How to Fix: Not a Valid Win32 Application Error

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.

Disk partitioning is a concept that’s been around for so long, but is still only familiar to few. If done right, it can help get your computer in perfect order. 

Today we bring you a simple definition of disk partitioning, its pros and cons, and a quick tip on how to do it properly to reap its full benefit!

Definition and purpose

The simplest way to define disk partitioning would be: it’s exactly what it sounds like. It means taking a hard disk drive and separating it into different segments. These segments are called partitions. You can visualize it as cutting a cake into smaller pieces - not necessarily of the same size, though. 

So what is the purpose of these pieces?

Well, when you first get a hard drive, it’s basically just a bunch of unallocated storage space. Until there’s at least one partition, this space is unusable to your operating system. Once you create a partition, your OS will recognize it as usable storage space. 

You can choose to create a single partition and use it for all your files, from program files to personal data. A lot of off-the-shelf computers come with one primary partition like this and a small secondary one reserved for recovery purposes. 

Whether or not you want to split your disk into more than one segment is up to you. We would generally recommend it, though. The whole point of partitioning is for each segment to have its own purpose.

So treating all your storage space as a single unit containing different file types would be like constructing an office building with only one massive room for everything - day-to-day work, conferences, interviews, etc. And all of this for different departments of the company. You can see how this might get a little messy.

Creating multiple partitions eliminates the task of running several different types of files from the same place. This takes a heavy load off the entire process of accessing data.

Disk partitioning also brings a ton of other benefits to the table. An important disclaimer, though: there are disadvantages too. We will walk you through both sides to help you get an objective idea and make an informed decision.

What are the benefits of disk partitioning?

1. Better file organization

This is the most obvious and perhaps the biggest advantage of partitioning your hard drive. 

As we already mentioned, partitioning allows you to create separate segments for different file and data types. You wouldn’t want to use the same partition for your system files and for games, would you? 

If organization and time management are important to you, then multiple partitions are the right solution. Searching for specific files will be much easier overall. Say you have one hard drive, but three partitions: C for the system files alone, D for multimedia files and documents, and E for games and apps. Your computer loads the system from C without interference from the other two, and you know exactly where to look when searching for a file.

2. Easy reinstallation

File management isn’t the only thing made faster and simpler thanks to partitioning. If you opt for creating multiple segments on your drive, reinstalling Windows will be easy peasy. 

That’s because all you need to do is format the partition your system is on. Then you reinstall the OS on it, and there you go. Now you have a clean installation, with all your files saved on other partitions intact. You can even make a copy of your system partition, so you can revisit the exact same installation in the future if you want. And the whole time your pictures, music, documents stay exactly where you left them. 

3. Possibility of using multiple file systems

By now you’ve understood that partitions function completely separately. This means that, if for some reason you need multiple file system capabilities, partitioning will allow that.

One segment could be used for, say, an NTFS file system, while another could run ext or APFS.

4. Running different OSes

You’re an avid Windows user but need to use Linux on the side? No problem. You don’t need to buy a separate computer or anything. The possibility of running different file systems also means you can use partitioning to run multiple operating systems.

Doesn’t that sound enticing? One machine for multiple totally different uses!

5. Backup and recovery made simple

Data loss can happen on any disk, partitioned or not. However, it’s much easier to get it back on a partitioned one. You know where you stored what, and each partition can be backed up exactly as it is. It’s also a lot faster to back up single partitions than entire hard drives.

Ultimately this also means a faster path to recovery. If you lose or accidentally delete important files and data, you might want to use a recovery tool like Recuva to scan for them and get them back. Recuva is even powerful enough to recover data from damaged hard drives. But no matter how powerful, scanning a whole drive is strenuous for any recovery tool. Scanning independent partitions is a lot more convenient than that, and will get you to your goal more efficiently.

6. Optimized performance

Now, let’s keep in mind that computer performance is influenced by a number of factors. Partitioning alone isn’t what makes it better or worse. However, it can contribute to optimization. It’s easier for your computer to scan, say, a 40 GB partition to fetch the system file it needs than scanning the entire capacity of your drive.

