For the following content, refer to some onlineArticleIn addition, you may be at your own risk.

The main method is to remove some installation and trial time information under the VA record. There are three places where va records the information.
Items:

1) HKEY_LOCAL_MACHINE \ SOFTWARE \ licenses

2)
HKEY_LOCAL_MACHINE \ SOFTWARE \ Classes \ CLSID \ {ACABBB00-02A4-CF3E-B293-188330493F10}

{Xxx...} may be different for different versions and machines, such
{ACABBB00-02A4-CF3E-B293-188330493F10} is the value on my XP Virtual Machine, and on my actual machine is
{2401839d-8a0e-f7a3-3a39-201eb8e3078d }.

Browse
HKEY_LOCAL_MACHINE \ SOFTWARE \ Classes \ CLSID \
Visual assist installation time (3 ~ 10, related to specific machines, and other software)
Check one by one. One subitem is irregular, and others are compared with the rule. For example:

{ACABBB00-02A4-CF3E-B293-188330493F10}
Fmnvzvrluw
Paowhf
Jvielmgrzqpm
Durvunbfybvl
Psohy
Wqgi
Zydrzwfqwyfs
Inprocserver32

Others are generally
{XXXXXXXX ...}
Description
Inprocserver32
Progid
Versionindependentprogid

And so on, actually the target item {ACABBB00-02A4-CF3E-B293-188330493F10} is VA's time information record, of course
Only the VA knows its format. to hide your ears, {ACABBB00-02A4-CF3E-B293-188330493F10} again
Merge another random registered CLSID, so when you see
Inprocserver32 under {ACABBB00-02A4-CF3E-B293-188330493F10} seems to be another feeling
It is very important, I think, if you search under HKEY_LOCAL_MACHINE \ SOFTWARE \ Classes \ CLSID \
Then, you should search for its real entries.

Find
HKEY_LOCAL_MACHINE \ SOFTWARE \ Classes \ CLSID \{ ACABBB00-02A4-CF3E-B293-188330493F10
}

3) temporary files in your temp user variable % USERPROFILE % \ Local Settings \ Temp
1489afe4. tmp.
If your temp user variable is set to another place (for example, in F: \ temp \ utemp ),
Find this file. The modification time and creation time of this file are similar to those of VA installation time.
. The specific file name may be related to the version.
Of course, you can also clear all the directories. In general, there should be no problem.

The information recorded in the above three parts should be the same, and none of the above will be able to succeed during the cracking. When VA is uninstalled
The information is retained, and the method of uninstalling VA and reinstalling it does not work. Even if you reinstall the system
If the variable directory is set to a previous location and has not been cleared, the Registry is completely new and useless.

The following is a simple batch processing example. You may need to modify some data based on your own situation and version.

Disable Visual Studio when vaclean is running.

####################### Vaclean. start with cmd #######################

@ Echo off

Rem fill in the two items as appropriate values.
Set cid = {2401839d-8a0e-f7a3-3a39-201eb8e3078d}
Set TPF = "F: \ temp \ utemp \ 1489afe4. tmp"

Reg Delete HKEY_LOCAL_MACHINE \ SOFTWARE \ licenses/F
Reg Delete HKEY_LOCAL_MACHINE \ SOFTWARE \ Classes \ CLSID \ % CID %/F
Del/Q % TPF %

Echo.
Pause

####################### Vaclean. CMD end #######################

The above test is based on
Visual assist x 10.3.1535.0
Visual assist x 10.3.1534.0 (earlier versions and later versions of this method may be valid)
And
Visual c ++ 6
Visual Studio 2005
And
XP SP2
