You can set Windows 10 to Automatically save your restartable apps when you sign out and restart them after you sign in. Here’s how:

1. Right-click on the Windows logo to open the secret menu
2. Select Settings

When performing a Windows Backup to the NAS device (backup to a network share) that is running Samba, fails with an error message The backup failed, The version does not support this version of the file format (0xC03A0005). The problem occurs because of a conflict with the VHD file that is created by Windows Backup and is mounted during the process. There are three types of VHD files:

1. Fixed,
2. Expandable
3. Differencing

If the VHD file is a sparse file that is not supported by the native VHD driver, the mounting will fail, and you will get this error. An example VHD file is one that keeps expanding depending on the backup size. The problem occurs only in the case of  File Level backup (file/folders in a volume) but not on the block level backup as the vhd file is never mounted. However, in the case of File Level Backup, the vhd is mounted, created by Windows Backup, which does not support the mounting of sparse files.

The solution is to use Strict Allocate: option in the smb.conf file

Login to SMB using SSH. Open the configuration file using the VI editor located at /etc/samba/smb.conf. If the option is not there, you can manually add strict allocate = yes which will make sure there are no sparse file that is created.

One of the smoother things that Microsoft did with the Windows 10 operating system is to separate Cortana from Search. This means that Cortana is strictly now a voice assistant and many users have seen it coming since not everyone uses Cortana. In addition, it also paved the way for other virtual assistants like Alexa to get on board with Windows 10. And now in the newly released Windows 10 v1903, Windows has brought the Voice Activation under Privacy. In this post, you will be guided on how to perform the Voice Activation troubleshooting on your Windows 10 computer. To use Voice Activation in Windows 10, follow, in the Start Search, type “voice activation” and click on “Voice activation privacy settings” listed in the search results. And from there, you can choose to allow apps to use Microphone, like listen in the background as well as select which app can access it. Each time enabled voice assistants continue to listen via microphone for the voice keyword, the app will activate itself for the keyword and will react depending on what you ask it. So if you are using a voice assistant and it didn’t respond when you speak the keyword, just go to Settings > Privacy > Voice Activation and follow these steps:

Option 1: Check the App permission to use the voice activation feature.

You have to make sure that the toggle button for the Voice activation feature is turned on globally. It can be found under the “Allow apps to use voice activation” section. You also have to ensure that the microphone is available for apps that use this feature.

Option 2: Voice activation is not working under the lock screen.

If you tend to use the voice assistant even when your computer is locked, Microsoft has a specific setting that you have to turn on. You need to make sure that the toggle button for the “Allow apps to use voice activation when this device is locked” option is turned on. However, keep in mind that the voice assistants are not locked to only recognize your voice as they also answer to anyone who will use the voice keyword.

Option 3: Check the individual permissions of apps.

If the voice assistant is not working, you have to check each one of the apps’ permissions for voice keyword, and the option to work under locked condition works.

Option 4: Run the Microphone troubleshooter.

If you’ve verified that the settings are in place, then you have to run the Microphone troubleshooter by simply going to Settings > Privacy > Microphone. From there, make sure that the toggle button for the following options is turned on:

• Allow apps to access your microphone
• Enable microphone access for the voice assistant

And if it’s a desktop app, you have to enable the toggle on at the end.

Error Code 0x80072efe - What is it?

Error Code 0x80072efe is a fairly common error code that generally occurs in Windows 10. It is most often associated with the process of performing updates using the Windows Update tool.

Common symptoms include:

• Inability to install or complete updates on your Windows machine
• Computer freezing as programs are run or started
• Inability to perform installations of downloaded programs
• Programs crashing or failing to work properly

While Error Code 0x80072efe can cause a number of frustrating issues on your device, the good news is that there are several methods that can be used to fix this error. The two most common methods are actually fairly easy to perform and do not require advanced tools or knowledge. However, if you don’t feel like you will be able to perform the necessary steps on your own, be sure to get in touch with a qualified computer repair technician to help you in the resolution of this particular error.

