Hello everyone and welcome to another great tutorial from errortools.com I hope everyone is feeling great and that you are prepared to boost the performance of your computer. This time we will speed up Windows startup time and overall performance by eliminating startup programs that we don't need and do not use.
Microsoft itself and some application developers tend to have some applications or some services always active and set to be loaded on Windows startup. If you want to change which of these applications are starting up with your Windows and change them, follow this easy guide and you will be speeding up your Windows in no time.
First thing is to open a task manager, fastest and most direct way of doing this is with a keyboard combination of CTRL + SHIFT + ESC
When Task Manager opens, click on the startup tab on top.
Once you click on startup you will get a list of applications that are set to be started when Windows is booted.
You can now click on the application and then click on disable on the bottom button, the application status will update in task manager to disabled and it will not be booted anymore when Windows starts. In this same manner, you can enable back some applications if you changed your mind about them.
Please note that some applications are using some services and must have them running or they will not work properly. The best practice is to disable applications you are positive you will not use or use rarely so you do not want them to slow down Windows.
Kindle is, without doubt, a great piece of hardware, perhaps it is the closest thing to a book within the domain of digital devices. With its low price and usability, it has found itself in many homes and within the grasp of many readers in the world. You can buy digital books in the Amazon store for fraction of a regular price if it digital Kindle edition. You keep your library in the cloud and download just books you want to read on your device.
In this article, we will explore how you can send your existing PDF or any other supported file that you already have to your kindle device so you can read it on it.
Before we begin, you should make sure the file you're trying to convert is compatible with the Kindle:
HTML
RTF
JPEG
GIF
PNG
BMP or
PDF
The compatible file types cover most formats you're likely using, but if you find the document you want on your Kindle isn't compatible, there are a few ways to convert it. In the program it typically opens into, like Microsoft Word for .doc files or an image editing apps for .PNG ones, select 'Save As', and in the drop-down menu, see if any of the compatible options are available.
If not, you could try a PDF converter tool. There are plenty of great paid options and a few good free ones too.
Transfering PDF
To get a PDF on a Kindle, you're going to need to know your Kindle's email address. You'll need to head over to the Amazon website and sign in first. Select 'Your devices and content', click 'Manage Devices'. You should see a list of the books you have assigned to your Kindle account, above this list, in a toolbar should be some options - you'll currently be on 'Content', which should be followed by 'Devices', 'Preferences' and 'Privacy Settings'. Click on 'Devices', and in the next menu, select the option for the Kindle you want the document on. You'll be brought to a Device Summary page which tells you your Kindle email as well as the type of device it is.
You now need to approve your personal email, so that when the Kindle receives your PDF, it knows to download this. Make sure the email you approve is the one you're planning to send documents to your Kindle from otherwise it won't work. To approve your email address follow the steps for finding your Kindle email address but instead of selecting 'Devices' in the top bar, click 'Preferences'.
Scroll down this list until you find Personal Document Settings, and select this option so it expands into more options. From here, scroll down until you find 'Approved Personal Document E-mail List'. This list will show people who can email stuff to your Kindle, Below the emails is an option to 'Add a new approved e-mail address', which you should select. Enter your email address and click 'Add address' to get yourself approved.
Head over to your email client of choice, attach the file to an email, and send the email to your Kindle email address. You're able to send multiple documents at once, so if you have loads of files you want on your Kindle, you don't need to send separate emails. If you're sending over a PDF file, you can ask Amazon to automatically convert the file into a Kindle one, which lets you annotate the sections and change the font size. Simply put the word 'convert' as the subject line and the rest will be handled for you. 'Sync Your Kindle'.
If you suddenly encounter an error message that says, “This webpage is not available, Err_Connection_Closed” while browsing the internet or visiting a website and the website fails to load, then it means that there is some problem with your network connection. Similarly, you may also get other error messages like “Err_Network_Changed”, “Err_Connection_Reset” and “Err_Internet_Disconnected” errors in different browsers like Chrome, Firefox, and Edge.
