Windows Server 2012 End of Life: Critical Oct 13 Deadline

Microsoft’s September 2026 Patch Tuesday just set a record. CrowdStrike’s analysis of the release counted 972 patched vulnerabilities, more than double August’s count, and 113 of them rated Critical. Two are already being used in real attacks. If your business runs Windows anywhere, on a server, a laptop, or through a VPN, this month’s update deserves more attention than the usual “we’ll get to it”. Inside the September 2026 Patch Tuesday Release This September 2026 Patch Tuesday release patched 972 vulnerabilities in a single cycle, more than double the roughly 415 CVEs Microsoft fixed the month before, the largest release Microsoft has shipped to date. Of those, 113 carry a Critical severity rating, and two are already confirmed to be actively exploited before most businesses had a chance to patch. The volume matters less than the mix: real client-side risk in Office and Outlook, server-side risk in DNS, DHCP, and Netlogon, and infrastructure risk in Hyper-V and VPN services, all landing in the same release window. Two Vulnerabilities Are Already Being Exploited Microsoft confirmed active exploitation of two flaws before most businesses had even applied the patch. CVE-2026-81963 sits in the Windows Update Stack. CVE-2026-85880 sits in a core Windows communication component called ALPC. Both let an attacker who already has a foothold on a device, through a phishing email, a compromised browser, or stolen credentials, jump straight to full SYSTEM control. No extra clicks, no extra warnings. This is the step that turns “someone opened the wrong email” into “the attacker owns the machine.” A Dozen Office Vulnerabilities Need No Click at All Twelve of this month’s Critical fixes affect Outlook, Word, Excel, and PowerPoint, and they share a dangerous trait. Exploitation happens the moment a file is previewed, not opened. If Outlook’s Reading Pane or Windows’ Preview Pane is switched on, which it is by default on most machines, simply receiving a malicious email or having a crafted file land in a shared folder can be enough to run code on the device. CVE-2026-78509 (Outlook) and CVE-2026-78510 (Word) both score a full 9.8 out of 10 and fall into this category. No attachment to open. No macro to approve. No click required. Core Business Infrastructure Was Also Exposed This wasn’t only a desktop software patch cycle. Critical, unauthenticated remote code execution flaws landed in DNS Server, DHCP Server, Netlogon, and Kerberos, the services that handle domain logins, network addressing, and authentication for any business running Windows Server and Active Directory. Hyper-V and the built in SSTP VPN service were also patched for flaws that let an attacker escape a virtual machine or breach an internet facing VPN gateway directly. Left unpatched on exposed infrastructure, any one of these is a realistic path to a full network compromise, not just a single device. The Patching Doesn’t Stop at Microsoft’s Fix Roughly two hours after this month’s patches went out, a security researcher published a new proof of concept targeting Microsoft Defender itself, claiming an earlier fix was incomplete. There is no patch available for it yet. It’s a reminder that a Patch Tuesday release isn’t the finish line for a given month’s risk. It’s the starting point for what still needs watching. What This Means Without a Dedicated IT Team? A record setting patch release is exactly the kind of month where “we’ll update everything next time we’re in the office” gets expensive. Two of these flaws are already being exploited, and a handful more are one proof of concept away from the same fate. This is the gap that managed IT and cybersecurity support exists to close, especially in a month like this September 2026 Patch Tuesday release. Patches get assessed, prioritized by real risk instead of by however Windows Update happens to sort them, and applied on a schedule that doesn’t depend on someone remembering to click Update between meetings.

In the all-digital world of today, companies cannot effectively run without data, applications, and IT infrastructure. But there are unforeseen interruptions like computer attacks, technical malfunctions, or natural catastrophes which can shove the processes to the ground. This is where disaster recovery will come in play. An effective disaster recovery program will ensure companies are able to restore essential systems promptly and reduce downtime, saving money and reputation. What is Disaster Recovery? Disaster recovery is a term that is used to describe the act of recovering information, systems, and IT infrastructure following a disruption. Such interruptions may include hardware failures and human errors, as well as more crucial events such as ransomware attacks or natural disasters. The major object of disaster recovery is to provide business continuity. Organizations will be able to restore their operations within a set time as opposed to losing valuable data or extending their downtime. A disaster recovery plan is normally an element of a larger business continuity plan (BCP), with specific emphasis on data and IT system recovery. Important aspects of disaster recovery are: How Disaster Recovery Works Disaster recovery is a product of planning, technology, and procedures that ensure that normal operations are restored within a short time after a disaster. In a simple overview of how it functions, the following is what happens: 1. Risk Assessment and Planning The first step here is completed by organizations, as they determine potential threats and vulnerabilities. This assists in designing a disaster recovery plan that is specific to certain risks. 2. Data Backup Periodic backups are carried out and saved in safes places out in the cloud or offsite. This guarantees access to information even in cases where the main system may be ruined. 3. Replication and Redundancy Vital systems and information are mirrored on-the-fly or periodically. This redundancy enables companies to change to backup systems without huge hitches. 4. Failover Mechanism Should a failure occur, the systems will automatically transition to a backup server or environment. This is referred to as failover and assists in continuity. 5. Recovery and Restoration When the problem is addressed, systems are reinstated in their natural setting. Data integrity is verified, and the normal operations are restored. 6. Testing and Updates Disaster recovery plans are tested on a regular basis and updated to maintain the effectiveness of the plans against changing threats. This thoroughly organized process provides minimum downtime, short recovery, and less data loss. What Does a Disaster Recovery Server Mean? A disaster recovery server is a special-purpose server that restores and provides backup service in case of loss of the main server. It provides a reserve setting that can carry out operations in case of an emergency. These servers are normally offered in a different physical place or in cloud format so that they are not impacted by the same disaster that has happened to the main system. Key functions of a disaster recovery server include: Disaster recovery servers can be of various types, which include: The correct type is based on the recovery objectives, the budget, and the criticality of the operations of a given organization. Disaster Recovery is Important to businesses. In the absence of an adequate disaster recovery plan, a simple disruption can result in: Having a working disaster recovery system will provide businesses with assurance that they will be able to recover in time and keep serving the clients without serious inconveniences.

