Hi SyamandhakamHome,
I'm Paul and I'm here to help you with your concern.
You can use the command prompt to clean the Temp folder.
> Open Command Prompt (Admin) or PowerShell (Admin) from the list.
> Copy-paste the command below and enter.
del /q/f/s %TEMP%*
> Close the command prompt and restart the PC.
I hope this helps. Feel free to ask back any questions and keep me posted.
