Started as an internal network and has slowly expanded since 1960 internet has taken over the world. In the beginning, it was a means of information change but in the modern age you can run applications and virtual machines over the internet, you can stream video and audio, and you can communicate in real-time with someone on the other side of Earth.
With the internet growing so fast in such a small amount of time it is only logical and wise to take a step back and take a good look at what it offers now, what are great things about it and what are some of the worst.
Good sides of the internet
Information
There are a lot of advantages of the internet, first and foremost is information. Internet was made as an information exchange service and even today you can find a lot of various information about various topics that interest you. A site like Wikipedia is a completely free online encyclopedia and a lot of news companies have their own internet sites where you can find free information and news.
On the other hand, there are also websites like udemy, edx, Coursera, and many others that will offer you the education, some for free, some for money but you can get a glimpse and part of university quality education for just a fraction of price.
Online shopping
Sites like Amazon have used the internet and launched themselves as today's multi-billion companies. In today's world, there is not a single thing you can not buy online. Many sites today are going from the large online marketplace where you can find everything to small niche specialized ones. Also every major brand in the world today has its own online store.
Other shops will offer you music, movies, games, etc. Services like steam, xbox pass, sony pass etc, will let you buy games online, other music, movies, and many more.
Streaming services
Days, when you had to buy movies in order to watch them at home, are gone, thanks to the internet we have plenty of streaming services for movies and tv shows as well as ones for music. If you do not want to spend money on actually purchasing things then a good idea is to have a streaming plan set up when you want it.
Email and messaging
Communication is a great thing and since the dawn of mankind people have been talking and sharing with each other, the internet has made it possible to send mail electronically and instantly and modern chat communication is everywhere. We can not just talk with our friends and family that can be on the other side of the world, we can also talk in real-time with the sales representative, with technical service, or attend online classes with a group of people.
Cloud storage services
Saving your pictures in this digital media age on the hard drive can be risky but thanks to modern technologies you can save most of your precious files on cloud servers for safekeeping. From pictures to documents and even other files that you need and want to save. There are some of them that will offer you a free amount and some basic free plans as well.
Bad sides of the internet
Malware, viruses, and phishing
We could not talk about the bad side of the internet if we do not mention its greatest threat. Bad sites, infected software, phishing emails, and many more malicious threats. Problem is that these kinds of tricks and attacks have become more and more sophisticated and harder to detect and avoid.
Pornography
Pornography is bad, having it freely available to children is even worse. Sadly the only way to regulate this is on a computer-by-computer basis by turning on parent control on each one. There are many studies that go into detail about why this is bad, sadly currently there are no effective ways to isolate this content.
No privacy
When we say there is no privacy we do not mean by using social media and not setting your privacy settings altho that also fits in this point, what we are talking about is data mining of your habits and things you do. It is well known that today lot of websites are using some form of AI recommender system in order to tailor your internet experience to suit your needs better. Most of these AI systems are trained by mining your data and analyzing your habits.
If you have 2 google accounts there is a high probability chance that for the same query you will get different results, depending on your so far browsing habits. The same goes for other services as well.
Dark webshops
There are some great things in dark and deep WEB-like sites with true news and information. Even some legit libraries where you can find and download rare books. Sadly as goes with the internet dark and deep WEB also has its well, dark sides, from disturbing content to shops that sell stolen items to straight stealing your money by parading as legit shops but only to steal your money.
Dating sites
We all try to find someone that is perfectly matched with us but using the online dating site has many proven bad effects on psychology. It also devaluates interaction between people and can lower self-esteem.
Bad habits
Since the internet has become wildly available and popular on various devices like tablets and mobile phones more and more people are spending an unhealthy amount of time on it. Harvesting the benefits of the internet is great but find some time for other people as well.
