I used to have a Windows 8 Pro machine1. When the preview came out, I decided to try it, assuming that there would be a clean upgrade option after the full version came out. So I downloaded the iso from the Windows site and used the key provided to install it.
It seemed to work, though of course there was the "Windows 8.1 Pro Preview Evaluation copy" message at the bottom.
Now, as the full 8.1 is out, I got the iso and key from DreamSpark, and want to switch to it.
On mounting the iso and starting the installation, it gives me two options:
- Keep only personal files
- Keep nothing
This does not bode too well. I'd rather not lose my installed programs (apps are fine).
I do know that I can update using the Store, however the Store does not work behind an authenticated university proxy2. So my only option is to update from the iso, which may lead to the loss of my programs.
How can I do this without losing my programs?
(If anyone thinks they have a way of fixing the Store to work with an auth proxy in 8.1, let me know in a comment and I'll ask it separately)
1. Dual booted with Ubuntu with UEFI turned off, but that probably isn't relevant.
2. The fix for this via CCProxy doesn't work anymore for some reason; and though I hear that 8.1 has better proxy support, I haven't managed to set it up so that it understands the proxy.
