It is possible to fix this without reinstall system?

%SystemRoot%/system32/spool/DRIVERS/ paths... will try to clean it...

Well I learned a long time ago, sometimes it just a heck of a lot easier and faster to just cut your loses and do a reinstall and be done with it, instead of spending hours and hours trying to p*** in the dark..

It will be easier for me to write small tool for clean registry and use it with livecd... I have lot of big software installed, and restoring all can kill much time...

yor NVIDIA GeForce GT 555M maybe the cause. There is a topic on Technet where users also have large CONFIG folder:

A solution is to stop the "NVIDIA Stereoscopic 3D Driver" service.

Problem solved. I wrote simple tool that do scan and remove unused keys (with exclusions of default keys and keys with existing paths). I used WinPE to clean hive. I loaded bloated hive (it was loading about 10min too) and used my tool. It removed 4300000+ keys in total. Then I reexport this hive into new file to reduce size and defragment hive, (now it weight 150mb). After this just replaced bloated hive by new one. Now all is good . .blf and .regtrans-ms files I just removed (they not affectted on boot time)
I think that reason of problem was glitched spooler servise (one time i found that it eat my cpu, may be it was installing phantom printer drivers that created these junk keys).
Big thanks for all.

[MagicAndre1981]

nice to hear that you fixed it

What is now the complete boot time?

[kmz7]

This is an updated tutorial of my Windows 7 here.

To get started you need the Windows Performance Tools Kit. Read here how to install it:

http://www.msfn.org/...howtopic=146919

Now open a command prompt with admin rights and run the following commands:

For boot tracing:

xbootmgr -trace boot -traceFlags BASE+CSWITCH+DRIVERS+POWER -resultPath C:\TEMP

Note, in Windows 8 it is safe to use the DRIVERS flag, the Windows 7 bug is fixed in Windows 8.

For shutdown tracing:

xbootmgr -trace shutdown -noPrepReboot -traceFlags BASE+CSWITCH+DRIVERS+POWER -resultPath C:\TEMP

For Standby+Resume:

xbootmgr -trace standby -traceFlags BASE+CSWITCH+DRIVERS+POWER -resultPath C:\TEMP

For Hibernate+Resume:

xbootmgr -trace hibernate -traceFlags BASE+CSWITCH+DRIVERS+POWER -resultPath C:\TEMP

replace C:\TEMP with any temp directory on your machine as necessary to store the output files

All of these will shutdown, hibernate, or standby your box, and then reboot to finish tracing. After you login to your PC, the new startscreen is shown and you have to click to the desktop to see countdown timer. Again, wait until the timer finishes. Afetr you did this you should now have some tracing files in C:\TEMP.

Analyses of the boot trace:

To start create a summary xml file, run this command (replace the name with the name of your etl file)

xperf /tti -i boot_BASE+CSWITCH+DRIVERS+POWER_1.etl -o summary_boot.xml -a boot

Now you see this picture.:



Hi MagicAndre1981,
I found your post while searching for ways to speed up my windows 8 boot time. It used to be around 10 seconds but now takes about 66 seconds or more, while Soluto said it takes about 1:27 for a full boot.
I did all of the steps, downloaded the Windows Performance Tools Kit. I got up to that last step that I quoted you on, because I have no idea how to "create a summary xml file and run it in the command." I desperately want to speed up my boot time. I would love for you to help me!
Also, I have noticed the last few days that my computer sort of freezes between the dell black screen and the start screen which never happened before. The screen is just greyish black for about 30-40 seconds. =/

[MagicAndre1981]

zip the ETL file and upload the zip (skydrive, dropbox) and send me a link.

[BDelsol]

Hi,
Thank you for your quick response.
But I have no clue how to zip the ETL file or what it is. Where do I find it?

Zip is a file format to reduce the file size:

http://en.wikipedia....8file_format%29

Install a tool like 7-zip, go to C:\temp and create a zip file of the file fastStartup_BASE+CSWITCH+DRIVERS+POWER_1.etl or boot_BASE+CSWITCH+DRIVERS+POWER_1.etl (depending if you tarced the old school or the news fast Boot)

[BDelsol]

I know what a zip file is but I have no idea where to find C:\temp? Can you please guide me the right way? I am sorry, I am not the best at these things but I appreciate all of your help and patience. =)

[BDelsol]

Oh never mind, I found the file. =D I made a zip folder. I am going to upload it to skydrive!

Magic Andre,
Check you private messages! Sent you the link. = )

[MagicAndre1981]

the delays happen because of:

1st: RequestCredentials takes 11s. So enter the password faster and if you use a LiveID/MS Account,make sure you have Internet Access so that the PW gets validated faster.
2nd: you run too many tools at startup. Remove useless tools like Vit Registry Fix, Revo Uninstaller, Soluto, Eusing Free Registry Cleaner, Find Junk Files, Auslogics Disk Defrag and System Ninja.

You use so much crap tools which only damage your PC.

[BDelsol]

Guilty. I am obsessed with cleaning my computer. lol
But either way I have made sure that none start at startup. How come they still are? Can you help me fully remove them from boot time since none of the programs you listed show up on my services or startup manager? Will uninstalling do the trick?

But what about the credentials request? I don't have any passwords set on my computer...?

Thanks in advance! =)

[MagicAndre1981]

The boot prefetcher shows a lot of misses with all the tools I mentioned. Best is to use Refresh (http://windows.micro...efresh-reset-pc) Windows 8 which kills all desktop applications. Now only install the desktop tools you really need and not those buggy crap applications.

[BDelsol]

Do you think by doing this, will it get me back to when the computer was brand spanking new? : )
Also, I would like to do a refresh but I am scared I will loose some programs I need for school. Does it kill all applications and software I have installed?

Thanks again for all of your help! = )

[MagicAndre1981]

refresh renews Windows so that it is stable again. The refresh removes all desktop applications, so you have to reinstall them.
