

Made in a 5-nanometer design, with 20 billion transistors and 100GB/s of unified memory bandwidth is meant to increase performance over M1. It has the same M1 8 core design with 4 high-efficiency cores and 4 high-performance ones.

All CPU and GPU cores are faster than their M1 equivalents and Apple states that when running M1 and M2 at the same power level M2 will perform 25% faster. The first version of the chip will place focus on power efficiency so if you are more on side of being a power user wait for the MAX or ULTRA version of M2.

Tech details of M2

M2 system on a chip like its predecessor M1 combines both CPU and GPU on a single chip with shared memory in order to increase performance compared to systems that have separate CPU and GPU. M2 so far has been only announced for MacBook Air and the 13-inch MacBook Pro that suppose to hit the market somewhere around July this year. Of course, we expect that M2 is included in future iPad series or Mac Mini series as well.

• CPU Cores: 8
• GPU Cores: Up to 10
• Unified Memory: Up to 24 GB
• Neural Engine Cores: 16
• Number of Transistors: 20 billion
• Process: Second Generation 5nm

If you are familiar with the Dynamic Lock feature in Windows 10, then it has probably made it easier for you to lock your computer the instant you move away from it. This interesting feature does not need any special software like IR Cameras to use this feature as long as your Windows 10 computer supports Bluetooth which it most likely does. However there are times when the Dynamic lock feature is either missing or not working. When that happens, here are some suggestions that could help you. But before anything else, you need to create a System Restore point first since you will be modifying some critical system settings as well as registry files. After you’ve created a System Restore point, refer to the following options below to fix the issue with Dynamic Lock.

Option 1 – Try using the Settings app

• Tap the Win + I keys to open the Settings app and then navigate to Accounts > Sing-in options.
• After that, scroll down until you see the Dynamic Lock section.
• Next, make sure that the checkbox for “Allow Windows to automatically lock your device when you are away” is checked.
• Now that you’re all set, exit the Settings app.

Note: If for some reason the above-given solution didn’t work, you can try the next options below.

Option 2 – Try to pair your Bluetooth Device

If you get a message saying, “Allow Windows to automatically lock your device when you are away” in the Notifications Center or in the Settings app, then you need to pair your Bluetooth device. To do so, follow the steps below.

• Go to Settings > Devices > Bluetooth & other devices.
• From there, make sure that Bluetooth is turned On and then pair your Bluetooth device.
• And if you open the Windows Defender Security Center, you will see the following message as well.
• Simply click on the Add Bluetooth device button and it will open the Bluetooth settings where you can also pair the device.

Option 3 – 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 device 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 4 – Try to use the Registry Editor

• Tap the Win + R keys to open the Run dialog box and then type “Regedit” in the field and hit Enter to open the Registry Editor.
• If a User Account Control or UAC prompt appears, just click on Yes to proceed.
• After that, navigate to the following registry key:

HKEY_CURRENT_USERSoftwareMicrosoftWindows NTCurrentVersionWinlogon

• Next, look for a DWORD named “EnableGoodbye” located on the right-side panel and then make sure that its value is set to 1 which means that it is enabled while 0 indicates disabled.
• Now close the Registry Editor and restart your computer to apply the changes made successfully.

Option 5 – Try checking the Group Policy setting

If your Windows 10 version has the Group Policy Editor, you can use it to fix the Dynamic Lock issue as well. Simply follow the steps below to use it.

• Tap the Win + R keys to open the Run dialog box.
• Then type “gpedit.msc” in the field and hit Enter to open the Group Policy Editor.
• Next, navigate to the following path:

Computer ConfigurationAdministrative TemplatesWindows ComponentsWindows Hello for Business

• After that, look for an entry named “Configure dynamic lock factors” and double click on it to open a new window.
• Once you enable this Group Policy setting, the signal rules will be evaluated to detect the absence of a user and will lock the device automatically. On the other hand, if you disable or don’t configure this setting, you can continue locking your computer with existing locking options. Take note that it may be Not configured or Enabled but shouldn’t be set to Disabled.
• Now select the radio button for Enabled and set the Signal rules then click OK.
• Then exit the Group Policy Editor and restart your computer.

Resource hogging is a term when one single application or few of them are taking all system resources for themself causing extreme slow down in the computer and nonresponsiveness. It can be a very frustrating and time-consuming experience and it can cost you money if you can not finish work on time due to this effect. I believe that everyone has experienced at least one slowdown in their IT carrier because of resource-hogging applications and most users do not know how to deal with this. We are here to help you with this issue. Just to be aware that this method shown here is not a method to miraculously speed up your PC or anything similar, this is to be able to detect and recover from extreme slowdowns. Hardware components are still very important and if you can upgrade your computer if it is outdated, please do it because new applications will require a more modern system, and not any kind of tips and tricks will save you from outdated hardware.

