I have just installed sp1 build 1106 last nite.. xp's looking good i have checked the version/build info "string" and compared them against screenshots from various sites & forums... i am pretty convinced that this build is final... but is there any way to make sure? i am thinking of downloading the "official" release from MS server and do a CRC check / binary compare of both files.. but i am not sure if this will work, as they may differ in terms of digital signatures etc, but they maybe the same final code packaged differently... suggestions, anyone? anyone know if the 1st version of uxtheme.dll will work on xp with sp1? and if it's not, where can get a version that works with sp1? i have checked tgtsoft; and wanna avoid installing stylexp... please help..
