Fixing broken registry items and removing unnecessary elements like leftover files from uninstalled software, invalid startup entries, and dead shortcuts will prevent error messages and crashes.

FAQ

Is defragging still necessary?

Defragging is still important for traditional HDDs. As files are added, modified, and deleted, data becomes fragmented and scattered across the disk. This fragmentation slows access times because the read/write head must move more to retrieve a single file. With AVG TuneUp, your drive type is detected, and the proper optimization is automatically applied.

What does disk defragmentation do?

Disk defragmentation reorganizes scattered data into continuous blocks, making files easier to access and improving overall system performance. This process helps reduce load times and can extend the lifespan of your HDD. Performance tools like AVG TuneUp automate defragmentation, ensuring your device stays optimized without the need for manual maintenance.

Do SSDs need defragmentation?

No, solid state drives (SSDs) don’t require defragmentation. Unlike HDDs, SSDs use flash memory with no moving parts, allowing for immediate data access regardless of file location. Defragmenting an SSD offers no performance boost and can actually reduce its lifespan. AVG TuneUp recognizes SSDs automatically and skips defragmentation, focusing instead on safe optimization methods like junk file cleanup and startup app management.

How can I run Microsoft Disk Defragmenter?

To defrag your Windows 11 hard drive, first go to Start > Settings > System > Storage > Advanced storage settings > Drive optimization. Then, choose your drive and click Optimize. On Windows 10 and older versions, search for Defragment and Optimize Drives in the Start menu. If you want to save time and hassle, use a PC Cleaner tool, which can defrag and clean your PC in other ways.
