Good morning,
Several weeks ago I received an update for Microsoft .Net Framework 3.5. Unfortunately when WinPatrol asked permission to accept these new updates, I mistakenly clicked no.
I have looked for ways to undo my mistake: I checked my list of installed updates and found 2 Hotfixes for .Net Framework 3.5, KB953595 and KB958484. Also the Firefox addons window shows a new addition: .Net Framework Assistant 1.0. I have searched for the appropriate updates on the Microsoft Update website, but only became lost and confused.
I believe these .Net Framework updates are important for my computer and should be reinstalled correctly. However, I do not know which updates to uninstall nor the correct .Net update to reinstall.
Will someone please advise?
Thank you,
Vaesther
