Guide How to Remove PCOptimizerPro

If you got an error message saying, “Windows could not start the Windows Update service on Local Computer, Error 87. The parameter is incorrect” while you were trying to start the Windows update service on your computer, then this post could help you resolve the problem. Along with this error, you might also get any of these error codes such as 0x80240034, 0x80244019, 0x80070643, and so on. Aside from these error codes, you will also notice that the Windows Update service has been stopped. To fix this issue, here are a couple of suggestions that might help but before you go on, you need to create a System Restore point first.

Option 1 – Try checking Services Dependencies

Dependencies of a Windows Service in Windows 10 are when windows services depend on other services. Such is the case with the Windows Update service – it also depends on three different services such as the Remote Procedure Call or RPC service, DCOM Server Process Launcher, and the RPC Endpoint Mapper. Meaning to say, if two of these services are not working as expected, then the dependant service will also be affected. This could be the reason why the Windows Update service could not start.

• Tap the Win + R keys to open the Run dialog box.
• Next, type “services.msc” in the field and hit Enter to open Windows Services.
• From the list of Services, look for the following services:
  • Remote Procedure Call (RPC) Service
  • DCOM Server Process Launcher
  • RPC Endpoint Mapper
• After you find these services, double click on each one of them and check whether the Startup type for all is set to Automatic and the Service status is set to Running or not.
• If the service status is not running, then click the Start button. Afterward, check if you can now run the Windows Update service.

Option 2 – Check the Background Intelligent Service and the Cryptographic Service

• Tap the Win + R keys to open the Run dialog box.
• Next, type “services.msc” in the field and hit Enter or click OK to open Services.
• From the list of Services, look for the following services and make sure that their Startup type is as follows:
  • Background Intelligent Transfer Service – Manual
  • Cryptographic Service ­– Automatic
• After that, check if the Service status of the listed services above is set to Running. If they’re not, click on the Start button to start these services and then check if you can now enable the Windows Update service or not.

Option 3 – Reset Windows Update components

If the first two options did not work then you might want to reset the Windows Update components manually. Follow the steps below to reset them.

• Open Command Prompt with admin privileges.
• After that, type each one of the following commands and hit Enter after you key in one after the other.
  • net stop wuauserv
  • net stop cryptsvc
  • net stop bits
  • net stop msiserver

Note: The commands you entered will stop the Windows Update components such as Windows Update service, Cryptographic services, BITS, and MSI Installer.

• After disabling WU components, you need to rename both the SoftwareDistribution and Catroot2 folders. To do that, type each one of the following commands below, and don’t forget to hit Enter after you type one command after the other.
  • ren C:WindowsSoftwareDistribution SoftwareDistribution.old
  • ren C:WindowsSystem32catroot2 Catroot2.old
• Next, restart the services you’ve stopped by entering another series of commands. Don’t forget to hit Enter after you key in one command after the other.
  • net start wuauserv
  • net start cryptsvc
  • net start bits
  • net start msiserver
• Close Command Prompt and reboot your PC.

Option 4 – Run the Windows Update Troubleshooter

If resetting the Windows Update components didn’t work, you could also try running the Windows Update Troubleshooter as it could also help in fixing any issues related to Windows Update including this one. To run it, go to Settings and then select Troubleshoot from the options. From there, click on Windows Update and then click the “Run the troubleshooter” button. After that, follow the next on-screen instructions and you should be good to go.

Option 5 – Try removing a value from the Windows Registry

If running the Windows Update troubleshooter didn’t help and you receive a message instead saying, “Service Registration is Missing or Corrupt”, you can try to remove a value from the Windows Registry.

• Tap the Win + R keys to open the Run dialog box.
• Then type “Regedit” in the field and hit Enter to open the Windows Registry.
• Next, navigate to this path: HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsSelfHostApplicability
• From this path, look for a value named “ThresholdOptedIn” and if you find it, delete it.
• Exit the Registry Editor and see if you can now enable the Windows Update service.

As you know, Windows programs depend on several operations to get executed and at the same time, there are also numerous parameters that have to be fulfilled for a program to get executed. However, based on some reports, there was an error when some users tried to run a program. This error says, “The application was unable to start correctly (0xc00007b)”. There could be various reasons why this error occurs but the main one is most likely due to an x86 application that is not compatible with the x64-based operating system. To fix this problem, you can run the Check Disk utility or reinstall the application or the Microsoft .NET Framework. You can also try reinstalling DirectX or replace the corrupted DLL file(s). For more details, refer to the given options below.