7. Improved security (possibly*)

Separate partitions can help make your system more secure. Firstly, they minimize file corruption. If one partition gets corrupted, the others should remain unaffected. And keeping in mind the previous point about backup and recovery, ‘fixing’ the damaged partition would be much easier than fixing the entire hard drive. 

Partitioning also improves security in terms of malware protection. A malicious attack on one partition is easier to deal with than malware on the whole drive. If your system partition gets infected, you can simply reinstall your OS and that should do the trick.

*Do keep in mind that partitioning can’t defend you against more advanced attacks. So make sure not to give in to a false sense of security.

What are the disadvantages of partitioning?

1. Data is still vulnerable

Yes, it’s easier to back up and recover data from independent partitions. And yes, partitioning may help protect separated files and data to a higher degree. But remember: everything is still on a single physical drive. So while digital errors and issues may be easier to deal with on partitioned drives, physical damage obviously won’t be.

If your hard drive is destroyed in some way, all data on it will be gone. That’s why, if you have crucial files on your PC, it’s important to give them the proper backup treatment before it’s too late.

2. Disbalance of space

Allocating storage space on separate partitions may be a little more tricky than you think. You may fill up one partition a lot faster than another. So on one side you’re struggling with space, and on another you have too much of it to spare. Imagine nearly filling up your system partition and then it turns out you need a lot more space for its updates than you thought.

That’s why you really have to be sure you actually have enough files of different types that you need help managing efficiently. Otherwise you’ll just create a struggle and disbalance in terms of storage.

3. Increased risk of error

If done incorrectly, partitioning can lead to more harm than good. Aside from space disbalance, there is an increased risk of incorrect partition sizes and formatting. Plus, human error is also a factor: in a moment of distraction, you may erase one partition when you meant another. Undoing such mistakes will definitely be tedious and time-consuming.

4. SSDs eliminate the need of partitioning

SSDs (solid-state drives) don’t function in the same way that HDDs do. They have faster read times and can organize files on their own. This quite literally eliminates the need for organization on your part.

Partitioning: yes or no?

The bottom line is that multiple partitions might not be necessary for the average user. But if you’re planning on storing many file types or different file and operating systems on the same PC, then you should give it a shot. It’s also an excellent solution for businesses, of course.

And if our pros and cons list isn’t enough to help you decide, you can always send us a message and we’ll help you make the right choice.

Decided to partition your hard drive?

If you’ve decided to give it a go, you definitely should make sure to do it right. 

The two most effective and reliable ways to partition are using the built-in options on Windows or investing in a dedicated partitioning tool, like the EaseUS Partition Master. Which one you'll opt for depends on your specific needs. 

Option 1 may be more suitable for users with at least some level of experience. In this case, you’d have to know exactly which steps to take without making errors. This is done in Disk Management on Windows 10/11. From there, you can select the partitions you’d like to split into different volumes of selected sizes.

If this is your first time partitioning, we highly suggest you either consult professionals for this or move on to option 2. The EaseUS partitioning software is specifically designed for beginners, with an intuitive interface helping you succeed in the process. All you need to do is pick the Partition Master package tailored to your needs and follow their guide. 

Each package offers technical support as well, and even free upgrades (to varying degrees based on your subscription). Plus, all of this is valid for not one, but two PCs.

It’s the perfect solution for a smooth and error-free partitioning process. If you want to organize your hard drives efficiently and make the most of all your space without doing irreparable damage, it’s definitely worth the investment.

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.

There are times when you see a message in Windows Defender saying, “The Threat Services has stopped, Restart it now” when you try to use it. This kind of error is usually fixed by simply clicking on the Restart now button. However, if the error still appears even after you restart your computer and you see another message that says, “Unexpected error, Sorry, we ran into a problem”, then continue reading as this post will guide you in resolving this issue in Windows Defender. Before you proceed with the given fixes below, you have to create a System Restore point first. This way, you can always undo any changes you’ve made in case something goes wrong.

