How to Fix Error 0x00000643

Among other things and innovations, Windows 11 brings to the table is the game mode. The game mode is a system designed to release some resources and optimize your system when Windows 11 detects that you are playing games. It also turns off automatic updates while the game is active. The game mode is active at all times and usually, everything works great but in some instances, it can sadly cause some performance issues. If you are one of these unlucky people where game mode is not working as supposed to do, don’t panic, we have a quick guide for you on how to turn it off.

1. Press ⊞ WINDOWS + I to open settings
2. Inside click on Gaming
3. Select Game mode
4. Click switch beside Game mode to turn it off
5. Close settings

Everything will be automatically saved and applied and you should not have any issues from now on. If for any reason you wish to turn game mode back ON, just follow the same steps and turn the switch to ON.

There is a central location in Windows 10 that allows users to view all the notifications from its Action Center. Aside from viewing notifications, users can also manage them and take necessary actions in just one single place. Notifications in Windows 10 look similar to a message icon but can be at variance in function. However, recently, a number of users reported that even though they receive notifications about new actions but when opening them, they see nothing. In other words, the notification is false, and to fix this, read on as this post will provide you a couple of workarounds. The Windows 10 Notifications and Action Center notification messages might show a mismatch. For instance, Windows 10 may say that you have some notifications but when you open Action Center, you find it empty and there are actually no notifications there. Take the case of the following screenshot, the Windows 10 Notification says that there are 6 new notifications available for viewing but the Action Center says otherwise. Before you troubleshoot the problem, you might want to run System Restore especially if you’ve made some changes in your computer prior to this issue which might have messed with the Windows 10 Notifications and Action Center. To perform System Restore, refer to these steps:

• First, press 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.

If the problem wasn’t fixed and you’re still getting false notifications, you might want to troubleshoot the problem further using the options given below.

Option 1 – via Windows PowerShell

• In the Start search, type “PowerShell” in the field and hit Enter to pull up the Windows PowerShell window.
• Next, copy and paste this command and hit Enter to execute it: Get-AppxPackage | % { Add-AppxPackage -DisableDevelopmentMode -Register “$($_.InstallLocation)AppxManifest.xml” -verbose }
• After that, reboot your computer and check if the false notifications are now gone.

Option 2 – Try renaming the Usrclass.dat file

DAT errors like the ones that are associated with the Usrclass.dat file, most likely occur during computer startup, program startup, or while you try to use a specific function in your program. Even so, it can easily be fixed. How? Refer to the given steps below.

• Tap the Win + R keys to open the Run dialog box.
• Then type %localappdata%MicrosoftWindows and hit Enter to get to the location of the UsrClass.dat file.
• After that, look for a file named UsrClass.dat and once you’ve found it, right-click on it and select the Rename option.
• Now rename the file to UsrClass.old.dat and then restart your computer and see if the problem is now fixed or not.

Hello everyone, I hope you are all doing well. Today we will be changing the Windows Lock Screen background. Changing the lock screen background is a very easy task and it can be done in a very short time. So let's jump right into it. The first thing you need to do is to press the Windows start button on the bottom left and then press settings. Once the settings screen appears, choose and click on Personalization. Inside personalization, click on the Lock Screen tab. On the right screen, under the picture, you will find Windows spotlight, click on it to bring a drop-down menu up. Your choice is presented as a single picture for background or slideshow, a series of pictures that are going to be looped in a given time interval. If you would like just a single picture for your background, choose that and click on it. Once you are in choose picture dialog, click on the browse button and navigate to the picture on your storage which you would like to have as a background. If however, you fancy slideshow as your lock screen background, click on the background drop-down menu and choose the slideshow. Next, click on add a folder and navigate to a folder where you have pictures that you would like to have as a slideshow for your Windows lock screen.

As you know, Windows 10 is equipped with a Mobile Hotspot feature that allows users to share the existing internet connections to other devices over Wi-Fi. However, one of the downsides to this feature is that it does not stay on if there are no devices connected to it for over five minutes. In other words, if there are no devices connected to the mobile hotspot for five minutes, it will turn off automatically. Thus, if you want the mobile hotspot to stay turned on, then you’ve come to the right place as this post will walk you through how to stop the Mobile Hotspot from turning off in Windows 10. There are two scenarios tackled in this post wherein the Mobile Hotspot feature turns off automatically and where the hotspot disables when there is no internet connection. To remedy these scenarios, you can try turning off the power saving feature or use a PowerShell command to change the “PeerlessTimeoutEnabled” settings or increase the Mobile Hotspot idle timeout settings. You could also increase the timeout period when a cellular connection is not available or disable the Wi-Fi and network adapter power management options. For detailed instructions, refer to each one of the given options below.

