So on April 13th, marks the end-of-support to Windows Vista RTM, which means that customers can no longer receive support benefits from Microsoft and will need to upgrade to either (Vista SP1 or Vista SP2) to continue receiving security updates, hotfixes or assisted support from Microsoft. Microsoft also announced changes to Service Pack Support policy. The revised policy allows Microsoft support professionals to make best effort to provide limited break/fix troubleshooting to customers on unsupported SPs, even without custom support contracts, and help them migrate to supported SP. Microsoft requires customers to transition to supported SPs to receive hotfixes, security updates, time zone updates, or access to sustained engineering. Customers are highly encouraged to migrate to latest supported SP which’s latest & most secure version of their product. Staying on a supported SP’s the only way to ensure continued access to security updates and ability to escalate support issues within Microsoft,” notes Microsoft.