Option 1 – Try running the Check Disk utility

• In the Windows Search box, type “command prompt” and from the search results, right-click on Command Prompt and select “Run as administrator”.
• After opening Command Prompt, type this command and tap Enter: chkdsk <Partition Letter>: /f
• The command you entered will start to check for errors and fix them automatically. Else, it will throw an error message saying, “Chkdsk cannot run because the volume is in use by another process. Would you like the schedule this volume to be checked the next time the system restarts? (Y/N)”.
• Tap the Y key to schedule Disk Check the next time your computer restarts.

Option 2 – Re-enable the Microsoft .NET Framework

You could also try to disable the Microsoft .NET Framework then enable the latest version of the .NET Framework on your PC and check if the error is fixed

Option 3 – Try to reinstall the program

There are times when some supporting module for your application under the hood could have messed up the application where you get the error. To fix this, you have to uninstall the program and then download its latest version from its official site and then install it again. Once you’re done, run the application and see if the error is fixed.

Option 4 – Run System File Checker scan

If reinstalling the program didn’t work, you can also try running the System File Checker or SFC scan to fix the error. System File Checker is a command utility built into your computer that helps restore corrupted files and missing files. Refer to the following steps to run it:

• Hit the Win + R keys 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:

1. Windows Resource Protection did not find any integrity violations.
2. Windows Resource Protection found corrupt files and successfully repaired them.
3. Windows Resource Protection found corrupt files but was unable to fix some of them.

• Reboot your computer.

Option 5 – Try running the DirectX Diagnostic Tool

Since the error has something to do with the DirectX Graphics APIs, you can run the DirectX Diagnostic tool to resolve the problem.

Option 6 – Try updating or re-installing DirectX

If the DirectX Diagnostic tool didn’t work, you can try to update or reinstall DirectX instead. This can help in fixing the problem because when you reinstall or update DirectX, it will replace the incompatible or corrupted components of DirectX from your computer.

Windows PowerShell is a powerful tool inside the Windows environment often overlooked by typical users which is a great mistake since it can offer a large array of functionality and usability and if used well can offer a unique working experience. Today we will be using PowerShell to turn the WEB camera off so it can not be accessed, completely disabling it for use. You might want to do this for security reasons or just want to learn few new things. Whatever your reason might be, I am welcoming you to this tutorial and please do keep reading.

Finding device ID

In order to disable the WEB camera first thing we need to do is to find a matching device ID. We will find this value inside the device manager, so press ⊞ WINDOWS + X to open the secret menu. In the menu choose device manager and click on it. When the device manager opens, expand the Imaging devices or Cameras section. Right-click Integrated Camera or the primary webcam, and click Properties. Go to the Details tab. Under the Property section, click to select Matching device ID from the drop-down. Right-click the value and select Copy The next step is to download and install Windows Driver Kit (WDK)

PowerShell script

Create and run a PowerShell script with the following parameters/values to disable the camera. Substitute the <FOLDER> placeholder with the actual name of the folder where your copy of Devcon is residing

$id = (Get-CimInstance Win32_PnPEntity |

where caption -match '<PRIMARY CAMERA>').pnpDeviceID

$ppid = "{0}{1}" -f '@',$id

Set-Location c:\<FOLDER>

Devcon status $ppid

Devcon disable $ppid

Devcon status $ppid

To enable the camera device, run the command below in PowerShell:

devcon enable $ppid

Often when we connect to the internet were browsing indexed pages through some well-known search engine, usually Google. But beneath the so-called normal internet lurks deep and dark web. You might have heard of the deep web and dark web if you have some geeky friends and we are here to explain what exactly is the deep and dark web. The first thing to know is that the deep and dark web is not the same thing and they coexist separately from one another, you could say that beneath the deep web lies the dark web, yet another layer of the internet. So let us explore first the deep web. What is exactly a deep web?

