Step 2, transfer the virtual memory (the physical memory is larger than 4G, which can be turned off). Computer-Right Click-Properties-Turn off Hibernation. Win key +r to open the running input "powercfg -h off" double quotation marks, do not copy.
Step 3, delete the recovery folder under the root directory of drive C, which is mainly the system recovery point and is also used by F8 when entering recovery. There is also recovery under the system.
The fourth step is to simplify the boot directory under disk C, which is the font displayed at startup and the folder for startup items and memory detection. Look at the picture, don't delete it wrong.
Step 5, delete the folders in C:\Users except your own users (I only use my computer, so I can do this. If your computer has many users, don't delete it)
Step six, streamline the font folder. Use Rubik's Cube Cleaner to clean up the security, or delete it manually.
Step 7, delete the folder C:\Windows\Help (novice user's manual), delete the input method that comes with the C:\Windows\IME system (it can be deleted by input methods from sogou and third parties), delete C:\Windows\Media (startup sound, shutdown sound and various sounds) and delete C:\Windows\Performance (folder of system rating-experience index).
Delete the input method that comes with the C:\Windows\System32\IME system (it can be deleted by the input methods of sogou and third parties). Delete all folders with "-"in C:\Windows\System32 (except zh-CN and en-)
The following two folders occupy the largest first folder of drive C: \Windows\winsxs. This folder is used by the system to store various versions of Windows components, thus reducing the configuration problem (DLL hell) caused by dynamic link libraries (DLLs). In other words, it is very important to the system.
