Answer 1

Delete the

C:\\Users\\hy\\AppData\\Local\\Microsoft_Corporation\\LandingPage.exe_StrongName_ryspccglaxmt4nhllj5z3thycltsvyyx\\

directory, and try again.

I believe the uninstall sometimes does not clean up the files completely.

Answer 2

如果您搜索%localappdata%\\Microsoft_Corporation%您应该能够找到它

Answer 3

Search in this folder: C:\\Users\\user_name\\AppData\\Local\\Microsoft_Corporation

There you will find files or folders like

• LandingPage.exe , or
• LandingPage.

Delete all these folders. Works for Windows 10.

Answer 4

删除此文件夹C:\\Users\\yourName\\AppData\\Local\\Microsoft_Corporation\\LandingPage.exe_StrongName_ryspccglaxmt4nhllj5z3thycltsvyyx\\

C:\\Users[USER_NAME]\\AppData\\Local\\Microsoft_Corporation\\LandingPage.exe_StrongName_ryspccglaxmt4nhllj5z3thycltsvyyx\\10.0.0.0

to

USER.CONFIG.BAK
