Firstly I would ask why your computer crashes so often, (if it is often), and why you feel it is necessary to re-install the OS everythime it crashes, rather than identifying the problem and solving it without having to resort to a re-install.
Perhaps these crashes are viruse/spyware related? If so, you could beef up your anti-malware defences and protect your system better. Bob Proffitt, another Moderator here, has produced this list;
of anti-malware products, all free, that would help. I would just add to that list the need for a stronger firewall rather than the Windows Firewall, such as ZoneAlarm, also free.
Also, I would ad Ewido AntiSpyware, a later product, from http://www.ewido.net
That said, it is possible to slipstream your OS CD's with SP2 and other updates into another CD, but generally only if the OS on your computer is not an OEM version, (ie, supplied by the manufacturer).
Details for slipstreaming here;
There are methods for slipstreaming OEM versions, eg a Dell, as shown here;
The article says this should apply to any OEM OS, but I have no knowledge of that.
I hope this helps.
I am using windows xp professional.
My query is this.
Whenever the system crashes and I am forced to reinstall the OS and Sp2, I have to necessarily connect to the net and update all the latest critical updates, patches etc.,
This invariably results in a cumulative download of 200/ 300 Mb with a couple of restarts.
Is there a way to make a copy of these patches and SLIPSTREAM into a consolidated updated CD so that at the time of reinstallation you can get the system back to the latest downloaded updates ?
make a backup of all the updates in a seperate folder and ensure the updation takes place in the same sequence as the release of these updates?