The problem lies in your Windows 10 computer and your internet connection since this is a network issue. So before you troubleshoot the problem using the suggestions given below, you need to refresh your browser first or you could also tap Ctrl + F5 on your keyboard to hard reload the webpage. If you’re still getting the same error message, then proceed to the guide below.
Option 1 – Try removing the Proxy
Removing the Proxy might also help you in fixing the “This webpage is not available, Err_Connection_Closed” error. 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.
Now click the OK and the Apply buttons.
Restart your PC.
Note: If you are using a third-party proxy service, you have to disable it.
Option 2 – Try using Google Public DNS
If the first option didn’t resolve the issue, you can try to use the Public DNS by Google and see if it can help fix the problem. You have to modify the DNS settings in your system explicitly and use the DNS IP addresses.
The first thing you have to do is right-click on the network icon in the Taskbar and select Network and Sharing Center.
Next, click on the “Change Adapter Settings” option.
After that, search for the network connection that you are using to connect to the internet. Note that the option might be “Wireless Connection” or “Local Area Connection”.
Right-click on your network connection and click on Properties.
Then select the new window to choose the “Internet Protocol 4 (TCP/IPv4)” option.
After that, click on the Properties button and click the checkbox in the new window for the option “Use the following DNS server addresses”.
Type in “8.8.8.8” and “8.8.4.4” and click OK and exit.
Option 3 – Reset Winsock, TCP/IP & Flush DNS
Resetting Winsock, TCP/IP, and flushing DNS might help you resolve the Err_Connection_Closed error. To do so, follow these steps:
Right-click on the Start button and click on Command Prompt (administrator) so you can pull up an elevated Command Prompt.
After that, execute each one of the commands listed below. And after you typed in one after the other, you have to hit Enter.
netsh winsock reset – type in this command to reset Winsock
netsh int ip reset resettcpip.txt – type in this command to reset TCP/IP
ipconfig /flushdns – type in this command to flush the DNS cache
Next, restart your PC and check if the problem’s fixed.
Option 4 – Disable both the Antivirus program and Firewall temporarily
There are times when antivirus programs and the firewall blocks a website that they consider to be malicious or even because of false-positive effects which is why you have to disable these programs temporarily as it might be the reason why you’re getting the “This webpage is not available, Err_Connection_Closed” error when trying to browse the internet.
Option 5 – Try to check the network cables and then restart your router
The most obvious thing you can do first is to try checking if the network cables connected to your computer or router are properly connected or not. If it turns out that some network cables are not connected properly, then it’s probably why you’re getting this error.
Option 6 –Try a Network Reset
When all else fails, you might have to consider resetting your entire network settings. Simply follow the steps below to do so.
Click on the Start button and then click on the gear-like icon for Settings to open it.
Next, select Network and Internet.
Then scroll down and look for “Network Reset” – click on it and then click on the Reset now button.

Windows 11 is a good-looking operating system but people love to make things personal and to their liking so we decided to help you in this mission with small customization of changing default system fonts inside Windows 11.
Since there is no really easy way to just switch the font windows is using for itself we will have to tweak a registry a little so before we start please do make a backup of the registry file and follow the steps as they are presented in order to avoid any errors and break the system.
So, if all precautions are made and you are ready to change your Windows appearance let's dive right into it:
Find and/or install the font that you wish to use
There are vast free font sites on the internet where you can find fonts that you like and wish to use but be very careful with your desired font selection. The font that you choose needs to be a complete typeface, meaning that it has to contain all glyphs, large and small font sizes, all special characters, etc or you will experience that in certain areas nothing will be displayed.
Once you have found the font that you like and made sure it is a complete font, install it on your system (you can skip this step if you just want to change the system font with one already installed on your system)
Create REG file
Open notepad or a similar plain text editor in order to create a file that will apply changes directly into the registry and create a new file. Inside the file paste this text:
All the way to the bottom where it says: "Segoe UI"="NEW-FONT", change NEW-FONT with the font name that you have chosen or installed in the previous step. For example: "Segoe UI"="Ubuntu".
