How to run old applications in Windows 10

One of the most sophisticated Artificial Intelligence or AI assistants there is in the market is Cortana. However, no matter how sophisticated this AI assistant may be, there are still times when you encounter issues with it. So if your Cortana is not connecting to the internet, worry not for this post will guide you in fixing the problem. This connection issue in Cortana might have something to do with the settings, network connectivity, or your Microsoft account. In addition, it could also be that the Firewall or antivirus program interferes with its connection. Whichever the case is, here are some possible solutions that could help you resolve the problem.

Option 1 – Try to power cycle the modem, router, and computer

• Connect the modem, router, and the PC hard-wired and then switch all of these three devices off.
• Turn on the modem and wait for 30 seconds.
• Turn on the router and wait for 30 seconds as well.
• Finally, turn on the computer and check if you can now successfully connect to the internet.

Option 2 – Check if your router or ISP is properly working

Since the basis for this issue is that Cortana is not connecting to the internet even though you are able to access websites using your browser, you might want to check your router or ISP (Internet Service Provider) and see if they’re functioning properly.

Option 3 – Try changing your internet connection

You can also try changing your internet connection and see if it fixes the problem. If you are using Ethernet, you can try connecting to a Wi-Fi connection and see if Cortana is able to connect or not.

Option 4 – Try to run the Search and Indexing troubleshooter

You might also want to run the Search and Indexing troubleshooter in Windows 10 as it checks whether the settings for Cortana are in place and automatically corrects any issues if the update or software installation has changed the settings. To run it just click on the Start button and select Settings > Updates and Security > Troubleshoot. From there, select the Search and Indexing Troubleshooter. Note: You can also run the Network Troubleshooter as it can also help in resolving the issue especially if the problem is in the network.

Option 5 – Try to remove Proxy

Removing the Proxy might also help you in fixing the connection issue in Cortana. Here’s how you can do it:

• 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.

• Restart your PC.

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

Option 6 – Verify your Microsoft account

In some cases, Cortana might not be able to connect to the internet because your Microsoft account is no longer verified. This usually happens when you use a two-step authentication system with your Microsoft account. To verify it, just open Settings and click on Accounts. After that, check if you have a Verify hyperlink under your Microsoft account or not then click on Verify. Afterward, follow the next on-screen prompts to verify your Microsoft account. Once your account is verified, restart your computer.

Option 7 – Try resetting Cortana

• Open Cortana and go to the Settings section where you’ll see the “Turning off Cortana clears what Cortana knows on this device, but won’t delete anything from the Notebook. After Cortana is off, you can decide what you’d like to do with anything still stored in the cloud” option. Turn this option off.
• Restart your PC.
• After your computer boots, launch Cortana again and check.

Option 8 – Try to reinstall Cortana

If none of the options given above works, you must consider reinstalling Cortana.

Internet connectivity issues like Can’t connect to this network present a complex problem with simple solutions for PC and laptop users. First, it is usually recommended that users rule out problems with the internet connection, router, and Wi-Fi settings before proceeding to troubleshoot settings on your PC/laptop. Once the rest are ruled out, we can then proceed with the following troubleshooting steps and guidelines to fix your wifi connection issue: The first step is to update your windows network adapter driver. Connectivity problems may arise if your network driver is not updated or if it is incompatible with the network adapter. To do so, you may resort to any third-party driver scanning and installing programs found online. This solution should resort if users don’t want the hassle of perusing through windows settings that users may not be familiar with. However, this solution requires a pre-existing internet connection other than wifi, so it is recommended you have a backup internet connection via ethernet. The second step is to uninstall the driver for your network adapter. This solution is to resort if there is an issue with the driver as restarting the PC after the following steps let windows reinstall the driver again:

• Open the quick access menu on your keyboard by pressing the Windows key and X key at the same time and select “Device Manager” from the menu list.
• From the list of devices, select “Network Adapters”
• Usually on the top of the list is the Wireless Network Adapter
• Right-click the Wireless Network Adapter and select the option to “Uninstall device”
• You will be given a confirmation in a new separate window to proceed. Click “Uninstall” to proceed.
• After completing the previous steps, try rebooting your Windows PC and reconnecting to see if it works.

