I made the decision to do a trial of the New Vista OS and decided to do the 64 bit install, as when I upgraded my computer the last time, I went with an AMD 64 Bit CPU and my computer supports the 64 bit system. I tried the 64 bit version but never found enough drivers to get the system to fully operate correctly, essentially there are no drivers / software to use / run on the system. I also found that Microsoft has because of viruses and various software attacks, evidently set the software to mark a lot of files as read only. If you’ve ever worked with the old dos system you know that if your files attributes are marked read only you will have trouble installing software. You can not over-write a read only file. One piece of software that did install did not allow me to save a backup file, I found out that the directory and all sub directories were marked read only. I do not see how a company can expect to release an operating system if required drivers are not available. I am retired and if I had the software (I understand there is supposed to be software that will create drivers or take old drivers and update them for other operating systems)or learn how to write drivers I would be glad to do this for free just to get reliable 64 bit drivers out there for others to be able to access them. Is there any web addresses that focus on 64 bit drivers for Vista and / or 64 bit software? I can not even get the 64 bit version of Office 2007 to install on Vista. In my humble opinion Microsoft has a lot of work to do if they are ever able to release Vista. It is too complicated. Remember KISS (Keep It Simple Stupid)Any help will be much appreciated.