Now go to File > Save As and name your file however you want but give it REG extension so it looks like: my_new_windows_font.REG
Apply changes
Now that you have your registry entry saved, locate it and double-click on it, at this stage Windows warning will probably pop up, you can just ignore it and click on YES since you wrote the file and know what it is. After registry entry is applied reboot your PC in order for changes to take effect.
Rolling back
If you want to change the font to another one, just repeat this procedure again. If you want to roll back to using the default Windows font, repeat the process but with this code instead of the one provided in the REG file:
There are times when the Windows Search doesn’t work and you wouldn’t have a clue as to why it happened since it does not give any error codes. In such cases, you have to check the error logs in the Event Viewer to find out more about the problem. From there, look for an error with the Event ID 3104 in the Windows error logs and if you see an error message that says, “Enumerating user sessions to generate filter pools failed”, read on as this post will guide you in fixing the problem. Apart from the error message, you might also see more information in the details section of the log that says, “(HRESULT: 0x80040210) (0x80040210)”.
This kind of error is most likely caused by something that prohibits the search function from initializing. A lot of users assumed that it could be due to Cortana but it’s actually not. While some users also reported that they encounter the issue after they restarted their computers. This error was also reported with the same event ID 3104 on the Windows Server. According to security researchers, this error could be caused by problems in the Registry entry of Windows search. It could also be due to an issue with the SYSTEM account where it hasn’t been added to the DCOM Security. It is also possible that the Windows Search function has not been initialized.
To fix this error, you can try to rebuild the Search Index manually or run the Search and Indexing troubleshooter. You can also check the startup type of the Windows Search service or try some registry tweak.
Option 1 – Try to rebuild the Search Index manually
The first thing you can do to fix the problem is to manually rebuild the Search Index. You can do that by going to Control Panel > Indexing Options and from there, click on Advanced. After that, go to the Index Settings tab and then click on Rebuild > OK. Once you’re done, check if it fixed the problem.
Option 2 – Try running the Search and Indexing troubleshooter
You could also run the Search and Indexing troubleshooter in Windows 10 as it checks whether the settings are in place and automatically corrects any issues with the Windows 10 search function. To run this troubleshooter, just click on the Start button and select Settings > Updates and Security > Troubleshoot. From there, select the Search and Indexing Troubleshooter. Once the troubleshooter is done, restart your computer and see if it fixed the error.
Option 3 – Try checking the startup type of the Windows Search Service
In this option, you have to check the startup type of the Windows Search service since the service won’t start. To do so, refer to these steps:
Tap the Win + R keys to open the Run utility and type “services.msc” in the field and then tap Enter to open the Services Manager.
Next, from the list of services, look for the Windows Search Service or WSearch. Once you find it, right-click on it and select Properties.
After that, change the Startup type to Automatic and click on the Start button if the service is in the Stop state.
Now click on the Apply and OK buttons to save the changes made and then restart your computer.
Option 4 – Try changing the Registry entry for Windows Search
Before you apply some registry tweak, you need to create a System Restore point first. Once you have that covered, follow these steps:
Tap the Win + R keys to open the Run utility and type “Regedit” in the field and tap Enter to open the Registry Editor.
If a User Account Control prompt appears, just click Yes to proceed.
After opening the Registry Editor, navigate to this registry path: HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows Search
From there, click on Windows Search and look for the key named “SetupCompletedSuccessfully” and change its value to “0”. Just right-click on it and select Modify.
Then input “0” as its value data and click on OK to save the changes made.
Exit the Registry Editor and restart your computer.
Now check if the Enumerating user sessions to generate filter pools failed is fixed or not.
Hive ransomware has been targeting Microsoft exchange servers lately vulnerable to ProxyShell security issues in order to deploy various backdoors. Once the backdoor has been placed various attacks can be performed including but not limited to network reconnaissance, stealing admin accounts, taking valuable data, and even installing and deploying file-encrypting algorithms.
ProxyShell wide abuse
ProxyShell is a set of three vulnerabilities in the Microsoft Exchange Server that allows remote code execution without authentication on vulnerable deployments. The flaw has been used in past by various ransomware like Conti, BlackByte, Babuk, Cuba, and LockFile.
