Will do but I have never found any program that makes that claim that actually does so.
I'll report back in a bit.
1st link:
Definite misunderstanding. I was under the impression that you had written two programs that you claimed made these improvements. Looking through the information at the links you posted I see it is just recommendations for using know good software, like CCleaner or known good practices for for reducing unneeded programs.
Some of what you recommend in the first link, having possibly having a small effect on performance, makes the coumpter less useable, at least for me, as well as less attractive to see (desktop background for instance).
Over all, a very good list of suggestions.
2nd link: SysPerf program
Windows defender continually says it's a virus and deletes it, as you said it would. Running it now.
It also makes about 100 registry changes some of which I recognize, most I don't.
You run Disk Cleanup which removes Windows.old thus preventing someone from reverting back to the previous OS. Only a concern until the 30 day mark is hit, as after that it's cleaned up anyway.
You run DISM which is okay but you then delete all existing Event viewer entries. Mostly okay but sometimes this can cause loss of useful information.
Sorry but I don't recommend this one.
