Existe t'il un soft qui fasse une image de la registry avant et apres une install ?

oui, plein !
 
tu as regsnap, sysdiff (directement sur 2000), wininstall...

Sysdiff tourne t'il ss W98 ?

moi j'utilise inctrl5 (de pcmag) pour monitorer l'installe complet des soft (changement dans le registre, dossier, fichier, system ini ....)

je ne pense pas...
 
mais vas faire un tour sur www.telecharger.com, tu en trouveras beaucoup...

 
On peut refaire un script d'install manuel derrière ?

 
non, il ne fait que du monitoring

 
Oui, avec un outil comme Undoreg qui est capable de lire les fichiers générés par Inctrl5, regshot, etc. Je ne l'ai jamais testé personnellement, je ne peux donc dire si c'est efficace.
Voici le readme.txt en anglais qui accompagne Undoreg, le lien pour télécharger est le dernier des URL cités, le fichier fait 53 Kb.
 
Thank you for trying UNDOReg!
 
NOTE: This Win95/98/NT (or higher) freeware program is provided as is and without any guarantees of any kind. It may be freely distributed, but not modified in any way.
 
 
*** DESCRIPTION ***
 
When you install a new program, the installation utility adds new data to your system registry, often UNREMOVED after the uninstallation. You can have a record of exactly what the install program did using:
 
- InCtrl 4.1:
http://www.zdnet.com/pcmag/pctech/ [...] 2.001.html
 
- InCtrl 5:
http://www.zdnet.com/downloads/sto [...] 24,00.html
 
- System Mechanic:
http://www.iolo.com/
 
- RegShot:
http://winice.yeah.net
 
UNDOReg analyzes the report generated by one of these utilities, and deletes referenced registry keys.
 
 
*** USAGE ***
 
Click on "Open Report" and choose a TXT report generated by "InCtrl 4.1 - 5", "System Mechanic Safe Installer" or "RegShot".
Alternatively, create a shortcut to "Undoreg.exe" and put it into your "Windows\SendTo" folder. You can then right-click on any TXT report file and choose:
 
[Send To] --> [Undoreg.exe]
 
 
*** UNINSTALLATION ***
 
Go to control panel add/remove programs, select "UNDOReg" and press the add/remove button. Your system will be completely cleaned.
 
If you like this software, *please* let me know.
