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.

What is Mastodon? Mastodon is an open-source microblogging network very similar to Twitter. You can make 500 characters post messages called toot (tweet), share videos or images, and follow other people. But unlike Twitter, Mastodon is decentralized, meaning the entire Mastodon is not run by a single company pulling all strings.

Mastodon can be used directly in your web browser or through a mobile client on a smartphone or tablet. It includes features that seem copied from Twitter-like replies, boosts (retweets), favorites (loves), a timeline view, blocking, and voluntary content warnings that hide sensitive content.

Mastodon also has some great features that Twitter does not have like automated post deletion for the older post of a certain age, requiring approval for follows without restricting your account, and opting out of search engine indexing.

Currently, there are also no ads on Mastodon meaning no ad tracking or ad network surveillance.

How Does Mastodon Work?

Mastodon is a social media network made of nodes called servers or instances each running special software meaning anyone can run their own Mastodon instance (if they have a proper dedicated server). When you have your own instance it can be linked in the federation or remain private, so individuals or companies can have control over individual Mastodon servers.

The software itself is open source based on the social networking protocol ActivityPub which was developed by WWW Consortium.

While using Mastodon, people sign up for accounts with specific instances. Once logged in, you can view a local timeline (of posts from that instance only) or, if the instance is federated with others, see a federated timeline comprised of toots from people in other instances. Mastodon users can send messages to each other using their Mastodon account names that are similar to email addresses in that they feature the server address as well as the user name.

In case you didn’t know, the new Windows 10 v1903 has brought tons of new features around Windows 10 Updates. One of these features is the ability to automatically adjust the Active Hours based on your computer activity. This feature is really useful as it tells the operating system when to install the Windows Updates. A lot of users use the Active Hours feature to ensure that the Windows Update won’t force them to restart their PCs to install the update. So if your computer is turned on, it won’t apply the update during the active hours you’ve specified. In addition, the active hours change for many users and they are not that strict. For instance, if you set the active hours between 10 am to 5 pm, Windows Update won’t be forcing you to restart your computer to install the updates at those times. Note that Windows Update allows enabling an option using where it can monitor the active hours in your computer and change it. To configure this setting, here’s what you have to do:

• Frist, go to Settings > Update & security > Windows Update.
• Next, take note of your current active hours and click on the “Change active hours” link.
• Then toggle the option that says, “Automatically adjust active hours for this device based on activity”. This will change the active hours and if you match it with the previous one, it should be different.

As you can see on the image given above, the earlier active hours were between 8:00 to 17:00 and were changed to 11:00 to 19:00. If you have been using this feature for a while you’ll find how useful and handy it is especially when you’re using your computer and don’t want any notifications like the prompts for Windows Updates to bother you while working.

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

Recently, a number of users reported that they were not able to use the “Run as administrator” context menu option when they tried using it or opening a program with administrator privilege. If you are one of these users facing this problem, then you’ve come to the right place as this post will guide you in fixing this issue. At the time of writing, it isn’t clear what the cause of the issue is but there are potential fixes you can try to fix the problem. You can try turning on the User Account Control or clean up the Context Menu items change the Group Membership. On the other hand, you can also perform both SFC and DISM scans via Command Prompt or troubleshoot the problem in a clean boot state as it is possible that some third-party programs are the ones that are causing the problem. You could also run an anti-malware scan using Windows Defender or your antivirus program.

Option 1 – Try to turn on the User Account Control

When you open a program with administrator privilege, the User Account Control or UAC prompt will pop up asking you to confirm the permission. However, if you have disabled the User Account Control by mistake or some malware has disabled it, then it’s no wonder why the “Run as administrator” option is not working. Thus, you need to check if UAC is turned on or not. All you have to do is go to the User Account Control settings.

Option 2 – Try changing the Group Membership

• First, you need to sign in with your administrator account or ask your administrator to sign in for you. So if you only have a Standard User account, you have to add that account to the Administrators group.
• In the taskbar search box, type “netplwiz” and check the search results.
• From there, select your user account and click the Properties button.
• After that, go to the Group Membership tab and select Administrator.
• Now click on the Apply and OK buttons to save the changes made and then sign in to your computer again and see if the “Run as administrator” option is working or not.

Option 3 – Try to create a new Administrator User account

If you have a standard account, you can try creating a new account but this time, you create an administrator user account and then see if you can now use the Run as administrator option or not. Note that you have to sign in with your main account before you can create an admin account.

Option 4 – Run the DISM tool

You can run the DISM tool as well to help fix the problem with the “Run as administrator” option. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth”.

• 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.

Option 5 – Perform a System File Checker scan

The SFC or System File Checker scan could detect and automatically repair damaged system files that could be causing the problem with the “Run as administrator” option on your Windows 10 computer. 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 and hit Enter.

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.

• Once done, restart your computer.

Option 6 – Put your computer in a Clean Boot State

You can also troubleshoot the problem in a Clean Boot state. It could be that there are some third-party applications in your computer that are preventing you from using the “Run as administrator” option and to isolate this possibility, you need to boot your computer in a Clean Boot State and then try to use the Run as administrator again. Putting your computer in this state can help you identify which program is the culprit and thus isolates the problem. In a Clean Boot state, your computer will start using only the pre-selected minimal set of drivers and startup programs. Note that you have to disable and enable one process at a time.

• 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 you’ve set your computer into a Clean Boot State, try to check if the error is now fixed and that you can now view the Properties.

Option 7 – Try scanning your computer using Windows Defender

As mentioned, if your computer was recently infected with some malware, it is possible that the malware changed the User Account Control settings which is why you’re not able to use the Run as administrator option. Thus, you need to scan your computer using Windows Defender.

• Tap the Win + I keys to open Update & Security.
• Then click on the Windows Security option and open Windows Defender Security Center.
• Next, click on Virus & threat protection > Run a new advanced scan.
• Now make sure that Full Scan is selected from the menu and then click the Scan Now button to get started.
