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!
Windows Defender Application Guard inside Windows Security App
Windows Defender Application Guard is designed to prevent attacks on local machines and from expanding malicious activity throughout a corporate network. If you are interested in learning more about Application Guard and how to install it in standalone mode, please see our previous blog. In the upcoming Windows release (Build 17691+), we have built an interface to configure Windows Defender Application Guard inside the Windows Security app. This allows users to configure Application Guard or check the administrator’s configuration of Application Guard at the same place as other Windows security features. The four settings that can be configured for Application Guard in the Windows Security app are: Save data Copy and paste Print files Advanced graphics Standalone users with devices that meet the minimum requirements will see Application Guard in the Browser & apps control section in Windows Security. From there, users can invoke the installation of this feature and configure its settings. When devices fall below the minimum spec, users will be alerted of this in the configuration page for Application Guard. Managed users can see how their administrators have configured their settings to have a better understanding of how they can operate between an Application Guard container and their host system. Here’s how users can configure or check their Application Guard status: Install and configure Go to the Windows Security app and select “App & browser control.” Select “Install Windows Defender Application Guard” under Isolated Browsing. Check the “Windows Defender Application Guard” box and Install from the Turn Windows features on or off screen and click OK. Restart your device. Return to the Windows Security app and select “App & browser control.” Select “Change Application Guard settings” to configure the settings. View managed Application Guard settings Go to the Windows Security app and select “App & browser control.” Select “Change Application Guard settings” to view the settings. Review the configurations set by your administrator. We encourage Windows Insiders to use the Windows Security app to configure and view Application Guard settings. Your feedback, suggestions, and telemetry will help us to improve Application Guard’s user experience. Feedback Hub link: Launch Windows Feedback for Microsoft Edge\Application Guard
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.Windows security malware removal problem

Windows 11 Dynamic Lock Unstable
Dynamic Lock in Windows 11 is unstable. Even when phone is connected to PC via Bluetooth, Dynamic Lock says it can't detect your phone. This screenshot shows: my phone is connected but dynamic lock shows not detected. Sometimes it works if I press the Scan for Phone option manually. But its not intended to work like that.
Windows Security Real Time Protection can't be enabled
I am currently running Windows 11 Pro Insider Preview 23H2. I tried enabling real time protection in registry by settling real time protection key to 0, I tried to set not configured for real time protection in Local Policy Group, I have alo tried enabling it using Command prompt. However, none of the steps worked. Real time protection is still off and cannot be enabled. It just keeps on toggling off even when manually toggling it to on. I do hope that next Windows Updte would have a fix to this issue.Control Flow Guard caused tasks to suspend on launch
I've been tracking down the cause of a really troubling problem that started 5-6 x64 canary releases ago: running some executables would lead to a delay of 20-30 seconds before the application would actually launch. Discovered they were starting but immediately going into a suspended state (viewable in Task Manager) for up to 30 seconds, then they would appear on the screen and function normally. An example is Notepad++. I could repro the issue on demand by launching the app and then terminating it and then executing again a few times in rapid succession. Disabling Control Flow Guard (CFG) in Windows Security, App & Browser, Exploit Protection seems to resolve the issue. Reported in feedback, where there were about two other reports of similar behavior. Anybody else seeing issues with CFG ?
