Driver digital signature authentication issues
I am currently developing a desktop application for my company with a kernel driver (which is just a single .sys file). Since drivers must have a Microsoft digital signature to run starting with Windows 10, I have some questions about digital signature authentication. On this webpage (https://learn.microsoft.com/zh-cn/windows-hardware/drivers/dashboard/driver-signing-offerings#hardware-lab-kit-tested-and-dashboard-signed-drivers), I saw a solution for driver signing. The first method requires testing with HLK and submission to Windows Hardware Quality Labs for certification. The second method, according to its description, only requires submitting the driver for signature verification, without HLK testing. What are the differences between these two solutions? Which solution should I choose?
Windows update made dell laptop into a brick
Last security update on Jan 13th broke my laptop. Every program keeps freezing and doesn't do anything. Even when I open task manager it may run for a minute but soon it will freeze, and can't even end task. Only thing that is working is my browser. Yesterday I managed to reinstall windows using a USB and it was working again. While i was away, it forced an update and once again the same issues arise. laptop is too old to install 11, and going to try and reinstall windows again. There a way I can turn off the windows 10 update before this happens again? there is a patch, but i cannot install it. When it automated update, it bricks again and i can't install the most recent patch. it's in a never ending loop of hoping it doesn't auto update when i leave the computer on, or reinstall the OS with a usb.

Microsoft Account Troubleshooter: not updated since Oct. 2013
Hi! I downloaded today (2020-07-14) the tool ( https://social.technet.microsoft.com/wiki/contents/articles/13976.how-to-troubleshoot-microsoft-account-issues.aspx ) and opened it with 7-zip. The files there are from Oct. 2013. It means that the tool might not know about changes to account authentication. Therefore, it may report wrong conclusions/detections. I may be wrong but it seems to me that the tool needs some updating.Turn on Mandatory ASLR in Windows Security
I've been using it for quite a while now, it caused no problems or errors with any legitimate programs, games, anti cheat systems etc other than with some "custom" made portable programs. it's Off by default, when you turn it on, you will have to restart your device. Address space layout randomization Address space layout randomization (ASLR) is a computer security technique involved in preventing exploitation of memory corruption vulnerabilities. In order to prevent an attacker from reliably jumping to, for example, a particular exploited function in memory, ASLR randomly arranges the address space positions of key data areas of a process, including the base of the executable and the positions of the stack, heap and libraries. The Linux PaX project first coined the term "ASLR", and published the first design and implementation of ASLR in July 2001 as a patch for the Linux kernel. It is seen as a complete implementation, providing also a patch for kernel stack randomization since October 2002.[1] The first mainstream operating system to support ASLR by default was the OpenBSD version 3.4 in 2003,[2][3] followed by Linux in 2005. https://en.wikipedia.org/wiki/Address_space_layout_randomization https://blogs.technet.microsoft.com/srd/2017/11/21/clarifying-the-behavior-of-mandatory-aslr/ Other options that are tuned off by default and you should enable to make your Windows device more secure With the increasing number of threats in cyber security and new ransomwares, If you are only relying on Windows 10's built in security and not using any 3rd party AV such as Kaspersky, you must enable these features to keep yourself secure. Hope everyone stay safe!
