Cumulative update KB5001330 fails to install

ERA88 Hello, I wanted to update my situation, as I was finally able to successfully install the KB5001330 update late last night.  As I posted, earlier, I had tried multiple time (4 or more I think) to install this update, and each time it failed at the very end.  I was also unable to pause updates for 7 days (it was greyed out), so the update kept trying to install each time I did a restart.  My Dell Inspiron laptop was constantly running at 100% disk utilization in Task Manager, making everything I did on the laptop very slow.  In an effort to fix this yesterday, I tried many things, including disabling Windows Search and SysMain (previously called Superfetch), changing battery performance to Best Performance, changing minimum and maximum processor state to 100% (in control panel/power options/change advance power settings/processer power management.  I also turned off my iCloud picture syncing.  None of these things seemed to improve the 100% disk utilization.

However, at some point during the day I received a pop up notification that my system needed to restart to install an update.  In all of the previous times attempting to install this update, I had never received this message, and I don't know what prompted it this time.  Maybe the update was running in the background the whole time and finally completed, who knows?  So, I went to restart, and sure enough, there was the option in Start/Power to update and restart, which had also not been there before.  I made sure my files were backed up, and then I did the restart.  The restart went through the process with the blue screen saying that updates were being installed, and it took about 20 minutes, then came up to a black screen for several minutes.  Finally the sign-in screen appeared and I logged in, went to Windows Update, and it said that the update was successfully installed.  I have no idea if any of the changes I did was the thing that finally enabled the update.  Once my laptop was back up and running, it was still at 100% disk utilization.  I turned Windows Search back on, which started the indexing process.  I let that run, it completed, and after about 30 minutes my disk utilization went back to normal (4-5%).  Also, the option to pause updates for 7 days was enabled, so I have done that to allow my machine to stabilize.  I have not rolled back any of the other changes I did (SysMain, etc.).  I hope that this information helps others to resolve their issues.
