@JohnWang: I tagger temporally Your config as Caution, since no image system backup solution in Your system.
Please consider to add Macrium Reflect or AOEMI Backupper, both are free and reliable products
As on demands scanner You can also add: ZAM Free, Norton Power Eraser and EmsiSoft Emergency Kit.
Please edit You config (Thread Tools -> Edit Thread) with any further changes and announce them here.
Apart from that, it's a secure config, thanks for sharing
