Explanation
Removing the applications from startup can improve the boot time of a PC by reducing the number of programs that load automatically when the PC starts. Some applications may add themselves to the startup list without the user's knowledge or consent, which can slow down the PC's performance. Running the Disk Cleanup utility can also improve the boot time of a PC by deleting unnecessary or temporary files that take up disk space and affect the PC's speed. Disk Cleanup can also remove old system files that may cause conflicts or errors during booting. Installing additional RAM, installing a faster SSD, defragmenting the hard drive, and ending the processes in the Task Manager are not operations that would be best to do to resolve the issue of slow boot time at a minimal expense, as they may require purchasing new hardware or software, or may have negative impacts on other aspects of the PC's performance.
