I hate how Vista+ are so good at protecting Windows. I just ran a bunch of the highest rated "optimizers" (disk cleaners, registry cleaners, etc.) including the ones I shared above on my laptop while playing Sanctum 2. Not a single one broke anything from what I can tell. Plus they all mostly agreed on what was "to be fixed" except for minor things.
Ahh for the days of 98 or XP losing key information that some random program flagged as unnecessary. Or when every program wanted to redo everything so they'd just increase the errors all the others found.
The Wise Cleaners (Disk and Registry) and Auslogics Registry stuff seem pretty decent and unobtrusive. If anyone wants to toy with something beyond CCleaner. Although Auslogics own Registry Cleaner disagrees with their own Disk Defrag in the "post-usage FULL SYSTEM SCAN", which then disagrees with the Registry Cleaner's opinion on disk fragmentation. Both suggest I buy their paid software suite. Which is kinda odd, you'd think they'd agree on how many errors are found...
IOBit's Advanced SystemCare is something that would totally get some self-declared poweruser (who never games and just uses Office and the internet, maybe rips CDs or converts audio/video) to use it constantly. Even though it likes to install itself all over the system and into browsers and refuses to share its details completely upfront ala CCleaner or Auslogics or Wise. I can see why it has like a five star rating on every site and was a PICK OF THE YEAR on a bunch of sites/magazine.
I think if I'm helping someone I might stick to keeping CCleaner portable and Auslogics Disk Defrag portable still on my one usb stick. Maybe I'll stick the Auslogics (because it scans everything not just the "extra safe" stuff CCleaner does) and Wise (because it has lots of options and also offers an easy way to get rid of things like Chinese language, Windows installer cache, etc. to free up space) things on there if they also have portable versions. A lot of these grander things I don't exactly trust. (Even if they don't seem to have fucked up my laptop and did clean another 400MB off and probably 150 more registry entries.)
Advanced SystemCare improved my Laptop from a half smile to a FULL SMILE. I kinda want to run on it something horrible just to see the FULL FROWN. Too bad all the females I know seem to have moved onto iPads or whatever instead of fucking up their laptops every six months.
Scary fact: One of them fucked up their Windows so hard I couldn't figure out what the hell to do with it, it would take like ten minutes to load FireFox from scratch so she just left it open which I'm sure was helping whatever malware just wreck up the joint. They of course didn't have the recovery disk. (Although a shocking number of people I know have kept it around, and barely ever have any data, a couple I was able to back up everything onto a 4GB flash drive lol...it was always fun to go back into a fresh XP and see all the windows updates offered) I asked her what exactly she thought she'd need to use it every day for, facebook, music, etc. So I wiped it out and installed Ubuntu and showed her each of the equivalents. She didn't really seem to get it except FireFox was the same, and I kinda gave up thinking at least she had that. Like two years later she gets a new laptop finally and asks me to put it how it was aka with all the Ubuntu equivalents of Windows stuff.
Scarier Fact: First time I saw her Windows laptop she had like seven months of uninstalled Windows Updates. For whatever reason she kept up to date on the Ubuntu updates because she checked them regularly. (Helps that's how you update every program I suppose.)
Scariest Fact: She learned to type "ubuntu [whatever she wanted]" into google and eventually found the software center due to this.
