When managing startup services, it is important to note that disabling or removing services typically does not delete restore points in Windows. Restore points are created based on system settings and are not directly affected by the services running at startup. However, if the system runs out of space for new restore points, it may delete the oldest ones to make room for new entries. Users can manage startup programs through the Control Panel and browser settings to improve boot times without impacting restore point functionality.Disk defragmentation can enhance performance, but its effects may be limited if the file structure is not severely fragmented. Upgrading RAM can significantly improve performance, especially if the system is using 100% of available memory. Transitioning the operating system drive to an SSD can yield substantial speed improvements due to the faster data access speeds compared to traditional hard drives. Additionally, regular malware scans are recommended, as malware can significantly degrade system performance.
