If you encounter Error Code 0x80090016 while trying to create a PIN or when you are using Microsoft Store, then you’ve come to the right place as this post will guide you in how you can fix this problem.
Recently some users reported that they were unable to sign in or set up the Windows 10 Login PIN. Note that the potential fixes for this issue are totally different in both scenarios.
Here’s the error message you get when you encounter the PIN related error:
“Something went wrong, We weren’t able to set up your PIN. Sometimes it helps to try again or you can skip for now and do this later.”
On the other hand, here’s the error message you get for the Microsoft Store-related error:
“Try that again, Something happened on our end and we couldn’t sign you in.”
Here are some potential fixes you can try to fix the Error Code 0x80090016 in the Microsoft Store:
Option 1 – Try to sync the Date and Time
The first thing you can try is to sync the Date and Time of your computer as the wrong Date and Time settings are one of the most common causes of connection problems like the Error Code 0x80090016. This is because of the incompatibility between the SSL Certificate validation date and the System Clock. Thus, you have to sync your System Clock. Refer to the steps below to do so.
Start by tapping the Win + I keys to open the Windows Settings.
Next, go to Time & Language > Date & time.
From there, turn the toggle on for the “Set time automatically and Set time zone automatically” option on the right-side panel.
After that, click on Region & language located on the left side panel and make sure that the Country or region on the right-side panel is set to the country you live in.
Now close the Settings app and restart your computer and see if it fixes the problem or not.
Option 2 – Try to re-register the Microsoft Store app via PowerShell
Tap the Win + X key combination or right-click on the Start button and click on the Windows PowerShell (Admin) option.
If a User Account Control or UAC prompt appears, just click on Yes to proceed and open the Windows PowerShell window.
Next, type in or copy-paste the following command to re-register the Microsoft Store app and tap Enter:
Wait for the process to be completed and then restart your computer.
Option 3 – Try to reset the Microsoft Store cache
Just like browsers, Microsoft Store also caches as you view apps and games so it is most likely that the cache is no longer valid and must be removed. To do so, follow the steps below.
Right-click on the start button and click on Command Prompt (administrator).
Next, type in the command, “exe” and tap Enter. Once you do, the command will clear the cache for the Windows Store app.
Now restart your PC and afterward, try opening Microsoft Store again and then see if Error Code 0x80090016 is resolved or not.
Option 4 – Try to run the Windows Store Troubleshooter
The Windows 10 Store Apps Troubleshooter will help you in fixing the Error Code 0x80090016. This is a great built-in tool from Microsoft that helps users fix any app installation issues. So this is worth a try to solve the problem. This built-in tool also helps you fix the Windows 10 Store if it isn’t working.
To use the Windows Store Troubleshooter, follow the steps below.
Tap Win + I keys again to open the Windows Settings panel.
Go to Update & Security and then go to Troubleshoot.
On your right-hand side, scroll down to find the Windows Store Apps and then click on Run the troubleshooter option and see if it fixes the problem.
On the other hand, you can use the options below if you encounter Error Code 0x80090016 while setting up your PIN.
Option 5 – Try to manage the NGC Folder
You need to boot your computer into Safe Mode first.
Next, delete all the contents of the NGC folder and you can do that by taking ownership of the folder first. To do so, refer to these sub-steps:
First, locate the concerned folder and right-click on it then select Properties.
Next, click on the Edit button in the Properties window and click OK to confirm if you got a User Account Control elevation request.
After that, select user/group from the permission windows or click on the Add button to add another user or group. It would be best if you add “Everyone” to give permission.
Then check “Full Control” under the “Allow” column to assign full access rights control permissions.
Now edit the permission to Full Control for “Everyone”.
Click OK to save the changes made and then exit.
After you take ownership of the folder, you can now delete all of its contents.
Once you’re done, restart your computer and see if the problem is fixed.
Option 6 – Try to use the Group Policy Editor
Tap the Win + R keys to open the Run dialog box
Then type “gpedit.msc” in the field and hit Enter or click OK to open the Group Policy Editor.
