Indexer Backoff Not Working - Indexer Isn't Respecting User Activity And Uses Full Resources As If Backoff Is Disabled

Hello everyone, I hope you are doing well.

I have recently found out that there's an issue with my indexer backoff not working properly lately and I'm seeking some assistance. Despite how many times I tried to enable it by going to regedit and setting DisableIndexerBackoff to 0 and going to Group Policy Setting and disabling the Disable Indexer Backoff setting and restarting the Windows Search service, the indexer still seems to clog my PC's performance at full speed, so the indexer not working as expected. Back then it used to say "Indexing speed is reduced because of user activity." and not eat up so many resources but now it doesn't do that, my indexer backoff is on in so many ways and it still doesn't display that sentence when indexing.

I'd like to note that I have not changed anything related for this to happen, as in, only after a couple of Windows 11 updates and having indexer backoff disabled for a long time, when I decided to enable it, it still doesn't work. It used to work completely normally, last time almost half a year ago. I have thoroughly researched similar problems but couldn't find a satisfactory solution. How can I fix indexer backoff not reducing indexing speed despite being enabled? If anyone has encountered a similar issue or has expertise in this area, I would greatly appreciate your guidance and suggestions.

Thank you in advance for your help!

Do try letting indexing complete once and then seeing if Indexer backoff starts working as it should.

I have never experienced indexing inhibiting computer performance so I agree with dalchina that what you are seeing might be a symptom of a problem elsewhere [hardware, file system, ...].


Best of luck,
Denis
