Dear Mr Vanderpool. I am a computer scientist and have been working in IT security as malware analyst for 6 years. I decided to keep learning by watching one technical video every day and that's how I found your channel as I was looking for things on Windows internals. Thank you very much for your videos. I like especially the old ones with the lectures because it feels like sitting in a class room again and your teaching style is very engaging and passionate. I learn a lot from your videos and I also recommended your channel to my colleagues. Thank you!
I've been watching IT-related videos here for years now, and while there are many great ones out there, this here is lightyears ahead of anything I've encountered so far. it's well-structured, goes in-depth but starts with the basics, and is really easy to focus on and follow. I rarely leave comments on here, but this is some impressive work I'd usually not expect to be available for free.
Thanks! I was just thinking I should probably start to learn about the Windows Registry and then you uploaded this. Appreciate all the effort and knowledge you put into this. Thank you!
It makes me sad that I only recently discovered your Channel. Thank you for sharing. You are truly an amazing teacher. Cancelled my Netflix b/c I will be binge watching the videos on your Channel.
Excellent content as always. This really helped to clarify some questions that I had regarding registries in general. Thanks so much for all you do for we IT pros who want to grow.
Great work, Great videos, Clear Teaching, Quality content, Nice and cool presentation, Rare videos, Life saving videos for a tech. Expecting more videos. Thank you so much Mr. Lowell Vanderpool.
Thank you very much for all of your videos. I have found your content on Windows to be particularly helpful. This one of the only channels that goes "under the hood" of this operating system. I'll definitely recommend you to my peers.
Thanks so much for sharing your knowledge. This was my first video of yours. First thing that came to mind was, you are the Bob Ross of IT. I'll certainly be back for more.
This video is more than useful that gives most of the informations you need to understand the windows registry, you are more than awesome thanks, may God all mighty reward you for your efforts 😘
This video is amazing, I'm studying the MTA 98-365 Server Administration fundamentals and this goes into great detail as the book I'm using only briefly goes over it.
@@TechsavvyProductions Thanks for the reply, Shall do. I'm using multiple sources including your videos. Thank you for the content it is really appreciated, the pdfs are so handy.
Sir I have a question, is it possible to delete whole files of uninstalled software from computer without leaving single data regarding currently uninstalled software.....?
Sir I have more doubts when r u free sir so that I can contact u and have a continuous conversation for a while.....I am eagerly waiting for ur reply sir😆😆😆😃😃
Hi Lowell! today everybody is talking about the virus so this is good to return to basics and watch a good Windows video :):):) By the way, I always thought HK was for "Hive" and not "Handles", i don't know why... And last question, do you know something about the HKLM\COMPONENTS key? because I solved many issues on Windows computers at work by removing or modifying this key that is supposed to be "hidden" most of the time, but I don't really understand the root cause of the problem (why this key is suddenly stuck online...)
You stay healthy over there in the great country of France! The HK is handles although who would argue if you called it Hive? Thanks for sharing your experience with HKLM\COMPONETS key, I will look into this, sound interesting.
This is very helpful. Thanks for sharing it. Needed 1 help understanding, any registry changes I make in Registry editor, that it's not reflected when I try to access them in powershell and when I update registry from a PowerShell and get it, I see the updated one but not in the registry editor or next powershell window. Is any registroy update is volatile in nature and it's only visible in that session (powershell session or registry editor of that session?) What's required to reflect the update everywhere?
Awesome Videos, Professor Vanderpool! Your videos are helping me excel through my Cybersecurity Program at GCU. Your hard work in producing these videos is greatly appreciated. Thank you so much!
Im trying to learn how to configure and administer Windows. Not only that but how Windows works and the various components that make up the operating system do you have any advice sir on what videos I should watch on your channel and labs/projects I should create?

