HARD DRIVE CLEANER 2.345 CLEANING registry & back up it

HDCLEANER 2.345 The registry cleaner included is not a full-fledged registry cleaner, rather it simply searches for invalid references to files in your registry. Which registries do you know to delete? How does one make up a back up of the registry ones that come up to delete Backing up registry if you don't have a floppy dirve but have a cd burner using roxio 6.0 cd & dvd creator software. I thought i would be able to burn a cd to back up registry using Cd data option or creator classic option.The option to back up the registry before deleteing with the use of only using a floppy drive is the only option mentionedd . My floppy drive was removed by my vendor But I'm not sure how to do this being a newbie to back up the registry with a CD burner. Thanks appreciate help

 

1) you could backup registry yourself and it is not hard at all but a manual FULL registry backup could be rather large. For example:
The multimedia system I have with dual DVD burners, 160GB HD-2 partitions (65% used overall), C:\Program Files folder has a total of 101 sub-folders and roughly 76 programs installed (showing in Add-Remove Programs list without counting the Windows security patches, updates, etc.) And when I did a:
START > RUN > regedit > OK (registry editor opens up) > right-click on 'My Computer' (on the very top) > Export (name the backup file, choose location) > click on SAVE. When it was completed the size of the file was a over 48MB! Assuming you would have about 1/3 as many applications yours could still hover around 20MBs, once created using the CD Burner software and a preferably a CD-RW media burn the file. But you could leave it directly on the C drive for easy access and you wouldn't need to burn it. Also LastKnownGoodConfiguration option could resolve most newly installed device driver/ registry problems as well.
RegCleaner is a somewhat manual registry cleaning but it makes the entries more recognizeable, for Windows XP, couple of decent & free registry cleaners I know and used are: WT RegCleanerXP and RegSupreme.
I personally prefer, use and like V-COM's System Utilities...the registry cleaning/registry defragging utilities that comes integrated is the most complete and detailed one I have seen so far, it finds missing or invalid entries and if it finds alternative links it lists all available/applicable alternative pointers/files for you to choose or delete. It warns you with color designators as to what files are safe to go, which ones could be needed and which ones are presumably system critical...
No matter what utility you use or manualy modifications you plan to make, always and always BACKup the registry and even your personal files...just in case.
Hope this info helped a bit.
