Power Options > Power Schemes ... deleted, missing, gone

[Guest]

Some how all my Power management schemes have been deleted and I can't seem
to add or save a new one. How do I add a scheme if all the others have been
removed. FYI... the normal buttons for saving are no longer operable... This
is an advanced question because I know MS has had problems with this for the
past 3 years and haven't fixed it in their package.

Advice offered as is, but this did the trick for myself and someone else,
and so perhaps worth a try

Set a system restore point (in case of errors) then ..........

start > run > regedit

Navigate to
HKEY_CURRENT_USER\Control Panel\PowerCfg\PowerPolicies

Look at the various key listed there eg 10, 11, 12 and see what comes up in
the "Name" value in the right pane
If the key has no "Description" or "Name" value key in the right
pane try exporting / deleting those.
The other Power Schemes should hopefully return.

If you don't have keys with values 0,1,2,3,4,5 then they have been deleted.

There are "backup" copies in
HKEY_USERS\.DEFAULT\Control Panel\PowerCfg\PowerPolicies
which you could try exporting and then modify the .reg file (right-click and
choose edit and change all occurrences of "HKEY_USERS\.DEFAULT" to
"HKEY_CURRENT_USER") and then click on the .reg to import the bits you need
into your current user section
