As the clock ticks on support for mainstream Windows 2000 users, Microsoft has released a "high priority" update containing more than 50 security fixes.
Rollup 1 for Windows 2000 SP4 was released last week, just days before mainstream support expires on June 30.
The rollup contains fixes that were issued between the release of Windows 2000 SP4 and 30 April 2005. It contains a variety of fixes for files that have not been part of previous updates, so it should be applied even on systems that have been kept up-to-date, Microsoft says.
The rollup is listed as a "high priority" update on the Windows Update website, and will be placed under the "critical and service pack" categories.
But Microsoft is transitioning Windows 2000 users to a new Windows Update site over the next few months. The rollup will be listed there under the "critical and service packs" category, it says.
While last Thursday marked the end of support for so-called mainstream Windows 2000 customers, the software maker also offers extended support until 30 June 30 2010 for a fee. All customers will receive free security hotfix support through to 31 March 2010, however.
More information on the rollup is available on the company's website.
