Could not connect to the System Event explanation: Although logging into a Windows 10 computer may seem like a simple process, it’s actually not since the Windows operating system has built a mechanism in a way that any third party or malware intervention would not compromise access to the system. This mechanism is supported by numerous services, functions, and DLL files. And Microsoft has been taking this security to a whole new level with the introduction of Windows Hello. Recently, a number of users reported getting the “Windows could not connect to the System Event Notification Service service. Please consult your system administrator” error when logging into their computers. While some users also reported that although they can log in, they encounter the same error message from the Notification area. There are several options you can check out to resolve the error. You have to check the status of several Windows Services and make sure that they are running. You also have to reset Winsock as well as run the System File Checker scan.

Option 1 – Check for certain Windows Services

• First, you need to tap the Win + R keys on your keyboard to open the Run dialog box.
• Next, type “services.msc” in the field and click OK or tap Enter to open the Windows Services Manager.
• After that, you will see a list of services and from there, look for the following Windows Services:
  • DHCP Client
  • System Event Notification Service
  • Windows Font Cache Service
• Now make sure that the Startup Type of each service is started and running.

Option 2 – Try resetting the Winsock drivers

• In the Start Search, type “command prompt” and right-click on Command Prompt from the search results, and then select the “Run as administrator” option.
• After opening Command Prompt, execute this command: netsh winsock reset

Note: If you are using IPv4, execute the “netsh int ipv4 reset” instead. On the other hand, if you are using IPv6, execute the “netsh int ipv6 reset”

• Now exit Command Prompt and see if the error is now fixed.

Option 3 – Try running System File Checker or SFC scan

You could also run System File Checker or SFC scan to fix the BSOD error. It 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. 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.

There are various components that take part during a Windows Upgrade process such as the CPU, Disk, Network, and many more. This is why the process of upgrading your Windows 10 computer can be quite complex and due to its complexity, there are times when you might encounter some errors like the Windows Upgrade error 0x800701E3. If you encounter this kind of error then it has something to do with the “disk” part of the whole upgrade process which could be due to a conflict with the storage of your Windows 10 computer. When you receive this error, you will see the following error message on your screen:

“Windows cannot install required files. Make sure all files required for installation are available and restart the installation. Error code: 0x800701e3.”

To fix this Windows Upgrade error, here are some suggestions that might help.

Option 1 – Delete Files from Software Distribution Folder & Catroot2 folders

The downloaded Windows Updates are placed in a folder called “SoftwareDistribution”. The files downloaded in this folder are automatically deleted once the installation is completed. However, if the files are not clean up or if the installation is still pending, you can delete all the files in this folder after you pause the Windows Update service. For complete instructions, refer to the steps below.

• 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 wuauserv net start cryptSvc net start bits net start msiserver

The Local Security Authority Subsystem Service or LSASS.exe is a process in the Windows operating system that is valuable as it enforces the security policy on the computer. Every time you log in to the Windows Server, the LSASS.exe is the one that handles the password changes and creates the access tokens while updating the security log. However, it is also frequently targeted by malware and is often imitated. The original location of this file is at “C:/Windows/System32” so if you open the Task Manager and notice that a process with a similar name has a different location then it is definitely a threat and is exploiting the security of your computer. To resolve issues related to LSASS.exe, here are some fixes that could help.

Option 1 – Use the Performance Monitor’s Active Directory Data Collector

Note that this option will only work on the recent Windows server versions. Refer to the steps below to use the Performance Monitor’s Active Directory Data Collector set on your computer.

• Tap the WINKEY + R button to open the Run dialog box.
• Then type “Perfmon.msc” in the field and hit Enter to open the Performance Monitor and from there open the Server Manager.
• Next, navigate to Diagnostics > Reliability and Performance > Data Collector Sets > System from the left side of the navigation bar.
• Then right-click on “Active Directory Diagnostics” and select Start from the context menu.

