Troubleshoot Error 651 on Your PC

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: diskpart Step 3: Execute this second command to view the list of the disks in your computer: list disk Step 4: Now select the disk you want to manage by executing this command: select disk x Note: 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 partition Step 6: Now execute this command to select the partition you want to delete: select partition x Note: 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 override Step 8: Afterwards, execute this command to merge the OEM partition with the adjoining value: Extend Note: 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.

Computer viruses are malicious applications that have the ability to self replicate and spread over the system and various devices, just like viruses in organisms. We all know that computer viruses are bad and that you should avoid them however you can. So in this spirit, we are taking a deeper dive into what kind of viruses exist and how they function.

1. File-infecting Virus

A virus that attached itself to an executable program. It is also called a parasitic virus which typically infects files with .exe or .com extensions. Some file infectors can overwrite host files and others can damage your hard drive’s formatting.

2. Macro Virus

This type of virus is commonly found in programs such as Microsoft Word or Excel. These viruses are usually stored as part of a document and can spread when the files are transmitted to other computers, often through email attachments.

3. Browser Hijacker

This virus targets and alters your browser setting. It is often called a browser redirect virus because it redirects your browser to other malicious websites that you don’t have any intention of visiting. This virus can pose other threats such as changing the default home page of your browser.

4. Web Scripting Virus

A very sneaky virus that targets popular websites. What this virus does is overwrite code on a website and insert links that can install malicious software on your device. Web scripting viruses can steal your cookies and use the information to post on your behalf on the infected website.

5. Boot Sector Virus

These viruses are once common back when computers are booted from floppy disks. Today, these viruses are found distributed in forms of physical media such as external hard drives or USB. If the computer is infected with a boot sector virus, it automatically loads into the memory enabling control of your computer.

6. Polymorphic Virus

This virus has the capability to evade anti-virus programs since it can change codes every time an infected file is performed.

7. Resident Virus

A resident virus stores itself on your computer’s memory which allows it to infect files on your computer. This virus can interfere with your operating system leading to file and program corruption.

8. Multipartite Virus

A type of virus that is very infectious and can easily spread on your computer system. It can infect multiple parts of a system including memory, files, and boot sector which makes it difficult to contain.

Despite popular belief, there are a lot of users running Linux OS. Linux offers great security and working environment and 96.3% of the world's top 1 million servers run on Linux. 90% of all cloud infrastructure operates on Linux and practically all the best cloud hosts use it. But gaming on Linux is limited, enter Steam proton a Valve’s gaming solution.

What is Steam proton?

Proton is a WINE fork with some extra capabilities, to play games and run applications not native and not made to run natively under Linux OS. It is supposed to bridge the Gaming issues for PC users and let them more freedom in choosing an operating system to game on.

Find out if your game supports Proton

Although there are a lot of titles that nowadays run natively on Linux some will still need proton in order to run at all and sadly some of them will not be able to run on Linux even via proton but seeing how Valve is busy and it is trying to push its ideas and technology slowly this gap is closing. In order to see how the game you want to play performs and behaves on Linux and proton environment visit https://www.protondb.com/ and find out. As soon as the site loads you will be greeted with statistics and a search option to find out the status of the desired game with one of the given statuses: Borked, Bronze, Silver, Gold, Platinum, and Native. As you probably guessed native means that the game will work on Linux out of the box and borked will probably not work at all. Platinum and gold status means that game will run on proton without any input or tweaks from the user while silver and bronze means that it will work but might need some tweaks in order to make it work.

How to get Steam proton?

In order to run games under proton inside Linux, you will need firstly a Steam client which luckily works naturally on Linux. Unlocking/activating Steam Proton on your Linux-based system is easy. Just head over to Steam > Settings > Steam Play and toggle the option “Enable Steam Play for Supported Titles”. Valve has tested and fixed some Steam titles and you will now be able to play those titles. However, if you wish to go even further beyond, and play titles that even Valve has not tested, toggle the option “Enable Steam Play for all titles”.

Conclusion

Even we are not there yet, native gaming on Linux is gaining a foothold each day. Will Steam’s OS with proton technology be one that will turn the tide from Windows or some other tech we cannot tell but one thing is for sure, more choices mean better products so I am hopeful for a bright future.

Building your own custom PC system can be one of the greatest things you can do to your budget. Instead of going for a rebuild, we will go into detail about why building your own PC is a much better option. Also, note that if you do not possess enough technical knowledge about a topic there are plenty of stores that will offer you advice on components and after all, you can always get help from a friend.

So without further diversion from the topic, let us explore all the benefits of building a custom computer.

Building a custom PC is cheaper

At the first look, this statement does not feel right since when you look at the prebuilt systems you get a feeling that it is much cheaper than do it yourself variant and although CPU and GPU seem like a great deal I beg you to look under the hood on other components. Usually to lower price compromise would be made on other crucial components like SD or power supply, a PC case, or motherboard so even if you have a good CPU and GPU that will not matter much since other components would not be able to catch up with them. After all, prebuild computers will need to pay people who are building them and there is no way that will be cheaper if you just plain went and bought the same components yourself and install them.