Next, navigate to this setting: Computer Configuration > Administrative Templates > System > Logon
After that, double click on “Turn on convenience PIN Sign-in” and set its radio button to Enable. This policy setting has the following description:
“This policy setting allows you to control whether a domain user can sign in using a convenience PIN. If you enable this policy setting, a domain user can set up and sign in with a convenience PIN. If you disable or don’t configure this policy setting, a domain user can’t set up and use a convenience PIN. Note: The user’s domain password will be cached in the system vault when using this feature. To configure Windows Hello for Business, use the Administrative Template policies under Windows Hello for Business.”
After you set the radio button to Enable, it will turn on the Logins using the PIN. Note that setting the radio button to Disabled or Not Configured will turn off the Logins using the PIN.
Now exit the Group Policy Editor and restart your PC so that the changes can take effect.
It is common to run multiple programs and applications at the same time and it’s important to be able to switch between them using their Taskbar icons or using the usual Alt + Tab shortcut. However, there are times when you might suddenly find that neither of the aforementioned methods worked and you will no longer be able to switch between programs in the Windows Taskbar. To fix this issue, refer to the options given in this post.
For instance, when you have multiple instances of Microsoft Edge running and every time you press the Alt + Tab combo nothing happens so you are left with no choice but to minimize everything and then hover your mouse on the icon and switch between the instances of Edge. You will also notice that the right-click on the taskbar won’t respond back and will only keep on showing the loading circle icon.
Here are a few tips you can follow to fix the issue with the Windows 10 Taskbar.
Option 1 – Try to restart the Windows Explorer
This is one of the basic things you can try as restarting Windows Explorer helps in refreshing the user interface and makes most of the things work in relation to the user interface.
To get started, tap the Alt + Ctrl + Del keys to pull up the Windows Task Manager.
After opening Task Manager, look for “explorer.exe” under the list of programs.
Once you find the explorer.exe, right-click on it and click Restart.
Option 2 – Try changing the Foreground Lock Time
Aside from restarting Windows Explorer, you could also try changing the Foreground Lock Time to fix the issue with the Taskbar.
Tap the Win + R keys to open the Run dialog box.
Then type in regedit in the field and tap Enter to open the Registry Editor.
Next, go to this registry key – HKEY_CURRENT_USERControl PanelDesktop
Next, change the ForegroundLockTimeout value from200000 to 0. After that, it will make sure that no other application will take away the focus from your current program or application. It could be that some other application has taken away the focus and even when you try to actually switch, the focus gets back to the old one. Anyhow, since you already changed the value of ForegroundLockTimeout, it will ensure that the focus is not switched.
Note: If you are running some Full-Screen applications there are some devices especially the gaming ones, disable the Windows key to make sure that you won’t be able to switch. If this is the case, you need to make some modifications to the Full-Screen games.
If you suddenly encounter Error 0x80000003 while trying to execute a random file then read on as this post will show you how you can fix such an error. Obviously, it mostly happens on executable files or .exe files and is most likely caused by the conflict in the execution of some registry files or it could also be caused by missing drivers or it could also be due to some incompatible hardware which is why you’re unable to run the executable file.
When you encounter this error, you will see the following error message on your screen:
“The exception Breakpoint, A breakpoint has been reached, (0x80000003) occurred in the application.”
As you can tell, the Windows Executive STATUS message is a warning and if you are given an option, you must select one of the options from the message box. So if you are running the application in an end-user environment rather than in a development environment, you must contact the supplier of the running application regarding this error message since this shouldn’t be happening when a finished program is running.
Before you get started executing the troubleshooting guide given below, make sure that you create a System Restore Point first since you will be dealing with some critical settings in Windows. Having done this, proceed to the options provided below.
Option 1 – Try to run the CHKDSK utility
Running the CHKDSK utility might also help you resolve Error 0x80000003. 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 following command and hit Enter:
chkdsk /f /r
Wait for the process to be completed and then restart your computer.
