For privacy protection and data security purposes, it is very necessary to set a login password for the Windows user in use in many environments (especially the public places). But sometimes, we may forget our login password for those computers we don't use very often, or remember the wrong password, and fail to log in. This case, reinstalling the operating system is a inadvisable bad plan; and taking brute-force password cracking is extremely inefficient. Therefore, clearing the original user password has always been the first choice - also the easiest and most efficient way.

The reason is very simple, likewise as the pioneer and classical documents packaging & compressing applications, WinZip had been completely defeated by WinRAR for many, many years. Plus the free, open-source and extremely high compression of 7-Zip, WinZip has less future. Even it was acquired by Corel Corporation in 2006, WinZip still has no capability to survive in the file archiving field. Finally, it either disappears from the historical stage, or just descends to a bundled software of Corel products line, or derives many trend-following sister products, until finally disappears forever.
