After Vista, here the next  Windows whose beta release is available to download.
Presented  everywhere like an improved Vista, therefore removed from his heavinesses, I did not hesitate to jump the step. The overall performance is rather satisfactory, one has, indeed, an OS giving a good impression of lightness thus of speed and flexibility, all that misses in Vista.
The famous UAC (this pre-version is in English) is not also any more invading and its threshold of release is now adjustable, of the blow, it can be preserved and does not block any more  installations.

MSTS settles without problem starting from CD of origin, as well as the update. The same applies to the route, rolling stock as well as BINpatch. The editors function perfectly, although always non compatible with Aéro, of course. The play runs smoothly although a route charged in PATHS or SERVICES involves some bugs posting but I had already the same problem under Vista. One gains even in fluidity, in short, only of the good!

Finally, no regret, quite to the contrary…
