[Answer]Vista SP2

Question：As SP2 contains all the past updates,  then having updated from SP1 to SP2, can I now uninstall all the past security updates since SP1 and upto SP2.
Or does the SP2 automatically uninstall these now redundant updates to free memory space?
Thanks,
Ricky

Answer 1：

Hi Ricky,

 

Thank you for posting your question on Windows Vista Forums.

 

Service Pack 2 only contains updates released after the release of Service Pack 1 and other updates for security, reliability, performance, compatibility etc.

 

If you have installed Service Pack 2 from Windows Update, then the past updates would have not been replaced by Service Pack 2 and only the required updates would have installed on the machine.

 

If you have downloaded the standalone package of Service Pack 2 on the machine and installed it, the update would have replaced the past updates on the machine and only one instance of each update will be installed on the machine.

 

That is the reason why any Service Pack update through Windows Update is less always in size than the update from standalone package as it checks as to what updates/patches are required to be installed and only those are installed on the machine.

 

So, you need not to worry that your machine has redundant copies of the same update. There will be only one copy of each update.

 

Hope the above information helps. Please post back and let us know.

Thanks & Regards