Option 1 – Try turning off the power saving feature

The first solution you can check out is to turn off the power-saving feature. To do so, follow these steps:

• Open the Settings app and go to Network & Internet and from there, click on the Mobile Hotspot option.
• Next, toggle the “Share my Internet connection with other devices” option.
• After that, toggle the “When no devices are connected, automatically turn off mobile hotspot” option.

Option 2 – Execute a command in PowerShell

The next option you can try to keep the mobile hotspot turned on is through a command in PowerShell. To get started, follow these steps:

• Tap the Win + X keys and select the “Windows PowerShell (Admin)” option.
• Next, execute the following command to make sure that the Mobile Hotspot stays on even when no devices are connected to it:

powershell -windowstyle hidden -command "Start-Process cmd -ArgumentList '/s,/c,net stop "icssvc" & REG ADD "HKLMSYSTEMCurrentControlSetServicesicssvcSettings" /V PeerlessTimeoutEnabled /T REG_DWORD /D 0 /F & net start "icssvc"' -Verb runAs"

• After the command is executed, here is what the script is doing in the background:
  • It stops the Mobile Hotspot service (icssvc).
  • It navigates to this registry path (HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesicssvcSettings) and creates a DWORD key named “PeerlessTimeoutEnabled” which has a value of 0.

• It then restarts the Mobile Hotspot Service (icssvc).

Option 3 – Try increasing the Mobile Hotspot idle timeout settings

Another option you can try is to increase the idle timeout settings of the mobile hotspot. In case you don’t know, the default timeout when there’s no active connection is about five minutes. So if you don’t want to keep it on always but want to keep it on longer than five minutes, then this option is for you. All you have to do is change the same key (PeerlessTimeout) as mentioned above, at a different location. In fact, you can change it to a maximum of 120 minutes. To give this a try, follow these steps:

• Tap the Win + R keys to open the Run dialog box and type “Regedit” in the field and then tap Enter to open the Registry Editor.
• Next, navigate to this registry path: HKLMSystemControlSet001ServicesICSSVCSettingsPeerlessTimeout
• From there, change its value to anywhere between 1 up to 120.
• Once done, exit the Registry Editor and restart your computer.

Option 4 – Try increasing the timeout period when a cellular connection is not available

There are many times when you want to connect devices so it becomes part of the network. And as pointed out, the Mobile Hotspot turns off automatically when there is no internet or mobile data but when you use a registry setting, you can change any value between 1 and 60 inclusive.

• Tap the Win + R keys to open the Run dialog box and type “Regedit” in the field and then tap Enter to open the Registry Editor.
• Next, navigate to this registry path: HKLMSystemControlSet001ServicesICSSVCSettingsPublicConnectionTimeout
• From there, set the value of the “Timeout” key between 1 and 60.
• After that, close the Registry Editor and restart your PC.

Option 5 – Try to disable the Wi-Fi and Network adapter in Power Management options

As you know, the Wi-Fi adapter and the network devices have properties that will turn off when on battery and when it’s not used for a long time so you can try to disable these options.

• Tap the Win + X + M keys to open the Device Manager.
• Next, expand the list of Network devices and select the Wi-Fi adapter.
• After that, go to the Power Management tab and make sure that anything related to power saving should be turned off. This will ensure that none of the network devices will turn off the Mobile Hotspot or trigger anything that will do that.

PC Optimizer Pro is a PC optimizer utility developed by Xportsoft Technologies. It is classified as a potentially unwanted program, due to its aggressive scan and registration reminders, and that it is often distributed bundled with other programs in a manner that leads many users to not know how it got on their computer. While not inherently malicious, PC Optimizer Pro adds numerous registry keys, startup entries and while running consumes a relatively high amount of system resources, especially during its scans. The software installs from a .exe file that is around 5.20 MB or 5.453.240 Bytes (depending on the version). As of the publication of these videos, the current version of PC Optimizer Pro was detected as malicious or potentially unwanted by at least 21 AntiViruses.

