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. See if the ‘My server requires authentication for the outgoing server’ is checked. If not, then check on it. Then simply save to confirm changes. Now try emailing again. 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.

We couldn’t update system reserved partition” - What is it?

Customers will most likely encounter the “We couldn’t update system reserved partition” error when upgrading to Windows 10 from Windows 7 or Windows 8.1. This error may also come with error code 0xc1900104 or error code 0x800f0922.

Solution

Error Cause

“We couldn’t update system reserved partition” Windows 10 upgrade error is normally caused by too little space on the System Reserved Partition (SRP). The System Reserve Partition is an additional small partition created by Windows, which stores boot files. The SRP can be filled up with security apps and third-party anti-virus. Once this partition has insufficient space, the system will not be able to upgrade to Windows 10.

Further Information and Manual Repair

Caution: The following steps are complex and need to be done by experienced users especially using the command line. Once an error is made in entering commands, there’s a chance that your device can be put in a no-boot situation, or data stored on the device can possibly get lost.

To upgrade to Windows 10, your device needs to have at least 15MB free space on the System Reserved Partition. Follow the procedure below and then try upgrading again.

First, know if the System Reserved Partition is whether in GPT or MBR partition style:

1. Open the Run window by pressing the Windows key + R. Type msc in the window then press Enter.
2. Right-click on the Disk where SRP is located then select
3. Click over the Volumes
4. On the Partition Style line, you’ll see which partition style your device is using, either Master Boot Record (MBR) or GUID Partition Table (GPT)

Second, determine which method you will need:

Depending on what partition style your device has and whether you’re currently on Windows 7 or Windows 8/8.1, there are various methods you need to do.

Method 1: Windows 7 or 8/8.1 with GPT partition

1. Click on the Start button and search for cmd. In the results, right-click on Command Prompt then choose Run as administrator. The command prompt window will appear.
2. Type mountvol y: /s at the command prompt then press Enter. This command will add the Y: drive letter where you can access the System Partition.
3. Type taskkill /im explorer.exe /f then hit Enter. Afterward, restart explorer in Admin mode by typing exe and hitting Enter.

NOTE: While in Admin mode, some apps like OneNote will not run.

4. Open File Explorer then type Y:EFIMicrosoftBoot in the address bar. Hit Enter.
5. Choose the language folders you want to permanently delete. Language folders are named with four letters split with a hyphen. For instance, you want to delete the German language: choose de-DE.
6. Optional: You can also delete unused font files for more space. Type Y:EFIMicrosoftBootFonts in the address bar then press enter.
7. Once you permanently deleted the unnecessary files, reboot the device to return to explorer.exe to normal mode and remove the Y: drive letter.

Method 2: Windows 7 with MBR partition

Doing this method will make a permanent, but small increase in the free space of the device’s SRP.

1. Delete language folders

a. Open the Run window by pressing the Windows key + R. Type diskmgmt.msc then hit Enter. b. Select System Reserve partition then right-click on it.

c. Choose Change Drive Letter and Paths then select Add.

d. Type Y for the drive letter then click OK.

e. Click on the Start button and search for cmd. In the results, right-click on Command Prompt then choose Run as administrator. The command prompt window will appear.

f. Type Y: at the command prompt then press Enter.

g. Once you’ve switched to drive Y, type takeown /d y /r /f . then hit Enter.

NOTE: Ensure that the space and period after “f” is included in order for the command to work properly      

h. Type icacls Y:* /save %systemdrive%NTFSp.txt /c /t then hit Enter to back up the permission to the drive.

NOTE: Ensure that all files are marked as successful and that no files are marked as failed.

i. Type whoami then hit Enter. Record the username that appears. Afterwards, type icacls . /grant <username you got from whoami>:F /t then press Enter.

NOTE: Ensure that there’s no space between the username and “:F” or the command will not work.

j. In the File Explorer, open the SRP drive and select the Boot folder. Choose the             language folders you want to permanently delete. Language folders are named      with four letters split with a hyphen. For example: de-DE is the German language          while en-US is the U.S. English language.

2. Truncate the NTFS Log:

a. Open the Command Prompt then type chkdsk /L Y: to check the size of the NTFS Log. If the NTFS Log size is less than 5000KB, you need not truncate the file.

b. Type chkdsk /L:5000 /X /F then hit Enter to truncate the NTFS Log.

c. Return to Disk Management window. Select Action menu then select Check if the device’s SRP now has a larger amount of free space. Once there’s enough space, right click the System Reserve Partition then select Change Drive Letter and Paths. Choose Y: then select Remove.

3. If there’s still not enough available space after truncating the NTFS Log, resize the USN journal:

a. Open the command prompt then type fsutil usn queryjournal Y: to display the size in hex value. Convert the hex value to decimal then divide it by 1048576. The result you will get will be in MB. If the journal size is 30MB or more, proceed with truncating the file.

