Nice review, Dean! Is it Windows enabled? Their 200 Mbit/s is legit, ah, some VPS provider gives 1 GBit/s on their VPS profile, but not really 1 GBit while doing a speed test. But Contabo different, 200 Mbit/s as they promised in the VPS profile.

And, Europe location only? $6/month for a year, it's so cheap!

Their Windows Policy can be found in their TOS:
§ 13 Licensing terms for Microsoft products

Provided that in the following or preceding section the customer has selected a Microsoft software product (e.g. Windows Server, SQL Server etc.) for installation on his server, he must comply with the current provisions of the "Microsoft Service Provider Use Rights" (SPUR) and the "End User License Terms" (EULT) which apply within the context of the Microsoft "Service Provider License Agreement" to Contabo (hereinafter referred to as provider) if the customer is able to influence the use of the software or could infringe the provisions through use of the software. These provisions may be viewed at the following addresses at any time:

https://contabo.com/spla/SPUR.pdf
https://contabo.com/spla/EULT.pdf

The customer thus agrees to comply with the corresponding provisions and is responsible for observing them correctly.
These provisions may result in only having restricted or even not having the possibility to use otherwise purchased licenses of the customer with the servers of the provider. The provider will supply a license for all customer orders of Microsoft software products considering the Microsoft Service Provider License Agreement. This license allows the monthly use of the Microsoft software product on the server and limits its utilization permission with regard to some aspects. The customer particularly must not use Microsoft products which require additional or other licenses according to SPUR or EULT. The customer is obligated to comply with all these provisions on his own and is liable for violations against this usage policy to the provider and Microsoft.

Fantastic, I haven't got the information needed for this one provider! What about the Uptime ?

Uptime is as expected.  I haven't once experienced down time.  But then you wouldn't find it with places like Contabo or Hetzner.  I'd find it very unusual if it would happen with them.
