Stop April Windows Server Updates KB5082063

One of the first Windows Server concepts that finally clicked for me was the difference between Roles and Features. At first, they sounded almost identical. But they serve very different purposes. A Role is the primary job you want the server to perform. Examples: • Active Directory Domain Services • DNS Server • DHCP Server • Web Server (IIS) • Hyper-V When you install a role, the server takes on a core business function. For example, installing Active Directory Domain Services turns the server into a Domain Controller that manages authentication, users, and access across the organization. A Feature adds supporting functionality. Examples: • Group Policy Management • BitLocker • Windows Backup • .NET Framework • Failover Clustering Features don’t define what the server is. They enhance what the server can do. The simplest way I remember it: 👉 Role = Primary responsibility 👉 Feature = Supporting capability That small distinction helped me better understand how enterprise servers are designed. What Windows Server concept made things click for you? #WindowsServer #ActiveDirectory #SystemAdministration #ITInfrastructure #LearningInPublic #CyberSecurity #ITSupport #CloudComputing

Microsoft has released fixes for 138 security flaws across Windows, Office, Azure, and Teams — including two in Windows itself that let attackers run code on your computer or company servers without needing a password. None are being actively exploited yet, but 30 are rated Critical. Microsoft also warns that a security certificate built into Windows since 2011 expires on 26 June 2026 — devices that miss the update before that date face serious boot-level failures. Open Windows Update now and install everything available. 🔥 #CyberNewsLive https://lnkd.in/g4SXDVk8

𝐙𝐞𝐫𝐨𝐃𝐚𝐲 𝐕𝐮𝐥𝐧𝐞𝐫𝐚𝐛𝐢𝐥𝐢𝐭𝐲 ‘𝐌𝐢𝐧𝐢𝐏𝐥𝐚𝐬𝐦𝐚’ 𝐆𝐫𝐚𝐧𝐭’𝐬 𝐀𝐭𝐭𝐚𝐜𝐤𝐞𝐫𝐬 𝐒𝐘𝐒𝐓𝐄𝐌 𝐩𝐫𝐢𝐯𝐢𝐥𝐞𝐠𝐞𝐬 A newly disclosed Windows zero-day vulnerability named ‘MiniPlasma’ allows attackers to gain SYSTEM-level privileges on fully patched Windows 11 systems. ⏏️The vulnerability affects the Windows Cloud Files Mini Filter Driver (cldflt.sys), a core component used by cloud synchronization services such as Microsoft OneDrive. ⏏️Researchers released a public proof-of-concept (PoC) exploit, increasing the risk of real-world exploitation by threat actors and ransomware groups. The flaw enables a normal user account to escalate privileges without requiring administrator access, making it highly dangerous in enterprise environments. ⏏️ The exploit reportedly abuses: ⏏️Weak access validation ⏏️Registry interactions ⏏️Undocumented Windows APIs ⏏️Logic flaws in the cloud synchronization subsystem ⏏️𝐇𝐨𝐰 𝐞𝐧𝐭𝐞𝐫𝐩𝐫𝐢𝐬𝐞 𝐰𝐢𝐥𝐥 𝐚𝐝𝐝𝐫𝐞𝐬𝐬 𝐭𝐡𝐞 𝐫𝐢𝐬𝐤 The vulnerability is still present in fully patched systems running the latest May 2026 updates. The original proof-of-concept code published by Forshaw worked without modification. As the the same underlying weakness still exists and remains exploitable. The flaw allows attackers with physical access to bypass BitLocker protections and gain unrestricted shell access to encrypted volumes through the Windows Recovery Environment (WinRE). ⏏️The flaw is disturbing as the vulnerable component exists exclusively within the WinRE image, not in standard Windows installations, and an identical component appears in normal installations but without the triggering functionality. ⏏️Microsoft has not publicly addressed the claim and neither dedicated emergency patch or confirmed whether MiniPlasma represents a new vulnerability class #miniplasma #WinRE #Vulnerabiity #BitLocker #PoC #Intrucept #Windows #Microsoft #Threatresearch #Cybersecuritynews Intrucept Private Limited Click here to read more : https://lnkd.in/gf5me2jR

Microsoft has confirmed a bug in Windows Update that will stop computers in restricted or firewalled networks from downloading security updates from March 2026 onwards. Affected systems show error code 0x80010002 and may silently fall behind on security patches without users realising. The fix requires IT administrators to apply a group policy setting using a Windows feature called Known Issue Rollback — it cannot be done by ordinary users alone. Machines that stop receiving security updates become easier targets for attackers exploiting known flaws. 🔥 #CyberNewsLive https://lnkd.in/e2q9aYT2

Microsoft Patch Tuesday May 2026 – 120 Vulnerabilities Fixed, Including 29 Critical RCE Flaws May 12, 2026 Microsoft’s May 2026 Patch Tuesday lands with a heavy enterprise focus, fixing 120 vulnerabilities across Windows, Office, Azure, developer tools, and Microsoft 365 apps, including 29 remote code execution (RCE) flaws rated Critical. Unlike several recent cycles, Microsoft reports no zero‑days exploited in the wild or publicly disclosed ahead of the release, but the breadth of attack surface from DNS and Netlogon to Office and Wi‑Fi drivers means defenders cannot afford to treat this month as low risk....

🔐 Share Permissions vs NTFS Permissions  When you share a folder in Windows, two types of permissions decide who can access it and what they can do:  🌐 Share Permissions → Control access over the network.   - Set on the shared folder itself.   - Basic levels: Read, Change, Full Control.  💾 NTFS Permissions → Control access on the local drive.   - Set on the actual files and folders.   - More detailed levels: Read, Modify, Full Control, and more.  ⚡ Both work together:   - Share Permissions decide what happens when someone connects through the network.   - NTFS Permissions decide what happens directly on the computer.  👉 To fully secure your data, you need both.  For a user to successfully open and edit a file over the network, they must pass through both security gates. If they have 'Full Control' on the Share, but only 'Read' on NTFS, they can only read the file. The most restrictive permission always applies. What is your standard practice for setting up file shares? Do you keep Share permissions wide open and rely solely on NTFS, or do you restrict both?

🚨 Critical Fix: April 2026 DC Patching & Kerberos Hardening. If your Domain Controllers have been hitting reboot loops or authentication failures since the April updates, Microsoft’s move into the Enforcement Phase for Kerberos hardening is officially here. The Issue: The April 2026 updates (addressed by OOB patches KB5091157, KB5091575, etc.) now default to AES-only for service accounts. If an account's msDS-SupportedEncryptionTypes attribute is null, RC4 fallback is blocked. This is triggering LSASS crashes and generic "Access Denied" errors. The Fix: 1️⃣ Apply OOB Patches: Stop LSASS reboot loops and authentication failures by installing the emergency updates: Server 2025: KB5091157 Server 2022: KB5091575 Server 2019: KB5091573 Server 2016: KB5091572. 2️⃣ Enable AES: Update Service Account properties in AD to support Kerberos AES 128 and 256-bit encryption. 3️⃣ Reset Passwords: This is the "missing link"—a password reset is often required to generate the new AES keys. 4️⃣ Purge Cached Tickets: Run klist purge -li 0x3e7 (for services) or klist purge (for users) to clear old RC4 tickets and force the request for new AES-encrypted tickets. 5️⃣ Audit Logs: Monitor your DCs for KDCSVC Event IDs 203 and 204 to catch remaining blocked accounts. Also, July 2026 is the final cutoff for legacy support.