When you are in control in choosing each component there is not only being cheaper online, it is flexibility with building itself. You choose which components you want to be stronger and which to be normal. Also, you can choose the exact model of the given component leaving you more in control and open to future upgrades.

More flexibility

Also, it may sound irrelevant but when building your own custom PC you can also choose which company you would like to purchase for each model, yes considering the CPU it is AMD or Intel but when you are buying a case, SSD, GPU, and other components choosing the right company for your needs is also the thing that should not be overlooked.

You can customize it the way you want

Not really a quality argument but with a custom PC build, you can choose would you like that RGB component or not, you choose do you like white or black fans, and many more things. You really can place a personal stamp on the computer making it indeed a personal computer.

You choose OS and applications

When you buy an already prebuilt PC, usually it comes with some sort of OS on it, sometimes it is freedos, Linux and sometimes it is Windows Home. When you get your hands dirty you can place whichever system you want on it and install applications that you use and know and some preinstalled typical apps.

After determining the cause then you can now start fixing the error. Check if Hardware is functioning properly. If the cause is due to a hardware malfunction, you will have to make sure that all the pieces you are using are working. All the wires should be attached to their respective ports. Not only that, but you also must make sure that before installing the hardware, it is compatible with the Windows version that is installed into your computer. Use Compatible software. If the problem was caused by software or a driver, you can uninstall and reinstall it. Always make it a rule that whenever you install a program or new software to your computer, make sure it is compatible with your operating system and never skip a step during the installation process. You also have to see to it that the program you are installing does not contain any viruses, malware, or spyware that can be harmful to your computer. Update your Drivers Regularly. In most cases though, the cause of the APC_INDEX_MISMATCH error are outdated device drivers. To resolve this, you will have to go to your Control Panel then look for Device Manager. As soon as you are in the Device Manager window, you can now see the different devices running on your computer. You right-click on each device and check the Properties.  In the Properties window, click on the Driver Tab and look for the date when it was last updated. You can then go to the manufacturer’s website and compare the dates. For a new Windows operating system, you no longer have to go to the manufacturer's website though. All you have to do is click on Update Driver and it will automatically search for updates online. Use a Genuine Operating System. There are also cases where the 0x0000001 error won’t allow you to access your computer. In this case, we have to suspect that the problem could be in your Operating system.

If you recently upgraded your computer or if you’ve just switched to a new Windows 10 PC, the most common errors you might encounter are the Windows Activation errors. This issue boils down to the Windows Activation server which has either failed to validate or recognize the license tied to the digital account. In this post, you will be guided on how to fix an activation error in an organization with an error code 0x8007007B. It contains this exact error message: “We can’t activate Windows on this device as we can’t connect to your organization’s activation server. Make sure that you’re connected to your organization’s network and try again. If you continue having problems with activation, contact your organization’s support person. Error code 0x8007007B.” Various computers are activated via the KMS licensing (Key Management Server) in organizations. Computers that are activated using this process do not get a permanent activation and have to stay connected to the organization instead of for at least 7 months or 180 days. It is common in Pro and Enterprise versions that are deployed in bulk for at least hundreds or thousands of computers. So imagine a user with a personal computer in the office who decided to leave the organization but will still have an activated Windows key. And so to prevent that from happening, organizations use the KMS licensing. Another possible cause of the error is in case some user used an organization key and later on, the PC just got upgraded or downgraded to a version that is not compatible with that copy of Windows. To fix this Windows Activation error, here are some suggestions that might help.

Option 1 – You can try connecting to the organization’s network and activate the computer. But before that, you need to first check if the computer actually belongs to an organization or not.

• Tap the Win + R keys to open the Run dialog box.
• Type “cmd” and hit Enter to open an elevated Command Prompt.
• After that type the vbs /dlv command and hit Enter to execute it.
• Next, check if the Product Key Channel says “GVLK”. If it does, then it means that your computer was activated using volume licensing.

Option 2 – Change Licence Key

If you’ve recently left an organization then it’s best if you buy another copy of Windows 10 and then change the license key. This time, make sure that the license key is for the same version of Windows. However, if it’s different, you need to format your computer.

Option 3 – You can try activating Windows 10 using a 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.

Option 4 – If you think that the issue is caused by some hardware changes, you can try using the Activation Troubleshooter.

There are times when users already have the license keys and were able to activate Windows. However, it doesn’t last long and only works for a while and it’s suddenly throwing up an activation error like this one. To use the Windows Activation Troubleshooter, just go to Settings and to Activation and then run the troubleshooter from there. If you've made some modifications to your hardware, you have to click the “I changed hardware on this device recently” option for further suggestions.

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.
