With Windows XP that would be a 'Yes' given its repair installation option. Vista, however, omits that valuable feature, so the question does not have a clearcut answer. You can run System File Checker to repair/replace key system files, but that does not restore 'all' default computer files. The only way to do restore all of the original files would be to see if the manufacturer included a way to perform a non-destructive recovery from the hidden recovery partition. That would leave your files/settings/documents but repair Windows, reinstall any original third-party software, etc.
As to choosing between 32-bit and 64-bit editions, the key differences to note are:
-> 32-bit only support 4GB of RAM while 64-bit exceeds 128GB
-> 64-bit has less driver support, so less hardware works with it
-> 64-bit requires a 64-bit processor and only provides performance gains with specially-designed software
Hope this helps,
I have Vista home premium(32-bit). which also btw wats the difference if its 64-bit or 32-bit? but anyway i want to know if there is a way to restore like all default files with reformatting it.
