After a long period of using your computer, it tends to be slower than usual; this is due to memory cache inability to flush away unused memory from the RAM. Restarting the computer is an option but not ideal if you’re in a hurry. Flushing the memory via a command is possibly the better option, here is a step by step tutorial on how to go about creating a shortcut for this process.
Right click and create ‘Shortcut’
Copy and paste this code – %windir%\system32\rundll32.exe advapi32.dll,ProcessIdleTasks
Rename the file; there you go, double click the file whenever you want to flush your computer’s memory.
