empty temporary files and recycle bin
delete temporary files by going to settings > system > storage > temporary files and select items like temporary internet files, delivery optimization files, and recycle bin contents, confirm the items before deleting, also manually empty the recycle bin on the desktop, these steps are safe and often free up gigabytes quickly.
uninstall unused programs
open settings > apps > apps & features and sort by size or last used, for programs you no longer need, select uninstall, be cautious with programs you do not recognize, check online if unsure, games and large apps often take the most space, removing them can recover significant room on c:.
move personal files to another drive or cloud
large photos, videos, and documents can be moved to another internal drive, an external hard drive, or cloud storage (onedrive, google drive, etc.), cut and paste folders from c:\users\yourname\documents or downloads to the new location, after confirming files open correctly from the new location, delete the originals on c: to free space.
use disk cleanup and system restore management
run disk cleanup, search disk cleanup, choose c:, and select system files, this tool removes old windows update files and system cache, also manage system restore, right-click this pc, properties, system protection, and configure disk space used for restore points, reducing the space used for restore points can free several gigabytes but keep at least one recent restore point for safety.
disable hibernation if not used
if you do not use hibernate, turn it off to delete the hibernation file, open command prompt as administrator and run powercfg -h off, this removes the hiberfil.sys file, which can be several gigabytes, re-enable with powercfg -h on if you need hibernation later.
move pagefile if you have another drive
windows uses pagefile.sys on c:, if you have a fast secondary drive, you can move the page file there, open system properties > advanced > performance settings > advanced > virtual memory change, set c: to a smaller size or no page file and add a page file on another drive, do not delete the page file without setting a replacement, restarting is required.
keep c: clean regularly
set a monthly reminder to run storage sense or manual cleanup, empty downloads regularly, uninstall programs you no longer use, and move new large files off c: as soon as possible, regular maintenance prevents future full-disk problems and keeps the system responsive.
