Don't clean the registry unless you know what you are doing.
(register vs. registry - incorrect vs. correct name - tells me you
did not.)
Did you save the 'backup' it asked you to before cleaning it? I
suggest putting that backup back in (find the file, double-click -
merge it back in.) CCleaner is generally harmless - but why take
the chance?
Try the following:
Download, install, run, update and perform a full scan (separately)
with the following two applications (freeware versions are the ones
to use for this):
SuperAntiSpyware
http://www.superantispyware.com/
MalwareBytes
http://www.malwarebytes.com/
After performing a full scan with one and then the other and
removing whatever they both find completely, you may uninstall
these products, if you wish.
Reboot.
Start button --> RUN and type in:
%SystemRoot%\system32\net stop wuauserv
--> Click OK.
Start button --> RUN and type in:
%SystemRoot%\system32\regsvr32 %SystemRoot%\system32\wups2.dll
--> Click OK.
Start button --> RUN and type in:
%SystemRoot%\system32\net start wuauserv
--> Click OK.
Download the latest version of the Windows Update agent from here
(x86):
http://go.microsoft.com/fwlink/?LinkID=91237
... and save it to the root of your C:\ drive. After saving it to
the root of the C:\ drive, do the following:
Close all Internet Explorer windows and other applications.
Start button --> RUN and type in:
%SystemDrive%\windowsupdateagent30-x86.exe /WUFORCE
--> Click OK.
(If asked, select "Run.) --> Click on NEXT --> Select "I agree" and
click on NEXT --> When it finishes installing, click on "Finish"...
Reboot.
Download/Install the latest Windows Installer:
http://www.microsoft.com/downloadS/...6F-60B6-4412-95B9-54D056D6F9F4&displaylang=en
Reboot.
Log on as an user with administrative rights and open Internet
Explorer and visit
http://windowsupdate.microsoft.com/ and select
to do a CUSTOM scan... (Every time you are about to click on
something while at these web pages - first press and hold down the
CTRL key while you click on it. You can release the CTRL key after
clicking each time.)
Once the scan is done, select just _ONE_ of the high priority
updates (deselect any others) and install it.
Reboot again.
If it did work - try the web page again - selecting no more than
3-5 at a time.
The Optional Software updates are generally safe - although I
recommend against the "Windows Search" one. I would completely
avoid the Optional Hardware updates.
Visit your hardware manufacturer's web page (Have a Dell? Got to
Dell's Support web page - downloads and drivers and enter in your
machine's service tag/serial number. Same for the other third-tier
vendors like HP, Lenovo, Gateway, etc.) and get the latest hardware
drivers for each hardware component: motherboard chipset, video
card, network card(s), sound cards, etc.

If you are comfortable with the stability of your system, you can
delete the uninstall files for the patches that Windows XP has
installed...

You can run Disk Cleanup - built into Windows XP - to erase all but
your latest restore point and cleanup even more "loose files"..

You can turn off hibernation if it is on and you don't use it..
When you hibernate your computer, Windows saves the contents of the
system's memory to the hiberfil.sys file. As a result, the size of
the hiberfil.sys file will always equal the amount of physical
memory in your system. If you don't use the hibernate feature and
want to recapture the space that Windows uses for the hiberfil.sys
file, perform the following steps:
- Start the Control Panel Power Options applet (go to Start,
Settings, Control Panel, and click Power Options).
- Select the Hibernate tab, clear the "Enable hibernation" check
box, then click OK; although you might think otherwise, selecting
Never under the "System hibernates" option on the Power Schemes tab
doesn't delete the hiberfil.sys file.
- Windows will remove the "System hibernates" option from the Power
Schemes tab and delete the hiberfil.sys file.
You can control how much space your System Restore can use...
1. Click Start, right-click My Computer, and then click Properties.
2. Click the System Restore tab.
3. Highlight one of your drives (or C: if you only have one) and
click on the "Settings" button.
4. Change the percentage of disk space you wish to allow.. I
suggest moving the slider until you have just about 1GB (1024MB or
close to that...) 5. Click OK.. Then Click OK again.
You can control how much space your Temporary Internet Files can
utilize...
Empty your Temporary Internet Files and shrink the size it stores
to a size between 64MB and 128MB..
- Open ONE copy of Internet Explorer.
- Select TOOLS -> Internet Options.
- Under the General tab in the "Temporary Internet Files" section,
do the following:
- Click on "Delete Cookies" (click OK)
- Click on "Settings" and change the "Amount of disk space to use:"
to something between 64MB and 128MB. (It may be MUCH larger right
now.)
- Click OK.
- Click on "Delete Files" and select to "Delete all offline
contents" (the checkbox) and click OK. (If you had a LOT, this
could take 2-10 minutes or more.)
- Once it is done, click OK, close Internet Explorer, re-open
Internet Explorer.
You can use an application that scans your system for log files and
temporary files and use that to get rid of those:

Those can help you visually discover where all the space is being
used.
In the end - a standard Windows XP installation with all sorts of
extras will not likely be above about 4.5GB to 9GB in size. If you
have more space than that (likely do on a modern machine) and most
of it seems to be used - likely you need to copy *your stuff* off
and/or find a better way to manage it.
After you have done the malware scans and cleanup, the Windows
Updates, updated hardware drivers and freed up space - redo your
defragmentation and perform a CHKDSK as well.
Then return here and give the specifications for your machine. What type
of processor (brand and # of cores and speed) do you
have? What size hard disk drive do you have and how much free
space on how many partitions? How much system memory do you have
and is is being shared with your video card? What type of video
card do you have and how much memory on it? (