Solution

Error Causes

Two things are generally behind the appearance of Error Code 0x80072efe on a Windows device. The first is that one or more of your registry keys are not available, have been corrupted, or are not installed properly. The second is that necessary DLL files aren’t working properly within your machine.

However, other things can mimic these causes, which is why the two methods listed below will resolve the issue in most cases.

Further Information and Manual Repair

Fortunately, there are two resolution methods that can be used quickly and easily when Error Code 0x80072efe arises on your Windows computer. Neither of these requires advanced knowledge or skill, but if you don’t feel comfortable with performing these steps on your own, it is recommended that you contact a qualified computer repair technician in order to get assistance.

Here are the best ways to resolve Error Code 0x80072efe on your computer:

Method One:  Check Your Time and Date Settings for Accuracy

If your time or date has been set incorrectly, it can make your system logs appear to have incorrect information, which can lead to the appearance of Error Code 0x80072efe. Because this is the easiest thing to fix if it is indeed the problem that is making the error code appear, this should always be the first thing that you try when this error code arises.

In order to check your time and date settings, follow these simple steps:

• Step One: Make sure that you are logged into your computer as an administrator.
• Step Two: Click on the time and date listed on the lower right edge of your screen. If the settings are not correct, choose the option to change the time and date.

If method one has not successfully resolved Error Code 0x80072efe, you may need to attempt method two.

Method Two:  Check Your Firewall Settings During Updates

In some cases, your firewall can prevent your machine from accessing the information that it needs in order for the installation or update to go through correctly. If that is the case, you can follow a few simple steps to turn off your firewall, just while you install the update, and then turn it back on.

In order to do so, follow these steps:

• Step One: In the Start menu, choose the option to open the Control Panel.
• Step Two: Select the option for System and Security, looking for and clicking on Windows Firewall.
• Step Three: Turn off any private network firewalls.

Note that if this method allows you to successfully bypass the error code, you’ll need to make sure to turn the firewall back on when you are finished. Even though it can interfere with the Update process, your firewall is still very important to your computer.

Method Three: Use An Automated Tool

If you wish to always have at your disposal a utility tool to fix these Windows 10 and other related issues when they do arise, download and install a powerful automated tool.

Error Code 0x800CCC0E - What is it?

The error code 0x800CCC0E is an Outlook error that appears while using either Microsoft Outlook or Outlook Express. The error message hampers your ability to send and receive emails.

Solution

Error Causes

0x800CCC0E Outlook error code is triggered by multiple reasons including:

• Improper connection with SMTP (Simple Mail Transfer Protocol) server
• Damaged files
• Registry corruption

In most cases, it’s the registry that gets corrupted which leads to the occurrence of 0x800CCC0E error code display. This typically happens when you try to update your Outlook/Outlook Express version. When updating, you need to remove all the software files of the previous Outlook version which includes the registry too. If the files are not removed from the registry, the new version update will often fail. The junk files of the old version are likely to damage and corrupt the registry.

Further Information and Manual Repair

It is advisable to repair the error code 0x800CC0E right away to avoid inconvenience and system failure and fatal crashes which can lead to valuable data loss.

Cause: Improper connection with SMTP (Simple Mail Transfer Protocol) server

Solution: If the cause of the 0x800CCC0E is SMTP server connection failure, then the best way to resolve the error is to reconfigure your email account settings. Make sure that port 25 is being used in the SMTP area. Port 25 is the standard outgoing mail port. If the SMTP setting is on port 25 then another reason for the error 0x800CCC0E can be your anti-virus or firewall software enabled on your PC. Turn it off for a moment and then try sending emails from your Outlook.

