1. Use the built-in cleanup tool of the operating system<\/p><\/h2>\n\n\n\n General Notes<\/strong><\/p>\n\n\n\n When you delete files on Windows, they are usually still stored in the Recycle Bin<\/strong> and take up disk space.<\/p>\n\n\n\n To clean quickly, right-click on the Recycle Bin icon on the Desktop \u2192 select Empty Recycle Bin<\/strong> \u2192 confirm. If you want to delete specific files, open the Recycle Bin, select the files to delete, and press Delete, or choose Restore<\/strong> to recover them. You can go to Properties<\/strong> to limit the bin’s storage size or enable the option to delete files permanently without storing them here.<\/p>\n\n\n\n Windows often stores many temporary files (cache, logs, installation files) in the Temp<\/strong> folder, which can take up a lot of space over time. You can delete them to free up disk space:<\/p>\n\n\n\n How to do it:<\/strong><\/p>\n\n\n\n Note:<\/strong> Some files currently in use by the system cannot be deleted \u2014 choose “Skip” when you encounter a notification. This does not affect Windows as these are just temporary files, but you should close any running applications before cleaning to delete more files.<\/p>\n<\/blockquote>\n\n\n\n Unused applications not only take up disk space but can also run in the background, slowing down your system. Uninstalling them helps optimize the system:\n<\/p>\n\n\n\n Tip<\/strong>: On Windows, you can use third-party software like Revo Uninstaller<\/strong> for a complete uninstallation. On macOS, if you want to delete leftover configuration files, use a tool like AppCleaner<\/strong>.<\/p>\n<\/blockquote>\n\n\n\n Browsers like Chrome, Firefox, and Edge often store a lot of cache and cookie data.\n<\/p>\n\n\n\n If you want to save time and automate the cleanup process, you can use dedicated software. These tools help delete temporary files, clear cache, optimize the registry (Windows), completely uninstall software, and even optimize system startup.\n<\/p>\n\n\n Some popular options:<\/strong><\/p>\n\n\n\n Note<\/strong><\/p>\n\n\n\n On HDDs, data can become fragmented, causing the read\/write head to move more, which slows down access speeds. Defragmentation<\/strong> rearranges the data to improve read\/write performance.<\/p>\n\n\n\n How to do it on Windows:<\/p>\n\n\n\n Note:<\/strong><\/em><\/p>\n\n\n\n System Restore saves system snapshots, but if left at the default settings, they can take up several GBs of space.\n<\/p>\n\n\n\n Note<\/strong>: You should only reduce the size, not disable it completely, to ensure you can still restore the system if needed.<\/p>\n\n\n\n 9.1 Clean your computer regularly<\/strong><\/p>\n\n\n\n Dust buildup in the cooling fan, vents, and keyboard not only causes the computer to overheat but also reduces performance and shortens the lifespan of components. You should clean it regularly:\n<\/p>\n\n\n\n When cleaning, turn off the machine, unplug the power source, use compressed air or a soft brush to remove dust, and wipe the screen and keyboard with a microfiber cloth. For desktop PCs, you can open the case for a more thorough cleaning and replace the thermal paste on the CPU\/GPU every 1\u20132 years.\n<\/p>\n\n\n\n 9.2 Update the operating system and drivers<\/strong><\/p>\n\n\n\n Always keep Windows\/macOS and drivers for graphics cards, audio, network, etc. up to date to ensure optimal performance and security patches.\n<\/p>\n\n\n\n 9.3 Manage startup programs<\/strong><\/p>\n\n\n\n Disable unnecessary startup programs to shorten boot time and save RAM.\n<\/p>\n\n\n\n 9.4 Upgrade hardware<\/strong><\/p>\n\n\n\n 9.5 Protect against viruses and malware<\/strong><\/p>\n\n\n\n 9.6 Optimize battery (laptop)<\/strong><\/p>\n\n\n\n Cleaning up junk files on your computer is an important habit that helps extend the device\u2019s lifespan and ensures stable performance during use. With the above steps, you can safely and effectively clean your system without needing advanced technical knowledge. Maintain this regularly (weekly or monthly) to keep your machine running smoothly.\n<\/p>\n\n\n\n If you are using your computer for work, study, or gaming, maintaining a clean and optimized system will save time and prevent many unexpected errors.\n<\/p>\n","protected":false},"excerpt":{"rendered":" Using a computer for a long time often leads to slow performance, full storage, or system…<\/p>\n","protected":false},"author":1,"featured_media":1164,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"googlesitekit_rrm_CAowieHDDA:productID":"","footnotes":""},"categories":[54],"tags":[],"class_list":["post-1292","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-computers-software"],"_links":{"self":[{"href":"https:\/\/kienthucmo.com\/en\/wp-json\/wp\/v2\/posts\/1292","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/kienthucmo.com\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/kienthucmo.com\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/kienthucmo.com\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/kienthucmo.com\/en\/wp-json\/wp\/v2\/comments?post=1292"}],"version-history":[{"count":26,"href":"https:\/\/kienthucmo.com\/en\/wp-json\/wp\/v2\/posts\/1292\/revisions"}],"predecessor-version":[{"id":2574,"href":"https:\/\/kienthucmo.com\/en\/wp-json\/wp\/v2\/posts\/1292\/revisions\/2574"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/kienthucmo.com\/en\/wp-json\/wp\/v2\/media\/1164"}],"wp:attachment":[{"href":"https:\/\/kienthucmo.com\/en\/wp-json\/wp\/v2\/media?parent=1292"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/kienthucmo.com\/en\/wp-json\/wp\/v2\/categories?post=1292"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/kienthucmo.com\/en\/wp-json\/wp\/v2\/tags?post=1292"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}H\u1ec7 \u0111i\u1ec1u h\u00e0nh<\/th> C\u00e1ch th\u1ef1c hi\u1ec7n<\/th> C\u00e1c b\u01b0\u1edbc chi ti\u1ebft<\/th> M\u1eb9o \/ L\u01b0u \u00fd<\/th><\/tr><\/thead> Windows<\/strong><\/td> Disk Cleanup (all versions)<\/td> 1.