About Potentially Unwanted Applications

If you have ever installed freeware or shareware, chances are high that your computer can get installed with a bunch of unwanted applications. A Potentially Unwanted Program, also called PUP, in short, is actually software that contains adware, installs toolbars, or has other hidden goals. These kinds of programs are almost always bundled up with free software which you download from the net or are also bundled within the custom installers on many download sites. PUPs did not really constitute pure “malware” in the strict sense of the term. Just like malicious software, PUPs cause problems when downloaded and installed on your PC, but what makes a PUP different is that you give consent to download it – although the truth is vastly different – the software installation package actually tricks you into accepting the installation. Irrespective of whether it is regarded as malware or not, PUPs are nearly always harmful to the user as they might bring on adware, spyware, keystroke logging, and also other bad crapware features on your computer.

What do PUPs do on your computer, exactly?

Potentially Unwanted Programs come in many forms and varieties, but in most instances, these are adware programs that show annoying pop-up adverts and advertisements on websites you check out. The PUPs also get installed into your computer in the form of web browser add-ons and toolbars. Not only they needlessly take up space on your computer screen, but toolbars may also manipulate search engine results, watch your web browsing activities, decrease your web browser’s efficiency, and decelerate your internet connection to a crawl. Potentially Unwanted Programs at times act quite similarly to viruses or spyware. Some PUPs include keyloggers, dialers, along with other software to gather your private details that may result in identity theft. These are programs that don’t do anything good for you; in addition to taking over space on your hard drive, they also slow down your computer, often modify settings without your approval, the list of bothersome features goes on.

Ways to avoid PUPs

• Always study the EULA and privacy statement. Don’t agree until you know precisely what you are acknowledging. • Choose the “custom” install whenever installing a software program. In particular, look closely at those small boxes that have been checked as default, where you may ‘agree’ to receive promotions or install software bundlers. • Use good antivirus software, like Safebytes Anti-Malware that offers real-time protection against PUPs. • Avoid adding a freeware program you do not use. Turn off or remove toolbars and web browser extensions you don’t really need. • Always download software from reliable sources like official sites as opposed to untrustworthy sharing space. Avoid file-hosting sites where/when possible.

What you can do if Malware Prevents You From Downloading Or Installing Antivirus?

Practically all malware is bad, but certain types of malware do much more damage to your computer than others. Certain malware goes to great lengths to stop you from downloading or installing anything on your personal computer, particularly antivirus applications. If you are reading this right now, you have probably recognized that a malware infection is the real cause of your blocked web connectivity. So what to do if you need to install an antivirus program like Safebytes? There are a few steps you can take to circumvent this problem.

Install in Safe Mode

The Windows OS has a special mode known as “Safe Mode” in which just the bare minimum required programs and services are loaded. In the event the malware is blocking the internet connection and affecting the computer, running it in Safe Mode will let you download antivirus and run a diagnostic scan while limiting possible damage. To start the computer into Safe Mode, press the “F8” key on your keyboard right before the Windows boot screen comes up; Or right after normal Windows boot up, run MSConfig, look over “Safe Boot” under Boot tab, and click Apply. After you reboot into Safe Mode with Networking, you can download, install, and update anti-malware software from there. Right after installation, run the malware scanner to remove standard infections.

Switch to an alternate browser

Some malware may target vulnerabilities of a specific browser that block the downloading process. If you seem to have malware attached to Internet Explorer, then switch over to an alternate web browser with built-in safety features, such as Firefox or Chrome, to download your favorite antivirus program – Safebytes.

Install and run anti-virus from the USB drive

Another solution is to create a portable anti-malware program on your USB stick. Adopt these measures to employ a thumb drive to clean your infected computer system. 1) Download Safebytes Anti-Malware or MS Windows Defender Offline onto a clean PC. 2) Plug the Thumb drive into the clean computer. 3) Run the setup program by double-clicking the executable file of the downloaded software, with a .exe file format. 4) Choose the flash drive as the location for saving the file. Do as instructed on the screen to complete the installation process. 5) Now, plug the pen drive into the corrupted computer. 6) Double-click the anti-malware software EXE file on the USB flash drive. 7) Press the “Scan” button to run a full system scan and remove viruses automatically.

In addition, some malware is capable of replicating or preventing deletion. Doing this in Safe Mode is advised.

