As you can see, NONE of the MS people give you a direct answer for your direct question, namely, "Constantly on my computer I started to feel a slowdown. When look at the task manager I saw all the processor used %100 by sppsvc.exe. How can I resolve this situation I encountered."
So I, not being in the employ of MS, WILL:
When you first install Windows on your PC, or buy it that way, you are expected to immediately go online to verify your authentic Windows purchase and installation, so that Gates et al may continue making their $Billions. They call it "Activation". You get
15days (as of Win7 in 2014) in which to accomplish this task, even if you are merely testing a system to see if this is the best OS to install on it, or the best OS for its intended user.
Until you perform this "Activation", MS will continue to run this little bit of spyware in the background that checks to see if you've "Activated", and if not, to NAG you until you do, and to slowly slow your system down to a crawl if you go past the 15
days without "Activation", such as might happen if the system sits unused while you are hospitalized for some sort of flesh-eating bacteria...
MS DOESN'T CARE: they merely want their $200 for licensing you to use Windows, or they're not gonna let you use that PC (unless you upgrade to Linux or Mac OSX or whatever else is available)!
BTW, I hope you also know that when you PAY that $200 for Windows to install, you DON'T OWN your copy. In many instances, you can't re-sell it or even transfer it to a replacement computer, or even continue using it on the same computer, should you upgrade
its CPU, motherboard, or other components deemed to indentify the system. It's for THAT computer as it was built at the time you "bought" and installed Windows on it. Anywho, when you plunk down your money for Windows, all you're truly doing is buying a LICENSE
with which to USE it on that single computer for which you bought it. That license then becomes useless if, as happened with XP last month, MS stops supporting it (IOW, closing holes it left in XP -- and assorted other MS software on that system -- thru which
hackers may attack your system.)
And if you're building or setting up a server, you have to buy additional licenses for every user who will access that server!
The good news is that once you do "Activate" your copy, the nasty little trojan/TSR will hopefully disappear, never again to bother you. If it does, delete it and sue MS if it causes your PC to crash unless you allow it to run... Or better yet, buy a Mac.
The OS is free now. And fairly free of viruses and other malware. And quicker, and more intelligent, and comes with real apps out of the box...
