Disable overlays
If you’re using a program like Discordthat has an overlay, you’ll want to disable it as it may be causing the graphic error
If you are trying to start a service using the Windows Services Manager but you got an error message stating, “The executable program that this service is configured to run in does not implement the service”, then you’ve come to the right place as this post will provide you instructions on how you can fix this error.
Since almost all program requires service to run on your computer, if the service is not listed in the corresponding registry key, then you will most likely encounter this error on your Windows 10 computer. Here’s the entire content of the error message:
“Windows could not start the service on Local Computer. Error 1083: The executable program that this service is configured to run in does not implement the service.”
To fix this error, you have to add the service name in the respective host in the Registry Editor, and to do that, here are some steps you need to take on.
Step 1: The first thing you have to do is to take note of the service name that’s given in the error message. For instance, you get the “Windows Management Service.
Step 2: Next, you need to open the Services Manager by tapping the Win + R keys and typing “services.msc” in the Run dialog box, and then tapping Enter.
Step 3: After opening the Services Manager, look for the Windows Management Service and once you see it, double click on it. This will open a new mini window.
Step 4: From the newly opened window, copy the Service name and the Path to executable under the General tab. If the path to the executable is displayed as “C:/Windows/system32/svchost.exe -k netsvcs –p”, you need the “netsvcs” part only. Note that it can be different for different services and you need the part that comes after “-k”.
Step 5: Now tap the Win + R keys again to open Run utility and type “Regedit” in the field and click OK to open the Registry Editor.
Step 6: After that, navigate to the following registry path:
Step 7: From the given registry path, look for a key named “REG_MULTI_SZ” located on your right-hand side. This key is named after the “Path to executable” part. For instance, you should see “netsvcs”.
Step 8: Double click on the REG_MULTI_SZ key and enter the Service name that you’ve copied earlier and then write it down at the end of the preset list.
Step 9: Now save the changes you’ve made and try to open the program or run the service again.
If you got the FAULTY_HARDWARE_CORRUPTED_PAGE Blue Screen error on your Windows 10 computer then it is most likely caused by various factors. It could be caused by an incomplete installation or uninstallation of some applications or program, or it could also be caused by some exploit that intervenes with the normal functioning of the computer, as well as bad sectors on the hard disk, damaged system files, malfunctioned system drivers, modified Windows Registry files, or a Blue Screen occurrence during a Windows Update and many more. Getting this bug check means that a single-bit error was found on this page. It also indicates that this is a hardware memory error and to resolve it, you need to follow the suggestions laid out below but before that, it is recommended for you to create a System Restore Point first so that if anything goes wrong, you can always go back to the previous state.
Option 1 – Run a Memory Check to test RAM
Since the problem might have something to do with hardware memory, you need to test RAM by running a Memory Check using the Windows Memory Diagnostic. Refer to these steps to do so.
Tap the Win + R keys to open the Run dialog box.
Then type “mdsched.exe” in the field and hit Enter to open the Windows Memory Diagnostic.
After that, the Windows Memory Diagnostic will give out two options such as:
Restart now and check for problems (recommended)
Check for problems the next time I start my computer
Select any of the given options. After that, your computer will restart and check for memory-based issues upon the restart. If there are any issues, it will automatically them.
Option 2 – Run the System File Checker
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 with good system files that might be the cause why you’re getting the FAULTY_HARDWARE_CORRUPTED_PAGE Blue Screen 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:
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.
Option 3 – Check for conflicting or incompatible programs by putting your PC in a Clean Boot state
As mentioned, the FAULTY_HARDWARE_CORRUPTED_PAGE Blue Screen error might be caused by some problematic programs that clash with your existing operating system. Several users reported that numerous programs that are supposedly designed to enhance computer performance are causing conflict in the system instead. 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” checkbox 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” checkbox.
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 4 – Update or rollback drivers
If the first few options 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.

The Error Code 0x800F0923 is one that appears only when attempting to update from older versions of Microsoft Windows to Microsoft Windows 10. This error does not occur with every install and is believed to be the result of a driver incompatibility issue. It is unclear which specific drivers are having the compatibility issues, though it is widely believed that DuplexSecure's SPTD drivers are the ones at fault. When operating correctly, without errors, the update process should not take longer than 30 minutes.
Common symptoms include:
Error message window/pop-up during the install process, giving the Error Code 0x800F0923
Inability to install and update from older versions of Microsoft Windows to version 10
Solution
Error Causes
There are various relevant factors associated with the error code 0x800F0923 incompatibility issue in Windows 10 installation/upgrade. These factors include but are not limited to:
The Operating System (OS) upgrading does not support older hardware.
