Apple Macbook Mid 2010 Ram Upgrade & Equipment & Windows Compatibility Now I have 2 gb (1gb x2) as standard I want to upgrade it. "Hi-Level 4GB 1066MHz DDR3 Notebook Ram (HLV-SOPC8500D3/4G)" is it okay to be upgraded? and after I replaced that one with one of my standard ram should I dislocate the other one? I mean can I use 5 gb ram (4+1) ? 

And my second question is about removing process. Which equipments I'll need? If it is not obligatory I don't want to buy as a kit. Could anybody name these equipments I need?

Finally, will 16 gb or 8 gb RAM work for windows (dual-boot) properly? (LAST QUESTION DID NOT ANSWERED YET)
Your Macbook 2010 will be fine if you buy 2x8gb of 1066mHz DDR3. You will dual boot without issues. Correct ram speed is important, see my answer to a similar question here about possible issues with faster ram.

You will need Philips #00 screw to upgrade your memory. There is also a great guide at iFixit.
