I have purchased a new T61 recently. It came with Windows vista Home basic. I installed several programs such as MS Office and Adobe Photoshop.
Then, I purchased Windows vista Ultimate version. After I upgraded to Ultimate version, C drive has changed to SW_preload and I cannot open any programs under this drive.
How can I use the programs that installed before I upgrade Windows?
If I recall correctly, "SW_preload" is the drive's label (or name). You can change this to anything else that suits your fancy.
I suspect your MS Office and Adobe Photoshop programs were lost, and you will have to install them again.