NOTE: To convert the Hex value to Decimal, open the Calculator app in Windows then choose View menu. Select Programmer then choose Hex. Type the Hex value then choose Dec.

b. Type fsutil usn deletejournal /D /N Y: then hit Enter to delete the journal. Type fsutil usn createjournal m=1500 a=1 Y: to recreate the journal having the new log size value.

4. Restore permissions

a. Type icacls Y: /restore %systemdrive%NTFSp.txt /c /t in the Command Prompt. Check if the files were successfully processed before proceeding. If you see a message saying some files failed while processing, this is normal since some of the files have already been deleted before performing a backup. However, if there are no successful files indicated, the command was not properly executed.

b. Type icacls . /grant system:f /t then hit Enter to adjust the ACL back to System. Now, you can set the owner of the drive by typing icacls Y: /setowner “SYSTEM” /t /c then press Enter.

c. Check if the device’s SRP now has enough free space by going back to Disk Management and refreshing the data. If the SRP already has sufficient space, you can now remove the drive letter. Right-click on the System Reserved Partition then choose Change Drive Letter and Paths. Select the Y: drive then choose Confirm deleting the drive letter by clicking OK.

Method 3: Windows 8/8.1 with MBR partition

This method makes a larger, but temporary, increase in the SRP free space.

1. Be sure you have an external drive having at least 250 MB free space and formatted as NFTS.

2. Open Run by pressing the Windows key + R. Type mscthen to choose the Recovery Partition. Right-click on it then choose Change Drive Letter and Paths.

3. Select Add then type Y for the drive letter, click

4. Click on the Start screen then type cmd in the search bar. In the results, right-click on Command Prompt then choose Run as administrator. The command prompt window will appear.

5. Switch to another drive by typing Y: in the command prompt. Once you’re in the drive Y, type takeown /d y /r /f .

NOTE: Ensure that space and period after “f” are included in order for the command to work properly.

6. Type whoami then hit Enter. Record the username that appears. Afterward, type icacls . /grant <username you got from whoami>:F /t then press Enter.

NOTE: Ensure that there’s no space between the username and “:F” or else the command will not work.

7. Once the command is completed, type attrib -s -r –h Y:RecoveryWindowsREwinre.wim then hit Enter.
8. Open File Explorer and check the drive letter of the external drive you’re using (In this case, let’s assume F: is the drive letter of the external drive so when you see F: for the rest of the steps, this means the drive letter of the external drive you’re using).
9. Type mkdir F:RecoveryWindowsRE in the Command Prompt then hit Enter. Afterward, type xcopy Y:RecoveryWindowsREwinre.wim F:RecoveryWindowsREwinre.wim /h
10. Type C:WindowsSystem32Reagentc /SetREImage /Path F:RecoveryWindowsRE /Target C:Windows to map the new path
11. Verify if the copy was successfully done then type del Y:RecoveryWindowsREwinre.wim /F
12. Return to Disk Management window. Click on the Action menu then hit Check if the device’s SRP now has a larger amount of available space. Once there’s enough space, you can proceed with the upgrade.
13. Upon completion of the upgrade, move back the wim file to the Recovery Partition. At this point, you can re-map now the location by:
    1. Open the Command Prompt then type xcopy F:RecoveryWindowsREwinre.wim Y:RecoveryWindowsREwinre.wim /h and press Enter.
    2. Type C:WindowsSystem32Reagentc /SetREImage /Path Y:RecoveryWindowsRE /Target C:Windows to re-map to the original path.
14. Return to the Disk Management window. Right-click on the Recovery Partition then choose Change Drive Letter and Paths. Select the Y: drive then choose Remove.

Error 2738 - What is it?

Error 2738 is associated with the VBScript engine. VBScript is the abbreviation for Visual Basic Scripting. It is an Active Scripting programming language developed by Microsoft and modeled on Visual Basic. It is used with a fast interpreter in a large variety of Microsoft environments. Error 2738 indicates that the VBScript engine is not registered properly on your PC. It occurs when you try to install or uninstall VBScript-supported applications on your system. The error message is displayed in the following format:

"Error 2738. Could not access VBScript run time for custom action."

Solution

Error Causes

There are several reasons for the error 2738 message pop up. These include: Incorrect or corrupt registry entries on your system. These entries interfere with VBScript support in Windows thereby generating such error codes.

• Removal of McAfee Antivirus
• Windows registry values are not updated accurately during the uninstallation of McAfee Software
• The Visual Basic Script is registered in the registry under the local user instead of the local machine

No matter what the cause of the error may be, it is recommended that you resolve the issue immediately without any delay.

