If a propsys.dll error occurs due to hardware failure, then it is advisable to update the drivers for hardware devices that you think are related to propsys.dll. For example, if you receive the propsys.dll error when you play a 3D video game, then try updating the driver for your video card.

It is no longer a secret that websites, social media, and other various places on WEB are tracking you and your messages and emails for keywords that they will later use to promote and serve your specific ads linked to those keywords. Altho the process is fully automated it does feel a little forced and uneasy. That is why we are bringing you this article in which we will show you how to stop website tracking in the most popular and used browsers.

SAFARI

Apple’s Safari browser gives you the option to block cross-site tracking. It also has a Privacy Report that displays all the sites and agencies that are gathering information about you. Before blocking these trackers, you may want to review exactly which sites are tracking you online and gathering information about you. Armed with this information, you may decide that cross-site tracking isn’t a huge issue for your particular browsing habits, or you may decide to avoid certain websites entirely. To access Safari’s Privacy Report:

1. Launch the Safari web browser.
2. In the toolbar, select Safari > Privacy Report.
3. Select the Websites tab. This will display information about all the websites that are profiling you.
4. Select the Trackers tab. This displays a list of all the trackers that are gathering information about you. This includes the companies that created these trackers and the number of times Safari detected these trackers during your browsing sessions.

You can also check how intrusive a particular website is by navigating to the website in question and then selecting the shield icon that appears alongside Safari’s address bar. You can then select Trackers on This Web Page, and Safari will display a list of all the trackers that are active on this particular webpage. Once you’ve seen all the websites and agencies who are tracking you, if you want to block these trackers:

1. In the Safari toolbar, select Safari > Preferences …
2. Select the Privacy tab.
3. Select the following checkbox: Prevent Cross-Site Tracking.

Safari will now prevent these trackers from following you across the World Wide Web.

CHROME

As you’re browsing the web, Chrome can send a request for websites not to collect or track your browsing data. It’s important to note that this is a request, so there’s no guarantee that every website will honor the request. Frustratingly, Chrome doesn’t provide information about the websites that are tracking you online. However, we still recommend enabling this feature, as it can help minimize the number of websites that are tracking your online movements:

1. In Chrome’s upper-right corner, select the three-dot menu icon, then Settings.
2. In the menu on the left, select Privacy and security.
3. Click Cookies and other site data.
4. Find the Do not track slider and push it into the On position.

Now Chrome will send a Do Not Track request to every website you visit. Since this is only a request, you may want to take additional steps to protect your online privacy. Ghostery is a Chrome extension that enables you to view and block online trackers. After installing Ghostery, you can view all the trackers that are active on a particular website:

1. Head to the site in question.
2. Click the Extensions icon in the Chrome toolbar.
3. Select Ghostery to see a list of all the trackers this extension has detected.
4. You can block all of these trackers by selecting the Detailed tab and then clicking Restrict site.

Repeat this process for every site you visit.

MOZILLA FIREFOX

Firefox has an Enhanced Tracking Protection feature that can block all the cross-site trackers identified by Disconnect. This feature can also preserve your online privacy by blocking social media trackers, fingerprints, and crypto miners, making this a great all-arounder for the security-conscious Internet user. Enhanced Tracking Protection should be enabled by default. However, you can verify whether it’s active for your particular Firefox installation by navigating to any website. Next, click the little shield icon that appears alongside Firefox’s address bar and you should see a message confirming that Enhanced Tracking Protection is enabled. If Enhanced Tracking Protection isn’t enabled, we recommend activating it:

1. In Firefox’s upper-right corner, select the three-line icon, then Preferences.
2. In the menu on the left, select Privacy & Security.
3. You can now select either Standard or Strict. Note that Strict may affect the functionality of certain websites, so it’s recommended you opt for Standard unless you specifically require a greater level of protection.

Similar to Chrome, Firefox can send a Do Not Track request. While you’re in the Privacy & Security menu, you may want to consider activating Mozilla’s Do Not Track feature.

OPERA

When you first installed Opera, it gave you the option to block trackers. If you didn’t take Opera up on the offer then, you can start blocking trackers now:

1. Along the left side of the Opera browser, click the cog icon. This opens Opera’s settings.
2. In the menu on the left, select Basic.
3. Find the Block Trackers slider and push it into the On position.
4. Blocking trackers can impact the functionality of certain websites. If you start noticing strange behavior on a particular website, you may want to add that site to your Exceptions list. By allowing this site to use trackers, you should be able to resolve any issues you’re experiencing.