Option 2 – Try to run a System File Checker scan
You can also try to run a System File Checker or SFC scan in order to scan your computer for corrupted files that might be the cause behind the Error 0x80000003. Once it finds any corrupted system files, it will automatically fix them. To run System File Checker, here’s what you have to do:
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.
Restart your computer after the scan is completed.
Option 3 – Perform a Clean Boot
There are some instances that some conflicting programs installed in your computer might be the one that’s causing the Error 0x80000003 to appear. 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 4 – Run the Memory Diagnostic Tool to check for Memory leaks
Tap the Win + R keys to open Run and type mdsched.exe and hit Enter to open the Windows Memory Diagnostic Tool.
After that, it will give two options such as:
Restart now and check for problems (Recommended)
Check for problems the next time I start my computer
Once your computer has restarted, perform a basic scan or you could also go for the “Advanced” options such as “Test mix” or “Pass count”. Simply tap the F10 key to start the test.
Option 5 – Try contacting the developer
If you find that you’re getting Error 0x80000003 on only one particular application, then you can try to contact the developer of the software that’s throwing up this error. All you have to do is search the web for the official support channel of the software and discuss the error from there.

The speed at which the CPU runs varies depending on any Windows laptop or desktop. And in case you don’t know, the CPU does not run at full speed all the time as it depends on how the operating system distributes the load so it works accordingly. However, there are instances when it runs at full speed especially if your Windows 10 computer is on a heavy workload. But if you find that even when your computer is already on a heavy workload and the CPU is still not running at full speed, then you need to look into this situation. To verify that your CPU’s speed, you can use any CPU stress test tool.
This kind of issue is common on laptops compared to desktop computers since laptop runs on battery. The Intel Processor on laptops uses the Speed Stepping Technology which means that when you are doing some small tasks on your laptop, the processor’s speed is reduced. On the other hand, if this happens when you are using a heavy application, it can be due to a low charge on the laptop’s battery. Thus, Windows will try its best to keep the computer running for as long as possible by reducing the CPU speed or processor. But there are times when you are ready to sacrifice battery to make sure that the work gets done on time. To achieve that, here are some options you can check out.
Option 1 – Try setting the processor state to the maximum in Power Options
Type “control” in the search box to view the classic Control Panel as well as the popular options.
Next, click on Power Options > Change plan settings > Change advanced power settings.
Then navigate to Processor power management > Maximum processor state.
Now select 100% when it is on Battery and Plugged in.
After that, expand the System cooling policy option and make sure to set it as Active to make sure that the battery won’t overheat.
Finally, apply the changes made to all the profiles of the power management and restart your computer. This will ensure that your CPU will run at maximum power at all times.
Option 2 – Try to update or disable the Intel Power Management driver
The next option you can try is to update or disable the Intel Power Management driver. The Intel-powered computers have dedicated software that controls CPU speed and Fan speed when it needs to save battery. You can try disabling it temporarily and check if there are any changes with the CPU fan speed.
First, restart your computer by holding the Shift key to boot your computer into Troubleshooting or Advanced mode.
Next, go to Troubleshoot > Advanced Options > Command Prompt.
Then change the directory to C:/Windows/System32/driver and then rename the file named “Intelppm” by entering the “ren intelppm.sys intelppm.sys.bak”.
Now restart your computer.
Note: If you were not able to find the drivers in C:/Windows/System32/driver, check if they are available under C:/Drivers/IntelPPM. After that, the CPU speed should change now with the Intel driver missing from the system. And in case you want to enable it, simply follow the same steps given above and rename the file again.
Option 3 – Try disabling the IPPM using the Command Line or Registry Editor
Command Prompt:
Tap the Win + R keys to open the Run dialog box and type “cmd” and tap Enter to open Command Prompt.
Next, type this command and hit Enter: sc config intelppm start= disabled
The “sc config” command you entered modifies the value of a service’s entries in the registry as well as in the Service Control Manager database.
