Windows enterprise customers will be happy to hear about two impending releases that will coincide with the start of the Microsoft TechEd 2005 trade show in early June. First, Microsoft will ship Update Rollup 1 (UR1) for Windows 2000--you know, that "thing" that replaces Win2K Service Pack 5 (SP5) --on June 1. On June 6, the company will release Windows Server Update Services (WSUS, formerly Software Update Services--SUS--2.0) to the Web (a type of shipment Microsoft calls Release To Web--RTW)
