Vista 64 Upgrade Warning
By ThinGuy on Jan 29, 2007
A lot of articles popping up on Vista requiring the old OS to do an upgrade. We'll here's a warning of another sort that just bit me almost three months after "upgrading" to Vista 64. The quotes are not meant to say that Vista isn't an upgrade from XP, but rather that you cannot "upgrade" the 64 bit version of XP to the 64 bit version of Vista. A clean install is required.
My problem is that at one point I used XP's Encrypted File System to encrypt a folder that held financial information. Some that being old tax records. All of which I forgot about. Note that when you use EFS under XP, you are not prompted to create a recovery agent. You are however prompted under Vista.
Since the upgrade advisor doesn't work on Vista 64, I have no idea if it would have caught that I had files using EFS.
I got my W2 and wanted to do taxes this week-end. Sat down with TurboTax, went to import 2005 information, only to find out that I was basically out of luck getting my old tax records. Even though it's a clean install, you cannot boot back into the old XP 64 instance to run the mmc for the certificate snapin to export you certificate that would allow you to decrypt the files.
