hi mate,
Re "C:\Windows\winsxs\ and rename the pending.xml file to
pending.bak"
Easiest ways are:
on keyboard press the "Windows logo" key and press "E" at the same time, should bring up your Explorer window (which will enable you to explore/browse your files and directories)
or
Click on start then select run and type in "explorer"
Either way you should have an explorer window now.
2. Navigate to Windows\winsxs\ and look for pending.xml pressing 'p' will take you to files beginning with p. If your computer has extensions turned off you will only see the file called Pending maybe with a file descriptor as XML file.
Right click (right mouse button!) on the file and select rename. Rename as instructed, hit enter or click away from the file and it will be renamed.
Good luck
