I believe that once you select "no paging file" everything that was in the paging file is dropped and a new one started wherever you set it.  I just did both changes at once - relocating the pagefile, rather than moving it.  It just drops the original and begins a new one (and you never get any no pagefile error).  

I have my registry set to clear the pagefile every time I shutdown at night anyway, so it starts anew at each boot and never needs defragging (and doesn't keep data that may be risky).  

Registry Settings System Key: [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management]
Value Name: ClearPageFileAtShutdown
Data Type: REG_DWORD (DWORD Value)
Enable clearing page file at shutdown.....- 

change    ClearPageFileAtShutdown   DWORD value from (0) to (1)

If the Value Name "ClearPageFileAtShutdown doesn't exist, you can just add it.  As always, use the free app. ERUNT to make a fast backup of your registry before making registry changes.  --Anna Summers

Subject: Re: Changing paging file


Just a note to add, I suggest that before placing a paging file on a 
disk, that it be recently de-fragged. If the disk is already has a 
paging file on it (meaning you want to completely de-frag the disk and 
paging file prior to setting a fixed size paging file), then use a two 
step approach. The first step is to set the paging file to none (using 
Anna's basic instructions below, but select the option for no paging 
file). The when asked to reboot (ignore any wanring about not using a 
paging file is not recommended, etc), reboot into safe mode. Run the 
full defrag on the disk, then go back into the advanced system 
properties to set the paging file to the fixed size (same minimum and 
maximum) as Anna describes, and reboot normally.

Using a fixed size paging file (using the same size number for both Initial and Maximum) reduces fragmentation.
