Huge, doesn't uninstall, and installs almost to your kernel.
Tried to uninstall it and it kept itself hidden safely in File Explorer, not uninstalling. Has a lot of spam, too. Had to use the trial version of Revo Uninstaller Pro, it removed about 10,000 registry keys, gigabytes of space, and a ton of files, ALL related to WPS. So many files were removed that I thought Revo overshot and ruined the computer, but after reviewing the files and registry keys it turned out that Revo was correct. WPS really did infiltrate the system that much. This is horribly creepy and unsettling software. These types of installers should be illegal. I would rather use notepad.
