The above is the income from some improvements accumulated over the years by the author. It is recommended that users (novice above) install oneoptimizationMaster 6.5 or above, after registering through the registry, the memory can be sorted out, and even if a large number of junk files and some junk registration information can be deleted. In the process of deleting the primary and secondary information of the garbage, the optimization master will prepare the information to be deleted. The author believes that those reserved points are really useless, so you can delete them. You can delete all files in the wom\backup\registry directory of the optimization master. Save a lot of space.
