One of the tricks I've used for a long time to speed windows machines up is to boot off a utility disk and delete pagefile.sys swapfile.sys and hiberfil.sys These files are *always* locked by windows and never get defragged and can quickly become the most heavily fragmented and corrupt files on the system.

 

I've done it this way because in my experience setting windows to clear the paging file at shutdown made it take much longer to shut down or reboot.. but this was back in the era of windows 7. Is this still the case in windows 10? and if so is there a utility that will clear the paging file *once* at the next reboot? I do more work remotely now and booting off something else doesn't work very well remotely!

I miss the old days of Windows 3.1 - Windows For Workgroups 3.11 and Norton disk defragger!  Back then, if memory serves me, such would even defrag the swapfile and pagefile.  One way to maybe reach a balance is to "hard-set" page and swap files to a certain minimum/maximum sizes.  I think one source for Windows 7 indicated the virtual memory can be approximately one half of the RAM on the motherboard; however, I'm not sure that would apply to Windows 10.

Virtual Memory Pagefile can be cleared performing the following...
 
Open Local Security Policy, to do this press Windows Key + R together and type secpol.msc
 
In the left pane, Expand Local Policies then Expand Security Options
 
In the Right pane, Scroll to find Shutdown: Clear virtual memory pagefile
 
Double click Shutdown: Clear virtual memory pagefile
 
On the Local Security Setting tab select Enabled, click Apply and Ok
 
Close the Local Security Policy window.
 
Hope this helps
