this is a simple way to make yr pc work better than before and delete some useless files .....
there's two folders you can dispense with them (dllcache + i386) .
the first one (dllcache) save a backup copy of system files, so i think we dont need it and we can delete it like that :



and write this :

sfc /cachesize=5

like in the pic :



where will this reduce the size of backup files to the memory system of 508 MB to 5 MB only.

so go to C:\WINDOWS\system32\dllcache





like u see CTLR+A to select all and then click SHIFT+DELETE to erase all

and then we move to the second folder (i386) and delete it .....



and do the same thing u do to the first folder



select it and push SHIFT+DELETE to erase it .... and here we done :)

hope you to benefit this small truc :)

no i test it, it's just a copied files( u can find the original in system32)

dont worry if there were a problem i'll the first one fall in it lol