A third step is to disable the 802.1 1n modes of your network adapter by following the next steps:

• First press the Windows logo key and the X key at the same time to bring up the quick-access menu. And like the previous step, select “Device Manager”
• From the list of devices, select “Network Adapters”
• Right-click the Wireless Network Adapter from the drop-down menu and select properties
• Under properties, select the “Advanced” tab then select the 802.1 1n Mode. To the right drop-down menu change the option to  “Disabled” and click “Ok”
• After, try to re-establish the connection to see if the steps have worked.

In the event that any of the preceding did not fix your problem, it helps to take a second look at the router and network settings using the interface provided by your ISP. A simple reset to the back of your router often fixes the issue. Also, try to check if you have any other administrative capabilities over the network to determine whether your device, in particular, has been MAC filtered or if the frequency of your wireless adapter is not compatible with the broadcast frequency of your router.

No one knows everything about a program off hand. You need to use the program for a long time before you can even possibly know all that it is able to do and all you are able to achieve with it. However, this doesn’t mean that you don’t need help from time to time. This is also the case when Outlook errors pop up. Sometimes there are things you must or probably should do with your program that you do not understand and definitely don’t know how to do. Set up POP3 with your email account in Outlook is one of these things you will probably need help to achieve.

Steps to Set up POP3

First, you may need to know what POP3 is. POP3 is the way emails are sent from one email address to another. It may be more or less instant nowadays, but the process is still long and hard-winded. Similar to how your letters get from your mailbox to the recipients' mailbox, your emails get from you to the next person. Letters are picked up in your mailbox and sent to your post office where they send it to the recipient’s post office who sends it to the recipient’s mailbox. Similarly, your email is sent to your outbox, which sends it to your email service provider, that sends it to the recipient’s email service provider who sends it to their inbox. This is one of the reasons that sending an email to someone who uses the same email service provider as you is about a millisecond faster. This process of sending emails is called POP3 and you need to set it up if you use Outlook on Microsoft. This, on Outlook, also determines which email account you send your emails from. You see, on Outlook and many other email service providers, you can have many different email addresses, no even necessarily with the email service provider’s prefix on the end. Now, if you want to see this for yourself, go on to your settings on Outlook and look for manage email accounts. If you have more than one email account, you will see them listed. Somewhere on the sidebar, you will see POP3 as well. If you want to add more email accounts to this, such as a business email or a personal email, then just click ‘Add new account’ instead of 'Manage email accounts'. When you click on an email account you have linked already, you will see on this side the details for your POP3 (incoming emails) and your SMTP (outgoing emails). This can be changed, but since everyone’s number of accounts and type of accounts is different, there is no set way to change this. However, you can give Microsoft a call and they will walk you through the necessary steps in order to change this.

Conclusion

So, POP3 can be incredibly easy to understand or incredibly hard; it depends on how good you are with electronics and the advice you are given. But don’t try to change things by yourself; get a professional from Microsoft to help you with POP3 on your Microsoft Outlook account.

If you suddenly encounter the SYSTEM_PTE_MISUSE – 0x000000DA Blue Screen error while using your Windows 10 computer, read on as this post will provide you some potential fixes to resolve this kind of Blue Screen of Death (BSOD) error.

Scammers have decided to target Windows’s 10 App installer process in order to infect your computer and steal your data. As in most usual online scams, everything starts with a strange email containing threats and other poorly written and composed speech. At the end of the given email, there would be a link claiming that you, of course, need to read it and follow instructions about the threat, if you click the link it will open a web page where you will have an innocent-looking PDF file with more information about the threat itself. If you click on a seemingly innocent PDF file it will summon Windows 10's AppInstaller.exe tool, kickstarting a download-and-run process that'll put you in a bad place very quickly. From there, you'll have to deal with the dangers of malware BazarBackdoor, including data and credential theft. This kind of scam is nothing new but the interesting thing here is that it uses App installer and by clicking on a link you are opening and giving permission for a malicious crook to use it. So, stay safe and do not click on any links from unknown emails no matter what.

If you are trying to log into your user account on your Windows 10 computer but encountered an error message instead that says, “Your account has been disabled, Please see your system administrator”, read on as this post will guide you on how you can fix this problem.
