Delete registry keys

Hello all,

I was wondering if some1 can create .reg or batch script, or something, that would delete everything from HKEY_CURRENT_USER/SOFTWARE/Microsoft/Windows/CurrentVersion/Explorer/ComDlg32/CIDSizeMRU, except following keys:
name:             type:
(Default)         reg_sz
0 - 48              reg_binary
MRUListEx     reg_binary

So, everything else, that is in this registry location should get deleted.
Picture attached. A bit small tho :)

Export these keys, first using reg.exe /export, then delete the whole key, then reimport.

Are you planning to delete these keys for all the machines?. Why don't you just export the key (as backup) and delete the unwanted keys from the registry itself?

If you look at the value of the keys, it will be huge data and you will get confuse if you try to export and try to delete.
