That's the answer to "would a registry cleaner speed up my PC". The answer to your last question also is "no", by the way.
Usually, loading a webpage slow is bad indicator of the computer running slow. Usually, it's only an indicator of the Internet connection being slow. But since you have (had?) both a laptop and a desktop connected to the same Internet connection, it's easy to compare.
- If both are abnormally slow loading web pages (turn off the other while testing), there's a good chance it's the connection (but it's possible also you have the same malware on both).
- If only one is slow and the other is 'normal', something is wrong with that one computer. The easiest way to get it back to its original speed then is to get it back to it's original configuration using the recovery disks you made or the Dell recovery partition.
I'm posting my question here because the subject I'm about to ask about I know nothing about. My Dell Vostro 1510 laptop which has Windows Vista Premium 32 bit has been running very slow lately; web pages take forever to download. My DSL service is with AT&T and I have Extreme 6.0 which is supposed to be AT&T's fastest DSL speed.
AT&T has faster speeds called Uverse but I do not have Uverse. Would a registry cleaner(?) help improve my computer's running speed to like it was when it was brand new? I know absolutely nothing about registry cleaners. Are they safe to use on a computer?