As you know, Microsoft constantly releases new updates with the main goal of fixing bugs as well as deliver users with new and exciting features. However, there are times when the latest update comes with an unwanted bug. One of these bugs is an error message saying, “Low Disk Space. You are running out of disk space on Local Disk (G:). Click here to see if you can free space on this drive.” So if you have recently installed a Windows 10 update, then you’ll most likely see a completely new drive on your computer which will appear right after the installation of the update and you’ll also start seeing the aforementioned error message. It gets irritating as this error message keeps on popping up even if you still have a lot of free space on your other drivers. Obviously, the main reason why this error message pops up all the time is the bug brought along by the Windows Update. This bug unhides the recovery partition drive and allocates it a drive letter which is why you are seeing a new drive in your computer. Thus, you can get rid of the pesky error message by simply removing the letter of the new drive. Just remember that you must not delete anything from the recovery partition drive nor format the drive. Formatting or deleting the recovery partition drive can heavily affect the recovery of Windows since the data on the drive is used by the Windows Recovery Environment or your system’s manufacturer. A lot of users have reported that removing the drive letter has resolved the issue. And if you worry that removing the drive letter will delete the drive, you are mistaken. This solution is basically harmless and is proven effective to make the notifications go away. Carefully follow the instructions below to get rid of the Low Disk Space notification by removing the drive letter.

• Step 1: Tap the Windows key once.
• Step 2: Next. In the Windows Start Search, type in “command prompt” and right-click on Command Prompt from the search results and select the “Run as administrator” option or you could simply tap Win + R keys and then input “cmd” and hit Enter to open Command Prompt.
• Step 3: After opening Command Prompt, type in “diskpart” and tap Enter.
• Step 4: Next, type in “list volume” and tap Enter. After that, you will see a list of drives.
• Step 5: Take note of the letter associated with the newly created drive.
• Step 6: Afterwards, type in “select volume <drive letter>” and tap Enter. Take note that you must replace the <drive letter> with the drive letter you’ve found in Step 5.
• Step 7: Now type in “remove letter=<drive letter>” and then tap Enter. Once again, replace the <drive letter> with the letter you took note of in Step 5.

ExpressFiles is a program developed by Express Solutions. A number of Anti-Virus programs have flagged this program as a Potentially Unwanted Application. In many instances, it is bundled with additional programs on installation.

The program claims it offers users easy to search for various currently popular search terms. During our testing, the software never displays any search results, no matter the search words. Upon installation and setup, it defines an auto-start registry entry which makes this program run on each Windows boot for all user logins. A scheduled task is added to Windows Task Scheduler in order to launch the program at various scheduled times. The program defines an exception rule in Windows Firewall, allowing it to connect to the internet without limitations and auto-update itself.

About Browser Hijackers

Precisely what is a PUP?

If you’ve ever downloaded a free application or shareware, chances are high that the computer can get installed with a bunch of unwanted applications. A PUA / PUP (potentially unwanted application / potentially unwanted program) is a software program that comes bundled with free software and you consent to install it on your PC. These are programs you almost certainly don’t want on your computer simply because it doesn’t give any valuable service. Despite being regarded as very detrimental, PUPs aren’t always viruses or malware One simple difference between PUP and malware is distribution. Malware is normally dropped by silent installation vectors like drive-by downloads while PUP gets installed with the consent of the computer user, who purposefully or unknowingly approves the PUP installation on its PC. Having said that, there is no doubt that PUPs remain bad news for PC users as they can be incredibly damaging to the computer in numerous ways.

Exactly how do unwanted programs look like?

Potentially Unwanted Programs appear in different forms and varieties, however, in the majority of instances, they are adware programs that exhibit irritating pop-up ads and advertisements on websites you explore. In addition, the majority of free programs these days come with some unwanted add-ons; in most cases an internet browser toolbar or browser modification like a homepage hijacker. They’ll keep track of your online routines, redirect your search results to risky websites where viruses can be downloaded and installed, hijack your home page, and slow your browser down to a crawl. Potentially Unwanted Programs occasionally act quite much like computer viruses or spyware. They might carry keyloggers, dialers, browser hijackers, and tracking components that gather system details, or tracks customer habits and relays this information to third-party firms. Even if the PUPs really aren’t basically malicious, these software programs still do absolutely nothing good on your personal computer – they will take valuable system resources, slow down your PC, weaken your computer security, and make your system more susceptible to trojans.