Option 1 – Make sure that the Windows Defender Services are started

The Windows Defender Advanced Threat Protection service is the one that protects your computer from advanced threats by monitoring and reporting security events that happen on your computer. This is why you have to make sure that this, as well as other required services in Windows Defender, are set to their default values and are started. To do so, follow these steps:

• 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
• After opening the Services Manager, look for the following services and make sure that their Startup type is set to their default values:
  • Windows Defender Advanced Threat Protection Service – Manual
  • Windows Defender Antivirus Network Inspection Service – Manual
  • Windows Defender Antivirus Service – Manual
  • Windows Defender Firewall Service – Automatic
• You can right-click on each one of the listed services and then select Start to start them.
• And if some of the services don’t have their default values, just double-click on the Services to change the Startup types and select the correct option from the drop-down menu of the Startup type under the Properties box.
• Next, set up the Startup type of these services to Automatic and then click on the Start button if the services are not running yet.
• Now click on the Apply and OK buttons to save the changes made and then see if it fixed the problem or not.

Option 2 – Try modifying some entries in the Windows Registry

If the first option didn’t work in fixing the problem, you can try to alter some entries in the Windows Registry using the Registry Editor.

• First, tap Win + R keys to open the Run dialog box.
• Then type “Regedit” in the field and hit Enter to open the Registry Editor.
• Next, navigate to this registry path: HKLMSoftwarePoliciesMicrosoftWindows Defender
• From there, look for the “DisabledAntivirus” and “DisableAntiSpyware” DWORDS from the right pane and change each one of their values to “0”. On the other hand, if you don’t see any of these DWORDS, you can create them instead and give each one of them a 0 value.
• To create a DWORD, simply right-click on any empty space and select New > DWORD. Then name them both as “DisabledAntivirus” and “DisableAntiSpyware”.
• Afterward, set the value of the newly-created DWORDS to 0.
• Now exit the Registry Editor and reboot your PC to apply the changes made and then check if it has fixed the error in Windows Defender or not.

KMODE_EXCEPTION_NOT_HANDLED – What is it?

Some users installing or upgrading to Windows 10 experienced the theKMODE_EXCEPTION_NOT_HANDLED Blue Screen of Death (or commonly known as BSOD) error. This error can be due to different types of things, ranging from software to driver issues. When you experience this BSOD error while trying to install Windows 10, it will prompt you to restart your computer every single time you experience it. In most cases, you will also not be able to proceed with the Windows 10 set-up.

Solution

Error Causes

The “KMODE_EXCEPTION_NOT_HANDLED” error is normally caused by:

• Hardware incompatibility
• A faulty device driver or system service

Further Information and Manual Repair

You won’t be able to successfully upgrade or set up Windows 10 if you continue to encounter this BSOD error. Note that this error will always prompt your computer to restart every time it happens, preventing you from completing the Windows 10 set-up.

If you’re not tech-savvy or not capable of debugging this issue, it’s highly advisable to proceed with the basic troubleshooting techniques available in this link.

After troubleshooting, below you’ll find a few solutions to rectify the issue.

Method 1 – Check The Cause of The BSOD Error

Two common causes of the KMODE_EXCEPTION_NOT_HANDLED issue are hardware incompatibility and faulty device driver or system service.

If you experience this error, check first if any of your newly installed hardware is compatible with Windows 10. You can find the required hardware for Windows 10 from this link. 

If all your hardware is compatible with Windows 10, you might need to check the device driver or system service. Review the bug check message. If any of the drivers you have is listed in the message, either disable or uninstall them before upgrading or setting up Windows 10.

You might also find it useful to check the System Log available in the Event Viewer for other error messages that can help you figure out the driver or device that’s causing the error. Running hardware diagnostics can also be useful.

Method 2 – Disable (or preferably uninstall) Software Before Upgrading

If you’re upgrading Windows 10 from Windows 7 or Windows 8.1, you might need to disable or uninstall the software first. First, try uninstalling your Antivirus utility before starting the upgrade. Restart a few times before starting the Windows 10 installation. If you’re upgrading using the Windows 10 update, make sure that you disconnect from your Wi-Fi or Internet LAN (Ethernet) connection as soon as the download reaches 100% before attempting to start the set-up. Other users also reported that the cause of the KMODE_EXCEPTION_NOT_HANDLED issue is BitDefender. If this is what happened in your case, it will show in the error message such as KMODE_EXCEPTION_NOT_HANDLED (bdselfpr.sys). Users reported that a common solution for this is renaming the file. In the case of BitDefender, try renaming it to bdselfpr.s__. However, make sure to do this cautiously. Sometimes, renaming a file will even do more damage than good.

