You're not the only one: http://thedailyreviewer.com/xphelp/view/net-framework-v114322-cannot-hibernate-1011809122 is the same complaint from someone else.
Unless you really need these update (that would be a problem) I'd just uninstall them from the $NTUninstall folder in your Windows account and check if hibernate works again. Then use Internet Explorer and do Tools>Windowsupdate and tell them to skip these updates in the future. If you forget this last step, they'll come back automatically!
It might be this problem solved in SP3. Why didn't you yet update? Both my netbook and 2 PC's run quite well with it. So the first thing after the 2 above would be to download and install SP3 and then these 2 updates again to see if it makes a difference.
Thanks for the warning anyway. I use hibernate on both my netbook and on this desktop, so I'll pay some attention to these updates. Do you now the KB-numbers?
I have a Netbook what has XP sp2 installed. Don't use it just once in a while. There was an update from Microsoft and now my Netbook will not hibernate.
It tells me to shut.... netframework v1.1.4322.... down. Not sure what update it is but there are 2 on 10/10.
