Done.

33 // 3) Set a REG_QWORD value with the timestamp of the reset. This value should | |
34 // be obtained from a call to ::GetSystemTimeAsFileTime(). This value | |
35 // will be persisted in a reset profile and will be used to avoid | |
36 // multiple resets. | |
37 // | |
38 // Some considerations: | |
39 // | |
40 // * Chrome supports multiple profiles. When the above steps are followed, | |
41 // each profile will enter the reset flow as it is opened. | |
42 // * New profiles created while a timestamp is present will not get the reset | |
43 // flow. | |
