Computer maintenance is the practice of keeping computers in a good state of repair. A computer containing accumulated dust and debris may not run properly.
Dust and debris will accumulate as a result of air cooling. Any filters used to mitigate this need regular service and changes. If the cooling is not filtered then regular computer cleaning may prevent short circuits and overheating.
Operating-system files such as the Windows registry may require maintenance. A utility such as a registry cleaner may be used for this. Also inbuilt Disk defragmenter will also help.
Software packages and operating systems may require regular updates to correct software bugs and to address security weaknesses.
