Windows Booting very slow after 2004 update ,

I have the same issue, i had to restore my computer to before the update because was awful the performance of my pc and i'm afraid to update my laptop which i use to work

Thank you.  It worked, but the scan didn't find anything.

No, CTRL+SHIFT+ENTER will not work. The easy way to get CMD (or powershell, gives same result for doing commands), is to press the Windows key on the keyboard, then while holding it, quickly press the X key, let go both then press the A key. This will open a UAC (is is ok to proceed) window, just asking if Administrator mode is OK, click the YES box. You should then get either a Command Prompt (black window), or a Blue window, that is Powershell (it depends on how your system was configured), then key in your sfc  /scannow command (note the space needed between the sfc command and the qualifyer, that is needed, or it will not recognise it as a proper command).

When it is all completed (may take a while, so don't think it has hung at 66% and 86% or so, give it time to finish). If it asks for the PC to be retarted, do that, but if not and it DOES fix something, reboot anyway. Note that the command exit will close the cmd or Powershell window.

Hello, John

My computer has become insanely slow since the last update (Version 2004).  I followed your instructions as far as entering sfc/scannow at the command prompt, but my computer says I am not an administrator, even though I did CTRL+SHIFT+ENTER like you said, and my user profile also says I am an administrator.  I am the only person who uses this computer, so no one else could possibly be an administrator.   Do you have any idea what the problem might be?  Thank you very much.

Hi @GeorgeCB10 - that was from my post about stopping those 3 services. The quick way to get the services control tool is to right-click on the START MENU BOX bottom left, choose RUN, then key in services.msc then click on OK. It uses the same method (stop the service, then click on the properties for the service in question, then choose Disable for the SysMain and Windows Search, but the Windows Media Player Network Sharing one, IF THERE, you can just leave it as MANUAL once stopped), and it will be one of those in the list.

If you do NOT use Windows Media Player, or do not have Media Streaming turned on, then it may well NOT be there in the list anyway, so you can ignore that step. The Media Player is usually there on those machines that were upgraded from Wndows 7 to indows 10, and not usually on systems that had Windows 10 to start with.

Hi TD47 - I do have Windows Media Player which I use occasionally. I'm not sure what Media Steaminf is though.

I updated to Windows 10 2004 yesterday and had enormous difficulties get my laptop to boot up - it kept freezing on a blank screen. The update took hours and my laptop is noticeably slower. I notice that there is an option to undo the last upgrade but I'm not sure where or not to do this for fear that I might make matters worse - that is why I thought LucianMinea's suggestion of disabling the SySMain and Indexing services might do the trick. But, as I said, I am confused about the Windows Media Player additional option that you mentioned.