OEM Partition, also known as System Reserved Partition, is placed by the OEM to help users recover their computers or bring back the original state of the computer when it was bought. If you’ve observed that a part of your hard drive says “Healthy (OEM partition)” in the Disk Management and it occupies space in GBs, then this means that it’s normal and there’s nothing to worry about except that part of the storage space is not available and even when you right-click on it, the only thing it displays is the Help menu. Thus, in this guide, you will be guided on how you can merge as well as delete an OEM partition in your Windows 10 computer.
Since the Disk Management tool in Windows won’t let you merge or delete the OEM partition, you can just use the built-in command-line tool known as Diskpart. Note that you have to be extra careful when you run the commands as it could mess your computer up and before you proceed with the instructions provided below, make sure that you create a System Restore point first. Once you have that covered, follow the instructions below.
Step 1: Tap the Win + R keys to open the Run dialog box and type “cmd” in the field and tap Enter to open the Command Prompt.
Step 2: Next, execute this command to launch the Diskpart tool: diskpartStep 3: Execute this second command to view the list of the disks in your computer: list diskStep 4: Now select the disk you want to manage by executing this command: select disk xNote: In the command above, replace “x” with the letter of your disk.
Step 5: After that, execute this command to display all the volumes or partitions: list partitionStep 6: Now execute this command to select the partition you want to delete: select partition xNote: You have to replace “x” with the partition you want to delete.
Step 7: Once done, execute this command to delete the selected partition: delete partition overrideStep 8: Afterwards, execute this command to merge the OEM partition with the adjoining value: ExtendNote: if you only want to merge part of the partition, you need to use this command “extend [size=<size>]”. For instance, you want to extend its size by 5GB, then you need to type “Extend size=5000”. The size you set is the size you select from the OEM partition. This will extend the selected volume by size in MB or megabytes.

As you know, Diskpart is a useful utility that helps in managing the disks in a computer. It is a very useful tool that even when the GUI-based disk management tools in Windows 10 operating system fails, the Diskpart utility still tends to work. However, it also does not mean that this utility does not experience issues as it still does, from time to time. One of the issues you may encounter when using the Diskpart utility is when you encounter an error message that says, “DiskPart has encountered an error, Access is denied”.
This kind of error in the Diskpart utility could be caused by a number of factors. For one, it could be that the Write-Protection is enabled on the drive where the operating is being performed or it could also be that the Command Prompt terminal does not have administrator-level permissions to carry out the command. Thus, you can try to run the Diskpart utility again but this time with admin privileges or you could also remote the Write-Protection from the concerned drive. For more details, refer to the instructions given below.
Option 1 – Try running Command Prompt with Administrator-level permissions
In the Start Search, type “command prompt” and from the search results that appear, look for Command Prompt.
Once you found it, right-click on it and select the “Run as administrator” option.
After that, try to execute the Diskpart operation once again and see if you still encounter the same error.
Option 2 – Try to remove the Write Protection from the drive
As mentioned, removing the Write-Protection on the concerned drive could also help you fix the problem and there are two ways to get rid of the write protection – you can either use the Diskpart utility or the Registry Editor. How? Refer to the following steps.
Via Diskpart utility:
Open Command Prompt with admin privileges and then type the “diskpart” command and tap Enter to execute it.
Next, type “list disk” and tap Enter to get the list of all the Disk connects or all the partitions that are formed on those disks.
After that, you need to choose one command depending on the list of commands you entered. Type “select disk #” and tap Enter to select the disk or partition you want to select.
Then type “attribute disk clear readonly” and tap Enter to Disable the Write Protection on the selected disk or partition.
Via Registry Editor:
Tap the Win + R keys to open the Run utility and type “Regedit” in the field and then tap Enter to open the Registry Editor.
