Get JV16 Power Tools, and you won't need to keep re-installing.
Before I ran all the tests, my PC took ages to shut down (around 5 minutes), and I had to manually move my mouse over the task bar to get programs to disappear.
Ran the registry cleaner though within Power Tools, and suddenly, it shuts down on cue every time, first time, with PC health/Registry health now at 100%
It's not free, but it's got a pretty long trial. I suggest you all give it a go
It has honestly sped up my computer 10 fold.
I understand though if you want to clean up programs/software locations etc, because they have gotten a bit messy though
