Windows 10: Lenovo desktop does not start after Windows 10 update

My Lenovo desktop does not start after a Windows 10 update yesterday.

Only the word Lenovo is shown on a black screen.

The computer was very slow in recent days.

Lenovo OneKey Recovery F2 does not work.

F1, the BIOS setup utility, works.

What I can do?

Lenovo Ready to Launch Windows 10 Devices

Lenovo today announced it will begin shipping a wide selection of products loaded with Windows 10 starting July 29. Lenovo has an extensive list of products eligible for this upgrade including popular models like the YOGA 3 Pro and YOGA 500. Lenovo customers can check here for their product's eligibility.

Lenovo has worked with Microsoft Corp. to make the process of upgrading simple, for people with qualified Lenovo PC running Windows 7 SP1 or 8.1 to upgrade to Windows 10. Starting on July 29, the updates will roll out. If a user has reserved a copy of Windows 10, he/she will be notified once the compatibility process confirms that the user will have a great experience, and Windows 10 has been downloaded on their system.





Lenovo Apps Enhance Windows 10 Experience
To give users consistent experiences across devices and operating systems, the preloads include a suite of Lenovo-written applications. The new Lenovo Companion 3.0 optimization tool keeps devices running at peak performance and can be used at any time to run a full-scale checkup and report back with specific actions to free up space and speed up the device. As a "smart" device control hub, the new Lenovo Settings lets users easily adapt and modify the way their device behaves. For example, when in tablet mode, the product will customize its display and other settings based on its orientation versus in traditional laptop mode. Alternatively, the device's usage will also alter its settings, for example when watching a movie versus reading an e-book. With SHAREit, customers can quickly transfer files between devices. For tablet users WRITEit takes the pen to a new level of functionality allowing users to write in any input field with their pen and the handwriting is converted to text.

As announced at Tech World in May, Lenovo and Microsoft have worked to integrate Cortana and REACHit, Lenovo's groundbreaking app that allows users who opt-in to search for and manage their content across multiple devices and cloud storage platforms. With REACHit, Cortana becomes even smarter and more personal, enabling users to find their content such as emails, photos and videos in ways they never thought possible. Cortana and REACHit gives users a seamless, intuitive way to search through natural language and contextual understanding.

"With Windows 10, computing gets more personal, productive and connected," said Tom Shell, senior vice president, PC Business Group, Lenovo. "Across our entire PC product line, from the office to the home, we've optimized our Lenovo devices to give customers a great computing experience while giving them enhanced search tools like Cortana with REACHit."

 

Windows Updates failed to instal

I'm not sure how differant XP media center Edition is but you could clear the history \ cache if these folders are there.

Step 1 Register DLL files.

=================

By trying this step, we can check if the update engines are working properly.



1. Close all instances of Internet Explorer.

2. Click Start and Run, type "Regsvr32 atl.dll" (without quotes) in the Open box and click OK.



Note: There is a space between regsvr32 and atl.dll



3. Similarly, one by one, register the files listed below:



Regsvr32 msxml3.dll

Regsvr32 wuapi.dll

Regsvr32 wuaueng.dll

Regsvr32 wuaueng1.dll

Regsvr32 wups2.dll

Regsvr32 wucltui.dll

Regsvr32 wups.dll

Regsvr32 wuweb.dll

Regsvr32 qmgr.dll

Regsvr32 qmgrprxy.dll

Regsvr32 jscript.dll



Note: If you encounter errors while registering any of these files then skip that file and continue with the next one.



If the issue persists, let's move on to the steps below to verify Windows Update services and temporary folders.



Step 2 Verify the relevant Windows Update services.

=========================================

1. Click Start->Run, type "services.msc" (without quotation marks) in the open box and click OK.

2. Double click the service "Automatic Updates".

3. Click on the Log On tab, please ensure the option "Local System account" is selected and the option "Allow service to interact with desktop" is unchecked.

4. Check if this service has been enabled on the listed Hardware Profile. If not, please click the Enable button to enable it.

5. Click on the tab "General "; make sure the "Startup Type" is "Automatic" or "Manual". Then please click the button "Stop" under "Service Status" to stop the service.

6. Then please click the button "Start" under "Service Status" to start the service.

7. Please repeat the above steps with the other services:



Background Intelligent Transfer Service

Event Log

Remote Procedure Call (RPC)



Note: Event log service is enabled on all of the hardware profiles; this service does not have an option to enable or disable on certain hardware profile.



If it still does not help, let's proceed to step 3.



Step 3 Reload the Update temporary folders.

===================================

One possible cause is that the temporary folder for Windows Update is containing corrupted files. Let's erase all the files there to get the system clean.



1. Click Start, Run, type: cmd and press Enter. Please run the following command in the opened window.



Net stop WuAuServ



2. Click Start, Run, type: %windir% and press Enter.

3. In the opened folder, rename the folder SoftwareDistribution to Sdold.

4. Click Start, Run, type: cmd and press Enter. Please run the following command in the opened window.



Net start WuAuServ



Please test the Windows Update website and let me know the result. If the issue persists, to clarify the issue and provide more accurate troubleshooting steps, please assist me in collecting the following information.

 

Windows 10 Tweaks

Pressing “Windows+Pause Break” (it’s up there next to scroll lock) opens the “System” Window.

Windows 10: In the new version of Windows, Explorer has a section called Quick Access. This includes your frequent folders and recent files. Explorer defaults to opening this page when you open a new window. If you’d rather open the usual This PC, with links to your drives and library folders, follow these steps:

• Open a new Explorer window.
• Click View in the ribbon.
• Click Options.
• Under General, next to “Open File Explorer to:” choose “This PC.”
• Click OK
