Windows Profile problems

Troubleshooting: Using autoruns observation, we found that two sets of "security" software, "Coffee EE" and "360", were installed, and no exception was found in the task manager.
Process:
1. unmount coffee for the sake of insurance, restart and find that the fault persists.
2. the prompt in the lower right corner is displayed: Enable the temporary configuration file. After tracking, we found that the temporary configuration file was used. The original configuration file reached 1.88 GB, which may exceed the quota and be forcibly disabled.
Google "profile exceeds size limit", a bunch of English, lazy reading.
I think of this question in windows internals.
3. temporary solution: create a user account and find that the original fault disappears. It is also normal after restart.
4. Check my computer and find that my configuration file is also 1.74 GB. I copied two large files to other folders and found that the configuration file size became smaller.