Further Information and Manual Repair

Here are some of the easy and proven DIY methods to repair error 2738 on your PC:

Method 1

Hello everyone and welcome to our new Windows 10 tips and tricks article. Today we will be focusing on small Windows tricks that could prove very useful in everyday workflow and hopefully make your life easier by implementing them in your daily routine. I am very excited to share this with you all and I hope that you will use them from now on. That being said let us begin.

Tip 1: Minimize all open windows except one.

Daily to the daily routine can involve many opened windows on a desktop and sometimes things can get messy, if you want to minimize all windows to the taskbar except one do this: Click on one window thus selecting him, click and hold the left mouse button on that windows title bar, now shake it up and down and all other windows will escape down to taskbar leaving only one you are shaking on the desktop.

Tip 2: Open the Secret Windows menu.

Through our tutorials on various errors and fixes, we have used this method already but here it is again since it is worth mentioning. If you want to open the command prompt easy and fast, or device manager, event viewer, shut down, etc. In order to open this secret menu all you need to do is press ⊞ WINDOWS + X.

Tip 3: Create an Event without opening the calendar application.

You can easily create an event without opening a calendar application, all you have to do is left-click on the clock in the taskbar, click once on a date for the event, and under calendar in event field type event description. The event will show in the calendar application like it was entered there.

Tip 4: Taking a screenshot.

This one is my favorite and it speeds up workflow very very much. Typically you take screenshots by pressing the PrntScr button on your keyboard. Now, the problem with this approach is that the screen is placed in computer memory, in the clipboard and you will need another picture processing application in order to save it. Now if you would press ⊞ WINDOWS + PrntScr, the picture would be automatically saved in your pictures/screenshots folder. And if that is not enough, you can press ⊞ WINDOWS + S + SHIFT to start Snip & Sketch tool and select the area which you would like to screen capture, this method will also place pictures in the clipboard.

Tip 5: Open pinned applications in your taskbar with your keyboard.

We have covered this one in our Windows keyboard shortcuts tips and tricks here, but if you missed that article here is the tip again. By pressing ⊞ WINDOWS + number 1,2,3...0 you will start the application from your taskbar counted from left to right.

Tip 6: Check how much Hard drive space installed applications are taking.

Applications and temporary files grow over time and can slow the system and cause some other unpleasant experiences. Go to Settings > System > Storage, click on the Hard drive on which you have installed applications, and see how much each one is taking, you can remove it from this screen also freeing some space.

Tip 7: Remove ads from the START menu.

Windows has so-called suggestions in the START menu, no matter how Microsoft is calling them, let's face it, they are ads and in my opinion, they do not belong in my START menu. To turn them off, go to Settings > Personalization > Start. Toggle the setting called Show suggestions occasionally in Start to the off position.

Tip 8: Shut down background applications.

Some applications are running in the back and are taking system resources and can send telemetry information, if you want to turn them all off go to Settings > Privacy > Background apps. To stop all apps from running in the background, toggle Let apps run in the background to off. You can choose which apps to run in the background individually by going down the list on the same page.

Tip 9: Use Background scrolling.

Did you know that you can scroll on inactive windows? To do this, just hover over the inactive background window and roll your mouse when the content of the window should be scrolling even if it's not one you are working on. If by any chance this is not happening, go to Settings > Devices > Mouse, and toggle Scroll inactive windows when I hover over them to On.

Tip 10: Show file extensions in File Explorer.

By default extensions of files are hidden, so let's say that for example, you are in a folder with pictures, you have plenty of pictures there but you do not know are they JPG or JPEG for example, do not worry there is an easy fix to bring showing extensions back. Start File Explorer, click on view top menu item, click on options, Uncheck the box that says Hide extensions for known file types. Click Apply, and OK.

Tip 11: Use focus assist.

Set it up by going to Settings > System > Focus assist. Choose from three options: Off (get all notifications from your apps and contacts), Priority (see only selected notifications from a priority list that you customize, and send the rest to your action center), and Alarms only (hide all notifications, except for alarms). You can also choose to automatically turn this feature on during certain hours, or when you're playing a game.

Tip 12: Rotate your screen.

If you have multiple screens set up or you have the rotatable screen press and hold CTRL + ALT together, then use a directional arrow to flip the screen. The right and left arrows turn the screen 90 degrees, while the down arrow will flip it upside down. Use the up arrow to bring the screen back to its normal position.

Tip 13: Enable GOD mode.

Have you always felt limited with Windows settings? Don't be, Right-click on the desktop and select New > Folder. Re-name the new folder with this bit of code: GodMode.{ED7BA470-8E54-465E-825C-99712043E01C} To enter the "God Mode" window, double-click the folder.

Tip 14: Use Virtual Desktops.