Registry Editor:
Tap the Win + R keys to open the Run dialog box and type “Regedit” in the field and hit Enter to open the Registry Editor.
Next, navigate to HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesintelppm.
From there, double click on the intelppm and change the Start key value to
Now close the Registry Editor and reboot your computer.
Note: The steps given will make sure that the CPU will run at maximum power at all times.
Running the Windows Update service does not always go well as from time to time, you could encounter some errors when using it. One of these errors is the Windows Update Error 0xc1900403. In such cases, you will see the following error message under the Windows Update section:
“There were problems installing some updates, but we’ll try again later, If you keep seeing this and want to search the web or contact support for information, this may help – 0xc1900403”
The log files displayed in the error message may include, “0XC1900403 – MOSETUP_E_UA_CORRUPT_PAYLOAD_FILES”. This indicates that the payload files are corrupted which is why you’re getting the Windows Update Error 0xc1900403 and to fix it, you can try to restart your computer and install the updates again or reset the Windows Update-related folders. You could also run the Windows Update troubleshooter or use either the Standalone Installer or the Media Creation tool. For more details, refer to each one of the options provided below.
Option 1 – Restart your computer and try installing the Updates again
Restarting your computer can also help in fixing the Windows Update failed to install error 0x80240034. There are cases where the issue resolves on its own as it could just be some simple network or PC error.
Option 2 – Delete the contents in the Software Distribution folder and Catroot2 folder
Open the WinX Menu.
From there, open Command Prompt as admin.
Then type in the following command – don’t forget to hit Enter right after typing each one of them.
net stop wuauservnet start cryptSvcnet start bitsnet start msiserver
After entering these commands, it will stop the Windows Update Service, Background Intelligent Transfer Service (BITS), Cryptographic, and the MSI Installer
Next, go to the C:/Windows/SoftwareDistribution folder and get rid of all the folders and files thereby tapping the Ctrl + A keys to select them all and then click on Delete. Note that if the files are in use, you won’t be able to delete them.
After resetting the SoftwareDistribution folder, you need to reset the Catroot2 folder to restart the services you just stopped. To do that, follow these steps:
Type each one of the following commands.
net start wuauservnet start cryptSvcnet start bitsnet start msiserver
After that, exit Command Prompt and restart your computer, and then try to run Windows Update once more.
Option 3 – Try running the Windows Update troubleshooter
You might also want to run the Windows Update Troubleshooter as it could also help in fixing Windows Update Error 0xc1900403. 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 4 – Try to use the Media Creation tool
The Media Creation tool in Windows allows you to use the ISO installation file to make a bootable device that you can use to install Windows on your PC. Note that this is kind of different from the usual installation process as it could erase your computer’s current settings and data on the primary drive. Thus, before you proceed, you need to backup all your data into some removable drive and then use the Media Creation Tool to make a bootable drive.
After making the bootable drive, you need to plug it into your computer and then reboot.
Next, tap the F10 or Esc key to open the boot options.
Now set the boot priority of the removable drive the highest. Once the setup comes forth, follow the next onscreen instructions and install Windows without any problems.
The Disk Management tool in Windows 10 is a built-in tool that contains a user interface used to manage disk partitions to administrators of the computer. There are lots of instances when you have to change the size of the hard disk partition or reduce the size and so on. This is where the Disk Management tool comes in. It’s useful as the command line interface can be quite confusing and risky for some users. However, there are cases when this tool stops working. A proof of this the reports submitted recently by some Windows 10 users. Based on the reports, the Disk Management does not load or respond. If you are having the same problem, read on as this post will give you some suggestions on what you can do to resolve the problem.
Option 1 – Try restarting the Disk Management Service
Tap the Win + R key combination to open the Run dialog box.
Then type “services.msc” in the field and hit Enter or click OK to open the Windows Services Manager.
Next, scroll down in the service list until you see the Virtual Disk Service. Double click on it to open and then select Automatic.
