Tortoisesvn cannot display the lock icon

The following information is found in the FAQ on the official website: "You may find that not all of these icons are used on your system. this is because the number of overlays allowed by Windows is limited to 15. windows uses 4 of those, and the remaining 11 can be used by other applications. ...... Locked is only loaded if there are less than 13 overlays already loaded. it falls back to normal if there are not enough slots. that is to say, Windows only releases 11 custom coverage icons for the software. If there is not enough space, SVN will take the initiative to remove its locked icon.

You can modify HKLM \ Software \ Microsoft \ Windows \ CurrentVersion \ Explorer \ shelliconoverlayidentifiers in the Registry to ensure that SVN entries are displayed in advance. This is the solution that does not display SVN icons on the Internet, and it is generally considered effective. Check my registry. It really contains multiple icons brought by the synchronization tool groove, but the svn entry in advance cannot solve my problem. I guess even if SVN entries are prefixed, the lock icon will not be displayed normally, but the lock function is rarely used. As long as you can see the check mark, exclamation mark and other icons, it will be considered normal. Delete all groove's contents and restart assumer.exe. The lock will be displayed normally.
The registry cannot be deleted from one machine, and it is very troublesome to uninstall Groove. Therefore, a bat tool is used to delete the Registry in batches, for example, "Reg Delete" HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion \ Explorer \ shelliconoverlayidentifiers \ offline files "/F", whose name is recover_svn_icon.bat. After installing tsvn, run this script.