To make an exception for one or more websites:

1. Launch Opera’s settings by clicking the little cog icon.
2. Navigate to Basic > Manage Exceptions.
3. Click Add and then type the address of the site where you want to permit trackers.

Repeat for all the sites that you want to add to your exceptions list.

Error 550 - What is it?

Error 550 is an SMTP (Simple Mail Transfer Protocol) outgoing server error code. It usually occurs when you try to send emails through your Outlook account and the email message encounters a relay error. The email returns back without being delivered with a 550 error message. The error message is prompted as either of the following:

"550 Requested action not taken: mailbox unavailable" "550 5 2 1 mail from refused spam site"

In other words, the error code 550 means that your SMTP server was not able to deliver the sent email to the user.

Solution

Error Causes

There are multiple reasons for this error message including:

• The email address was typed incorrectly
• Incorrect SMTP Server settings
• ISP placing restrictions for outgoing mails on the email server
• System infected by virus or malware

Further Information and Manual Repair Regardless of what the reason may be for the error 550 code occurrence, it is advisable to repair and fix the issue quickly to avoid inconvenience. You may not be able to send emails from your Outlook account if the error continues. This can cause great hassle in corresponding with others timely and may create a big communication gap. Here are some quick and efficient ways to resolve this issue on your system:

Solution 1:

There is no need to panic when you encounter error 550. Sometimes the error message may occur because you inserted the wrong/ incorrect email address of the recipient. In such a case, cross-check the recipient’s email address to verify if it is correct. If not, insert the correct address and try sending the email again.

Solution 2:

If the error still persists, try other methods to resolve it. Sometimes error 550 can also occur due to incorrect SMTP settings. Fix it to resolve the error. This can be done by opening your Outlook settings Tools and Accounts option. Now go to view/change the email account for the email account you are having problems with. After that check, the SMTP server is set to mail.yourdomain.com. Then click more settings and then click the outgoing server tab.

Hopefully, this will resolve the issue.

Solution 3:

Another reason for the error occurrence can be ISP blockage. When the junk email volumes increase, network administrators (the people who are responsible for managing ISP servers) place restrictions on SMTP email servers to prevent spam on their network. If this is the reason, contact your ISP administrator to resolve the issue.

A copy of Windows gets into a grace period when it is installed on a computer which means that you can use your Windows computer without any constraints on its feature. However, if you suddenly encounter an error code 0xC004F009 then this means that the grace period has already expired. In such cases, you will see the following error message on your screen:

“Error Code 0xC004F009, The Software Licensing Service reported that the grace period expired.”

One of the possible causes of this error is that it could be that the grace period has already expired way before the system was activated which is a result of which the system is in the Notifications state at this moment. The error code 0xC004F009 has something to do with MAK-enabled computers in an enterprise when it comes to Volume Licensing. One of the reasons that this error pops up is due to the possibility that the computer was not activated yet even when it was already connected to the Enterprise. Another most likely cause of the error is when the system was never connected with the Enterprise at all and the given grace period has expired before your computer system is activated. Whatever the real cause of this error, this post will guide you in fixing it. Just refer to the instructions given below to fix it.

Option 1 – Try activating Windows using the command-line tool

• First, you need to obtain your MAK key from the IT administrator.
• Once you have it, tap the Win + R keys on your keyboard and then type “cmd” in the field and hit Enter to open an elevated Command Prompt.
• After that, type this command and hit Enter to install the product key or replace the existing one: Slmgr.vbs –ipk <your mak key>
• Next, type another command and hit Enter: slmgr.vbs –ato
• Once you’ve executed the given commands, Windows should be activated after it connects to Microsoft servers and then gives it some time and try to check if error code 0xC004F009 is now fixed or not.

Option 2 – Try activating Windows using your mobile phone

Activating Windows 10 can also be done using your phone. Just note that you have to call Microsoft to do so.

• In the Start Search box, type in “Slui 4” and tap Enter.
• Next, select your country and click on Next.
• Keep the window open and call the toll-free number of the country you’re from.
• Afterward, a confirmation ID should be given by the automated system which you must take a note of.
• Finally, in the box on the window, type in the confirmation ID and click on the Activate button. That should do it.

Option 3 – Try to prolong the grace period

On the other hand, it is also possible for you to prolong the grace period but you might have to get another genuine Windows key for that. Before you proceed, you need to create a System Restore point first afterwards, refer to the steps given below to increase the grace period of the Software Licensing Service on your Windows 10 computer.