Identifying resource hogging app

Now when we got that out of the way let's talk about slowdowns, it is no secret that sometimes an application has bugs and memory leaks that can cause this kind of behavior, and sometimes the application simply takes up too much memory for any other application to work normally. The most simple and straightforward way is to bring up a Windows task manager and inspect running applications and services. You can bring task manager by the key combination of CTRL + SHIFT + ESC If the system is in deep memory deficit you will have to wait for the task manager to open and show itself on-screen. Once opened, click on more details if that view is not opened by default. Once the view expands you will see all running applications with how much RAM memory have they taken and how much CPU they are using.

What to do with app?

Now you are presented with a choice on what to do with the problematic application. If you press the end task button on the bottom right, Windows will kill the application and its processes but any unsaved work inside the application will be lost and unrecoverable in most cases. Or you can try to remove smaller applications running to free up more memory and CPU in order for the computer to catch up. Any choice you make is up to you, but be very careful not to kill Windows essential service by mistake, that will cause immediate system instability with high chances of a system crash.

Error Code 0x80073afc - What is it?

Error code 0x80073afc deals with an antivirus program first built into Windows 8/8.1 This error occurs when Windows Defender, the built-in anti-virus software in Windows 8/8.1 and higher, does not start automatically and users attempt to manually start the program.

Solution

Further Information and Manual Repair

Users have found several manual repairs that have fixed the problem without needing to contact technicians for extra help. While the methods below should solve your problem easily, if this is the first time you have encountered the issue you may want to do a simple restart. This has fixed the problem for some users and is the easiest first troubleshooting move. If it doesn’t work move on to the methods listed below, which are easily completed without extra help.

Before trying any of these methods, please make sure that you are logged into a profile that is listed as the administrator of the computer of his administrative powers enabled. If this is not the case you will not be able to complete the following methods. Please log out and log back in on the administrator profile.

Method 1:

First, check to see if you have a third-party anti-virus program installed on your computer. Some users believe that the built-in Windows Defender program is not powerful enough to handle the safety of their computer so they usually download a third-party program. However, that program may have caused a conflict with Windows Defender and may not allow it to open. If you do have a third-party program installed, try uninstalling it then manually starting Windows Defender.

Method 2:

If method one does not work, you may be infected by malware or a virus that has tampered with the settings on your computer and will not allow Windows Defender to start automatically or manually.

First, open Run by holding the “Win” key and pressing the “R” key. Then type “Regedit”. The program will ask for permission to follow through with this action. Click on “Yes” and the Open Registry Editor will open.

Find the HKEY_LOCAL_MACHINESoftwareMicrosoftWindows NTCurrentVersionImage File Execution Option and check to see if there are any files similar to MSASCui.exe or MpCmdRun.exe. If there are any file entries that resemble that, you will want to right-click on them before selecting the “Delete” option. If you do not see any entries that match, this is not the issue with your Windows Defender and you will want to try another method.

The Registry on your computer is very important. It helps tell your computer what programs are safe to run, what programs should be run, and what programs should not be run. If it is tampered with by a virus or Malware, multiple system operations can be affected.

However, if you did find similar file names, and you deleted them, try to start Windows Defender manually. If it does not work again, move on to the next method. 

Method 3:

If the first two methods do not work for your issue, and you are still receiving error code 0x80073afc when attempting to start Windows Defender, this step should solve the problem if you have Restore Point installed on your computer, which you most likely do.

For this method, we will be restoring your computer to a previous Restore Point. First, just like in method two, hold the “Win” key and press the “R” key. This will open run. Next type “Rstrui.exe” and click “ok”. After some time, you will see System Restore Windows. Click “Next” and select the restore point that you would like to go back to. After your computer has restored to the point you selected, check to ensure that Windows Defender has started correctly.

If the above methods aren't able to rectify the issue, you might have to download and install a powerful automated tool to get the job done.

There are a lot of reasons to ban or block different websites in your Windows. From wanting to limit yourself from distraction to block certain sites for sake of kids not going into them. Whatever your reason might be, keep reading in order to find out how you can block any website inside Windows for all browsers. The technique I am going to share with you is universal and not tied to Windows versions, they will work in any Windows from XP onward. Also, the technique will block desired websites on any browser, already installed or even ones that will be installed after doing the trick. And we will also be looking at applications that can help you in this task if you do not wish to do it manually.

Block websites using dedicated software

A small free application called Focal Filter which can be found here: https://www.focalfilter.com/ is a software solution for your needs. It is a pretty straightforward and easy-to-understand application and not really much can be said here about it. You simply download and install it, set your websites, and you are done, the app does rest.