If you encounter a Blue Screen error that points to the Wdf01000.sys file, then this post might be of help. Wdf01000.sys is a file related to the Windows Driver Framework which is the one that manages the system drivers. So if this file ends up being corrupted, the drivers would start to cause trouble in the system which would lead to a Blue Screen of Death error eventually. There are lots of error descriptions that are associated with the Wdf01000.sys file such as:
DRIVER_IRQL_NOT_LESS_OR_EQUAL
System_Thread_Exception_Not_Handled
Page_Fault_In_Nonpaged_Area
System_Service_Exception
Kmode_Exception_Not_Handled
DRIVER_VERIFIER_DETECTED_VIOLATION
Although the troubleshooting steps you must take depends on the kind of BSOD error you are getting, there are a couple of options you can try to resolve the Blue Screen errors related to the Wdf01000.sys file. Refer to the options given below.
Option 1 – Try running the DISM tool
You can try running the Deployment Imaging and Servicing Management or DISM tool to fix the Wdf01000.sys Blue Screen error. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth”.
Open the Command Prompt with admin privileges.
Then type in the following commands and make sure to hit Enter right after you type each one of them:
Dism /Online /Cleanup-Image /CheckHealth
Dism /Online /Cleanup-Image /ScanHealth
exe /Online /Cleanup-image /Restorehealth
Do not close the window if the process takes a while as it will probably take a few minutes to finish.
Option 2 – Try to update or rollback your device drivers
If the first option didn’t work for you, then it’s time to either update or roll back the device drivers. It is most likely that after you updated your Windows computer that your driver also needs a refresh. On the other hand, if you have just updated your device drivers then you need to roll back the drivers to their previous versions. Whichever applies to you, refer to the steps below.
Open the Devices Manager from the Win X Menu.
Then locate the device drivers and right-click on them to open the Properties.
After that, switch to the Driver tab and click on the Uninstall Device button.
Follow the screen option to completely uninstall it.
Finally, restart your computer. It will just reinstall the device drivers automatically.
Note: You can install a dedicated driver on your computer in case you have it or you could also look for it directly from the website of the manufacturer.
Option 3 – Use the Driver Verifier Manager
The Driver Verifier Manager is another tool in Windows that could help you fix driver-related issues. And so if you want to fix the Wdf01000.sys Blue Screen error, you need to use the Driver Verifier Manager:
Type in the keyword “Verifier” in the Cortana search box to search for Verifier in Windows 10.
After that, select the option “Create custom settings”.
Make sure that you have checked everything except the options “DDI compliance checking” and “Randomized low resources simulation”.
Next, select the option “Select driver names from a list” option.
Afterward, you have to select all the drivers from any unofficial or third-party provider. To simply put it, you have to select all the drivers that are not supplied by Microsoft.
Then click on the Finish button.
Open Command Prompt as administrator and execute this command – verifier /querysettings
The command you just executed will display the Driver Verifier settings so if you see any of the flags enabled boot your Windows 10 PC into Safe Mode.
Open the Command Prompt as admin again and run this command – verifier /reset
The command will reset the Driver Verifier. Once the process is done, restart your PC and check.
Option 4 – Run the System File Checker Scan
System File Checker or SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files to good system files. To run the SFC command, follow the steps given below.
Tap Win + R to launch Run.
Type in cmd in the field and tap Enter.
After opening Command Prompt, type in sfc /scannow
The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:
Windows Resource Protection did not find any integrity violations.
Windows Resource Protection found corrupt files and successfully repaired them.
Windows Resource Protection found corrupt files but was unable to fix some of them.

If the display of your Windows 10 computer turns on all of a sudden no matter how put it to sleep over and over again, it always wakes up, read on as this post will guide you in resolving this peculiar issue.
In case you don’t know, the Windows 10 computer Sleep state is made in such a way that if it’s really important, it wakes up. You may have configured this kind of behavior or there could be some hardware component that’s interrupting its Sleep state. Thus, this post will give you some troubleshooting tips to fix the Sleep state issue caused by the Legacy Kernel Caller. The Legacy Kernel Caller points to the external hardware that’s causing your Windows 10 to wake up even when it’s in a Sleep state.
Step 1: Find out what’s keeping your computer from going to sleep.
