I found this link about the above error code but when I attempted to delete the .blf and .regtrans-ms files I got a message that it was in use by another process.

Fix Windows Update Error 0x80071a91

Do I need to boot into safemode to delete these files?

Hello and welcome!

Step#1 - FRST Fix
NOTICE: This script was written specifically for this user, for use on that particular machine. Running this on another machine may cause damage to your operating system
1. Please download Farbar Recovery Scan Tool and save it to your Desktop.
Note: You need to run the 64-bit Version so please ensure you download that one.
2. Download attached file and save it to the Desktop.
Note. It's important that both files, FRST64 and fixlist.txt are in the same location or the fix will not work (in this case...the desktop).
3. Run FRST64 by Right-Clicking on the file and choosing Run as administrator.
4. Press the Fix button just once and wait. If for some reason the tool needs a restart, please make sure you let the system restart normally. After that let the tool complete its run.
5. When finished FRST64 will generate a log on the Desktop (Fixlog.txt). Please post the contents of it in your reply.
6. Try updates and if any fail, attach CBS.log.
