A fragmented page file forces your hard drive’s read/write head to jump across the platter to retrieve a single piece of data. This dramatically slows down system responsiveness.
Windows operating systems rely heavily on a hidden system file called the pagefile.sys (Virtual Memory) and the Registry hives ( SAM , SECURITY , SOFTWARE , SYSTEM ). These files are locked by the OS while Windows is running. Consequently, standard defragmentation tools (including the built-in Windows Defrag) cannot touch them. Over time, as these files grow and shrink, they become fragmented. Winalign Software Download
