Vista - Remote Desktop and Services does not appear

Dear All, I installed trial version of PC wash in my computer running Vista x64 Home Edition. during scanning it asked to me disable some services, so i disabled them and then some menus were hidden from me. then i uninstalled the software but still those thing r disabled or completly not appearing.
as an example, Remote Desktop Connection, Services, Component Services, Disk Defrag, Schedule, Disk Clean up and much features are not appearing in accessories menu.
I think i disabled services which caused this, can any one help me please how to enable those services again?

Are you able to System Restore to a date before you installed the program?

Well, after installing that software i have installed other softwares and i have alots of staff in my computer since installing that software.
if i restore than all those program will be uninstalled, which i dont want?
I find only service which i had disabled using that software "Security Center". this service was also disabled, I enabled it and its running, but others i m not able to find?
let me mention some thing. if I write "mstsc" in run then i can run Remote Desktop Connection and the same thing for others. but i can't see them in Accessories.
