GHacks has quite a cool tip for speeding up Windows. Windows stores the temp folder in the same drive where it is installed by default. You can change the temp folder location to improve the performance of Windows. To change the location of temp folder, create a new folder in any other drive except for the Windows drive. Then right click My Computer –> Properties –> Advanced –> Environment Variables –> select temp variable and then click edit. Change the variable value to the folder path you have just created. Click Ok. Now select tmp variable and then click edit. Change the variable value to the folder you want the temporary files to go to.
Now everything is set to go. You should restart your computer for the changes to take effect. Delete the old temporary folders after restarting.