Security vulnerabilities have been reported to be fully patched on May 2021 but how Hive was able to still be successful in exploiting PowerShell and infiltrating into the system there seems to be still some unpatched and open issues.
Hive
Hive has gone a long way since it was first observed in the wild back in June 2021, having a successful start that prompted the FBI to release a dedicated report on its tactics and indicators of compromise.
In October 2021, the Hive gang added Linux and FreeBSD variants, and in December it became one of the most active ransomware operations in attack frequency.
Last month, researchers at Sentinel Labs reported on a new payload-hiding obfuscation method employed by Hive, which indicates active development.
Distributed Component Object Model or DCOM is a module on Windows computers that allows computers to run programs over a network to another computer. It is a software component from Microsoft that allows COM objects to communicate with each other while that program is remotely running over the network. The COM Model is another extension of the DCOM model which both work together in order for the intended task to be executed. To make this module work, there are three components needed such as the Class Identifier or CLSID, the Programmatic Identifier or PROGID, and the Application Identifier or APPID.
However, DCOM does not always work as expected as it could still encounter some errors. One of them is error 1084. Because of this error, the execution of programs in a remote computer on the network would be interrupted. So if you encounter the DCOM error 1084 when you try to start a service like running the DISM tool or in other scenarios on your Windows 10 computer, then this post could help you. Refer to the instructions given below to start troubleshooting the problem.
Option 1 – Try checking the status of DCOMLAUNCH Service or DCOM Server Process Launcher and its 3 dependencies
The DCOM Server Process Launcher service launches both COM and DCOM servers in response to object activation requests. This is why if this service is stopped or disabled, the programs that are using COM and DCOM won’t properly function. So you need to make sure that the DCOMLAUNCH service is running.
In the Cortana search box, type “services” and click on the Services icon to open the Services Manager. Alternatively, you can also tap the Win + R keys to launch the Run prompt and then type “services.msc” in the field and hit Enter to open the Services Manager.
Next, check the following services:
DCOM Service Process Launcher
Background Tasks Infrastructure Service
Local Session Manager
Remote Procedure Call (RPC)
Then right-click on each one of the services and click on their Properties.
After that, select Automatic from the drop-down menu of Startup Type and make sure that all the aforementioned services are Running.
Now click OK for each one of the services.
Option 2 – Troubleshoot the problem in a Clean Boot State
There are instances that some conflicting programs installed in your computer might be the one that’s causing DCOM error 1084. To identify which program is causing the problem, you need to put your computer in a Clean Boot State. To do so, follow the steps below.
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.)
From there, start to isolate the problem by checking which one of the programs you installed recently is the root cause of the problem.
Option 3 – Try to use the DISM tool
You might want to repair potentially corrupted files in your system as having them could also trigger the DCOM error 1084. To repair these corrupted system files, you can run the DISM commands:
Tap the Win + X keys and click on the “Command Prompt (Admin)” option.
After that, input each one of the commands listed below sequentially to execute them:
Dism /Online /Cleanup-Image /CheckHealth
Dism /Online /Cleanup-Image /ScanHealth
Dism /Online /Cleanup-Image /RestoreHealth
Once you’ve executed the commands given above, restart your computer and check if the DCOM error is now fixed.
Option 4 – Reset your computer
Tap the Win key or click on the Start button located in the Taskbar.
Then click on the Power button at the bottom right portion of the screen.
Next, press and hold the Shift key on your keyboard and then click on Restart. This will restart your Pc into the Advanced Startup options.
Note: Once you have access to the Advanced Startup options, you have to go to the setting which allows you to Reset your Windows 10 PC. All you have to do is select Troubleshoot > Reset this PC to reach the following screen
Afterward, select either the “Keep my files” option and then proceed to the next on-screen instructions that follow to reset your Windows 10 computer without losing your files.
Hello everyone, last time we were talking about disk cleanup and its benefits, but as you need to keep your System clean you should also clean and keep your hardware clean as well. Many system issues could be traced and could happen due to dirty PC. In this article, we will give you tips on how to perform safely cleaning on your computer and hopefully point good sides to it so you can develop a healthy habit of regularly cleaning it and keeping it tidy.