Your computer’s specs did not meet the minimum requirements.
Not enough hard disk space.
The new software might lack software drivers for older hardware
Further Information and Manual Repair
Microsoft has recently released its Windows 10 operating system. While there are still a few kinks to be worked out, overall the reviews have been positive. As with any new Microsoft update, compatibility issues can arise. If you are unsure whether your current PC will be able to handle the new Windows 10, here is an easy way to check your system.
Method 1: Check if your computer is compatible
Locate the “Get Windows 10” application icon in your notification tray (bottom right corner of your screen, white Windows logo).
Right-click on this icon, then select the “check your upgrade status” option.
Be prepared for the menu to take a few minutes to open.
Click on the menu on the upper left-hand corner of this new dialog box. (It looks like three blue horizontal lines)
Select “check your PC”
After the system checks for compatibility, it will let you know whether or not your PC has the appropriate drivers, etc. (Keep in mind that this is not a foolproof method for checking compatibility status).
Method 2: Download or upgrade your drivers/software
If you have already attempted to update to Windows 10, and have received the Error Code 0x800F0923, this is the simplest way to solve the issue yourself.
1. Open the “Get Windows 10” application.2. Open the menu in the upper left corner, looks like three blue lines.3. Select “Check your PC”.4. The system will tell you which drivers are incompatible.5. Go to the Microsoft Support website to install and/or update the drivers that proved to be an issue.6. Once the driver issue is corrected, retry the Windows 10 update.
Method 3: Create space on your computer
If your computer does not have sufficient space to accept the upgrade, you might want to clear up some space on your computer. Here’s how to do it.
If you have not attempted to install Microsoft Windows 10 yet, it is a good idea to check your system's compatibility prior to installing. While it is not absolutely necessary, it will save time and frustration. Microsoft Support suggests contacting them directly if you are unable to solve your driver compatibility issues, or if the above do-it-yourself method is unsuccessful.
To resolve this compatibility issue and get your upgrade going use a powerful and user-friendly tool to clean up the problem.
Click here to download Restoro.
Users should also be aware that those who choose to upgrade to Windows 10 have 30 days in which they may decide that they would rather use their old system. However, reverting back to the older system may not be a smooth process, and some data could be lost.
While running your Windows 7/Windows Server 2008 R2, your system suddenly stops responding out of complete randomness and you see an error message popping up which says something like this:
The stop error 0x00000050 signifies that there’s a PAGE_FAULT_IN_NONPAGED_AREA problem. If you’ve seen this error on different occasions then you will find the parameters in the message to be varying. That is because they are dependent on your PC’s configuration. Not all Stop errors "0x00000050” occur due to a single issue.
However, the most common problem which is encountered which results in the stop error popping up is due to a pool corruption occurring in the Srvnet.sys file.
This issue might be caused because of software incompatibility or a defective physical memory which resulted in requests for data for a hardware driver or service which was not found in the memory.
If you find the error occurring after you’ve installed a new application or a device driver then you should access Safe Mode and uninstall, disable or remove that application or driver.
Further Information and Manual Repair
In order to fix this issue, you should try booting your computer to the “Last Known-Good Configuration” as listed during startup.
For this you have to follow the below-mentioned steps:
Start your system.
When you see the message which says “For Troubleshooting And Advanced Startup Options For Windows, Press F8” hit F8 and proceed.
Use the up and down arrow keys to highlight “Last Known-Good Configuration” and hit enter (This method will only work if your system boot was not successfully carried out ever since you made any specific changes).
When you are starting the computer, press F12 and proceed with the PSA/32 Bit Diagnostics.
Do the following so that a clean boot can be performed:
Go to the Start menu when the Windows 7 desktop shows up.
On the search bar, type “msconfig” and hit search.
Disable all the applications which are listed on the “Startup” tab.
Now head over to the “Services” tab and mark the option which reads "Hide all Microsoft Service".
Select the “Disable All Services” option.
Apply the changes by clicking on “Apply” then restart your PC. You should now check the performance of your computer. If you don’t see a BSOD then you start re-enabling all the Services and Startup applications one by one until you finally figure out which one is causing the BSOD to appear.
