MN 10 is a fake sutta that includes the five hindrances in the 4th satipatthana. Therefore, if the meditator practises for seven days: ‘*I have sensual desire in me*’; they obviously will not make any progress because there cannot be any progress when the five hindrances exist. 

This said, if proper satipatthana (such as described in MN 118) is practised continuously for seven days, i.e., without any hindrances for seven days and with proper samadhi based in '*letting go*' (per SN 48.10 and the end of MN 118), then, yes, certainly that meditator will be a stream-enterer and certainly they can expect one of two results in their life: enlightenment in the present life, or if there’s something left over, non-return.

It is important to distinguish between '*actually practising satipatthana without hindrances*' and '*attempting to practise satipatthana with hindrances*'. 

If a meditator sits one or many 10-day Goenka, Mahasi or IMS satipatthana meditation retreats but continues to have hindrances or uses a wrong method, then this is not actually practising satipatthana. 

In order to develop these Four Kinds of Mindfulness over 7 days, one needs to have perfectly balanced faculties (which depends on one single moment of Right View).
