I recently cleaned my registry using "TweakNow" and now Windows Vista Security is not detecting McAfee. Everything is functioning as normal, but the little red icon in my taskbar reminding me that I somehow lack a virus scanner is annoying me. Any suggestions? I tried restoring the things TweakNow removed, but Vista still isn’t detecting McAfee.

I have a dell inspiron 1520 laptop its about 2 yrs old now when it boots up i get an error sayin windows failed to start due to a recent hardware or software problem and i get the option of lauch startup repair or start windows normally when I start it normally the screen blinks blue then it goes black and reboots

So, I’m trying to clean up every non-essential program from my computer to free up space. When I open my hard drive through "My Computer", my Windows file is using over 35 gigs of space. When I open the actual Windows folder and combine all the files (including Hidden), they total around 4 gigs of space, which I think isn’t too far off the normal mark. So it would seem that Windows XP is just stealing squirreling away about 30 gigs of needed disc space.

Here’s what I’ve tried so far:

– Removing all alloted space for Recycle Bin
– Completely turning off System Restore options
– Running CCleaner, Wise Disk/Registry Cleaner, and the regular old Disk Cleanup and Disk Defragmenter.
– Clearing out all cookies, temp folders, and logs.

I’m not sure how to thank those who answer, so I’ll do it ahead of time. THANK YOU… if anyone has any ideas, please let me know.
Ok, thanks guys for responding. I’ll try your suggestions. Just to be clear, I’m opening My Computer, then clicking once on my hard drive. It tells me I have 45 gigs of used space, when I then open my hard drive, I right click on the Windows folder, then click Properties. The folder properties display tells me 35 gigs are being used. When I then open the Windows folder and select all the contents, they only total to about 4 gigs.
