I’ve wasted an entire day AND evening on some stupid issues at work. I reinstalled my portable with windows 7 x64. Only to notice that after 6 hours of installing that some software that I need for work doesn’t play nice with x64 (I know because I tested it in x86 where it works just fine). So I decided to install the x86 version of windows 7. I downloaded it and wanted to copy it to my USB stick only to discover that the file copy got stuck around 700 MB left to copy. It seems there is an issue with windows 7 x64 with at least 4 GB ram of copying large files. Microsoft released a so called hotfix: http://social.technet.microsoft.com/Forums/en-US/w7itprohardware/thread/38f25c1d-de67-4c74-8845-2cd3a15d8e41 but as it turns out my system already had this update and it seems that it doesn’t work at all. So now I’m stuck with an >2GB iso file I can’t copy away from my desktop because copying fails halfway through. I recently upgraded my system to 8GB so downgrading to 32 bits is not an option as the extra 4GB will go to waste. Maybe I should put back windows xp x64?

If you recognize this issue and have found a working solution please let me know by posting a comment!
