e anu po ba processor mo? kung 64 bit processor mo at naka install na O.s ay 32 bit pede mo i upgrade...pero kung 32 bit lang procie mo di po pwede
para malaman mo kung anung type ng processor mo..
Method 1
press mo lang ng WINDOWS LOGO + R tapos type mo msinfo32.exe tinan mo yung processor at system type kung X86 ibig sabigin 32 bit yan pag X64 64 bit yan...

Method 2...
Go to Start -> Right click on Computer -> Click Properties. Click on Windows Experience Index.
Click mo lang yung View and Print detailed performance and system information at makikita mo na ang info ng procie


Method 3
Windows Logo + R type mo regedit
Browse to HKEY_LOCAL_MACHINE\HARDWARE\DESCRIPTION\System\CentralProcessor\0
From ProcessorNameString you will be able to see the name of your processor and from Identifier you will see the family of the processor and if it has 64 then it is 64-bit capable