As you know, the Taskbar is one of the integral parts of the Windows desktop and it has been there since the release of Windows 1.0 and up until now with Windows 10. Since then, Microsoft has been modifying the Taskbar with a new design which makes it a home for new features such as Windows Search, Task View, and many more. However, there are times when you may that the Taskbar has disappeared or has stopped responding. If you experience either one of these scenarios, read on as this post will walk you through what you can do to resolve the problem.
Here are some suggestions you can check out to resolve the issue with the Taskbar in Windows 10 but before you proceed, make sure that you create a System Restore point first. To do that, follow these steps:
In the Start search, type in “create a restore point” and click the entry “System Properties”.
Next, select the main system drive under Protection Settings and click on the Configure button.
After that, select the “Turn on system protection” option and then click on the Apply and OK buttons to save the changes made.
Once you’ve created a System Restore point, refer to the troubleshooting steps below to fix the Taskbar in Windows 10.
Option 1 – Try to restart the Explorer process
This may sound really basic but it actually is a proven method to fix the Taskbar issue. So if anything gets stuck on the system tray or the Taskbar, you can always fix it by restarting the explorer.exe. How? Refer to these steps:
First, right-click on the Taskbar and select the Task Manager.
After opening the Task Manager, go to the Processes tab and look for the process named “Windows Explorer”.
Then right-click on that process and select the option to Restart. Afterward, you should now be seeing the Taskbar as this will reload the whole Windows Shell.
Option 2 – Unhide the Taskbar using the Settings app
It is possible that the Taskbar could be hidden so you can try to unhide it using the Settings app.
Tap the Win + I keys to open Settings.
After that, go to Personalization > Taskbar.
From the main section, make sure that the “Automatically hide the task in desktop mode” is toggled to the off position. However, if it’s already off then proceed to the next options below.
Option 3 – Make sure that you are not in Tablet Mode
Since Windows 10 is designed to work on both desktop and mobile devices, it could be that your computer has slipped into Tablet Mode which explains why you’re not seeing the Taskbar. To check if your computer is really in Tablet Mode, follow these steps:
Go to the Start menu and select Settings.
Next, select the System setting and from the left pane select the Tablet Mode.
From there, make sure that the buttons next to the options given below are set to the off position:
Hide app icons on the taskbar in tablet mode

Option 4 – Try to check the Projection Settings
You might also want to check the Projection settings as it could be the reason why Taskbar has disappeared.
Tap the Win + P keys to open the Windows Projection settings.
Next, make sure that you select the “PC screen only” option and then check if your Taskbar has now appeared or not.
Nvidia GeForce RTX is a high-end professional visual computing platform created by Nvidia, primarily used for designing complex large-scale models in architecture and product design, scientific visualization, energy exploration, and film and video production. Nvidia RTX enables real-time ray tracing.
Historically, ray tracing had been reserved for non-real-time applications (like CGI in visual effects for movies and in photorealistic renderings), with video games having to rely on direct lighting and precalculated indirect contribution for their rendering.
RTX facilitates a new development in computer graphics of generating interactive images that react to lighting, shadows, and reflections. RTX runs on Nvidia Volta-, Turing- and Ampere-based GPUs, specifically utilizing the Tensor cores (and new RT cores on Turing and successors) on the architectures for ray-tracing acceleration.
Advantage in games
With incredible lighting and shadows, reflection, better smoke, and water effects, and more, RTX has managed to place awesome real-time effects on your desktop all that’s to Nvidia technology behind it.
Of course, in order to harvest this kind of technology and features game itself needs to support and have RTX in it, you can not turn RTX in just any game, the game itself must have technology build in it.
Therefore we are bringing you the list of all RTX games you can find currently on the market so you can enjoy at the moment best graphics a PC can offer
So, you have finished with work, game, movie, music, email, or whatever on your PC, you look at the clock, it is late, you decide to go to sleep or outside, you click on the power button and choose shutdown. Now when a PC is shut down you feel good and go with your business but the next time you power it up you get the same error like the computer never really shut down in the first place. You wonder why and reboot it, just in case and all of the sudden error is gone.
If something similar has happened to you or you had the feeling that after shutting down your computer has not really felt like shutting it down, do not seek professional help, everything is OK with you because when you click on shut down, your computer does not really shut down!
Truth is that Microsoft has changed how to shut down works and how rebooting works in Windows with an update but has not publicly said anything about it so some users may experience this feeling of not shutdown phenomenon and might even think there is something wrong with their PC.
Why this change?
