Vedant please once try below steps:

Step-(01.) Read the values from registry & store in a list.

List lst = new List();

// Read your registry as per your requirement

Step-(02.) Update your datagridview like below:

foreach (DataGridViewRow m_Row in dataGridView1.Rows)

{

foreach(string str in lst)

{

// Compare your dataGridView1 cell value to registry value

if(m_Row.Cells[1].Value.ToString () == str)

m_Row.Cells[0].Value.ToString () = "true";

}
