[German]Brief question for the Windows users among my blog readers: Did any of you experience problems with Microsoft Defender on Windows 10 or Windows 11 on August 18, 2026? I've received two reports from readers stating that Microsoft Defender crashes during a quick scan on all versions of Windows. And I found several posts in the internet, claiming Defender issues.
[German]On August 11, 2026, Microsoft released a batch of security updates for various Microsoft products (Office, Windows, etc.). It appears that no major disasters occurred after the security updates were installed. However, I've received reports from readers here on the blog about issues (Outlook, Windows, etc.), which I've briefly summarize in a blog post.
[German]I got reports from German blog readers about an issue with the Microsoft Edge browser starting with version 151.x. The browser crashes 5 seconds after start on Windows 10 systems, while it continues to run on other systems.
[German]A German blog reader contacted me about a strange behavior, he faced on hypervisors. Microsoft Defender flags Synology backups on the affected user's servers as a Trojan. As a result, the backups no longer run. The reader wrote to me that selecting "Allow" for this process disables the entire detection rule. And even more striking is the reader's analysis of what triggers Microsoft Defender's response.

[German]I'm posting just a warning for Windows Server administrators using WSUS here on the blog for informational purposes, as it was recently brought to my attention by two readers. WSUS currently cannot be reinstalled on Windows Server and/or fails during the initial synchronization. This is something administrators may encounter if they want to set up a new system with WSUS.
[German]Operators of Fortinet products are at risk of having their instances compromised by attackers. This is because the passwords for administrator access to these instances have been cracked. Attackers can take control of the installations and manipulate them at will. This affects nearly 74,000 instances, as I have read, and is being discussed under the term "FortiBleed." It seems that information on suspected vulnerabilities has been known and patched since weeks.
[German]Microsoft released an update for the Edge 149.0.4022.52 browser in the Stable Channel on June 4, 2026. A reader just informed me that since then, there have been issues with redirecting the Downloads folder to an FQDN URL. As a result, ICA files for Citrix cannot be found. Perhaps others are experiencing the same issue.
[German]The Group Policy Editors (gpedit.msc or gpmc from the RSAT tools) are "broken" in Windows 11; due to a bug, it does not perform the tasks assigned to it by the administrator. Entered values are not applied but are truncated due to an overflow error and then saved. Mark Heitbrink reported this to Microsoft in March 2026 but has not received a response yet.
