Before always can,

Just loading system, the use of a Chinese user name, and then in the C: \ \ Users \ is a folder name below, then gradually found that the user folder a small problem with Chinese name will appear all sorts of accidental, simply switch to the administrator account to login this morning, and then the user folder Chinese name changed to all the letters of the English name, and then put the registries have the Chinese name of item, are also correspondingly changed to later English (there are a few items not to change, I also by modifying the permissions are changed),
Switch to change the name of the user to go in, also didn't found anything abnormal, and using regedit sweeps the residues left in the LOCAL_USER Chinese name,
Using the basic normal, but found that on the start menu, type letters, no response; Win + Q also have no reaction, the search box on the task bar, cannot directly input; Can't search for files in the file explorer,
On the Internet to find a lot of methods, reconstruction index (moment was finished, there should be no work), for troubleshooting (searching and indexing) running, change the account to account, such as the local and with mklink creates a link to the original user name in Chinese, points to the English user name folder, now all have no,

But,,, but as long as to create a new user, log in, all of the search function can be used,,,
The original users, however, there were too many various configurations, back again, don't want to use the new users,

Can anyone provide a train of thought? Question will be where?
