Hello
Welcome to the Autodesk/AutoCAD Forums !
I appreciate your question/topic which is very verbose !?
Q1) Which Windows exactly : Win Seven 32 or 64 bits ?
Q2) ACAD LT 2010 with which SP/Update ?
Q3) Have you installed the SP 2 for ACAD LT 2010 ?
Q4) Have you the problem : Always or only with ONE or a Few DWGs ?
If problem with ONE or a Few DWGs, please could you open them in RECOVER Mode and then Resave them and then ReTest ...
Q5) Are you running your ACAD LT 2010 as Local Admin ?

Hello
I don't like this Info >>>
Q4) Have you the problem : Always or only with ONE or a Few DWGs ?
[JMc] Problem just started yesterday - occurs on startup - even when opening Autocad LT without opening a specific drawing
<<<
I imagine that you have "Automatic Windows Update" ON ?
Can you restore your Win Seven to a date before "yesterday" ??

Hello
So you have a Restore Point "2 days ago" so maybe you have install something 2 days ago !?
If YES, which software ?
