I want a program that make my PC much faster that can clean and fix everything NOTE: my current OS is Win 8.1 Enterprise x64
Unless your computer is years old and never had any utility cleaner software used on it, I doubt there is any software to make a machine "much faster". I use CCleaner and it is safe at the default settings, but even when it has removed 100's of benign registry entries, I don't notice much difference. What hardware are you using? The best thing (IMOH) to make a machine much faster is getting your OS on a SSD. Boot times can drop from 2-3 minutes to 10-30 seconds. Lots of clips on YouTube demonstrating the improvement. SSD prices are getter better all the time and 120GB is plenty for your OS.

CCleaner is not that great on win 8.1 I have used uncleaner by joshcell (MDL) and it is good. For faster PC, get a SSD if you do not already have one.
It won't cost you anything to try CCleaner. As for adding ram, you don't state what hardware is used. And no offense, but the term "fix everything" is vague. Bad hard drive? Virus/malware?
If I could Only make One Improvement to increase performance do yourself a favor and get a SSD drive! plus the prices are coming down as well..DP
You can buy all the cleaning software but then a far better solution is to simply buy a SSD. I would rate buying a SSD as important than buying a good CPU, RAM. In fact, a SSD itself vastly improves performance of the entire system or breathes new life into a tired old system.
No need to yell. Why spend 800 bucks when 200-300 will fit most needs. Upgraded a friends Laptop (mobile i7 something with 8GB RAM) with a 128 GB SSD. machine is flying with Win 8.1.1 . All software claiming to speed-up your PC is mostly 'mumbo jumbo' and in best case harmless. Otherwise the nightmare ends with a fresh install .
Nope, SSD is all you need...If his PC can support x64 the processor is probably already fast enough I speak from experience, I have a 2008 computer with core2, 4gb of ram to which I added an ssd. (Pretty dang fast)
There are some people who say that a SSD should not be partitioned. That might be fine when you are living with say 64-128 or even a 256 GB. But suppose you have only hard disk slot (eg a laptop) and you have the money to buy a ~1TB SSD (which is roundabout the max these days). Obviously, you would not bought a 1 TB SSD for only C:. You would want some partitions for data, music, etc. What is the current, accepted wisdom on SSD partitioning. I think it is OK, and the old advise of not partition must be a hangover of the days of low cap SSDs.