Keeping your PC clean is not rocket science and you can do it with things you already and probably have in your house. One thing that I would recommend tho to purchase is antistatic gloves since they could prevent any kind of electrostatic discharges thus protecting your electric components.
If you have the option to disconnect your PC and get it outdoors, I would highly recommend this approach since all the dust will be dusted outside and not in the room where your computer is. If you can not it is still ok, but since some portion of dust will be set in the room, you might need to dust your room after cleaning your computer.
Cleaning outside case & redusting inside
The first thing after disconnecting your computer is to dust it from outside, here you will need a vacuum cleaner and a brush, gently brush outside dust from your casing and vacuum it with your vacuum cleaner. You can use dustcloth for larger parts but use the brush for fans and connectors.
After you have done cleaning the outside part, open the side of your computer casing, put on your antistatic gloves, and get a fine and soft brush, repeat dusting and vacuuming of the inner parts of your computer. If your computer is not regularly been cleaned this part will take a little longer since there would be excess dust inside and it will take a longer time to vacuum it all but keep going until you are left with no dirt.
Cleaning it inside
Fans are troublesome to clean since they will rotate when brushed and that could make you miss certain sports, in order to battle this get a tape and stick the fan into one position, brush areas that you can reach, then unstick it, rotate the head, stick it again in another position and dust off remaining areas which you could not reach before.
If your computer is very dirty and some hard dirt is at bottom of the connectors, disconnect desired component and clean the connection properly. plug it back in immediately after cleaning to avoid connecting it somewhere else.
Harder stains that could not be dusted could be cleaned with little alcohol. Get your dustcloth just a little wet with alcohol, just a corner, and gently wipe out sticky dust or spills if they are present. Leave it 10 minutes for alcohol to evaporate before plugging it back into an electric socket.
Thermal paste and cable management
If you have money and expertise, every 2 years would be a good idea to change the thermal paste on your processor, all you need to do is buy it from your local computer store online, remove the CPU fan clean the CPU and bottom of the fan and apply new thermal paste, place fan back and lock it. If you do not have expertise in this area, call someone who has to show you how it is done.
When cleaning it would be a good idea if you do not have any cable management to do it now, nice and tidy cables not only look good, they also improve your air circulation inside your casing making your computer cooling better.
once you are done with it, close back the casing side and plug it back in the wall.
Peripherals
When you are cleaning your computer, do yourself a favor and clean your keyboard, mouse, and screen as well. the keyboard can be quickly cleaned with compressed air in the can and screen and mouse with dustcloth.
That's it, remember, keep your PC clean and tidy and enjoy the benefits of non-hardware malfunctions caused by dirt and dust.
Roblox is a very popular online game with millions of gamers playing it each day and as such it will naturally bring a lot of malware and attack on players trying to steal and exploit them for monetary gains. The latest attack and high-profile stealing of currency and assets happened exactly in Roblox.
Malicious activities have been reported to come from chrome extensions. So far 2 extensions have been identified that have hidden malware inside them but there could be more of them currently undetected. Extensions work as a front while in the back they mine user logins and other data in order to steal stuff from the Roblox platform.
To make things worse some of the malware is within long extensions like SearchBlox. The SearchBlox extension allows you to search quickly for other users if it was legitimate but has been compromised within the last month. There is evidence that people are stealing Roblox currency with the data gathered by the hidden backdoor in it.
SearchBlox extension is still Active in Chrome Web Store, with the primary listing still with the "Featured " badge. Google is actively removing malicious software from its storefront on a regular basis but this one still lingers in it.
If you or your kid have this Chrome extension installed, uninstall it right away and always be careful about which extension you install and give access to your system, keep them updated and check various blogs and article sites to inform yourself when a bad one is found.
If you encounter an error saying, “Boot Device Not Found” when you turn on your Windows 10 computer, then you’ve come to the right place as this post will guide you on how you can fix this problem. Apart from the error message, you will also see a message that states, “Please install an operating system on your hard disk, Hard Disk<xxx>”. You will then be asked to tap the F2 key to initiate the System Diagnostics.
