Many of you are thinking slc.dll is the whole RedPill, but NO, IT IS NOT. The real RedPill is "shsxs.dll", right that file doesnt exist, it is loaded at runtime(if it exists), and you need to write your own! And thats your challenge. So what did I found out about the RedPill "shsxs.dll" so far? The shsxs.dll is loaded dynamically from the following files (might be more): TWINUI, EXPLORER, SHELL32, IEUI, DUSER, THUMBCACHE So if that file exists, the named files above are trying to load the dll, after that, it checks if the required functions are in the dll, and if so, the functions are getting called. I've found the following functions so far: RP_VersionCheck() Return Value: 23 RP_Enabled() 1 Return Value: 1 RP_InitLauncherDataLayer(int, int, int) Return Value: 1 RP_CFolderThumbnail_ReadSettingsFromRegistry() Return Value: 1/0 RP_CFolderThumbnail_GetSize(int, int_pointer, int) Return Value: I dont know. RP_CFolderThumbnail_GetCoordinates(int, int_pointer/x, int_pointer/y) Return Value: I dont know. RP_PrivateExtractIconsW() That will be the hardest, look at the original "PrivateExtractIconsW()" and try to rewrite it. But there's a little problem, you should know. RP_CallScheduleGadgetTransitions(int_pointer) Return Value: 1 M1 only (twinui): RP_VersionCheck() Return Value: 65544 (yes, that value is correct) RP_GetLayoutManagerBandDependencies(int, int) Return Value: 1 RP_PickerSetDUIContext(int) Return Value: 1 M2 only (7927): RP_VersionCheck() Return Value: 22 I've been able to write such a dll, but it doesn't work to 100%. I can tell you, the first three functions are to 100% correct. So it would be cool if anyone is able to write a fully working dll. And before I forget it, you need to add a Registry Key: HKCU \ .... \ Windows \ CurrentVersion \ Explorer \ Advanced : SHSXSWasEnabled 1 (And ofc, RPEnabled 1). Another Challenge: Find out what the following RegistryKey does: Explorer\YouBettaHideYoPearl, and what it's required value is (Explorer.exe). solved: hides the startbutton. Hint: This will work in M1 too. Naiveuser, where are you? Please do NOT post in this thread if you don't have anything contributing to say, thanks.
