It work! 100% I tryed it. gained 40gb source: http://tech.yahoo.com/news/pcworld/...tasp2readersreportbigincreasesinfreediskspace
really, where is this magic space coming from? no where. most likely replace a crap load of useless system files that were unnecessarily huge..
the system should have a system restore, try to restore the system. this is why i don't upgrade my windows unless i have backed everything up and it's at a time where i don't need my computer for work.
Windows has the habit of creating restore points before installing updates/service packs. I'm sure this is no different. I'm not suggesting that the Service Pack 2 deletes the restore points but the results are awful similar.
I might just install it for my laptop now. That clock thing has been using up so much ram, makes the comp SO slow... I could do with more HD space too.