The following files, folders, and registry entries are created or modified by PCOptimizerPro

DLL files, also known as Dynamic Link Libraries are external parts of applications that run on Windows as well as other operating systems. Almost all applications are not complete in themselves and store code in different files. In this post, we will be discussing one DLL file called ntdll.dll. It is described as “NT Layer DLL” which means that it contains some Kernel functions that help in the normal functioning of the Windows operating system. It is created by Windows in the System32 folder when the OS gets installed. This file can serve different programs simultaneously by providing them with different Kernel functions which support the programs’ performance. However, if you encounter the ntdll.dll file error on your Windows 10 computer, read on as this post will guide you in fixing the problem.

Option 1 – Try to re-register the ntdll.dll file

You may have to re-register the ntdll.dll file using the regsvr32.exe before you can successfully install the program and fix ntdll.dll file crash error. The Regsvr32 tool is a command-line utility that can be used to register and un-register the OLE controls like DLL and ActiveX (OCX) control in the Windows operating system. Follow the steps below to use it.

• Open Command Prompt as admin from the WinX menu.
• Next, type the following commands in the elevated Command Prompt and hit Enter to execute the command. This will re-register the affected DLL file using the Windows operating system tool, regsvr32.exe.
  • exe /u ntdll.dll
  • exe ntdll.dll
• You should see a message saying, “DllRegisterServer in vbscript.dll succeeded” if the Regsvr32 tool was able to run successfully. After that, try to install the program again and see if it now works.

Option 2 – Disable problematic Internet Explorer add-ons

There are instances when some add-ons in the Internet Explorer browser can cause the ntdll.dll file crash error. Thus, you need to disable some add-ons in Internet Explorer and then check if it fixes the problem.

Option 3 – Try running the DISM tool

You might want to repair potentially corrupted files in your system as having them could also trigger the ntdll.dll file crash error. To repair these corrupted system files, you can run the DISM commands:

• Tap the Win + X keys and click on the “Command Prompt (Admin)” option.
• After that, input each one of the commands listed below sequentially to execute them:
  • Dism /Online /Cleanup-Image /CheckHealth
  • Dism /Online /Cleanup-Image /ScanHealth

One of the important processes in the Windows operating system is the Setting Synchronization or SettingSyncHost.exe. This process is the one responsible for synchronizing the settings of your computer with other devices. It is the one that replicates settings like OneDrive, Internet Explorer, wallpapers, and so on, to other systems. However, it has been known to cause high CPU usage in Windows 10 and there are times when it causes the system to freeze or system lags. So if you notice that the SettingSyncHost.exe process is causing high CPU usage in your computer, worry not for this post will guide you in fixing them. You have to be cautious when you notice high CPU usages caused by system processes since cybercriminals mostly set the names of viruses in a way that the system or the user won’t be able to identify them. Cyber crooks could name the virus and malware the same as one of the system processes like SettingSyncHost.exe to make it seem like it’s a legitimate process. Thus, you need to keep in mind that original system processes like the SettingSyncHost.exe file are located in the System32 folder. The original SettingSyncHost.exe file is located in the System32 folder. To check for the same, right-click on the troublesome process in the Task Manager and select Open file location. If the place is any other than the System32 folder, run a full system anti-virus scan on the system. The SettingSyncHost.exe causes high CPU usage when it gets stuck in the sync process and is not able to come out of the loop. To fix this problem, you need to follow the solutions offered below but before you proceed, make sure that you create a System Restore point first.

Option 1 – Apply some registry tweak

The first thing you can do is to apply some tweaks to the Windows Registry. To get started, follow these steps:

• Tap the Win + R keys to open the Run utility and type “Regedit” in the field and then tap Enter to open the Registry Editor.

• From there, right-click on the key and select Permissions.
• After that, check the box next to “Allow” for Full Permission for every user group.
• Now click on the Apply and OK buttons to save the changes made.
• Then restart your computer.

Option 2 – Close the Host process for setting synchronization

If the registry tweak didn’t work, you can try to close the host process for setting synchronization, especially if this process continues to hog resources. You can terminate this process by opening the Task Manager. From there, end the process or task of the host process. On the other hand, you can also turn off the Host process for synchronization by opening Settings > Accounts > Sync settings located in the left pane. After that, turn off the Sync setting.

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 3 – 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 dependent 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 4 – 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 5 – Try running 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 your screen is stuck at “Checking for updates”. 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.

• Restart your computer.
