A recent advisory warns Windows users about vulnerabilities, emphasizing the need to upgrade from Windows 10 to Windows 11 due to the impending cessation of support for Windows 10 in October. Asus has highlighted that users of Windows 10 or older systems will soon lose regular updates and support. Currently, around 750 million users are on Windows 10, with 500 million potentially eligible for a free upgrade to Windows 11. Recent market data shows Windows 10's user share has increased from 41% in April to over 43% in May, while Windows 11 has declined by 3.5%. The urgency for upgrades is heightened as the deadline for Windows 10 support approaches, raising concerns about a potential cybersecurity crisis.