Dism is used to check the files of the operating system and replace or download missing or update incorrect versions. It does not fix the registry. System restore is your best option for restoring the registry. www.howtogeek.com/howto/windows-vista/using-windows-vista-system-restore/
There are 200+ registry entries that launch executable code, that creates plenty of problems. The registry structure is such that it can not store files. Your HD is designed for that.
All the major operating systems are amazing and developed by some of the most brilliant software engineers in the world. The Mac-OS, Android, iOS, Linux, BSD, Windows and UNIX are all different in some respects but are all corporate and enterprise ready. Using a registry concept for system and application configuration is simply a Microsoft choice.
I am very happy you are creating such a great videos. Even I am intro IT and I know a litte bit - its always good to know more. I would like to ask you. Can you point any indicators for cybersecurity guys? Create rule - if anyone would try to change SAM folder then trigger the alert? I am just trying to think forward and understand.
You are thinking about security very well! You can setup auditing for the file and then using event viewer to run a batch file to either email you or text. This requires extra software but it can be done.
My question Mr V is that I always see that DWORD as 32 bit when making changes, "but" if it's a 64 bit OS then why isn't the QWORD used more often . I have yet to find anyone to explain this to me, it's like the registry is resorting to the WOW64 with backwards compatibility to 32 bit (DWORD) I think this is real odd that if you wanted to take full advantage of a 64 bit operating system you would use the QWORD for registry changes I do registry backups on my main computer weekly
John very good question and astute observation, 32-bit values can be easily be converted to 64 bit values (binary computers do this with little impact on performance). I imagine much of the 32 bit conversion of Windows to 64 bit had limited change on the 32-bit original registry.
hello sir and thank you for your valuable services , i had been studying from your videos for about a month . Your videos will get me through the interview and finally a job HOPE SO .. such a clear understanding on topics helped me but sir plzzzzzzzzzzzzzzzzzzzzzzzzzzzz upload more videos on topic "ACTIVE DIRECTORY" their are only a few of them ..and every1 is telling AD like "waaaaa its very tough , very tough " . help us to understand sir . thank u
How do I open files as administrator,when a hacker hacked my laptop? And they set themself up as the administrator now.What can I do,to kick them off as administrator?
If you know for sure you have been hacked, from a security stand point download a fresh copy of Windows and format the laptop hard drive and reinstall. You can not be certain of the condition of the laptop even if you regained admin rights on the laptop.
Hi I have a problem with my WiFi when I start my PC it works OK but after a few hours it shuts off & I cannot turn it back on , when I try to open wlanext. Exe a command prompt opens 8 it closes very quick . I want to ask you what is the correct registry value for wlanext. Exe ?
Babak Gholian, it sounds like your Transmitter chip is overheating and causing the WiFi card to fail. Can you reboot and everything works fine? How long does the card work until it stops. WiFi transmitter amplifiers draw 90% of the current for your card and often overheat and fail.
Hello sir i got blue screen problem because i changed random regiatry i m so fool please help me get back i have tried allll the methodss..i canbot ubderstand please help.
I think a lot of our many problems would run better and faster if windows in the future incorporated the way linux does things, because in linux there is no registry.
Here’s how you can create a shortcut Ctrl + Alt + NumLock = Fn and enable/disable hotkeys with it in regedit: Open Registry Editor by pressing Windows key + R and typing “regedit” into the Run box. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout. Right-click on Keyboard Layout and select New > Binary Value. Name the new value “Scancode Map”. Double-click on Scancode Map to open it. In the Value data field, enter “00 00 00 00 00 00 00 00 02 00 00 00 3A 00 45 E0 5B E0”. Click OK to save your changes. Restart your computer for the changes to take effect1. I hope this helps!

if you mess up a reg key badly,, can you use dism to repair it?
Dism is used to check the files of the operating system and replace or download missing or update incorrect versions. It does not fix the registry. System restore is your best option for restoring the registry. www.howtogeek.com/howto/windows-vista/using-windows-vista-system-restore/
Stupid question but, what would it mean if there WAS executable code in the registry, out of curiousity.
There are 200+ registry entries that launch executable code, that creates plenty of problems. The registry structure is such that it can not store files. Your HD is designed for that.
Simply Amazing!!
Thank you! Cheers!
What’s your opinion on unix-like systems that don’t utilise a registry?
All the major operating systems are amazing and developed by some of the most brilliant software engineers in the world. The Mac-OS, Android, iOS, Linux, BSD, Windows and UNIX are all different in some respects but are all corporate and enterprise ready. Using a registry concept for system and application configuration is simply a Microsoft choice.

@@TechsavvyProductions thank you so much
Hold up how can I enchance the security with registry or în group policy
Group Policies are an important method of securing Windows clients and servers, GPOs often edit the registry to enforce a security policy.
@TechsavvyProductions I have a about restore point:You need to put your system on administrator right when you create restore point ?
Is true that registry edit can be only create a file or keys inside hive ?(I mean malicious key or folder if somebody want to do în your computer)
The registry is a unique database for holding specific data, not files, hackers do use the registry to "auto-run" their code.
@TechsavvyProductions what about creating like a new registry and put some code=trojan or malware
My question Mr V is that I always see that DWORD as 32 bit when making changes, "but" if it's a 64 bit OS then why isn't the QWORD used more often . I have yet to find anyone to explain this to me, it's like the registry is resorting to the WOW64 with backwards compatibility to 32 bit (DWORD) I think this is real odd that if you wanted to take full advantage of a 64 bit operating system you would use the QWORD for registry changes I do registry backups on my main computer weekly