• Tap the Win + R keys to open the Run dialog box and type “Regedit” in the field then hit Enter to open the Registry Editor.
• After that, navigate to this registry key: HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionSetupOOBEmediabootinstall
• Next, change the value of the “mediabootinstall” key to “0”.
• Now open Command Prompt with admin privileges and then type this command and hit Enter: slmgr –rearm
• The command you just entered will add another grace period to your system activation. After that, you have to obtain a new key and then activate Windows.

Option 4 – Try running the Windows 10 Activation Troubleshooter

You can also try to run the Windows 10 Activation troubleshooter to help resolve the error code 0xC004F009.

• 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.

Creating a new Windows 10 account comes with options related to privacy. For instance, you will see the options to disable or enable Speech recognition, Find my device, Location service, Inking & typing, and many more. And if you often have to create a test account in Windows 10 v1809 and you don’t want to give this option, you can just disable the Privacy Settings Experience at sign-in on your Windows 10 PC using a couple of instructions given in this guide. To disable the Privacy Settings Experience, you can use the Registry Editor and the Group Policy Editor. But before you get started, you need to log in as an administrator. Moreover, it would also be better if you create a backup copy of the Registry files as well as create a System Restore Point before you make any changes. After you have those things covered, refer to the steps given below to disable the Privacy Settings Experience at sign-in on your Windows 10 PC. Since there are two ways to get things done, choose one option that you prefer.

Option 1 – via Registry Editor

• Tap the Win + R keys to open the Run dialog box and type “Regedit” in the field and hit Enter to open the Registry Editor.
• Next, navigate to this path: HKEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftWindowsOOBE
• From there, look for the OOBE value and if you can’t find it there, you can just create it. To do so, right-click on the Windows key and select New > Key, and then name it “OOBE”.
• After that, right-click on the OOBE value and select New > DWORD (32-bit) value, and name it “DisablePrivacyExperience”.
• Then double click on DisablePrivacyExperience and set its value to “1”.
• Now exit the Registry Editor and restart your PC for the changes to take effect.

Option 2 – via the Group Policy Editor

• 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.
• After that, navigate to this path: Computer Configuration > Administrative Templates > Windows Components > OOBE
• Next, look for a setting named “Don’t launch privacy settings experience on user login” located on your right-hand side and then double click on it and select Enabled.
• Now click on the Apply and OK buttons to save the changes made.
• Restart your PC.

When Windows 10 was introduced as an upgrade to Windows 7 and 8, a lot were thrilled because of its new features. One of the most interesting features that this has is the Microsoft Store. Just like in our tablets and smartphones, we can now download our favorite apps from a trusted source. Without the Microsoft store app, you can’t download any applications that you can use on your computer. But what happens if you can’t open your Microsoft Store or you accidentally uninstalled it? The most common error that users encounter when accessing Microsoft Store is the error code 0x80072efd. This error code appears when there is a problem with the internet connection. To resolve this, troubleshoot your modem by doing a simple power cycle. Turn off your modem and wait for a couple of minutes and turn it back on. It should refresh your internet. This works if there is really no problem on the Service provider’s side. Disable your Proxy server, if you are using one to access the internet. To do this, press Windows + R keys on your keyboard. Type “inetcpl.cpl” in the box and go to Connection. Next, click on LAN settings then tick on the box next to Automatically detect settings. Uncheck the box below Proxy Server Among the useful apps that came with the Windows 10 upgrade is PowerShell. It allows you to install and uninstall individual and all apps by using a series of commands. So you don’t have to worry if you can’t find your Microsoft Store or if you accidentally delete it. To access PowerShell, type in the word PowerShell into the search box found beside your Window Icon. Look for PowerShell from the results and right-click on it and hit Run as Administrator.

When you are in the PowerShell window, enter the command below:

Get-AppxPackage -allusers Microsoft.WindowsStore | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)AppXManifest.xml"

Another option is to download a Windows Update Troubleshooter. After you download it, open the troubleshooter tool and follow the steps. If you saved the file instead of directly opening it, go to the folder where the troubleshooter was saved and double click on the wu.diagcab file to rub the troubleshooter. One of the most interesting error codes that you might encounter when accessing the Microsoft store is error code 1. This particular error code is resolved by changing your PC’s region to the United States. To do this, go to Settings and look for Time & Language. Then go to region and language. Under the Country or region, choose the United States from the dropdown menu then restart your computer. The troubleshooting procedures above are the most common solution to resolve the problem on Microsoft Store issues but there are times that these procedures won’t work. If you are not confident to resolve this through the procedures mentioned in this article, there are so many tools online that you can download to help you out. It also helps to contact Microsoft or consult a technician to ensure that you are doing the correct procedure.
