Win7 Home Premium 64 bit

Runs top:
- Somewhat tidier than Vista
- Be easily self-installed (on a new hard disk)
- Practical: the Windows Explorer as an icon at the bottom left equal accessible
- No compatibility issues so far as the Vista 64bit.
- Why 64 bit: with the 32 bit version, you can manage a maximum of 3 GB of memory, but have 4 GB.
- Start fast and has a lot of support for current hardware

Conclusion: recommendable without restriction, but who has a stable running system does not necessarily need to upgrade, because the earlier Windows versions were also good. Significantly better than Vista if less than 4 GB of RAM are available.

-In addition recommended: Tune Up Utilities, damits also remain stable in the long term.
