Been using WIN 7 Ultimate x64 for a while now, and I quite like it . . . as much as it feels like I've mearly installed SP3 for my Vista Ultimate x64 installation, instead of a whole new OS. Either way, it's responsive, stable, and is what Vista should have been in the first place. BUT . . . . . . I am sick to ever-loving effin death of UAC/VirtualStore/Permissions and all the other "secure" BS that's been duct taped in. Quite frankly - for those who wish to purchase OS7 Home Edition(s), then fine, I can easily see how these "features" will keep the system secure and stable, saving the OS from those who don't know any better. But, for the other versions aimed more at "power users" (i.e. Professional and Ultimate) - get rid of this effin nonsense! At the very least, leave Professional in the "middle of the roads" stance. That is, if logged in as the owner/administrator, no UAC buggary, no VirtualStore tom-foolery, nor "permission denied" shennanigans. Ultimate should simply have the features cut entirelly - except for the "guest" user profile. Seriously - if you're going to aim "versions" of an OS at certain types of users, give them the freedom and versatility they're expecting, not simply the "Home Basic" version with a few (often pointless) features zip-tied into place. It irritates me (and countless others) to no end by being forced to have UAC enabled (as some programs won't work at all if it's even remotely disabled), by being denied simple file/folder operations (copying, deleting, relocating, editing), and having to go on effin safari to find files you just installed (because the OS thought it knew what was best for you and hid them in TwilightZone\ThisFolderDoesNotExist\ThisApplicationDoesNotExist\YouDontKnowWhatYoureDoing\ folder) . . . not to mention the amount of stress and tylenol required to re-assign user permissions, take ownership of files, run applications as an adminstrator and transfer security and sharing definitions over and over and over and over again (because, it seems, Vista/OS7 has extremelly short-term memory and can not seem to remember the owner/administrator setting these security settings 5 EFFIN MINUTES AGO) . . . and all it takes is a simple disclaimer on the boxes of these products (or in the user manual) that states concisely and clearly that usage of the OS via elevated user profiles risk possible system corruption, infection, yadda yadda, bladdidly blah, and MS can not and will not be held liable for your sanity, etc., etc., etc. I understand the point of these features, seriously I do . . . but there are those of us out there who are simply fed up enough with this tripe. Do us the favor of listening to the users . . . and if it means having to re-write the whole OS kernel to make these things happen - get back to effin work, MS. It's left me feeling like I've spent $300+ on a simple Vista service pack (and I'm sure I'm not the only one).
