I just reformatted a Dell OptiPlex 380
Windows 7 SP1, I'm trying to update with Microsoft Updates but it just stays stuck on "Checking for updates"
If I look at history the only updates are: Windows Defender KB915597 and Windows update agent 7.6.76.00.320
Reboot again and the updates should work. It still might take a while. From the original installs there are upwards of 200 updates
just in the first pass. Be patient and let it run.
If the above doesn't work download wsus offline updater. Pull down all your windows 7 updates, and any other updates you may want to choose, install all with wsus offline updater. Your updates will work after that.
after it reboots download and run the update patch here: https://support.microsoft.com/en-us/kb/3102810
