Getting rid of unnecessary applications
Once in a while I have to get rid of all the unnecessary applications that I install on my machine either as trialware or demo software and I find PC Decrapifier to be very useful for that.
Decrapifier is an exe and so there is no need to install it and you just click the executable file and run it.
It creates a restore point first but I wouldn't trust that too much and so I usually uninstall a bit at a time and check to see if the machine is still booting and running properly.
There is a commercial version that can also automate itself but I find the free version enough for my needs at the moment>
I am sure there must be other products out there that do a similar job and if I come across one I will try and update this post.
