I am using a 5 year old laptop which I upgraded to Windows 8 Pro 32-bit in Oct 2012 when Windows 8 was launched. I have the Product Key with me. But now the laptop is proving to be too old and often runs into problems due to old hardware and I wish to buy a new system.
I am interested in the SONY VAIO Tap 20 All-in-One Desktop which comes with Windows 8 Single Language Build 9200 preinstalled. Before buying the new system, I want to clarify few things and I would be thankful if someone can help me here.
1. What are the differences between W8 SL and W8 Pro, apart from the fact that I can't install another language in W8 SL? Can I install Microsoft Indic Language Input Tool for typing in Indian languages in the Single Language version?
2. What are my options if I want to upgrade the W8 SL to W8 Pro?
3. Can I use the W8 Pro Product Key which I purchased online while upgrading my earlier laptop (which is junk anyway), for upgrading the new All-in-One? Please keep in mind that the older laptop has a 32-bit OS while the new AIO will need a 64-bit OS.
