Fix: Teams MTR Hard Drive Is Full Without Reason

I recently came across this issue in our MTR.

we found C drive is full without reason.

we downloaded TreeSize software (free) to find what makes our C drive full.

Link to download TreeSize software - Click Here

we found Windows.edb file with a size of 90GB.

The Windows.edb?file is a hidden file, located in the following folder:

C:\ProgramData\Microsoft\Search\Data\Applications\Windows\Windows.edb        

You can check the current size of the Windows.edb file with the following PowerShell command:

((Get-Item $env:programdata'\Microsoft\Search\Data\Applications\Windows\Windows.edb').length/1GB)
        

Next, let’s look at several ways to reduce the size of the huge Windows Search Index (Windows.edb) file.

How to Reset and Rebuild Windows Search Index?

open?Control Panel -> Indexing?Options -> Advanced ->?click?Rebuild

Remove and Recreate the Windows.edb file

?To delete the Windows.edb file, stop the?Windows Search?service, then delete the file and start the service.

net stop "Windows Search"
REG ADD "HKLM\SOFTWARE\Microsoft\Windows Search" /v SetupCompletedSuccessfully /t REG_DWORD /d 0 /f
del %PROGRAMDATA%\Microsoft\Search\Data\Applications\Windows\Windows.edb
net start "Windows Search"
        

The value of the registry parameter?SetupCompletedSuccessfully = 0?in the reg key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Search forces the Windows Search service to reset the current settings and indexing paths at the next start, restore the default wsearch parameters and add the default indexing paths.