The report will contain all the information as well as conclusions. However, it does not mean that it will also contain the exact cause of the problem with LSASS.exe. Nevertheless, it should help you in fixing the problem.

Option 2 – Try to 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 to good system files that might be the cause why the LSASS.exe file is having some issues. To run the SFC command, follow the steps given below.

• Type “cmd” in the Start search and then right-click on the appropriate search result.
• Next, select “Run as administrator” to open Command Prompt with admin privileges.
• 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.

 Now restart your computer and see if the problem is fixed or not.

Option 3 – Put your computer in a Clean Boot State

If none of the options given above helped, you can try putting your computer in a Clean Boot State as this can help you in finding any incompatible programs that’s causing the problem.

• 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”.

• 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.

Once you’ve found any incompatible programs, you need to uninstall them. Refer to the steps below to do so.

• 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.

Long working hours on a laptop can have some issues with laptop heating and thus slowing down. Today we will take a look at how can you prevent it from heating and keep it in a normal temperature range so it lasts longer and works better.

Close unnecessary programs or browser tabs

Usually, the main reason for high laptop temperature is the heavy and constant workload. Of course, the solution is very simple, turn off unnecessary browser tabs or applications running in the background, and less power will be needed for operation thus directly reducing workload and temperature.

Place it on a hard flat surface

Laptops generally have vents on the side and even under them, these vents, of course, are made so hot air is disposed of through them but if they are covered that will create issues. Placing computers on textiles, pillows, and legs can obstruct their venting holes and increase heat also since they are materials that are not taking heat away.

Your best practice should be placing the laptop onto a hard flat surface so air can flow freely and if you need to keep it in your lap there are lap desks made for this purpose.

Clean the laptop

With some good cleaning, the laptop can stop overheating, and generally, it will be cooler. Vents that has for ventilation can get clogged over large periods of time due to dust which is always present. Compressed air can be a quick easy solution to open the vents and redust it. Other methods include a compressor, vacuum, or brush in order to quickly remove any dust clogs. Taking it into service for complete redusting and paste change is also a great option.

Place it on the dedicated pad

There is some disagreement about using dedicated cooling pads for laptops, some say they are not effective at all, and some swear by them but from my experience good paired laptop and pad can indeed help with cooling it down. Usually, cooling pads will come with fans that will take away heat from the laptop itself reducing its overall heat.

Change your Windows power plan

If your laptop is constantly hot but you are not doing much with him check Windows power settings. There is a good chance it is set to run on a high-performance plan and if this is the case switch it back to a balanced power setting. Power plan like high performance will drain more power and more power will mean more heating. Of course, this will affect performance as well but for regular work that excludes some power gaming, video, and picture manipulations and other demanding tasks this power plan will work just fine.

Take control of the fans inside your laptop

Internal cooling is important and sometimes fans are not running to their full capacity so increasing their speed or changing their plan of work can cool down the computer nicely. Some laptops have fans controlling application already on them, especially gaming laptops but most of them do not. If your laptop does not have it, go to your laptop brand website and see if such an application exists for your model, if it does, download and install it but if there is no such application try general free ones like SpeedFan or Argus Monitor.

Reduce voltage of CPU and GPU

How more power means more heat, reducing the power that CPU and/or GPU take can be reduced inside BIOS by lowering voltage of these 2 components. First, go to BIOS and write down the voltage that is currently assigned to your CPU and/or GPU so you can bring it back if ever needed, also take note that reducing voltage and thus power will not affect negatively your components but increasing it thus overclocking can and will so be careful when bringing voltage back not to overdo it. You can always also reset your BIOS settings to bring them back to factory settings.

Do not use the laptop when charging it

When the laptop is placed on the charger in order to be charged and used at the same time, more power is drawn to it, and since the battery is taking electric charge instead of providing it more heat will be generated now since two different sources will be generating it, the battery itself and computer. When you really can not wait for the laptop to be charged, use it, but turn it off and wait to be fully charged if you can.

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.
