Windows 7 & Check Disk

I ran Check Disk on someone's Windows 7 installation and they called me saying the operating system is not working right and is acting funny. I haven't seen in person what it is doing but wanted to know if anyone have heard of anything like this, know what it maybe doing, or even know of what can be a remedy? Hindsight is twenty twenty and I am hoping to have something to look for before going over.

 

The only problems that I have been seeing is when the OS is a fake copy, for instance some of those can be controlled with the approppiate settings in control panel; in addition to control viruses I had to change a little my package like the defrag utility. Is working fine here. Find out what the comp is doing.

 

Given the couple who own the unit, it is a legitimate copy from HP. I will be looking at the unit soon.

Can you tell a little more of the 'changes' you had to make?

 

I still use CCleaner, but did not work (for some reason) with W7 Spybot, AdAware and Diskeeper Lite, so I changed to SUPERAntispyware, add Malwarebytes, Advanced SystemCare, AVG 9 and IOBit Defrag utility. And I add that package to any friend that put their computers in my hands.

 

:confused I use cCleaner with W7, 64 bit, and have installed and used it on a number of machines.

 

sorry... this issue was someone accidently hit to full screen IE8 and didn't know they had or how to revert to a normal window... I told them to use the toggle key F11 and they were exstatic it was fixed...
