Hello
I have upgraded to Windows 11 Pro on two different laptops, and both have the same issue with indexing. It is painfully slow and then usually resets itself after a couple of weeks.
Both PCs are high-end laptops with Core i9 mobile CPUs (1 x 6 core and the other 8 core). Both run 2 x NVMe 1TB drives. Both have 64GB RAM.
Both run MS Office and I use Outlook for email connected to same IMAP accounts on both. My docs, pics, music and work-related files are all stored on OneDrive and accessed from both PCs (OneDrive is set to keep local copies on both PCs for fast access).
Windows is being asked to index around 250,000 files and 80,000 emails and calendar appts. Windows 10 used to accomplish this task in 6-8 hours max.
Windows 11 takes nearly two days just to index the emails. It can take up to three weeks to index the lot and then some folders simply refuse to be indexed. Then, after a couple more weeks it will eventually lose the lot and indexing has to start from scratch again (on both PCs)
I have tried:
Disabling backoff via registry so indexing never pauses
Only adding one location at a time to let it slowly build up (e.g., add only Outlook and when that finishes add a folder)
Rebuilding the index
Storing the index in different location
Search and Indexing Trouble-shooter
Nothing fixes the issue
Any help appreciated.
Cheers
Mick
Locked Question. This question was migrated from the Microsoft Support Community. You can vote on whether it's helpful, but you can't add comments or replies or follow the question.
I think I asked too soon. Deleting the PluginResourceData key cleared up the error I had stopping the Windows Search service. I wasn't indexing very much better, so I went back and deleted the data in C:\ProgramData\Windows\Search. It's now indexing faster than it has in days... over 25k items in just a few minutes.
My reindex after a rebuilt is also painfully slow. About 215 items indexed overnight. I haven't seen any mention of an error in the application log that I'm seeing if I try to stop or restart the Windows Search service. Anybody else seeing this?

I had the same issue.
After trying everything, I used Procmon and saw that HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Search\PluginResourceData was read continuously...
I decided to stop Search service (before disable the restart) and delete this key
Then after the restart, the speed has dramaticly increased, to return to a normal way !
Not sure about the impact of this change but in case of doubt, you can save regitry settings before.
This seems to have worked, thanks for posting! That registry key was just loaded with **** I mean like a lot so don't know what was going on with it but deleting it had immediate results 23,000 items index in about a minute after waiting for an entire day and got maybe 10,000.
Thank you!
I just did the registry fix once, and it seems to continue working.