Click on Task View (the icon next to the search box). This will separate all your open windows and apps into icons. You can then drag any of them over to where it says "New desktop," which creates a new virtual desktop. Once you click out of Task View, you can toggle between virtual desktops by pressing the ⊞ WINDOWS + CTRL + right/left arrows. To remove the virtual desktops, just go back into task view and delete the individual virtual desktops, this will not close out the apps contained within that desktop, but rather just send them to the next lower desktop.

Tip 15: Customize the command prompt.

Yes, you can customize the command prompt, in order to do so, open it and right-click on its title bar, choose properties and go wild. Special badge if you make it look like commodore 64 BASIC.

Tip 16: Dictate, not type.

If you have speech recognition ON, pressing ⊞ WINDOWS + H will bring up a voice recorder, just speak and see how you can easily "write" emails, etc.

Tip 17: Use sandbox.

In Windows you have a sandbox option, which will open another Windows instance inside Windows, what do you need this? Well once the sandbox is closed everything in it is closed and if you catch the virus or other dangerous software, closing the sandbox will destroy it not affecting your actual Windows. Use it for safety testing and enjoy an easy life. Enable Windows Sandbox inside the Control Panel.

Tip 18: Use a hidden game bar.

Press the ⊞ WINDOWS + G, you can pull up the new-and-improved Game Bar. This lets you switch your Windows PC into gaming mode, which pools system resources to the game, turns off notifications, and lets you record and broadcast your gaming, along with added panels for controlling your audio, monitoring FPS, and tracking achievements. And that's it, Our 18 tips and trick to make your Windows 10 life easier, more productive, and overall more enjoyable. I certainly hope you have enjoyed reading this article same as I was writing it. Until next time if I do not see you, good afternoon, good evening, and good night.

Error Code 0xC004C770 – What is it?

If the Error Code 0xC004C770 popped up on your computer during your activation of the Windows 10 software, don’t worry. This is a fairly common error, especially for people who own more than one computer upon which Windows 10 is installed and activated. The gist of this error code is that the product key that you have entered has already been claimed or used on a different computer. Because there are limitations on the number of computers that can use any given license activation code or product key, this error code can arise when you have exceeded that limit. If you have a single-use license and have already entered the particular product key onto another machine, you may see this error come up during activation.

Both Error Code 0xC004C770 and Error Code 0x803FA071 arise from the same problem and the same steps can be used to resolve both error codes.

Solution

Error Causes

Error Code 0xC004C770 is likely to appear on your screen during activation of Windows 10 if you or anyone else in your organization have already entered in the product key used on another computer. If you have a multiple-use license, the product key that you are entering may already have been used for the maximum number of computers allowed under that license.

Further Information and Manual Repair

There are two basic methods for addressing the issues associated with Error Code 0xC004C770. These methods can easily be implemented by anyone who is comfortable interacting with the Windows Store from their computer, which makes the resolution of this particular error code fairly simple and straightforward.

If you are unable to complete the steps below or Error Code 0xC004C770 has not been resolved after following the guides below, contact a Windows technician who is familiar with the Windows 10 activation process to assist you in the process. You can also get in touch with the Windows technical support team to assist you in the process if needed.

Method One: Purchase A New Product Key from Windows

If you have already used the product key on another computer or have used it on the maximum number of allowed devices, you may need to purchase an additional product key for the computer with Error Code 0xC004C770. Product keys can be purchased physically from a retailer that sells Windows 10 software licenses or purchased directly from the Windows store.

To purchase a new product key directly from the Windows Store, follow the steps below:

• Step One: Select the Windows start button at the bottom of your toolbar. Click on “Settings,” then select the option for “Update and Security.”
• Step Two: Click on the “Activation” option.
• Step Three: In the menu that appears, choose the option to “Go to Store” and follow any on-screen instructions to finalize a purchase of the Windows 10 software and product key.
• Step Four: Use the new product key to complete the installation and activation of the Windows 10 software on your computer.

If you are unable to see the “Go to Store” option when you reach the “Activation” page, you may not be set as an administrator of your machine. In this case, get in touch with the support personnel from your company to complete the purchase, installation, and activation process on your computer.

Method Two: Attempt to Finish Activation via Phone

For users who have changed out parts of their computer’s hardware, like putting in a new motherboard or activating a new hard drive, you may have more success if you attempt activation through a phone.

In order to activate your copy of Windows 10 from your phone, follow the steps below:

• Step One: On your mobile device, open up the search box from the taskbar.
• Step Two: In the search box, enter the phrase “SLUI 04.”
• Step Three: Select the “SLUI 04” option that appears.
• Step Four: Follow the directions given on the screen to complete the activation process for your copy of Windows 10.

As with any error code resolution, if the methods above are not successful or if you are not comfortable with your ability to successfully complete the steps above, get in contact with a qualified professional who is trained in the Windows 10 activation process to assist you or download a powerful automated tool to get the job done.
