think it is about not enough space on a disc. Im not sure what is the
difference is between disc C and D. I have gotten VIRUSES cause my laptop is
not up to date. This problem has been going on for awhile... I have
unistalled many programs, but none seem to be from disc D. Everything is from
C. I tried opening disc D and it recommends me not to open it.
I have thousands of importand and recommonded updates that have faild.
On my Disc D i have 1.50GB free space and 11.9GB total spaced used
On my Disc C i have 159GB free space and total spaced used 220GB
They are dateing back to :

Disk D is most likely your restore disk which will restore your C drive to
the original factory install

Click Start, click Run, click Browse, locate the file that you saved and

Add the /wuforce switch to the end of the run command, and then click OK.
For example, the run command may appear as the following:
"C:\WindowsUpdateAgent30-x86.exe" /wuforce
Click Run.

Follow the steps to complete the wizard.

Important

To reinstall Windows Update Agent - download the relevant file from one of
the links provided above and save it to a drive where Vista is not loaded
because the file cannot be launched directly from the system root directory.

Click Start, click Run, type: "D:\WindowsUpdateAgent30-x86.exe /wuforce"
(without quotations) and then press Enter to install the Windows Update
engine.

Note: There is a space between "D:\WindowsUpdateAgent30-x86.exe" and
"/wuforce"

D: is the drive where Windows is not installed (ie a flash drive or a 2nd
hard drive etc)