The most useful questions to ask your MSP right now have nothing to do with your own network. They are about the tools your provider uses to reach into it. On September 11, 2026, the U.S. Cybersecurity and Infrastructure Security Agency added a critical ConnectWise ScreenConnect vulnerability to its Known Exploited Vulnerabilities catalog after confirming that attackers were already using it in real attacks. ScreenConnect is one of the most widely used remote support platforms in the managed services industry, which means the story is not really about one product. It is about a category of tools that sit at the center of how nearly every managed IT provider reaches into a client’s network. For a small or mid-sized business, the useful takeaway is not which specific vulnerability appeared this week. It is a short set of questions to ask your MSP so you understand how they secure the tools they use to reach you. What Actually Happened With ScreenConnect? The flaw, tracked as CVE-2026-84869, is an improper privilege management and missing authorization issue. In practical terms, it could allow an attacker to transfer files to a device and execute them during an active remote support session without the host user ever approving the action. CISA set a remediation deadline of September 14, 2026, for federal agencies covered by Binding Operational Directive 26-04, and the same urgency applies to any organization running the affected version. The specific patch was straightforward for providers who noticed. The harder question sits one level up: how confident is your provider in their ability to spot, patch, and respond to something like this on their own infrastructure, not just on yours? Why This Matters for Small Businesses? Managed service providers are built on trust and access. A single provider often holds administrative reach into dozens or hundreds of client environments using remote support tools, remote monitoring platforms, and centralized password vaults. That concentration of access is efficient for delivery, and it is also exactly why attackers have been aiming at the provider layer rather than at each client individually. According to the Huntress 2026 Cyber Threat Report, abuse of remote monitoring and management tools now accounts for 24% of all observed incidents, up from 7% the year before. Huntress’s own analysis flagged ScreenConnect specifically, including one case where a rogue install sat quietly for five months before an attacker used it as an entry point. The ScreenConnect entry in the KEV catalog is not an isolated event. It is the latest example of a documented, ongoing trend, and it is why the cybersecurity posture of your provider now matters as much as your own, which is exactly why the questions to ask your MSP have shifted this year. 5 Questions to Ask Your MSP If you already have a managed IT provider, or you are evaluating one, these are the questions to ask your MSP directly. Good providers will have clear, unrehearsed answers. 1. How quickly do you patch the tools you use to reach my network? Ask about their patch cadence for their own infrastructure, not just yours. A provider running weekly patch cycles internally is in a very different position than one that treats their tools as “set and forget.” Our September Patch Tuesday breakdown shows how quickly critical fixes can pile up in a single month. 2. What monitoring do you have on your own remote sessions? Session logging, anomaly detection, and alerting on unusual remote access patterns should all exist on the provider side. If they cannot describe what triggers an alert on their own systems, that is a signal worth paying attention to. 3. Do you enforce multi-factor authentication on every tool that reaches my environment? Every account, every technician, every tool. Not “we use MFA on email.” MFA on the remote support platform, on the RMM console, on the password vault, and on any cloud dashboard that touches client data. Enterprise-grade password managers make this practical to enforce at scale. 4. What is your response plan if one of your own accounts is compromised? The right answer is not “that would not happen.” The right answer is a specific set of steps: session revocation, credential rotation, client notification timelines, and a documented containment playbook. This should also connect back to whatever cybersecurity insurance obligations exist on either side. 5. Are you aligned to a recognized security framework internally, not just for compliance reporting? Frameworks like the NIST Cybersecurity Framework 2.0 and the CIS Controls exist for exactly this reason. A provider who applies these internally, not only when a client asks about compliance, is thinking about their own posture the same way they think about yours. What to Do Next? If you already have a managed IT provider, send these five questions in a short message and see how they respond. The quality of the answer matters as much as the content: unrehearsed and specific beats polished and vague every time. If you are weighing options, bring these questions to ask your MSP into the conversation before you sign anything. A provider who treats these questions as reasonable and expected is showing you how they operate. One who deflects is also telling you something. At Pexo, security posture starts with the tools we use before it reaches the networks we protect. If you are evaluating your options, our managed IT services team is happy to walk you through exactly how we answer each of these questions for our own environment.
