Windows will not release my externals drive - device is busy

We are getting spoiled with all those SSDs. A boot of more than 20 seconds is already considered slow.

Yep, I have one of those slow computers.

Yes, the data is in the Event Viewer > Event 100. Drill down this chain:

Eventvwr
Applications and Service Logs
Microsoft
Windows
Diagnostics - performance
Operational
Event ID 100

This will give you the overall time. Then click on the Details tab in the little window. That shows the individual processes. Best is to copy/paste that info into a Notepad for better reading.

Here are the details from my 20 second system for comparison:

Please tell me what program you use to show the "Windows Boot Time." Also, my SSD primary drive takes almost 5 full minutes to boot. Is there a program which can analyze what programs and services are causing this disastrous slowdown? Thank you............

Hi Nisko

I used Glary Utilities to get the graphic you saw there.

Glary Utilities - Download | Glarysoft

I have the Pro Version but I'm pretty sure the Plain version would give the information you seek.

As to the "disastrous slowdown", I would not have a clue. Stick around and one of our resident experts will surely read this and offer help.

Good luck to you.

Sorry it took so long for a Reply - been ill. Attached is my Event 100 detail - but I don't know how to read it. From this, can you tell me how to read it and what to look at to get my boot time down from almost 5 minutes? Thank you. Also, I had never heard of Glary Utilities until you mentioned it. The free version doesn't show the boot time as yours does. Is this a good utility package worth the money? There are so many out there!! Thank you...........

If I am reading it right, as you said your boot time is over 5 minutes.

You need one of the folks here to help you find out how to fix the problem. I am not qualified.

Hope someone else is seeing this thread.

Re: Glary Utilities, the Pro version does go on sale. I paid about $12 for the license and it covers 3 computers. You might check the web site often looking for a bargain.

I wish you well.

Re: External drives locked. I had the same problem. It was Explorer locking the drives. You can test that by killing explorer then restarting Explorer using Task Manager and then attempt to eject the drive. If it works it could just be a buggy shell extension. Also as mentioned your AV could be the culprit.