To figure out what really is keeping your computer from going to sleep, you can execute the “powercfg –requests” command instead of checking the power configuration of your computer. This command will look for requests from applications and drivers that prevent the computer from turning off the display or from going to sleep.
To execute the command, simply open Command Prompt and type “powercfg –requests” and hit Enter. After that, you will see part of the result that looks like this:
“SYSTEM[DRIVER] USB AUDIO DEVICEAn audio stream is currently in use[DRIVER] Legacy Kernel Caller.”
Step 2: The next thing you have to do is remove all the external hardware connected to your computer.
In this step, you have to disconnect external hardware from your computer. Based on reports from users who experienced the same issue, the “TV card” is the culprit so make sure you remove that one. Once you’ve removed it, open Command Prompt and run the “powercfg –requests” command again and you’ll see that the “Legacy Kernel Caller” will no longer be on the list. In addition, your computer will get into its regular sleep mode once the hardware is removed. Once you do that, the driver gets hung and won’t release the power request despite being used.
Step 3: Try using the request override option
The powercfg command also offers a request override option which allows users to disable the requests from applications and services to wake the computer from sleep mode. To run this command, simply open Command Prompt with admin privileges. After you open Command Prompt, type the following command and hit Enter to disable requests from applications and services that causes the computer to wake from sleep state.
Powercfg -requestsoverride Driver "Legacy Kernel Caller" System
Step 4: Check the streaming and media applications
You also have to check if your computer is running an audio or video service in the background. In such cases, your computer won’t be able to go to sleep mode if these services are running in the background. You might have noticed that when you play a video or audio, your computer never goes to sleep. And if you have put it to sleep in between watching the video, then it’s probably why your computer is waking up. Thus, you have to stop these services.
Step 5: Check the devices that can wake your computer
If you didn’t see the Legacy Kernel Caller in the result after you execute the ”powercfg –requests” command, then you can try to execute the following command instead.
powercfg –devicequery wake_armed
After you enter this command, it will give you a list of all the devices that can wake your computer. So if there is anything other than the mouse, keyboard, touchpad, you have to check the power configuration of that device. To do that, go to the Device Manager and disable the device’s “Allow this device to wake the computer” option in its Properties
Step 6: Check the Sleep Advanced Settings
Click on the Windows key and type “control panel” in the field and select the related search result.
Next, select the Security and Maintenance option and click on the Power Options.
After that, you have to select the Change Plan Settings but keep in mind that this option is barely readable so you need to read each option carefully.
Now click on the Change advanced power settings button and a new window will appear.
Then look for the “Sleep” option and expand it. Make sure that the “Allow hybrid sleep” option is on.
Reboot your computer and check if your computer now functions properly. If it still didn’t work, you may have to reverse the changes you’ve made.
On the other hand, you could also run the Power Troubleshooter to resolve the Sleep state issue. This built-in troubleshooter will automatically fix any power-related issues in your computer.
DLL files, also known as Dynamic Link Libraries are external parts of applications that run on Windows as well as other operating systems. Almost all applications are not complete in themselves and store code in different files. In this post, we will be discussing one DLL file called ntdll.dll. It is described as “NT Layer DLL” which means that it contains some Kernel functions that help in the normal functioning of the Windows operating system. It is created by Windows in the System32 folder when the OS gets installed. This file can serve different programs simultaneously by providing them with different Kernel functions which support the programs’ performance. However, if you encounter the ntdll.dll file error on your Windows 10 computer, read on as this post will guide you in fixing the problem.

Open Command Prompt as admin from the WinX menu.
Next, type the following commands in the elevated Command Prompt and hit Enter to execute the command. This will re-register the affected DLL file using the Windows operating system tool, regsvr32.exe.
exe /u ntdll.dll
exe ntdll.dll
You should see a message saying, “DllRegisterServer in vbscript.dll succeeded” if the Regsvr32 tool was able to run successfully. After that, try to install the program again and see if it now works.
Option 2 – Disable problematic Internet Explorer add-ons
