No, it is not booting up very fast, but it is still ok as I usually don't reboot that often. I remember one severe increase in the user login duration, and this was caused by the high number of files in a temp folder which Disk Cleanup somehow did not delete. Manually deleting those solved this issue, and over the years, I have only used the standard tools included in Windows to maintain the system. No tuning or cleaning tools that defrag the registry, download some RAM or do some other magic.