How do you avoid PUPs?

• Read cautiously before accepting the license agreement as it may have a clause about PUPs. • Always opt for the custom if you’re presented an option between “Custom” and “Recommended” Installations – never click Next, Next, Next blindly. • Have a top-notch antivirus program like Safebytes Anti-Malware which can protect your computer from PUPs. As soon as you install this software, protection from malware and PUPs is already switched on. • Think carefully before you download any kind of shareware or freeware. Disable or get rid of toolbars and browser extensions you don’t really need. • Only use official product websites for downloading programs. Stay away from download portals altogether as most websites compel users to download the software using their own download manager, which is often bundled up with some sort of PUPs.

What To Do If You Cannot Install Any Anti-Malware?

All malware is bad, but certain types of malicious software do a lot more damage to your computer than others. Some malware types modify browser settings by adding a proxy server or modify the PC’s DNS settings. In these instances, you will be unable to visit some or all of the websites, and therefore not able to download or install the required security software to remove the infection. If you are reading this right now, you have perhaps recognized that a malware infection is a reason for your blocked web connectivity. So how to proceed when you want to install an anti-malware application like Safebytes? Follow the instructions below to eliminate malware by alternative methods.

Install in Safe Mode

The Windows-based PC comes with a special mode called “Safe Mode” where just the bare minimum required applications and services are loaded. If the malware is set to load immediately when the computer starts, shifting to this mode may well prevent it from doing so. In order to enter into Safe Mode or Safe Mode with Networking, press the F8 key while the PC is starting up or run MSConfig and locate the “Safe Boot” options under the “Boot” tab. As soon as you restart the PC into Safe Mode with Networking, you could download, install, and update anti-malware software from there. Right after installation, run the malware scanner to get rid of standard infections.

Utilize an alternate internet browser to download antivirus software

Web-based malware could be environment-specific, targeting a specific web browser or attacking particular versions of the web browser. If you’re not able to download the anti-virus application using Internet Explorer, this means the virus is targeting IE’s vulnerabilities. Here, you need to switch to a different web browser such as Chrome or Firefox to download the Safebytes Anti-malware program.

Install and run antivirus from a Thumb drive

Here’s yet another solution which is creating a portable USB anti-virus software that can scan your computer for malware without the need for installation. Try these simple actions to clean up your infected computer using portable anti-malware. 1) Download Safebytes Anti-Malware or Microsoft Windows Defender Offline onto a clean PC. 2) Mount the pen drive on the same PC. 3) Run the setup program by double-clicking the executable file of the downloaded software, which has a .exe file extension. 4) Select the drive letter of the USB drive as the location when the wizard asks you exactly where you would like to install the anti-malware. Follow activation instructions. 5) Now, insert the thumb drive into the corrupted PC. 6) Run the Safebytes Anti-malware directly from the pen drive by double-clicking the icon. 7) Click the “Scan” button to run a full computer scan and remove viruses automatically.

Hello and welcome to our Business Email Etiquette. Most people have experience in writing emails at some point before in their lives. However, the emails an average person writes are probably personal emails and not mails for work purposes. Emails you send to friends are incredibly different in content and context to business emails you would send to customers or employers or even other colleagues in your workforce. So, if you have a job that involves you writing emails to people in business style, learning business email etiquette is an absolute must for you.

 1. Heading layouts

When you are sending emails to friends, you generally lay them out like a memo. This means there is very little detail in the layout besides basic greetings and paragraphs, usually starting with the greetings. However, with a business email, it is best to lay it out exactly like you would lay out a formal letter. You need to put the company’s address in the right-hand corner and the date as well. Only then must you go on to the greetings. This will make your email look more formal, making you seem like a professional who knows what they are doing as opposed to someone who just couldn’t be bothered spending the extra time to get the layout right.