Deep web, hidden web, or invisible web

as sometimes referenced are part of worldwide web not indexed by search engines, meaning that engines do not basically see and index content of deep web sites. The content of the deep web is hidden behind HTTP forms and includes many very common uses such as webmail, online banking, private or otherwise restricted access social-media pages and profiles, some web forums that require registration for viewing content, and services that users must pay for, and which are protected by paywalls, such as video on demand and some online magazines and newspapers. The content of the deep web can be located and accessed by a direct URL or IP address but may require a password or other security access to get past public website pages. While it is not always possible to directly discover a specific web server's content so that it may be indexed, a site potentially can be accessed indirectly (due to computer vulnerabilities). To discover content on the web, search engines use web crawlers that follow hyperlinks through known protocol virtual port numbers. This technique is ideal for discovering content on the surface web but is often ineffective at finding deep web content. For example, these crawlers do not attempt to find dynamic pages that are the result of database queries due to the indeterminate number of queries that are possible. It has been noted that this can be (partially) overcome by providing links to query results, but this could unintentionally inflate the popularity of a member of the deep web.

Dark WEB

The dark web is the World Wide Web content that exists on darknets: overlay networks that use the Internet but require specific software, configurations, or authorization to access. Through the dark web, private computer networks can communicate and conduct business anonymously without divulging identifying information, such as a user's location. The dark web forms a small part of the deep web, the part of the Web not indexed by web search engines, although sometimes the term deep web is mistakenly used to refer specifically to the dark web. The darknets which constitute the dark web include small, friend-to-friend peer-to-peer networks, as well as large, popular networks such as Tor, Freenet, I2P, and Riffle operated by public organizations and individuals. Users of the dark web refer to the regular web as Clearnet due to its unencrypted nature. The Tor dark web or Onionland uses the traffic anonymization technique of onion routing under the network's top-level domain suffix .onion.

Dark & Deep WEB difference

The dark web has often been conflated with the deep web, the parts of the web not indexed (searchable) by search engines. The dark web forms a small part of the deep web but requires custom software in order to access its content. This confusion dates back to at least 2009. Since then, especially in reporting on Silk Road, the two terms have often been conflated, despite recommendations that they should be distinguished. Darknet websites are accessible only through networks such as Tor ("The Onion Routing" project) and I2P ("Invisible Internet Project"). Tor browser and Tor-accessible sites are widely used among darknet users and can be identified by the domain ".onion". While Tor focuses on providing anonymous access to the Internet, I2P specializes in allowing anonymous hosting of websites. Identities and locations of darknet users stay anonymous and cannot be tracked due to the layered encryption system. The darknet encryption technology routes users' data through a large number of intermediate servers, which protects the users' identity and guarantees anonymity. The transmitted information can be decrypted only by a subsequent node in the scheme, which leads to the exit node. The complicated system makes it almost impossible to reproduce the node path and decrypt the information layer by layer. Due to the high level of encryption, websites are not able to track the geolocation and IP of their users, and users are not able to get this information about the host. Thus, communication between darknet users is highly encrypted allowing users to talk, blog, and share files confidentially.

Darknet

The darknet is also used for illegal activity such as illegal trade, forums, and media exchange for pedophiles and terrorists. At the same time, traditional websites have created alternative accessibility for the Tor browser in an effort to connect with their users. ProPublica, for example, launched a new version of its website available exclusively to Tor users.

What is Windows ImageAcquisition High CPU & Disk usage? The Windows Image Acquisition is the driver model in charge of the communication between the graphics hardware and the operating system. There are times when it causes high disk and CPU usage in Windows 10 systems which results in slow performance of the computer. To fix this issue, read on as this post will help you in addressing the problem. The cause of this problem might have something to do with the hardware or the drivers. And so if your computer becomes slow because of the Windows Image Acquisition process, here are some suggestions that might be of help. You can try to restart the Windows Image Acquisition service, run a System File Checker Scan, disconnect & reconnect imaging hardware as well as update and reinstall the drivers and updating the graphics drivers. For a complete set of instructions, follow the given options below.

Option 1 – Try restarting the Windows Image Acquisition Service

• Tap the Win + R keys to open the Run dialog box.
• Then type “services.msc” in the field and hit Enter to open the Windows Services Manager.

In the last article, we have covered various advantages of Apple hardware over Windows PC, however, PC has their own strengths and advantages over MACs as well. Join us as we explore why would you choose Windows PC over MAC.

Hardware customization

If you like to customize and build your own hardware and customize your existing computer then MACs are out of the picture, on other hand, computers based on Windows operating system are much more flexible in terms of customization.