Click on Apply and OK to save the changes made.
If it hasn’t started yet, you can just click on the Start button to start the Service. The Virtual Disk service provides management services for disk, volumes, file systems as well as storage arrays.
Now save all the changes you’ve made and restart your computer. Then check if you can now use the Disk Management tool without any problem.
Option 2 – Try using the System File Checker scan
System File Checker or SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files with good system files that might be causing some issues with the Disk Management tool. To run the SFC command, follow the steps given below.
Boot your PC into Safe Mode.
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 – Try using the DISM tool
Aside from the System File Checker, the DISM tool can also help you resolve the issue with the Disk Management tool. It helps in restoring the health of your computer.
Open the Command Prompt as admin.
Then type in this command: Dism /Online /Cleanup-Image /RestoreHealth
Do not close the window if the process takes a while as it will probably take a few minutes to finish.
Option 4 – Try using Diskpart and Fsutil
If both the System File Checker and DISM tool didn’t work, you can use command-line tools like diskpart and fsutil. These command-line tools are powerful but you need to be careful especially if you’re not that familiar with using them. However, it’s recommended that you have somebody who knows if you’re really inexperienced with this kind of stuff.
I do not know about you, but I prefer to set my Windows to be more to my liking and not how Microsoft thinks it should be. Let’s face it, not all users feel comfortable whit Microsoft settings and idea how things should be.
One of the things I particularly did not like even in Windows 10 is icons that come by default on my taskbar, now so far, well until the latest Windows 11 update you could remove default taskbar icons the same way as in Windows 10, just right-click on them and unpin, sadly with latest update build on Windows 11 this option has been removed.
In order to remove default icons from the taskbar, one must go now to Windows 11 settings and choose from there which one you would like to be placed on it. Of course, this is nothing game-breaking but it still feels strange why the standard option has been removed, it just makes no sense but lately not many things that come from Microsoft do.

We have all experienced Windows errors over time and that can range from simple ones that will do very little to no harm and can be even system breaking making us lose our work or completely making the PC unusable. No one likes them but they happen, and usually, they happen once we least expect them.
No matter how frequent and unpleasant they might be there are ways to keep them at the minimum and even avoid them.
We will discuss steps that you can take in order to do this, simple tips and guides on how to keep your computer in top form and eliminate not just Windows, but any kind of errors altogether.
Keep your hardware clean
Believe it or not, some serious Windows errors like the dreaded blue screen of death can come from hardware issues not from the software at all. It is very important to keep your computer clean and with enough air flow so it can function properly.
Keeping applications on the drive might seem harmless but sadly that is not the case. Some applications have a certain impact on the system itself after all most of them are tweaking registry entries in Windows and sometimes having too many applications means an increased possibility of conflict over certain resources even when they are not running.
Some applications like adobe creative suite, for example, will have certain services always running in the background, and more of these kinds of applications you have, more services, more places for unexpected errors when they collide. Some of them will also install certain dependencies that could be problematic.
The general idea is: if you are not using it, uninstall it and you will be safer and more resilient to errors inside OS.
Do not use pirated or cracked software
Besides moral and law implications that using pirated or cracked software might bring you there are also certain other things that might be problematic. Certain "free" software might come packet with some problematic malware, for example, it is not uncommon for attackers to use some popular software to pack their malicious application with it.
Other things might be wrong and incomplete tweaking with application in order to bypass security and thus bringing some instability due to scripts needed to run in order to achieve this goal.
Keep your drivers updated
Errors can also come from old drivers or bad drivers, device manufacturers are not all-knowing and perfect, and sometimes drivers can wreak havoc on the system. Having updated drivers can minimize any kind of unexpected behaviors inside the operating system making it more stable and reliable.
You can check your driver version in the control panel inside the Windows OS and then compare it to the ones found on the manufacturer's site, if there are newer available it is recommended to download and install them,
Keep software updated
Applications can have bugs, and bugs can lead to certain errors both in the system and when using the app as well. It is in your best interest to get the latest patch or newer version of the software in order to avoid these unpleasant experiences.
