If you are running out of room o your SSD you can free up some space by moving the Pagefile.sys file to your 2nd drive (if you have a 2nd drive) These instructions are for Windows 8.1, Windows 7 is very similiar.
Click on the Start Button and right click on THIS PC (or COMPUTER) and select PROPERTIES
Click on ADVANCED SYSTEM SETTINGS
Click on the ADVANCED TAB and then under PERFORMANCE click on SETTINGS.
Under VIRTUAL MEMORY click on CHANGE
The above Windows shows that Windows automatically manages the paging file and it is on Drive C: (system managed"
Uncheck AUTOMATICALLY MANAGE PAGING FILE SIZE FOR ALL DRIVES
click on Drive C: and then check NO PAGING FILE and then click on SET as in the above example.
Now click on another drive, in this example I am using Drive E:
and change that to SYSTEM MANAGED SIZE and click on SET
Click OK and then Reboot your computer and you should find the pagefile.sys is moved and you have a little bit more room on your main C: drive.
