Hiya Elizabeth,
I get an error message when trying to copy this file saying " Cannot copy usp10: it is being used by another person or program. Close any program that might be using the file and try again"
I have reregistered these but still no change
regsvr32 jscript.dll
regsvr32 nusrmgr.cpl
regsvr32 /i mshtml.dll
regsvr32 themeui.dll
regsvr32 vbscript.dll
I now have my sky drive account and will copy the sysdm.cpl file to it later as I have to go to hosptital soon and wanted to try the other sugestions to see if they would remedy the problem.
I will also try the safe mode boot up and report back how it worked
Regards
Phil