Also, certain codecs and extensions that are installed directly in Windows can also have some unpredictable behavior, updating is the best solution to keep them in line.
Keep Windows updated
Same as with drivers and applications, Windows itself is not immune from bugs and some unpredictable issues. Luckily Microsoft is always working on fixes and features of Windows but in order to actually have benefited from that work, you will need to keep Windows updated. Sometimes a bad update can introduce some errors but you can always roll back to the previous and wait for them to fix everything and then download them all.
Check the health of your hardware regularly
Hardware components have their life cycle, more quality ones tend to last longer but eventually, they will reach the end of their lifecycle. There are a lot of testers for various components in your computer that can check different things and provide you with information about the state of your components.
If you are on Windows 11, Microsoft has included a basic health app inside OS, just type PC health check in search and start the app. For some more detailed information and advanced checks, you will have to use a custom application. There are plenty of them specialized for single components like RAM, SSD, etc. A simple google search with providing you with top results and most of them are free for personal use.
Remember, a faulty component or component that is reaching its life cycle can produce many errors inside the operating system.
Windows defender error 0x800700AA, service can not be started comes when the user is trying to run Windows defender scan on their system.
This kind of behavior happens for two reasons mostly, third-party application conflict or corrupted system files.
In this article, we will tackle both scenarios and provide you with solutions in both cases.
Third-party application conflict
In this rare scenario when Windows defender can not start scan due to conflict with installed service or application in the system solution is quite simple. Restart your PC into safe mode and run the scan from there. In a safe mode environment, minimum drivers and services are only loaded eliminating any conflicts that might occur when everything is booted. If Windows defender can not run the scan in safe mode and you get the same 0x800700AA error then you can eliminate application conflict as a reason and move to the next solution which will tackle corrupted system files. If you, however, managed to run a scan then you have a rare third-party application conflict, you can boot normally into windows and try to eliminate one by one to see which one is causing the issue. The safest bet would be to start with security software because most of the time that is what causes conflicts in running services and applications.
Corrupted system files
If the previous solution has not provided you with results then you have system file corruption that needs to be fixed. Move from one solution to another as presented below:
Run SFC scan
SFC scan is a built-in Windows tool for solving corrupted system files issues, it is fully automated and does not require from the user any kind of knowledge or information. To run it and scan the system do the following:
Press ⊞ WINDOWS + X to open the secret menu
Left-click on the command prompt (admin)
In command prompt type SFC /SCANNOW and press ENTER
Wait for the process to finish, do not interrupt it and once it is done, restart your computer
Run DISM scan
DISM scan is similar to SFC scan but it tackles different types of system file corruption and it is recommended to run it also after SFC has been completed. Please note that for DISM scan to be successful you will need a stable internet connection since DISM will replace corrupted files with new ones downloaded from Microsoft. To run it do the following:
Press ⊞ WINDOWS + X to open the secret menu
Left-click on the command prompt (admin)
inside command prompt type: exe /online /cleanup-image /scanhealth followed by ENTER, then type: Dism.exe /online /cleanup-image /restorehealth also followed with ENTER.
Leave scan to finish and reboot your PC
I do not know about you, but I prefer to set my Windows to be more to my liking and not how Microsoft thinks it should be. Let’s face it, not all users feel comfortable whit Microsoft settings and idea how things should be.
One of the things I particularly did not like even in Windows 10 is icons that come by default on my taskbar, now so far, well until the latest Windows 11 update you could remove default taskbar icons the same way as in Windows 10, just right-click on them and unpin, sadly with latest update build on Windows 11 this option has been removed.
In order to remove default icons from the taskbar, one must go now to Windows 11 settings and choose from there which one you would like to be placed on it. Of course, this is nothing game-breaking but it still feels strange why the standard option has been removed, it just makes no sense but lately not many things that come from Microsoft do.