Method 3 – Disable/Disconnect From Hardware

If you’re connected to any general USB devices (such a smart card reader), disable it. If your computer is connected to other external devices, disconnect all of them. Examples of this include gaming controllers, printers, external hard disk, USB keys, and other non-essential devices).

Method 4 – Other Troubleshooting Steps

Other troubleshooting steps include:

• Upgrade using an .ISO file, instead of directly upgrading from Windows Update. When you do this, make sure you’re disconnected from the Internet during installation. If the process started and you forgot to disconnected, it’s best to restart the installation.
• If you’re connected to a domain while trying to set up Windows 10, disconnect and use a local account.
• If you’re using a SCSI hard disk, connect a thumb drive with the drivers for your storage device. While Windows 10 is setting up, click on the Custom Advanced Option. Using the thumb drive, use the Load Driver command to load the SCSI drive.
• Another possible cause of this error is due to BIOS incompatibility. BIOS issues can be solved by upgrading your version of your system BIOS. If you don’t know how to do this, refer to your BIOS manufacturer’s website.

Method 5 – Use A Trusted Automated Tool

If you still experience the error after doing the methods above, you might want to try a powerful and trusted automated tool to fix the job.

Error Code 28- What is it?

The error code 28 is a driver error. This is one of the many device manager error codes. When this error occurs on your computer, the following message is displayed:

“The drivers for this device are not installed. (Code 28)”

Another driver device error message you might encounter is error code 41. 

Error Causes

Error 28 occurs because of unsuccessful device driver installation. This usually happens when you try to update new drive versions on your system. It is advisable to repair this error right away as it can hamper your ability to use certain hardware. For example, if error 28 occurs due to the unsuccessful installation of the USB driver, then it if not fixed and resolved it may prevent you from using hardware devices. Unsuccessful driver installation means you either didn’t install it properly or your computer has registry issues. If it’s the registry then you must fix it without any delay because it can expose your PC to serious threats like system crash and failure. To avoid such inconvenience, repair it.

Further Information and Manual Repair

When it comes to repairing the error code 28, here’s what you can do: Simply go to the control panel and click on the Device Manager option:

• In the details pane with the list of devices, locate the device for which you want to reinstall the driver software.

Windows Terminal is a new free Microsoft terminal sort of application. When you open either Power Shell or Command Prompt in Windows they will be opened in different windows, and if you want several of each you will have several windows of each on your screen. Windows Terminal fixes this by opening each of the Instances of Command Prompt and Power Shell as separate tabs inside itself making it much easier to manage multiple instances of named applications. You can also run both Power Shell and Command prompt tabs in the same Windows Terminal. Luckily running command prompt and power shell in different tabs is not the only thing you can do. Windows Terminal lets you choose your own theme, it has emoji support, GPU rendering, split panes, and many more customizable options. Windows 11 will have Terminal as the default command-line environment for opening Power Shell or Command prompt, even Windows Subsystem for Linux (WSL)

Setting Windows Terminal as the default application

If I was successful I have managed to show you that Windows Terminal is something that you should use even if you do not or cannot upgrade to Windows 11. You can use it inside Windows 10 also. First thing is to download and install it. You can get Windows Terminal from the official Microsoft website here: Windows Terminal page After download and installation are completed, open the Terminal app and select the down arrow menu, click Settings. Alternatively, you can use CTRL + + shortcut. Inside Settings by default Default Terminal application would be set to Windows Console Host Click on the Default Terminal application to bring a drop-down menu and choose Windows Terminal from the list. Now by default once opened Windows Terminal will use Power Shell as the default profile, however, you can change this by clicking on the drop-down for the default profile where you can choose between Command Prompt, Power Shell, Windows Power Shell, or Azure Cloud Shell. Pick one that you prefer, click on Save and it will be opened as default on the next run.
