I there any method to sleep the thread upto 100.8564 millisecond under window OS. I am using multimedia timer but its resolution is minimum 1 second. Kindly guide me so that I can handle the fractional part of the millisecond.
Yes you can do it. See QueryPerformanceCounter() to read accurate time, and make a busy loop.
This will enable you to make waits with up to 10 nanosecond resolution, however, if thread scheduler decides to steal control from you at the moment of the cycle end, it will, and there’s nothing you can do about it except assigning your process realtime priority.

Several frameworks were developed to do hard realtime on windows.
Otherwise, your question probably implies that you might be doing something wrong. There’re numerous mechanisms to trick around ever needing precise delays, such as using proper bus drivers (in case of hardware/IO, or respective DMAs if you are designing a driver), and more.
Please tell us what exactly are you building.