Blocking manually via host file

Another method besides mentioned one using the dedicating application is to manually set site addresses inside the Windows host file. The first thing, of course, is to open the host file, run a notepad with administrator privileges, go to file open, and navigate to c:\windows\system32\drivers\etc\hosts. Once the file is opened go all the way down and add: 127.0.0.1 SITENAME For example: 127.0.0.1 www.youtube.com or 127.0.0.1 www.facebook.com This way each time user on a PC tries to access a listed website computer will reroute it to the given address which is your PC's local address and asked website will not be able to load.

Website breaches and stealing user data is nothing new in the world of the internet. Although a very unpleasant experience it still happens even on some high-quality websites. In this article, we will not focus on how can you not be the target of this kind of attack, because you really cannot. Weel you can kind of if you decide not to have your data on websites at all, but let's just say that is not something you are willing to do.

So, in this case, you have some social, forum, or gaming accounts but you heard that service has been breached and that your email or password might be stolen. Well in this case all you need to do is of course to login into the service and change your password. But, what happens if you are not aware at all that service has been compromised?

Mozilla foundation has asked themselves this same question it seems and they have decided to help us out. They have placed a free online service where you can just by typing in your email address find out if your email or data has been compromised in any way.

Go to https://monitor.firefox.com/ and check it out, if you find out that there is some website that you did not know was breached, change your password right away, and if you have used the same password for anything else (I hope not), change them as well.

Error code 0x8007007b - What is it?

Error code 0x8007007b will present itself when Windows users are trying to activate Windows. You may try to activate it through the update and security option, but it is likely that you will receive the same error code. Error code 0x8007007b may be presented when Windows 7 and Windows 8.1 users try to upgrade and activate Windows 10 on their computer.

Common symptoms include:

• An error message will display that says Windows cannot be activated. The KMS host cannot be located in the DNS, please have the system administrator verify that the KMS is published correctly in DNS.
• Error 0x8007007b will be displayed, stating that the file or directory name or the volume label syntax is not correct.

Solution

Error Causes

There are multiple causes for the user to see this error code, including if a user is using volume-licensed media while installing a number of various Windows operating systems. This error may also be caused because the activation wizard cannot connect to a KMS host computer. It is likely that if the user has a volume-licensed form of media, they were likely given a MAK (multiple activation keys).

Further Information and Manual Repair

There are several ways to go about repairing error code 0x8007007b. It is important to try all of the methods, but if it is too difficult or you do not know what you are doing, please do contact a Windows repair technician. They will likely be able to fix the problem with ease.

Method One: Instead of KMS activation, use a Multiple Key Activation

When KMS activation is not used, and when there is not a KMS server, the product key type should then be changed to a MAK. For MSDN (Microsoft Developer Network) or TechNet, the SKUs that are listed on the media are generally volume-licensed media, and that means that the product key that is supplied is a Multiple Activation Key.

To change the KMS to a MAK, click Start, All Programs, Accessories, and then right-click on Command Prompt. Click Run as Administrator. If prompted for a password or confirmation, enter it now.

When the command prompt opens, type in the following command, and press enter after:

slmgr -ipk xxxxx-xxxxx-xxxxx-xxxxx (these x's are representative of the MAK product key).

Method Two

While on the desktop, press the Windows key and R. The Run window should appear, and then you should enter the following command: Slui 3. Press Enter and then wait for the window to appear. This window will ask for the operating system activation product key. Enter the product key and then press the Activate button. Reboot the computer. Now the Error Code 0x8007007b should be gone.

Method Three

Open the Command Prompt with access as administrator as mentioned previously. Enter the following command: sfc /scannow. The command will then complete its task. This will take a good bit of time, so leave the computer to do its work. The sfc must finish the scan. When the scan has finished, reboot the computer. Now you can check for activation. The error code should be gone.

Method Four: When the client can't locate a KMS host on the network to complete activation

This method for correction should be used when the network does have a KMS host computer setup, and the client is not able to locate the KMS host on the network to complete activation.

To verify that the computer does in fact have the KMS host installed. Click Start, All Programs, Accessories, and then right-click on Command Prompt. Run as administrator. If you are now prompted to enter a password or confirmation, do so. When the command prompt box comes up, type in the following command, and then press Enter: nxlookup -type=all_vlmcs._tcp>kms.txt

The command will generate a file, open this KMS file. The file will contain one or more entries. As a default, the KMS host server will dynamically register a DNS SRV server evidence once every 24 hours. In order to check the registry to ensure that this is happening, follow these steps:

• Click Start, type in regedit, and then press Enter.
• Locate the key HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionSL and then click on it.
• The DisableDnsPublishing subkey should be present and have a value of 1. If it is missing, create a DWORD value by right clicking DisableDnsPublishing, click Modify, in the Value Data box type in 0, and then click Okay.
