Unfortunately after you install this servicing stack update, you cannot uninstall it to revert to an earlier version of servicing stack update.
Try to create new user account as an administrator (it may not help).

How to refresh, reset, or restore your PC
Hi,
As S.Sengupta mentioned, the servicing stack update can not be simply uninstalled since it is required by the system (there's no uninstall option), I have installed the update in my Windows 8.1 system and everything is still functioning fine. We recommend to get latest windows updates.
And Windows updates should not bring additional desktop icons and programs to your system, it is used for system maintance. I suggest you run virus scan in case the system might be infected with malware or virus.
Use system restore to return the system to a previous state with a restore point (I returned to a previous state, it removed the update, maybe you can have a try, but I doubt that the issue you encountered is not related to the update).
Add:
It's recommended to set to install important windows updates automatically, you can also use disk cleanup to release the disk space.
Regards
There are a number of things that could be degrading your system performance. You should open Resource Monitor and post a screenshot showing the processes using the most processor, disk, and memory. It is possible that after installing all of the updates missing for the past year that tiworker.exe is running in the background. This process cleans up your installation following update installation.
Additionally, drivers may have been installed with Windows Update that could be a part of the issue. I would suggest manually checking for the latest available drivers for your system or its devices from the manufacturer.

I am finding it very slow to select something from the taskbar at the bottom of the screen.
It is particularly bad when there are multiple windows (eg. multiple browser windows, or multiple folders open in Windows Explorer), and choosing among them.
I do not remember that update last month, but a colleague tells me that is probably what did it.