While Apple hardware is locked and only allows small changes to it, computers running on Windows are free and open to various upgrades and modifications so if you like to play with hardware Windows is your platform.

Gaming

There are games on MAC true but their numbers can not compare to games available for the Windows platform. On top of that, most latest and best gaming hardware is not even available on Apple platforms so if you plan to game in high resolutions and play the latest games there really is no option other than Windows.

Windows Platforms also has multiple emulators that you can use to play games from other older platforms and Microsoft since it owns Xbox has some great plans for both PC and Xbox gaming.

Software back compatibility

Since the introduction of the new MAC OS X, apple really lost a lot of application back compatibility, and a lot of old legacy software can not be run on modern Apple computers. Windows on the other hand have always tried and succeeded in keeping maximum compatibility with older and legacy software.

Also on the Windows platform, there is a lot of community support for old and legacy software so even if it is not officially supported it is backed up by the community.

Software variability

In terms of where can you find the most different software, you need to look no further than the Windows platform. How Windows itself has great backward compatibility and a lot of developers are using it to create new software thanks to Visual Studio and .NET Windows has cemented itself as a platform with the most available software.

The popularity of Windows as the home operating system and as a gaming platform has made it quite interesting in eyes of various developers and tons of small applications are made daily for it. Windows 11 has also brought native android support to it and that has just expanded its already impressive catalog of applications.

Freedom of choice

Overall Windows PC is most appealing for users that like to be able to choose everything, from hardware components to software they would like to use. No other platform will give you larger freedom of choice and better personalization options.

Upgrading your Windows computer may not always go as expected as you could end up getting some error messages along the way. One of the error messages you can encounter is the “STOP 0XC000021A or STATUS_SYSTEM_PROCESS_TERMINATED” error. This error indicates that is some security issue within the Windows operating system. It could be that the system files have an issue and they have been modified incorrectly. Although this does not necessarily mean that malware is behind the modification, one of the applications you installed recently might have something to do with the problem. The application might have modified or corrupted some of the core system files. When you encounter this error, you will see a blue screen along with the following error message:

“Your PC ran into a problem and needs to restart. We’re just collecting some error info, and then we’ll restart for you. (0% complete) If you’d like to know more, you can search online later for this error: 0xc000021a”

This error pops up when a user-mode subsystem like the WinLogon or the Client Server Run-Time Subsystem or CSRSS has been compromised fatally and security can no longer be guaranteed in the system. Thus, the operating system switches to kernel mode, and Windows won’t be able to run without the WinLogon or the Client Server Run-Time Subsystem. This is why it’s one of the few cases where the failure of a user-mode service can shut down the system. To resolve the issue, here are some fixes that might help.

Option 1 – Uninstall programs you installed lately

• In the search box, type in “control” and then click on Control Panel (desktop app) among the search results.
• After that, select Programs and Features from the list which will give you a list of all the programs installed on your computer.
• From there, look for the concerned program and select it and then uninstall it.

Note: If you have downloaded the app from the Windows Store, you can simply right-click on it from the application list and then uninstall it.

Option 2 – Perform System Restore

Performing System Restore can also help you fix the “STOP 0XC000021A or STATUS_SYSTEM_PROCESS_TERMINATED” error. You can do this option either by booting into Safe Mode or in System Restore. If you are already in the Advanced Startup Options, just directly select System Restore and proceed with the next steps. And if you have just booted your PC into Safe Mode, refer to the steps below.

• Tap the Win + R keys to open the Run dialog box.
• After that, type in “sysdm.cpl” in the field and tap Enter.
• Next, go to the System Protection tab then click the System Restore button. This will open a new window where you have to select your preferred System Restore point.
• After that, follow the on-screen instructions to finish the process and then restart your computer and check if the problem is fixed or not.

Option 3 – Run the System File Checker or SFC 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 that might be the cause why you’re getting the “STOP 0XC000021A or STATUS_SYSTEM_PROCESS_TERMINATED” error. 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:

1. Windows Resource Protection did not find any integrity violations.
2. Windows Resource Protection found corrupt files and successfully repaired them.
3. Windows Resource Protection found corrupt files but was unable to fix some of them.

