EnterpriseProfileCreationKeepBrowsingData

If this policy is Enabled, the option to keep any existing browsing data when creating an enterprise profile will be checked by default. If this policy is unset or Disabled, the option to keep any existing browsing data when creating an enterprise profile will not be checked by default. Regardless of the value, the user will be able to decide whether or not to keep any existing browsing data when creating an enterprise profile. This policy has no effect if the option to keep existing browsing data is not available; this happens if enterprise profile separation is strictly enforced, or if the data would be from an already managed profile.
