Unfortunately, the syntax described in "C:\Program Files\jv16 PowerTools 2006\Settings\HistoryCleaner\readme.txt does not support very much.

Case 1
Key=a key string apparently does point to a key, but counts nothing by itself, and removes nothing.

Case 2
If entrynames have the format "prefixN" where prefix is a string and N is a number, then:
Key=a key string apparently does point to a key, counts the entries, and can remove them.
Basevalue=prefix

Case 3
If entrynames have the format "C" where C is a single character and there is a list entry named "name", then:
Key=a key string apparently does point to a key, counts the entries, and can remove them.
Listingvalue=name
There are two bugs:
1. the count is too big (should be 1 less)
2. the "C" entries are removed and backed up correctly, but the "name" entry is also removed and not backed up

The keywords Subkeys=True/False does nothing detectible.

Most of the distributed "samples" in "C:\Program Files\jv16 PowerTools 2006\Settings\HistoryCleaner" do nothing or very little.

Conclusion
The UserAssist items are Case 1. Therefore, the current documentation (and implementation?) of History Cleaner does not support them.

Until History Cleaner is more usable, these lines run from regedit in a batch file remove the UserAssist Count entries:
