How to remove a certificate Store added by makecert

I accidentally created a store called Personal and wanted to get rid of it (of course). Two personal stores to look for ughhh. Anyways, I added a certificate that I had created to that store, copied the thumbprint (and removed the spaces) and then searched the registry for the thumbprint. I discovered I could make them go away by deleting the key (in my case Personal) at [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SystemCertificates\Personal] (if in the local machine) or at [HKEY_CURRENT_USER\Software\Microsoft\SystemCertificates\Personal] is in current user. I knew that it wasn't the other one called Personal because the real personal store is actually stored as My.

EDIT: I had to remove a few other keys to solve this but basically search carefully and examine each entry that matches what you are trying to get rid of. For each match, export to a reg file and then delete and test.

Read this and add-type with c# code with pinvoke (already done!) of crypt32.dll

Use a PowerShell cmdlet:
