Slowness can cause due to programs running on system tray.. First try to remove them from system tray..
(1)Previously in windows 7 to remove startup running application you just need to go to msconfig utility but in windows 8 it was transferred to task manager.. so just open task manager and go to start up tab an disable newly installed unnessary startup programs .. reboot and see...
(2)If it is still slow you need to uninstall all apps you installed and check..
After uninstalling also if it is slow need to go for system refresh -- a new feature in windows 8
Just open control panel (shortcut to open control panel is just press windows key and R together and type control and hit enter) and go to this path .. Control Panel\All Control Panel Items\Recovery and go ahead with refresh you pc option..
This will open a metro interface and scroll down a little bit and select system refresh..
Then it will give you a warning and just continue...This will indicate what will be kept after refreshing..
That's it.. Before go in to system refresh you should know about it.. This option will remove all apps you installed and settings system tweaks registry edits.. It will keep factory default windows settings and your personal files..
You can access system refresh at the boot time by using windows installation media or recovery disk ... This may be useful in the event of failure to load to windows due to installation of an application or any other major system instability ..