Option 4 – Rebuild the BCD and fix MBR

Rebuilding the BCD can help you in fixing the “STOP 0XC000021A or STATUS_SYSTEM_PROCESS_TERMINATED” error.

• 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.
• Next, select Command Prompt and type in the commands below one by one, and tap Enter right after you do so.
• exe /FixMbr
• exe /FixBoot
  • exe /RebuildBcd

The commands you entered should rebuild the BCD and repair MBR.

Option 5 – Run the CHKDSK utility

You can also run the Chkdsk utility to resolve the problem. If your hard drive has issues with integrity, the update will really fail as the system will think that it’s not healthy and that’s where the Chkdsk utility comes in. The Chkdsk utility repairs hard drive errors that might be causing the problem.

• Open Command Prompt with admin privileges.
• After opening Command Prompt, execute the commands listed below, and don’t forget to hit Enter right after you type in each one of them.
• chkntfs /t
• chkntfs /t:10

People are becoming more and more concerned with their privacy and Facebook's flagship messaging application is caught between it all. While still widely popular it has becoming to lose its ground due to many unanswered questions about privacy encryption. Lucky for all of us there are alternatives for more secure messaging.

SIGNAL

Arguably the most secure of all well-regarded messaging apps, Signal is the favorite of the European Commission, as well as newsrooms around the world. While Signal doesn’t disclose how many daily or monthly users the app has, Google’s Play Store says it has been installed more than 50 million times. While using Signal, each voice or video call connected through the app includes full end-to-end encryption. Signal takes an extra step by hiding message metadata so that the location of the original message is missing. While it asks for your mobile number, that number isn’t used with your profile. Instead, it acts as a numeric username. Once registered, you will find 1-1 chat, audio, and video calls, disappearing or “secret” chats, and a privacy lock so nobody can access the app even if they have your phone. Best of all, it’s completely free to use.

TELEGRAM

One of the biggest competitors to Facebook Messenger (and WhatsApp), Telegram is a very strong alternative. With more than 400 million users, it offers an interface that should feel right at home for anyone coming from Messenger. Telegram offers some huge benefits over Messenger, including features like groups that can hold up to 200,000 members for a chat. There is no limit on your media or chat size, and you can share all types of files between users and in groups. From a privacy standpoint, Telegram has robust security, but it is worth noting that only “secret” messages are end-to-end encrypted and can self-destruct. Non-secret messages can be stored on Telegram’s servers so you can pick them up between your devices quickly. That’s a consideration worth knowing prior to making Telegram your default Messenger replacement. Telegram is free across all platforms.

THREEMA

Rising in popularity, Threema is another privacy-focused alternative that has quickly become a competitor to Facebook Messenger. This paid service ($2.99 on both App Store and Play Store) is a pay-once, use forever option. Once you pay the small fee, you gain all of Threema’s touted privacy options, like open-source end-to-end encryption for both messages and calls. Like Signal, Threema won’t require you to link any phone numbers or emails to your account. All chats are handled anonymously, and the service generates a random user ID when you first open and register for the app. No data is collected from any of your chats and no ads are shown. The Swiss-made app does have its own servers hosted in Switzerland, which do not store any chat messages. Another privacy benefit of Threema is the notion that all of your contact lists, groups, and user profiles are hosted on your device, not on the Swiss servers. Because of that, Threema can once again state that none of your personal info is stored anywhere they have access.

A new update to popular Microsoft PowerToys has brought a few new features that are aimed at speeding up the workflow. The first new feature that was slid in is Always on top utility. With this cool utility, you can keep the window as the name suggests, always on top of other windows. To enable this cool feature all you have to do is press the key combination of ⊞ WINDOWS + CTRL + T and an active window will be now always on top of all other windows. To reverse and unlock this window from being always on top just press key combination again. A second new feature is a really great one and my favorite thing to happen in power toys. Often we are making the search in our browsers to find stuff, things, maybe some explanations, information, etc. The newest update in power toys brings this to a whole new dimension. While you are on PC you just simply need to type ?? followed by questions like: ?? When doctor strange 2 is coming out and that will launch your default browser with your chosen search engine and provide you with the answer. Third and final thing is G-code support in the file explorer preview pane and thumbnails, meaning that if you work with CNC equipment you can now have a thumbnail preview of the code itself inside File Explorer. And that’s it for now, thank you for coming and reading, Take care and I hope to see you next time.
