As Microsoft prepares to end support for Windows 10 on October 14, 2025, a significant number of Indian PCs face increasing security threats. After this date, computers running Windows 10 will no longer receive technical assistance, software updates, or security fixes, making them more vulnerable to viruses and malware.

The end of support for Windows 10 poses several risks. Without regular security updates, new vulnerabilities will not be patched, leaving systems open to exploitation. Malware authors may target these unpatched flaws, increasing the risk of data breaches and cyberattacks. Even with antivirus software, systems without updates remain vulnerable. System performance may also degrade over time without updates, leading to instability and crashes. Software compatibility issues may arise as applications are no longer updated for Windows 10.

India, with its large online population, faces a significant challenge in countering cyber threats. The country is expected to have 900 million internet users in 2025, tripling the population of the United States, which increases the potential volume and variety of cyber incidents. Cyber threats in India include attacks on critical infrastructure, as well as a lack of cybersecurity awareness among users. Sectors handling sensitive financial and personal information, such as banking, financial services, insurance (BFSI), healthcare, and hospitality, are prime targets for cyber attackers.

Cybersecurity incidents in India are on the rise. In the first quarter of 2022, India saw 18 million cyberattacks and 200,000 threats per day, with local governments being a key target. Ransomware attacks are a significant threat, often accompanied by phishing campaigns and social engineering schemes. Malware and IoT attacks are also increasing, exploiting vulnerabilities in network infrastructures. A recent report highlighted that 42% of cyber threats involve malware, 32% involve potentially unwanted programs, and 26% involve adware. Attackers are shifting from opportunistic attacks to more targeted and sophisticated campaigns, leveraging advanced malware types like Trojans and infectors.

Users have several options to mitigate these risks. One option is to upgrade to Windows 11, which offers a more modern and secure computing experience. However, many devices may not meet the minimum system requirements for Windows 11. Another option is to enroll in the Windows 10 Extended Security Updates (ESU) program, which provides security updates for up to a year after October 14, 2025. However, this is a short-term solution. A third option involves workarounds to install Windows 11 on unsupported PCs, but this is not recommended due to potential stability and security issues.

Microsoft is offering an ESU program, but it is limited to one year, leaving devices exposed to risk after October 13, 2026. Consumer groups have criticized Microsoft's plan to halt updates for Windows 10, arguing that it could expose millions to cyber threats and contribute to electronic waste. Some estimate that up to 400 million computers are incompatible with Windows 11 and may be discarded.

To stay protected, users are encouraged to upgrade to Windows 11 if their systems meet the requirements, or enroll in the ESU program for continued security updates. It is also crucial to back up all data before attempting any upgrades or enrollment. Even the most recent antivirus software may not be enough to protect an operating system no longer receiving updates.

The end of Windows 10 support presents a significant cybersecurity challenge for Indian PC users. The transition requires careful planning and proactive measures to ensure continued security and functionality.