If you install the Windows operating system, it becomes the boot device, and when your computer boots, the UEFI or the BIOS looks for the operating installed on your drive and continues the process. So when you encounter the “Boot Device Not Found” error, this means that the UEFI or the BIOS wasn’t able to locate the drive where it can boot.
There are several suggestions you can check out to resolve this error. You can try checking the connection with your boot drive or change the boot order. You can also fix the Boot Record from Recovery and see if the primary partition is active or not. But before you troubleshoot the problem, make sure that you have a bootable Windows USB drive ready since two of the options provided below will require you to boot into the Advanced Recovery mode. Once you have this covered, proceed to each one of the following options.
Option 1 – Try checking the connection with the boot drive
If you have a custom computer that comes with a cabinet, you might want to open it and remove any connected power supply, and then check the wires. As you know, drives are connected with the motherboard using a cable. So all you have to do is check if both ends are connected properly and make sure that the connection is not loose. You could also try to unplug the cable and plug it back in.
Option 2 – Try changing the boot order
You might also want to try changing the boot order of your computer. Each time a computer boots, the BIOS or the UEFI follows a boot order. It is the one that tells where to first look for the boot drive and if for some reason, a USB is connected to your computer and the first boot device found in the USB, then you have resolved the problem. All you have to do is to remove the USB device and boot or go into the BIOS and change the boot order yourself.
Option 3 – Try to rebuild the BCD files
The next thing you can do to resolve the issue is to Rebuild Boot Configuration Data or BCD files.
You can start by booting into the installation environment for Windows 10 from an installation media.
After that, click on Repair your computer and on the blue screen, select Troubleshoot and then select the Advanced options menu.
From there, select Command Prompt and once you open it, enter each one of the commands given below by sequence.
bootrec /FixMbr
bootrec /FixBoot
bootrec /ScanOS
bootrec /RebuildBcd
Once you’re done executing the commands given above, type “exit” to close the Command Prompt window and then restart your computer and see if it fixed the “Boot Device Not Found” error.
Option 4 – Try setting the System Partition to Active
Like the first given option, you also have to make sure that you have a bootable Windows 10 USB drive before you proceed to set the System Partition to Active. Once you have it covered, refer to these steps:
Boot your computer using the bootable Windows 10 USB drive.
Next, click Next when you get to the Welcome Screen.
Then click on Repair your computer located at the bottom left part of the window and select Troubleshoot > Advanced Options > Command Prompt.
After opening Command Prompt, type the following command and hit Enter to start the Diskpart utility. It is a command line-based utility just like Command Prompt but has a UAC prompt once you provoke it. So if you encounter a UAC prompt, just click on Yes to proceed.
diskpart
Now type the following command:
list disk
From there, select your primary disk by typing the following command:
select disk number
After that, list all the partitions on the selected disk by entering the following command:
list partition
The command you just entered will list all the partitions created on your PC including both types of partitions that are visible to a normal user in the File Explorer as well as the ones created by Windows 10 by default which helps it in storing the boot files and other important system files.
Now type the following command to select the partition that is usually around 100 MB in size:
select partition number
Finally, type the following command to mark the partition active:
active
Then type the “exit” command to exit the disk part utility.
Once it’s done, the primary drive should now be active and you should now be able to boot into your computer without the “Boot Device Not Found” error.
When Task Manager opens, click on the startup tab on top.
Once you click on startup you will get a list of applications that are set to be started when Windows is booted.
You can now click on the application and then click on disable on the bottom button, the application status will update in task manager to disabled and it will not be booted anymore when Windows starts. In this same manner, you can enable back some applications if you changed your mind about them.
Keeping your PC clean is not rocket science and you can do it with things you already and probably have in your house. One thing that I would recommend tho to purchase is antistatic gloves since they could prevent any kind of electrostatic discharges thus protecting your electric components.
If you have the option to disconnect your PC and get it outdoors, I would highly recommend this approach since all the dust will be dusted outside and not in the room where your computer is. If you can not it is still ok, but since some portion of dust will be set in the room, you might need to dust your room after cleaning your computer.
