go to repair (press F8 immediately after starting and select first choice), then go to command prompt from repair window. The same window can be found via Vista installation DVD.
Then copy
x:\Windows\WinSxS\manifests\x86_microsoft.windows.common-controls_6595b64144ccf1df_6.0.6000.16386_none_5d07289e07e1d100.manifest
to
C:\Windows\WinSxS\manifests\x86_microsoft.windows.common-controls_6595b64144ccf1df_6.0.6000.16386_none_5d07289e07e1d100.manifest

restart and wait a bit.