 2. Proper greetings

 When you are sending an email to a friend, you usually greet them informally. If their name was Mary Johnson, you’d probably start your letter with a ‘Hey Mary’ or a ‘Hello Mary.’ However, this is not considered a professional way to write an email to a customer or other important person in your business. Again, you must use the proper method that you would greet someone with were you writing them a formal letter instead. If your customer is Mary Johnson again, you should greet her with respect. ‘Dear Ms. Johnson’ would be the most appropriate way to start off your letter’s actual body in this case. If you do not know the recipient’s name, then you should start with a simple ‘Dear Sir or Madam.’ Politeness will always get you incredibly far, no matter what line of work you are in.

 3. Informal language

 You should get straight to the point with your email. Don’t dawdle on with it like you would if chatting to a friend and don’t write it how you would speak either. You use language that sounds impressive and smart while not using such obscure language that your recipient doesn’t know what you are saying. All the time, you must keep it informal where possible, possibly even impersonal as well. It will make you seem very professional in the long run.

 4. Signing off

When you are sending your email, you must end it as you would with a letter also. Don’t just say ‘Bye’ and your first name; that is too personal. You need to say ‘yours sincerely if you know the name of the recipient and ‘yours faithfully’ if you do not. Then you should end with your full name and whatever position you have at the company. (CEO, technical staff etc.) So there you have it! All you need to do now is to show your boss that you can handle the emails from now on!

If you suddenly encounter Activation Error codes such as 0xC004E016, 0xC004F210, 0xC004F034, and 0xC004F00F on your Windows 10 computer, then they all point to the same issue – Invalid Product Key or Version mismatch. When you see any of the aforementioned error codes above, it indicates that you are either entering a wrong product key or you are using an incorrect ISO when installing it on your computer. In such cases, you may see either of the following error messages:

“You are running Windows 10 Pro, but you have a valid digital license for Windows 10 Home.” Or: “The specified product key is invalid or is unsupported by this version.”

If you got the error code 0xC004F00F then it means that you’ve entered a product key for the Enterprise edition of Windows to activate Windows 10 Pro or Windows 10 Home. It could be that you have a key from your work and you accidentally use it on your Home PC. If you got the error codes 0xC004E016, 0xC004F210, then it means that you have entered a product key that is meant for a different edition or version of Windows. On the other hand, if you got the error code 0xC004F034 instead, then it means that you have entered an invalid product key or a product key for a different Windows version. Whichever error codes you have, refer to the possible solutions given below to fix the Invalid Product Key or Version mismatch Activation Error in Windows 10.

Option 1 – Try running the Windows 10 Activation Troubleshooter

The first thing you can do to resolve this Activation error is to run the Windows 10 Activation Troubleshooter. To do so, follow these steps:

• 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.

Option 2 – Try purchasing a new license

There is an exception offered by Microsoft – if you are connected to a Microsoft account prior to the hardware change, then you can most certainly use the same license key to reactivate Windows 10 again. Microsoft calls this an “Exception path” which should be fixed easily by the Windows Activation Troubleshooter as pointed out earlier. However, if the Windows Activation Troubleshooter isn’t able to resolve the error you can try purchasing a new license. In such rate case, even if you do have a Microsoft account available on your Windows 10 computer, and if Windows was never activated, this solution will not work. And if you haven’t connected your Microsoft account with your Windows 10 computer prior to the major hardware change, then your only option left is to purchase a new license. For you to do that here are some steps you can follow.

• To purchase a new Windows license, the first thing you have to do is click on the Start button > Settings > Update & Security.
• From there, go to Activation and select the “Go to Microsoft Store” option.
• After receiving your new license, you need to go back to Update & Security then go to Activation and select the “Change product key” option.
• Now update your Windows 10 computer using the new key and it should automatically activate your computer.
• Next, you have to create a Microsoft account or connect to your existing local account to your online account.
• Once the system links the key and the account, you need not buy a new license in case something like this happens again.

Note: If you are an IT administrator, you need to keep in mind that there is a limit to the number of times you can reactivate Windows on your computer. Moreover, if you don’t see any option to reactivate the license, and it is a work computer, you need to contact your organization’s tech support.

Option 3 – Try activating Windows 10 via 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.
