My sister has recently been receiving some errors concerning .net framework, so I ran windows update as a preliminary measure. It proceeded through steps one and two of the installation process and then asked to be restarted. After being restarted, it came back and said "Configuring updates: Stage 3 of 3". The status reached 100% complete, the computer restarted itself, but then it began "Configuring updates: Stage 3 of 3" all over again. This has been repeating itself cyclically for the past thirty minutes or so. Is there anything I can do?
