It has been reported that there are systems out there with Windows 11 operating systems that do not use the whole RAM memory installed in the system. If by any chance you are one of the unfortunate users that has encountered this issue, fear not, we have a solution for you.
Run the Windows Memory Diagnostic toolMemory Diagnostic tool is a built-in tool in Windows, it was designed to automatically find and repair memory issues and should be your first step toward resolving this issue.
If after reboot system still does not see and use whole available RAM, repeat this process and turn back ON paging. After you are done move to the next solution.
If the provided solution has not worked, uncheck the Maximum memory checkbox and save the changes. Move to the next solution.
In order to do this fix, you will need to enter BIOS on your system. How entering BIOS is different from system to system depending on your manufacturer, especially if it is a laptop this step you will have to do alone. Go to your motherboard manufacturer or laptop manufacturer and see how to enter BIOS.
Your BIOS might be different from ours and you might not have the System Agent Configuration option, in this case, go through the setting and try to locate Memory Remap Feature. If this feature is missing as well move to the next step.
Sometimes RAM memory cannot be slotted properly or just purely switching them in slots can solve the issue. Take RAM out, clean memory slots, clean motherboard connectors for them, and place them back in a different order.
If by any chance none of the methods worked, then the issue might be in the hardware itself, either memory banks themselves, motherboard, power supply, etc. If this is sadly the case, you will have to locate the issue and replace the faulty part.
If you are not technical enough for this adventure, the best solution is to take a PC to a computer repair shop.

chkdsk /f /r
taskkill /IM "processname" /T /F processname – it is the name of the process which you can see on the Details tab of the Windows Task Manager. /IM – it is the one that specifies the image name of the process, which follows, that is to be terminated. /T – it is the one that kills not just the main process but also the child process. /F – it is the one that terminates the process forcefully.
wmic process where name='processname.exe' deleteNote: In the given command, you need to replace “processname.exe” with the name of the particular process you want to terminate which is found in the Details tab of the Windows Task Manager.
kill -id pidNote: In the given command above, “pid” is the Process ID number of the process you want to terminate. And for you to identify this number, you need to open the Details tab of the Windows Task Manager once again and take note of the number against the process you want to get rid of. Alternatively, you can also run the following command in the PowerShell prompt that you’ve pulled up to get the process ID number:
Get-ProcessFor example, “5364” is the process ID number for the DimScreen.exe process which is the process you want to terminate. In order for you to kill this process, you need to type in this command:
kill -id 5364
powercfg –restoredefaultschemes
Coming in October for insiders and in November for all in the update, Microsoft has prepared a series of updates which they call an "additional set of experiences"
These updates are looked upon by Panos Panay, a vice executive president at Microsoft & chief product officer for Windows and devices as sort of makeup tests. They will consist of new additions with the biggest one being a tabbed version of File Explorer.

File Explorer received a UI makeover in the last update but the tabbed interface was missing which was expected by many users so it will come in following the next update.
The rest of the features that we will receive are an updated Photos application, Suggested Actions in the Windows Shell, Overflow menu for the taskbar, and improved Nearby Share.
The tabbed File Explorer interface is essentially File Explorer’s version of Sets, the tabbed window interface that Microsoft tested out several years ago. In testing, the tabbed interface proved handy for moving and copying files, and we’d expect the same once the feature formally goes live. The difference between Sets and the tabbed File Explorer interface is Sets allowed for multiple applications to be clustered together via tabs.
Photos app will include a “new photos-managing experience that brings a gorgeous gallery, simplifying browsing, finding, management and consumption of your collection of photos.” It will allow “easy backup to OneDrive” and a “delightful Memories experience.”
As for other features, nothing specifically was said except giving just some tips on what will they bring, it is obvious that File Explorer and the photos app were the main focus for MS in this upcoming update.
RegClean Pro is a program developed by Systweak Inc. RegClean Pro cleans such invalid registry errors using its advanced scan engine. It not only fixes invalid registry entries, it also defragments the registry, keeping it streamlined for smoother system performance.
RegClean Pro defines auto-start registry entities that allow the program to run each time the system is restarted, it also adds various Scheduled tasks in Windows Task Manager in order to launch the application at various times. This application has been found bundled up with various other potentially unwanted applications, also several anti-virus programs have detected this application for optional removal.
“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.
