Run cmd.exe as an administrator, open a command line window, and then run: powercfg -h off. Note that the hidden file of hiberfil.sys left by disk C can be directly removed and deleted.

Set virtual memory

Windows systems, including Win7 and Win8, have a default virtual memory of 0.5 times the size of 65438+ physical memory, which is used as a paging exchange file. If the system manages the size, then this volume will change automatically, and it will often get bigger and bigger. If the physical memory is less, only 5 12m or 1g, you can choose to keep this file.

If you keep this file, it is recommended to put it in another partition instead of the C disk (system disk), otherwise you still need to delete it manually when making Ghost or other backups. It is suggested that the size must be specified, that is, 1.5 times the physical memory size of Ram.

Delete temporary files generated by the application.

Some temporary files generated by program installation and operation can be completely deleted. After a long time, there is really a lot of garbage. These files are usually stored in the windows\temp folder and the temp folder of the user folder.

Cleaning method: directly delete all files in folders c:\windows\temp, C:\ProgramData\TEMP and C:\Users\ User name \AppData\Local\Temp.
