Hi Mark,
There are three options you can do this:
1. Go to
System Restore and choose a date when the system is working properly say a few days before you accidentally deleted your system fonts. Just follow the process till you are satisfied that the fonts you need are appropriately restored.
2. Your fonts are stored in c:\windows\fonts. If you can find a copy of the missing fonts on another computer you should be able to just copy them over to the correct folder. If they are system fonts you may need to reboot.
3. As a last resort, you can do an 'in-place repair.' You can boot from the CD/DVD as you were doing a fresh install, when prompted click the 'repair' option. That should get you back on track without having to re-install your programs and settings although it will not be without disruption. I repeat only use this last option when all else fails.
Hope this helps.
Best regards,
Grace
