Windows 11 are now significantly improved over the past year, to the point where updates feel like their arriving monthly now. Here we come up with the new update for Windows 11 Insider Preview 25206 build, which offers a vast changelog including new features, fixes, graphics, and more.
This new version of Windows 11 includes SMB authentication rate limiter behavior and a set of fixes to improve the overall experience for Windows Insiders. Alongside you can search from file explorer Home will show recent file activity for the cloud files in the details view.
Let’s explore the changelog for this new 25206 update of Windows 11 Insider to improve the overall experience for the Windows Insiders:
The SMB authentication rate limiter in Insider Preview builds has added an additional protection mechanism to the SMB server service: it implements a delay between each failed NTLM authentication. This means if an attacker previously sent 300 brute force attempts per second from a client for 5 minutes (90,000 passwords), the same number of attempts would now take at least 50 hours.
The goal here is to make a Windows client an unattractive target either when in a workgroup or for its local accounts when joined to a domain. Even though the SMB server runs by default in all versions of Windows, it’s not accessible by default unless you intentionally open the firewall or create a customer SMB share that opens the firewall.
Starting in Build 25206, it is on by default and set to 2000ms (2 seconds). Any bad usernames or passwords sent to SMB will now cause a 2-second delay by default in all editions of Windows Insiders. When first released to Windows Insiders, this protection mechanism was off by default. This behavior change was not made to Windows Server Insiders, it still defaults to 0.
Changes and Improvements
- The updated “Open with” dialog box is now available to all Windows Insiders in the Dev Channel.
- Windows Insiders can now save power by using Dynamic Refresh Rate (DRR) on external displays! To enable this setting, you must have a 120+Hz monitor with VRR (Variable Refresh Rate) support, as well as a WDDM 3.1 driver installed. To select a dynamic refresh rate, go to Settings > System > Display > Advanced display and make your selection under Refresh rate.
- Search from File Explorer Home will show recent file activity for cloud files in Details View.
- Microsoft beginning to roll out a change to support the use of clipboard history (WIN + V) on password fields. Microsoft is beginning to roll this out, so the experience isn’t available to all Insiders just yet.
- OneDrive setup should no longer unexpectedly ask for permission to set up every time your PC reboots.
