Microsoft Users: India’s national cyber security agency CERT-In has issued a serious warning for Microsoft users. According to the agency, serious flaws have emerged in many popular Microsoft products which can be misused. This alert has been issued on January 14 under CIAD-2026-0002 advisory and has been placed in the high-severity category.
Which Microsoft products are at risk?
According to CERT-In, this security flaw is not limited to just one software. Windows operating systems, Microsoft Office, Azure services, SQL Server, developer tools, and even systems running Extended Security Updates (ESU) are vulnerable.
This warning is not only for big companies or IT teams, but is equally important for ordinary users who use Windows computers for daily work.
Active exploit increases concern
This alert is being considered especially serious because CERT-In has confirmed a security flaw which is being actively misused. This flaw is related to Windows Desktop Window Manager which is tracked as CVE-2026-20805.
In simple words, if an attacker gets local access to the system, he can steal sensitive information without any noise. Such attacks often go undetected until considerable damage is done.
What could be the impact on the system?
CERT-In has warned that if these flaws are not fixed in time, then many types of cyber attacks are possible through them. This includes remote code execution, gaining system control, identity theft, data theft, and even complete system crashes.
In some cases, infected computers can also be used to spread ransomware or leak data on a large scale.
Why is caution important for common users?
People often believe that cyber attacks target only big companies, but this alert from CERT-In clearly shows that ordinary Windows users are also at equal risk. If the system is not updated, the computer may become unsafe even without any clear indication.
What is most important to do now?
The safest step right now is to immediately install Microsoft’s latest January 2026 security updates. Along with this, limit unnecessary access, keep an eye on suspicious activities and always keep the system updated. Small precautionary steps are the most effective way to protect Microsoft users from major cyber threats at this time.