A few years ago shutdown button and option in Windows were really shutting down OS, but things changed when Microsoft wanted to increase boot-up speed. Now when that decision was made shutdown option was changed. So, what was changed? Well in order to increase Windows booting time, the shutdown will now turn off power to PC components and it will look like everything is indeed shutdown but the Windows kernel will actually be saved to a hard drive with all settings and just awaken once the PC is turned back ON. This will result in all errors and other stuff being just still present same as they were once the system was instructed to be turned off.
Rebooting your PC will now clear kernel and file from the hard drive and you will get a clean system startup without any issues tied with the kernel itself.
Workaround
Now that we know why and what change has been made to Windows logical question is can we shut down our PC at all properly? Luckily for us, the answer is yes and we will not need any external application to do it, we can still do it inside Windows itself and it is quite quick and easy.
Bringing back the old shutdown
In order to bring the old shutdown functionality of your PC please follow the instructions but be aware that by doing this your PC will boot a little bit slower since it will have to load the kernel from scratch each time computer is turned ON.
First thing is to go to settings and go to System
Then once you are inside the system, navigate to the power and sleep and click on it to select it. Once you have it selected to all the way to the right and click on additional power settings.
When you click on advanced power settings you should be led to the control panel's power options. Inside this panel click on top left link where it says Choose what the power button does.
Inside options, you will need to untick the box next to Turn on fast startup (recommended), this option has been ticked ON by the Windows update and probably without notifying you. Option means exactly what was described, it will save kernel state on the hard drive for faster boot time but sadly it can cause some issues since it will never be reloaded from 0.
If you are unable to uncheck the box click on the text beside the shield icon that says: Change settings that are currently unavailable (you will have to be logged in as administrator).
Conclusion
Altho turning off fast startup and shutting down the PC completely will for sure extend your bootup time I still believe that it is the right choice since sometimes a lot of clutter and bad things accumulate over time inside the OS and can cause a vast variety of problems in a long run. So stay safe and shut down that PC as it used to be in the past.
What is Active History? A new feature has been introduced in Windows 10 that allows users to stay connected to their tasks across their devices. This new feature is called “Windows Timeline” and using this feature, users could continue their tasks all over their Windows 10 computers as well as on devices that run Android and iOS as well.
This new feature was included in Microsoft Launcher and Microsoft Edge on Android devices as well as in Microsoft Edge for iOS devices. In order for the feature to work, you have to send either Basic or Full data and diagnostics of your computer to Microsoft which would sync it all over your devices with the help of the cloud. And now since all your data is stored on your Windows 10 computer and with Microsoft under your account, it is easier for you to access the back and start where you left off. This kind of option is called Active History. In this post, you will be guided on how you can permanently disable Active History using either the Windows Registry or Group Policy.
Before you go on further, it is recommended that you create a System Restore Point first in case anything goes wrong. This is a precautionary measure you must take so that you can easily undo the changes you’ve made. After creating a System Restore Point, proceed to the given instructions below.
Option 1 – Disable Active History via Registry Editor
Tap the Win + R keys to open the Run dialog box and type in “Regedit” in the field and hit Enter to open the Registry Editor.
Next, navigate to this registry key: ComputerHKEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftWindowsSystem
From there, check if you can find a DWORD named “PublishUserActivities”. If you can’t find this DWORD, just create one with the same name and make sure that the base is selected to Hexadecimal.
After that, double-click on the DWORD and change its value from 1 to 0 to disable Active History.
Restart your computer to apply the changes you’ve made successfully.
Option 2 – Disable Active History via Group Policy Editor
Note that this second option won’t work if you are using the Home edition of Windows 10. This is because the Group Policy Editor does not come with Windows 10 Home. So if you are not using Windows 10 Home, follow the given steps below.
Tap the Win + R keys to open the Run box.
Then type in “gpedit.msc” in the field and hit Enter to open the Group Policy Editor.
Next, navigate to this path: Computer ConfigurationAdministrative TemplatesSystemOS Policies
After that, double click on the configuration listing named “Allow publishing of User Activities” to open the configuration page which has the following description:
“This policy setting determines whether User Activities can be published. If you enable this policy setting, activities of type User Activity are allowed to be published. If you disable this policy setting, activities of type User Activity are not allowed to be published. Policy change takes effect immediately.”
Now you have to select Disabled or Not Configured if you want to disable Publishing of User Activities or Enabled to Enable Publishing of User Activities depending on your preferences.
Next, click OK and exit the Group Policy Editor and then restart your computer to successfully apply the changes made.
