Windows 8.1 upgrade - update info not rumors (NEW) link added « on: June 05, 2013, 08:28:50 PM » If you have x86 Windows 8 and if you upgrade to the pre-release editions of 8.1 then if you upgrade to Release Edition of 8.1 you will have to reinstall all your apps.... There was not mention of x64, but so far every body has recommended (DO NOT UPGRADE YOUR CURRENT WINDOWS 8 TO ANY PRE-RELEASE EDITION) when the final RTM Release in Aug or Sept come outs... you have to Re-Install all Apps, one even said Office also. If you wait until the Official Release is a STORE you do upgrade from Windows 8 to Windows 8.1 RTM all things upgrade properly. Now this is only a RUMOR or GOSSIP I have seen on the WWW... not official from M$...
